    Variable Cylinder Management (VCM) deactivates 3 cylinders during light-load driving to improve fuel economy. When inactive cylinders reactivate, vacuum pulls oil past piston rings into the combustion chamber, causing excessive oil consumption (1 quart per 1,000-1,500 miles vs. normal 1 quart per 3,000-5,000). Oil burning causes spark plug fouling, misfires, rough idle, and accelerated catalytic converter wear. 2013 class action lawsuit identified 1.6 million affected Honda vehicles including 2006-2013 Ridgelines.

    This issue also affects: Acura ILX, Acura Integra, Acura MDX

    Common Symptoms

    • Excessive oil consumption (1 quart per 1,000-1,500 miles)
    • Engine misfire codes P0300-P0306
    • Fouled spark plugs with carbon buildup and wet deposits
    • Rough idle or hesitation
    • Check engine light illuminated
    • Blue or gray smoke from exhaust
    • Excessive engine vibration when VCM activates

    How to Fix

    Disable VCM using aftermarket devices: VCMuzzler II ($81), VCMTuner II ($150-$200), or S-VCM Controller ($180-$250). Check oil level every 500-1,000 miles until VCM disabled. Use synthetic 0W-20 oil. Replace spark plugs every 30,000-50,000 miles instead of 100,000. Severe engine damage may require rebuild ($4,000-$8,000).

    Owner tips & cautions

    • TipMonitor oil level obsessively and keep 2-3 quarts in vehicle for top-offs between oil changes
    • WarningInstall VCM disabler as preventive measure, not reactive - engine damage from oil consumption is permanent and expensive
    • TipReplace spark plugs every 30k-50k miles instead of 100k - fouled plugs cause misfires that damage catalytic converters ($1,500-$3,500)
    • TipDisabling VCM also protects engine mounts and transmission from excessive wear and vibration
    Typical repair cost:$81 - $8,000

    The 3.5L aluminum engine with steel spark plugs experiences thermal stress due to temperature differences. Spark plugs back out (loosen) due to aluminum block expansion/contraction cycles, causing misfires and potentially breaking inside the combustion chamber. Loose spark plugs allow coil packs to melt and enter the engine block causing catastrophic damage. After 60,000 miles, Honda service bulletins specify spark plug torque should be double-checked. Affects all J35 engine platforms (Pilot, Odyssey, Ridgeline).

    This issue also affects: Acura Integra, Acura MDX, Acura RDX

    Common Symptoms

    • Misfire codes P0300-P0306
    • Check engine light
    • Rough idle or hesitation
    • Coil pack melting or burning visible in cylinder
    • Complete engine failure if melted coil enters combustion chamber
    • Engine won't start (broken/loose plugs)

    How to Fix

    At 60,000 miles: remove spark plugs and re-torque to proper spec (18 ft-lbs) using torque wrench. Inspect each plug for backing out or looseness. Use OEM Honda spark plugs only. Coil pack replacement if melted: $150-$300 per coil + labor. Engine head repair if melted coil damaged head: $1,500-$3,000+. Full engine rebuild if catastrophic: $4,000-$8,000+.

    Owner tips & cautions

    • TipUse torque wrench when installing spark plugs - do not over-tighten (18 ft-lbs spec exactly)
    • TipAlways work on engine when completely cool - aluminum expands significantly when hot and causes incorrect torque readings
    • TipCheck spark plug torque at 60,000 miles and every 30,000 miles thereafter as preventive maintenance
    • WarningHave coil packs inspected immediately if misfire codes appear - replacing coils early prevents catastrophic $4,000+ engine damage

    The 2006-2014 Ridgeline's J35A9 uses a belt-driven cam system with a hydraulic (oil-filled) timing belt tensioner rather than a spring tensioner. The tensioner seal weeps, the damper loses its charge, and belt tension goes slack. Ridgeline Owners Club threads report technicians finding a large share of high-mileage tensioners leaking. A slack belt lets the belt jump a tooth on a cam sprocket - first showing up as a random misfire under load - and if it skips far enough or shears, the J35 is an interference design and bends valves. The water pump is driven off the same belt and is a common co-failure, so a leaking tensioner discovered late often means the whole front of the engine.

