On the 2016-2022 Honda Pilot 3.5L V6, variable Cylinder Management (VCM) causes excessive oil consumption (1 quart every 1,000-1,500 miles), engine misfires, and fouled spark plugs. The reciprocating effect creates vacuum that pulls oil past piston rings. Leads to premature failure of spark plugs, catalytic converters, engine mounts, and cylinder walls. 2013 class action lawsuit identified 1.6 million affected vehicles.

This issue also affects: Buick LeSabre, Buick Park Avenue, Audi Q7

Common Symptoms

Excessive oil consumption (1 qt per 1,000-1,500 miles)
Engine misfires (P0300-P0306 codes)
Fouled spark plugs
Rough idle or hesitation
Check engine light
Excessive engine vibration when VCM activates
Blue smoke from exhaust

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 and top off as needed. Use synthetic 0W-20 oil. Replace spark plugs every 30k-50k miles instead of 100k. Severe cases may need engine rebuild ($4,000-$8,000).

On the 2016-2022 Honda Pilot, honda Pilots experience premature wear and failure of Active Control Engine Mounts (ACM), especially front and rear mounts. 2016+ Pilot uses 28-volt ACM system with sensors and actuators that cancel vibration. Rubber and metal components degrade due to heat, oil, and road conditions. VCM activation accelerates mount wear. Failed mounts cause excessive vibration, clunking noises, and visible engine movement.

This issue also affects: BMW M3, Cadillac Escalade, BMW X5 M

Common Symptoms

Excessive vibration in cabin at idle or during acceleration
Clunking or banging noises from engine bay
Increased vibration when shifting into gear
Shaking steering wheel
Engine appears to move excessively
Vibrations worse when AC or accessories engaged

How to Fix

Diagnose by shifting neutral to drive while engine running - if vibrations disappear in neutral, mounts need replacement. Replace both front and rear ACM mounts with OEM Honda parts ($250 each + $350-$500 labor = $1,200-$1,500 total). Aftermarket mounts ($60-$70) may not meet specs and cause continued vibration. Disable VCM to prevent accelerated wear.

On the 2003-2004 Honda Pilot 3.5L V6, early first-generation Pilot models share a well-documented 5-speed automatic transmission weakness with other Honda/Acura trucks of the era. Honda issued a safety recall to install an oil jet intended to improve lubrication/cooling of second gear because inadequate lubrication could lead to gear overheating, discoloration, breakage, and eventual transmission failure or lockup. Owners commonly report slipping, harsh shifting, flashing D4, burnt fluid, and complete loss of drive, sometimes even after the recall if damage had already begun.

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

Common Symptoms

slipping on acceleration
harsh or delayed shifts
flashing D4 light
burnt transmission fluid smell
loss of drive
shudder during shifting
transmission overheating

How to Fix

Verify whether the recall was completed and inspect for signs of overheated or contaminated ATF, delayed engagement, and shift flare. Scan the transmission control system for ratio and pressure-related codes, road test for slipping or flare on the 1-2 and 2-3 shifts, and inspect line pressure if needed. Mild cases may improve temporarily with repeated drain-and-fill using the correct Honda ATF, but many units ultimately require rebuild or replacement if second gear or the torque converter is damaged.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipIf the D4 light flashes or shifts become erratic, stop driving until fluid condition and transmission operation are checked; continued driving can rapidly turn a repairable issue into a full rebuild.
TipOwners often shorten ATF service intervals to roughly 25k-30k miles on early Pilots, especially if towing or driving in hot climates.

On the 2003-2008 Honda Pilot, on first-generation Pilots, repeated opening and closing of the rear hatch can fatigue and break wires inside the hatch harness near the hinge or rubber boot. Owners report intermittent or failed rear license plate lights, rear wiper, rear glass release, power lock, or tailgate-related electrical functions. The issue is typically caused by copper conductors fracturing inside intact-looking insulation.

Common Symptoms

rear hatch will not unlock
rear glass release inoperative
rear wiper not working
license plate lights out
intermittent tailgate electrical functions

How to Fix

Inspect the hatch harness where it flexes at the top of the liftgate, peeling back the rubber boot and tug-testing each wire. Repair involves soldering in new wire sections or replacing the damaged harness, then sealing the repair to prevent moisture intrusion. Because multiple circuits can fail at once, continuity testing each affected wire is usually faster than replacing individual components.

On the 2003-2013 Honda Pilot 3.5L V6, brake pulsation from front rotor thickness variation is one of the most commonly reported Pilot complaints across both generations. Owners describe steering wheel shake and pedal pulsation during highway-speed braking, often recurring after inexpensive pad-and-rotor jobs if hub runout, caliper slide condition, or lug torque is ignored. The Pilot's weight and heat load can make low-quality rotors especially prone to repeat judder.

This issue also affects: Chevrolet Uplander, Chrysler 300M, Chrysler LHS

Common Symptoms

steering wheel shakes when braking
brake pedal pulsation
vibration at highway speeds only during braking
recurrent front brake wear
hot brake smell after stops

How to Fix

Confirm the vibration occurs only during braking, then measure rotor thickness variation and check hub runout, caliper slide pins, and pad wear pattern. Replace rotors and pads with quality parts, clean rust from the hub face, lubricate slide pins, torque wheels evenly by hand to spec, and flush old brake fluid if caliper drag is suspected. If pulsation returns quickly, inspect for sticking calipers or rear brake imbalance contributing to front overheating.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipAsk the shop to measure hub runout and clean the hub face before installing new rotors; many repeat failures are caused by mounting surfaces, not just rotor quality.
TipAvoid impact-gun final tightening on lug nuts because uneven torque can contribute to rotor distortion and pulsation.

On the 2003-2013 Honda Pilot, wheel bearing wear is a widely reported Pilot problem across both generations, often showing up as a growling or humming noise that changes with road speed and steering input. On some vehicles, excessive bearing play or damage to the integrated wheel speed sensor tone ring can also trigger ABS or VSA warnings. Heavier curb weight and age appear to contribute to repeat bearing replacements on higher-mileage vehicles.

This issue also affects: Chevrolet Malibu

Common Symptoms

humming or growling noise that increases with speed
noise changes when turning left or right
ABS light on
VSA light on
wheel play or roughness

How to Fix

Road-test to isolate the noisy corner, then confirm with chassis ears or by checking for roughness/play with the wheel unloaded. Repair requires replacing the affected hub/bearing assembly or pressed-in bearing depending on axle position and generation, followed by alignment checks if suspension components were disturbed. If ABS/VSA lights are on, inspect the wheel speed sensor and tone ring during bearing service.

On the 2003-2011 Honda Pilot 3.5L V6, a very common Honda V6-era issue is power steering pump noise caused by suction-side air intrusion, often from a hardened inlet O-ring or aging pump seals. Owners report a cold-start groan or whining noise, visible bubbles in the reservoir, intermittent heavy steering, and fluid seepage around the pump. If ignored, the pump can wear out and steering assist may become inconsistent, especially in cold weather or parking maneuvers.

This issue also affects: Chevrolet Uplander, Chrysler 300M, Chrysler LHS

Common Symptoms

whining or groaning when turning
foamy power steering fluid
hard steering when cold
fluid seepage near pump
noise at idle
intermittent loss of steering assist

How to Fix

Inspect the reservoir for foamy fluid and check the pump inlet O-ring, hoses, and pump body for leaks or seepage. Replacing the inlet O-ring is a low-cost first step and often cures the noise if caught early; otherwise the pump may need replacement and the system should be bled thoroughly with the correct Honda-compatible fluid. Also inspect the return hose and reservoir screen if noise persists after pump service.

What Owners Are Using

On the 2016-2022 Honda Pilot, the Omron A/C clutch relay (Honda part 39794-SDA-A03) is defective and gets hot, causing failure. Honda-specific part with reduced coil current known to be problematic. When relay fails, either battery dies overnight (relay stuck closed) or AC stops working (relay stuck open). Low refrigerant from pressure relief valve venting can lead to failed AC compressor.

Common Symptoms

AC not blowing cold air
AC works intermittently
Battery drain overnight when parked
AC compressor not engaging (no click when AC turned on)
Squeaking noise from compressor clutch
Low refrigerant / refrigerant leak

How to Fix

Replace defective Omron relay (39794-SDA-A03) with updated Mitsuba relay (39794-SDA-A05) at dealer ($20-$40 part + $50-$100 labor) or DIY (relay in engine bay fuse box). If AC still not working, check refrigerant level and recharge ($150-$200). If clutch physically failed, full compressor replacement required ($1,200-$1,900).

On the 2003-2008 Honda Pilot, first-generation Pilots commonly develop coolant leaks from the plastic radiator end tanks or crimp seams as the radiator ages. Owners often notice a sweet smell, coolant residue on the radiator side tanks, or a gradual drop in coolant level before an overheating event. If ignored, the leak can worsen quickly and cause engine overheating, especially in hot weather or stop-and-go driving.

Common Symptoms

coolant smell from front of vehicle
low coolant reservoir level
visible coolant leak near radiator tank seam
engine temperature rises in traffic
steam from front grille area

How to Fix

Pressure-test the cooling system when cold and hot, inspect the radiator side tanks and upper seam for seepage, and verify the cooling fans operate correctly. The standard repair is radiator replacement, usually along with fresh coolant and often new upper/lower hoses and radiator cap if aged. Any overheating incident should be followed by checks for head gasket damage and cooling system air pockets.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipMany owners replace the radiator proactively once seepage starts rather than trying stop-leak products, which can create bigger cooling-system problems.
TipUse Honda Type 2 coolant or equivalent phosphate-free premix and bleed the system carefully after replacement.