    This issue also affects: Acura Integra, Acura MDX, Acura RDX

    Common Symptoms

    • Oil weeping from the hydraulic timing belt tensioner / lower timing cover
    • Rattle or slap from the timing belt area on cold start
    • Random misfire under load
    • Check engine light
    • Rough running or no-start after belt skip

    How to Fix

    Replace the timing belt as a complete job at or before 105,000 miles / 7 years, and always replace the hydraulic tensioner, tensioner pulley, idler pulley, water pump, drive belt and cam/crank seals at the same time - never belt-only. Inspect the lower timing cover for oil residue at every oil change; wet residue at the tensioner is a leak, not a drip from above. Dealer pricing for belt + tensioner + water pump has run roughly $900-$1,700; a skipped belt on this interference engine runs $4,000-$5,000+ in valve, head and piston work.

    Typical repair cost:$900 - $5,000

    NHTSA investigation EA25-004 covers 2.2 million Honda vehicles including 2020-2023 Ridgeline for idle stop and go (ISG) system failure to restart engine after automatic shutdown at stop lights. Vehicle may fail to automatically restart when stop ends, requiring driver to manually restart by shifting to Park and pressing ENGINE START/STOP button. Honda released TSBs 23-008, 23-009, 23-010 with two-stage remedy: Stage 1 involves PCM software update; Stage 2 (if software fails) involves starter assembly or relay replacement with 10-year unlimited mileage warranty extension. Despite repairs, NHTSA continues receiving complaints of failures even on vehicles with TSB applied.

    Common Symptoms

    • Engine fails to automatically restart when traffic resumes
    • Requires manual restart by pressing ENGINE START/STOP button
    • Intermittent failures (sometimes restarts, sometimes doesn't)
    • Check engine light appearing with starting system codes

    How to Fix

    Stage 1: Visit Honda dealer for PCM software update (free under warranty) - TSB 23-008, 23-009, 23-010 references. Labor: 1-2 hours. Stage 2 (if software doesn't resolve): Replacement of starter motor or related relays. Starter replacement: $300-$500 + labor. Relay replacement: $50-$150 + labor. Free if within extended warranty (10 years unlimited miles per TSB). Out-of-warranty cost: $350-$800.

    Owner tips & cautions

    • TipGet TSB updates completed as soon as possible - Stage 1 software update solves many cases at no cost
    • TipDocument all ISG failures with date, time, temperature, and traffic conditions for warranty escalation if issues continue
    • TipDisable ISG manually if experiencing repeated failures - use infotainment settings (workaround, not fix)
    • TipKeep battery in excellent condition - weak battery may exacerbate ISG restart issues
    • TipReport continued failures to Honda corporate after TSB completion - NHTSA investigation ongoing and additional recalls may be forthcoming
    • WarningDon't ignore issue - inability to restart at traffic light creates traffic safety hazard and intersection blocking

    Honda Sensing collision mitigation braking system (CMBS) gives false alarms and phantom braking, particularly during left-hand turns through intersections with opposite traffic, and on windy roads. The forward collision warning also fails to alert in actual collision scenarios. NHTSA investigation EA21-005 covers 2017-2022 models (focus on Accord/CR-V but Ridgeline also affected). ODI received 1,294 consumer complaints regarding unexpected AEB activation, with data indicating 47 crashes and 93 injuries potentially linked to phantom braking. Honda attributed some issues to radar positioning.

    Common Symptoms

    • Sudden automatic braking when no obstacle present (phantom braking)
    • False collision warnings during turns
    • Braking triggered on windy roads
    • System brakes when turning left through intersection
    • Forward collision warning fails when actual collision imminent
    • Inconsistent system behavior
    • Unexpected deceleration in traffic

    How to Fix

    Contact Honda dealer for radar re-calibration/repositioning (available free under warranty). Honda software updates address some phantom braking scenarios. Radar sensors may need replacement if defective: $400-$600. Full Honda Sensing system recalibration: $200-$400 labor. Some owners disable system via infotainment menu if persistent issues (reduces safety features).

    Owner tips & cautions

    • TipMany owners reported phantom braking on Ridgeline forums - request radar re-calibration at dealer as this has resolved many reported cases
    • TipDon't dismiss false braking as driver error - issue is real and documented in 1,294+ NHTSA complaints with 47 crashes
    • TipDocument phantom braking incidents with location, weather, and driving conditions for warranty claim support
    • TipSoftware updates released - ensure dealer updates your vehicle to latest Honda Sensing version to reduce phantom braking
    • WarningWindy weather and left turns through intersections are known trigger scenarios - be prepared for unexpected braking
    • TipNHTSA investigation EA21-005 ongoing - stay updated on future TSBs or recalls that may be issued

    Every 2006-2014 Ridgeline is covered by the Takata ammonium-nitrate inflator recall campaigns. The propellant degrades with age and with cycles of heat and humidity; a degraded inflator can over-pressurize and burst its metal housing during deployment, firing shrapnel into the cabin. NHTSA and Honda have repeatedly warned that the oldest inflators - including ones covered under the original Honda recalls 08V-593, 09V-259, 10V-041 and 11V-260 that were never brought in - carry the highest rupture risk, and Honda has told owners of the worst-risk vehicles to drive them only to the dealer. Because these trucks are now on second and third owners, the completion rate on the oldest campaigns remains the problem: many are still unrepaired.

    Common Symptoms

    • Open Takata recall shown on a VIN lookup
    • SRS warning light on
    • Vehicle bought used with unknown recall history

    How to Fix

    Run the VIN through the free NHTSA recall lookup at nhtsa.gov/recalls or Honda's owner site. Replacement inflators are free with no mileage or age limit and the job is typically under two hours. Do not carry front passengers in an unrepaired truck, and never install a used or salvage-yard airbag module from another first-gen Ridgeline - it may be an unremedied Takata unit.

    On first-generation (YK1) Ridgelines, road salt, mud and debris pack into the boxed rear frame rails around the fuel tank strap mounts and the forward rear-subframe mounting points. Because the area holds moisture and was inadequately protected from the factory, the metal corrodes from the inside out. In advanced cases the fuel tank strap anchors rust away entirely and the tank can drop, and the front of the rear subframe can separate from the frame - a total loss of vehicle control. Honda recalled about 112,000 trucks in 23 salt-belt states and DC (22V-430). Owners on the Ridgeline Owners Club recall thread report dealers finding perforation well beyond what the inspection procedure anticipated, and the repair procedure itself (cutting, welding reinforcement plates, cleaning and waxing the rails) is extremely labor-intensive.

    Common Symptoms

    • Flaking or perforated metal on the rear frame rails near the fuel tank
    • Fuel smell or fuel leak
    • Clunking or shifting feel from the rear end
    • Fuel tank straps hanging loose
    • Failed state safety inspection for frame rot

    How to Fix

    Have the VIN checked at nhtsa.gov/recalls and get the free recall inspection. Depending on severity the dealer either applies anti-corrosive wax plus a reinforcement brace, or welds reinforcement plates. If the corrosion is too advanced to repair, Honda has been repurchasing trucks. Outside the recall states, the preventive fix is annual undercarriage washing, flushing debris out of the rear frame rails, and applying an oil-based rust inhibitor (Fluid Film / Woolwax) to the rear frame section before rot starts.

    The Ridgeline's unique in-bed trunk has drainage holes and weep holes designed to channel water out. These drainage holes frequently clog with leaves, pine straw, tree debris, pollen, and mildew. When clogged, rainwater and vehicle washing accumulate inside the trunk, causing rust, odor, and rendering storage unusable. The trunk gutter channel and lower perimeter drain holes require periodic cleaning. Some cases involve improper latch alignment or twisted weatherstripping seals.