Typical repair cost:$400 - $900

On the 2003-2013 Honda Pilot 3.5L V6, owners across both generations report water leaks into the cabin, commonly from clogged sunroof drains, deteriorated roof seam sealer, windshield perimeter leaks, or rear body seam leaks. Symptoms include wet headliners, damp carpets, musty odor, water in the overhead console area, and occasional electrical issues when moisture reaches connectors or modules. On older first-generation trucks, seam sealer shrinkage and body aging are frequent contributors.

This issue also affects: Chevrolet Uplander, Chrysler 300M, Chrysler LHS

Common Symptoms

wet headliner
damp front or rear carpet
musty smell
water dripping from overhead console
foggy windows
intermittent electrical issues after rain

How to Fix

Perform a controlled water test beginning at the roof, windshield, and sunroof cassette drains, then inspect headliner and pillar trim for water tracks. Clear sunroof drains with low-pressure air or flexible line, reseal failed roof/body seams with automotive seam sealer, and repair windshield or hatch-area leaks as needed. Dry the carpet and inspect under-seat and pillar connectors to prevent corrosion-related electrical faults.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipDo not use high-pressure compressed air on sunroof drains; it can disconnect the drain tube inside the pillar and make the leak worse.
TipAfter fixing the leak source, pull up the carpet padding and dry it fully because trapped moisture can linger for weeks and corrode connectors.

On the 2014-2022 Honda Pilot, honda Pilot models with white paint (Taffeta White, White Diamond Pearl, White Orchid Pearl) suffer from paint defects causing peeling, bubbling, and flaking primarily on roof and tailgate. Defect stems from problems in Honda's "three-stage" white paint application manufacturing process. Class action lawsuit filed. Honda issued warranty extension via TSB A19-055 (2014-2015 Taffeta White) covering paint to 7 years from original purchase with no mileage limit.

Common Symptoms

Paint peeling on roof or tailgate
Clear coat bubbling
Paint flaking off in sheets
White spots or discoloration
Chalky or powdery paint surface
Paint bubbles under clear coat

How to Fix

Check if vehicle covered under Honda warranty extension (TSB A19-055 for 2014-2015 Taffeta White - 7 years/no mileage limit). Visit Honda dealer for free paint repair/replacement if within extended warranty. For out-of-warranty, contact Honda corporate for goodwill repair consideration. Independent body shop repair costs $800-$2,000 depending on area. Document peeling with photos.

On the 2003-2008 Honda Pilot 3.5L V6, first-generation Pilots commonly develop worn front compliance bushings and lower control arm bushings, leading to clunking over bumps, vague steering feel, braking instability, and uneven front tire wear. This is widely reported by owners and independent shops because the heavy front end and age-related rubber deterioration accelerate bushing failure. In many cases, the bushing tears or separates enough that the arm shifts under braking or when hitting potholes.

This issue also affects: Chevrolet Uplander, Chrysler 300M, Chrysler LHS

Common Symptoms

clunking over bumps
wandering steering
uneven front tire wear
pulling during braking
front-end looseness
thump when accelerating or stopping

How to Fix

Inspect the front lower control arm rear compliance bushings for cracking, fluid leakage (if hydraulic style), or separation, and check ball joints and sway bar links at the same time. Most shops replace the complete control arm assembly rather than pressing bushings only, followed by a four-wheel alignment. If tire wear has already started, replacing worn tires after alignment may be necessary to restore ride quality.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipReplace both sides together and get an alignment immediately afterward; replacing only one worn arm often leaves the vehicle pulling or wearing tires unevenly.
TipHave the sway bar links and front struts checked at the same visit because they can create similar noises and are often worn at the same mileage.
UpgradeComplete control arm assemblies are popular because they save labor and include fresh bushings and ball joints. (Moog Front Lower Control Arm Assembly)

On the 2003-2008 Honda Pilot, a common first-generation Pilot issue is failure of the front seat belt buckle switch or related SRS wiring, which turns on the airbag warning light and can affect occupant detection logic. Honda issued service information and many owners report repeated SRS lamp illumination even when the belts latch normally. The problem is usually isolated to the buckle switch contacts or wiring in the seat area rather than the airbag module itself.

Common Symptoms

airbag light stays on
SRS warning lamp illuminated
intermittent airbag warning after moving seat
seat belt appears latched but warning remains

How to Fix

Scan the SRS system with a capable Honda-compatible tool and inspect buckle switch status data for the driver and passenger seats. Repair typically involves replacing the affected seat belt buckle assembly or repairing seat harness wiring/connectors, then clearing SRS codes. Generic code readers usually cannot access these faults, so proper SRS diagnostics are important.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipUse a Honda-capable scan tool or shop with HDS-level access; many owners wasted money replacing unrelated parts because generic scanners showed nothing.
TipMove the seat through its travel while monitoring buckle and seat wiring status to catch intermittent harness faults under the seat.

Typical repair cost:$250 - $700