    Common Symptoms

    • Inches of standing water inside in-bed trunk after rain
    • Water that won't drain after car wash
    • Musty smell from trunk area
    • Rust and corrosion visible inside trunk
    • Debris and leaves accumulating in water
    • Water dripping from trunk while driving

    How to Fix

    Preventive maintenance: inspect and clean all 10 bed drainage holes and trunk perimeter weep holes quarterly. Clear gutter channel around trunk opening of debris. Clean small drain holes at bottom of gutter channel. Verify trunk latch alignment - improper alignment prevents seal closure. Inspect and replace weatherstripping seals if twisted or loose ($50-$150). Dealer inspection: $100-$200.

    Water dripping from the overhead console or pooling on the headliner is a recurring Ridgeline complaint separate from the in-bed trunk leak. Two mechanisms show up on the owners club: the moonroof cassette's front drain tray plugs with pine needles and debris so the tray overflows onto the headliner instead of draining down the A-pillar, and the drain tubes themselves pop off or split at the pan connection. On second-generation trucks owners have also traced wet headliners to cracked factory seam sealer under the roof-rack rail / rain channel trim, which lets water in above the headliner with the moonroof drains working perfectly. Left alone the water rots the headliner, corrodes the overhead console wiring, and soaks the A-pillar airbag area.

    Common Symptoms

    • Water dripping from the overhead console or map lights
    • Wet or stained headliner
    • Water pooling in the sunshade trough
    • Damp front carpet or A-pillar trim
    • Musty smell in the cabin

    How to Fix

    Test the drains first: pour a small amount of water into each front corner drain hole - it should immediately drip out behind the front wheel. If it doesn't, clear the tubes with low-pressure air or a trimmer line (never a stiff wire that can puncture the tube) and reseat any disconnected tube at the drain pan. Make drain cleaning an annual item if you park under trees. If the drains flow but the headliner still gets wet, pull the roof-rack rail covers and inspect the factory seam sealer at the rain channel; reseal with urethane seam sealer. Dry the headliner completely to prevent mold.

    The Ridgeline's signature dual-action tailgate uses two separate latch mechanisms plus an electric actuator, and the swing-open function fails far more often than the fold-down one. Two distinct failure modes show up across generations: the electric latch actuator motor dies (the tailgate clicks but never releases, or is silent), and the internal actuating rods drift out of adjustment or corrode so the side latch never fully disengages. Owners of both YK1 and 2G trucks report the tailgate folding down normally while refusing to swing, which also blocks access to the in-bed trunk. Salt-belt trucks add latch corrosion on top.

    Common Symptoms

    • Tailgate folds down but will not swing open
    • Clicking from the tailgate with no release
    • No sound at all from the tailgate when the handle is pulled
    • Tailgate opens only intermittently or in one mode
    • In-bed trunk inaccessible

    How to Fix

    Start with the free steps owners report success with: clean and lubricate both latch assemblies and all contact points with a penetrating lubricant, then a dry film lube. If the actuator is silent when the button is pressed, check the fuse and the tailgate wiring harness at the hinge - the harness flexes there and chafes - before condemning the actuator. If the actuator runs but the gate won't release, the inner trim panel comes off and the actuating rods are bent slightly to restore travel, which is the documented dealer fix. A failed latch/actuator assembly is replaced as a unit.

    The radiator internal cooler corrodes at seams and fittings, allowing coolant to mix with transmission fluid in a condition known as "SMOD" (Strawberry Milkshake Of Death). This coolant contamination destroys all clutch packs and friction materials in the 5-speed transmission. 2006-2008 models see highest failure rates, particularly in rust-belt states past 80,000-120,000 miles. Unlike manufacturer recalls, Honda did not formally recall despite numerous failures.

    Common Symptoms

    • No drive or reverse suddenly
    • Transmission refuses to engage gears
    • Pink or milky transmission fluid (coolant mixed with ATF)
    • Rough shifting before complete failure
    • Transmission overheating
    • Loss of power during acceleration

    How to Fix

    Proactive radiator replacement at 100,000 miles as preventive maintenance ($300-$600). If SMOD has occurred: full transmission rebuild or replacement ($4,000-$6,000). Use Honda ATF 3.1 or equivalent. Many owners replace radiator every 100k miles as insurance policy.

    AWD Ridgelines experience noise and juddering from the rear differential, particularly when turning. The differential fluid breaks down prematurely due to contamination from clutch wear debris, condensation, or water intrusion. Water can enter through the breather tube vent in the rear subframe, especially after launching boats or driving through deep water. Low or contaminated differential fluid causes clutch noise and binding on turns.

    Common Symptoms

    • Humming or whining noise from rear axle
    • Judder or binding when turning
    • Clicking noise during turns
    • Vibration in rear end during cornering
    • Metallic grinding sound from rear
    • Noise increases with temperature

    How to Fix

    Replace rear differential fluid with Honda DPSF (Dual Pump System Fluid): 2 quarts needed ($40-$60 for fluid) + labor ($80-$120) = total $120-$180.

    The ZF 9HP-based 9-speed automatic fitted to 2020+ Ridgelines uses dog clutches rather than friction packs for some ratio changes. The dog clutch must synchronize gear speeds before it engages, and the PCM cuts engine torque during the event; when the calibration timing drifts the driver feels a hesitation, a lurch, or a hard bang on deceleration. Ridgeline Owners Club threads document harsh shifts while coasting or descending grades, a momentary loss of engine braking on manual 5-4 downshifts, and noticeably poor shift quality until the fluid is warm. This is distinct from the 10-speed programming complaint - it is the 9AT's dog-clutch architecture and cold-fluid behavior.

    This issue also affects: Acura CL, Acura ILX, Acura MDX

    Common Symptoms

    • Hard or banging shift when decelerating or coasting
    • Hesitation from a stop or when accelerating from low speed
    • Momentary loss of engine braking on manual downshift
    • Poor shift quality until fully warmed up in cold weather
    • Random or unrequested gear changes

    How to Fix

    Have the dealer apply the latest TCM/PCM software update - Honda has released multiple recalibrations for this unit and most cases are software, not hardware. A fluid service with the correct ZF-spec Honda ATF (not DW-1) restores shift quality on higher-mileage trucks; many owners service it at 30,000-60,000 miles despite the lifetime-fill claim. Avoid manual downshifts into the dog-clutch gears on grades; use the brake instead. Slipping, flare, or a stored ratio-error code means internal repair or valve body work, which is warranty territory.

    Second-generation Ridgelines with the 6-speed automatic (2017-2019, and the same 6AT family used in the Pilot and Odyssey) develop a shudder or judder that feels like driving over rumble strips during light-throttle cruise, typically 20-60 MPH when the torque converter clutch is slipping in its controlled-lockup mode. Honda's own TSBs 17-025 and 17-026 attribute it to ATF that degrades faster than expected because of intermittent high heat loads on the converter clutch. Owners report the judder returning after the first software-only attempt, which is why Honda issued the second bulletin covering vehicles that still judder after the update.

    Common Symptoms

    • Vibration or shudder during light acceleration at 20-60 MPH
    • Feels like driving over rumble strips
    • Judder worst at steady cruise or gentle uphill
    • Temporarily better after a transmission fluid change

    How to Fix

    Per TSB 17-025, update the PCM/TCM software and drain-and-fill the transmission with Honda ATF DW-1 twice. Per TSB 17-026, if judder persists after the update, repeat the drain-and-fill three times. Honda extended the torque converter warranty to 8 years/150,000 miles on some Pilot/Ridgeline units - check coverage before paying. Owners who keep the truck long-term report doing a DW-1 drain-and-fill every 20,000-30,000 miles instead of the severe-service interval keeps the judder from returning. If the update plus fluid service fails, the torque converter itself is replaced.

    Center console infotainment touchscreen goes completely black or becomes unresponsive on 2017-2023 models. System may enter infinite shutdown loop draining battery overnight. Software glitches across all model years and loose fuse connections cause complete audio/navigation system failure. Class action lawsuit (2019) alleged multiple defects including crashes, freezes, failure to start/shut down, and failure to connect to smart devices. Honda issued multiple TSBs starting November 2017, but plaintiffs claimed Honda unable to fix defects across multiple service attempts.

    Common Symptoms

    • Center touchscreen completely black with no display
    • Touchscreen frozen or unresponsive to touch
    • Infinite reboot loop while parked
    • Loss of radio, navigation, and climate controls
    • Battery drain when vehicle is off
    • System crash during use
    • Wireless connectivity failures

    How to Fix

    Check fuse box for loose fuse controlling infotainment - reseat if loose (common fix). Perform hard reset: hold power button 10 seconds or disconnect battery 10 minutes. Visit Honda dealer for software update (free under warranty) - TSB updates available. Persistent issues may need complete infotainment unit replacement: factory replacement $800-$1,500 + labor $200-$400 = total $1,000-$1,900. Aftermarket head unit option: $400-$800.

    Owner tips & cautions

    • TipCheck for loose fuse before assuming unit failure - very common and free fix that solves many black screen issues
    • TipHard reset sometimes resolves temporary glitches - try before dealer appointment (hold power 10 seconds or disconnect battery)
    • TipRequest Honda dealer TSB software update - free under warranty and resolves many issues without hardware replacement
    • TipDocument all system failures with photos/videos for warranty support - helps escalate case to Honda corporate if needed
    • WarningIf screen drains battery overnight, disconnect infotainment fuse until dealer repair to avoid being stranded with dead battery
    • TipMultiple service attempts by dealer common - may require escalation to Honda corporate for persistent issues beyond dealer capability

    The Ridgeline's front lower ball joint is pressed into the lower control arm and is not serviceable separately, so normal wear condemns the whole arm. Owners club threads on 1G trucks describe a clunk or knock from the front end over expansion joints and driveway lips, often misdiagnosed as struts. Because the truck carries a heavier front end than the Pilot it shares suspension architecture with, the lower arms, the rear compliance bushings in those arms, and the sway bar end links all wear early - and multiple owners report chasing the clunk through struts and end links before the ball joint or a loose subframe/arm fastener turned out to be the source.

    Common Symptoms

    • Clunk or knock from the front end over bumps
    • Popping when turning at low speed
    • Uneven inner tire wear
    • Loose or wandering steering feel
    • Play at the ball joint when pried

    How to Fix

    Diagnose properly before buying parts: with the truck on a lift and the suspension unloaded, pry-test each lower ball joint for play and inspect the rear compliance bushing in the arm for cracking and voiding. Re-torque the lower control arm frame bolts and subframe fasteners at ride height - several owners cured the clunk that way alone. The repair is a complete lower control arm assembly (ball joint included) per side, followed by a four-wheel alignment; separate the ball joint from the knuckle with a pickle fork after pulling the cotter pin and castellated nut. Sway bar end links and upper strut mounts are the other two common clunk sources - check them in the same visit.

    Ridgeline owners repeatedly report a crack that starts at the bottom edge of the windshield - usually in or near the wiper-park area where the heated de-icer element is bonded - and runs horizontally across the glass with no impact chip anywhere to be found. The pattern points to a stress fracture rather than road debris: thin OE glass, body flex from the unibody bed structure, and thermal stress from the lower defroster grid or from snow load sitting on the cowl. Threads on the Ridgeline Owners Club span both generations, with a concentration of 2017+ reports, and note that a windshield replacement also requires Honda Sensing camera recalibration.

    Common Symptoms

    • Horizontal crack along the bottom of the windshield
    • Crack appears overnight or after cold weather with no stone chip
    • Crack originates at the wiper rest area
    • Crack spreads across the full width of the glass

    How to Fix

    Cracks that reach the edge cannot be resin-repaired - the glass must be replaced. Many owners have had it covered under the new-vehicle warranty or by comprehensive glass coverage when no impact point exists, so document the absence of a chip before calling. Insist on OE or OE-equivalent glass with the correct heated wiper-park element and the correct camera bracket, and have the Honda Sensing camera statically recalibrated after installation or the lane-keep and collision-mitigation systems will misbehave. Clearing snow and ice off the cowl before running the defroster on high reduces thermal shock.

    First-generation Ridgelines whine loudly from the power steering pump on cold mornings, quieting as the engine warms. The cause is not usually the pump: the O-ring on the low-pressure supply hose at the pump contracts and hardens with age, letting the pump draw air past it and aerate the fluid. Honda addressed the noise in TSB 07-86. Ridgeline Owners Club members have repeatedly traced the whine to that single flattened O-ring, to a loose return-hose bolt, or to a clogged fine screen in the reservoir; separately, the high-pressure hose and the pump shaft seal are common age-related leak points on higher-mileage trucks.

    Common Symptoms

    • Loud whine from the engine bay on cold start that fades as it warms
    • Groaning while turning at low speed
    • Foamy or aerated power steering fluid
    • Power steering fluid level dropping
    • Fluid residue on the pump or high-pressure hose

    How to Fix

    Start with the cheap fix owners have proven out: replace the O-rings on both hoses at the power steering pump (a few dollars in parts) and torque the return-hose bolt. Remove and clean the reservoir - the internal fine screen clogs and starves the pump. Flush the system with Honda PSF-S (genuine Honda fluid only; ATF or universal PS fluid attacks the seals) using repeated turkey-baster changes. If the whine persists with good fluid and no air, or if you find fluid on the pump body or a cracked high-pressure hose, replace the hose and/or pump.

    What is the 2020-2026 Honda Ridgeline ZF 9-Speed (9AT) Dog-Clutch Hesitation and Harsh Coast-Down Shifts?

    The ZF 9HP-based 9-speed automatic fitted to 2020+ Ridgelines uses dog clutches rather than friction packs for some ratio changes. The dog clutch must synchronize gear speeds before it engages, and the PCM cuts engine torque during the event; when the calibration timing drifts th… Repairs typically run $0-$600. Severity: medium.

    What is the 2017-2019 Honda Ridgeline Torque Converter Lock-Up Clutch Judder at 20-60 MPH (6-Speed, TSB 17-025 / 17-026)?

    Second-generation Ridgelines with the 6-speed automatic (2017-2019, and the same 6AT family used in the Pilot and Odyssey) develop a shudder or judder that feels like driving over rumble strips during light-throttle cruise, typically 20-60 MPH when the torque converter clutch is… Repairs typically run $150-$2,500. Severity: medium.

    The Ridgeline's signature dual-action tailgate uses two separate latch mechanisms plus an electric actuator, and the swing-open function fails far more often than the fold-down one. Two distinct failure modes show up across generations: the electric latch actuator motor dies (the… Repairs typically run $0-$700. Severity: medium.

    What is the 2017-2024 Honda Ridgeline Windshield Stress Cracks Along the Lower Edge (Heated Wiper Zone)?

    Ridgeline owners repeatedly report a crack that starts at the bottom edge of the windshield - usually in or near the wiper-park area where the heated de-icer element is bonded - and runs horizontally across the glass with no impact chip anywhere to be found. The pattern points to… Repairs typically run $350-$1,200. Severity: low.

    What is the 2006-2014 Honda Ridgeline Power Steering Pump Cold-Start Whine and Feed-Hose O-Ring Leak (TSB 07-86)?

    First-generation Ridgelines whine loudly from the power steering pump on cold mornings, quieting as the engine warms. The cause is not usually the pump: the O-ring on the low-pressure supply hose at the pump contracts and hardens with age, letting the pump draw air past it and ae… Repairs typically run $10-$600. Severity: low.
