BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Honda (American Honda Motor Co.) is recalling certain 2018-2020 Odyssey, 2019-2020 Passport, and 2019-2021 Pilot vehicles. Incorrect instrument panel control module software can cause the instrument panel to not display critical information, such as engine oil pressure, speedometer, and gear selector position until the next ignition cycle. Additionally, it can prevent the rearview camera image from displaying. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Control and Displays" and 111, "Rearview Mirrors."
ELECTRICAL SYSTEM:SOFTWARE
Honda (American Honda Motor Co.) is recalling certain 2019-2021 Pilot, 2019-2020 Odyssey and 2019-2020 Passport vehicles. Incorrect central network software programming may cause several errors to occur that can delay or prevent the rearview camera image from displaying. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rearview Mirrors."
TIRES
Honda (American Honda Motor Co.) is recalling certain 2019-2020 Passport and Pilot vehicles equipped with Continental tires. On the affected vehicles, it is possible that one or more tires were cured for too long during tire production.
EQUIPMENT:OTHER:LABELS
Honda (American Honda Motor Co.) is recalling certain 2020 Passport and Pilot vehicles. The certification label may have been printed with ink that can be wiped away with a solvent, removing the Gross Axle Weight Rating (GAWR) and Gross Vehicle Weight Rating (GVWR) information.
STRUCTURE:BODY
Honda (American Honda Motor Co.) is recalling certain 2019-2020 Pilot and 2019 Passport vehicles. The front frame left and right side upper members may not have been welded completely to the unibody. As such, these vehicles may fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 208, "Occupant Crash Protection" and 219, "Windshield Zone Intrusion."

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 converter… Severity: high.
Brake master cylinder may have been improperly fastened to brake booster during production, resulting in loose or missing tie rod nuts. Tie-rod studs may break due to bending load when brake pedal pushed, causing master cylinder to separate from booster and loss of braking abilit… Severity: high.
3.5L V6 uses timing belt (not chain) that must be replaced every 105,000 miles or 7 years. Timing belt failure causes catastrophic engine damage (bent valves, damaged pistons) costing $3,000-$6,000. Water pump is driven by timing belt and should be replaced simultaneously since l… Severity: high.
Pilots equipped with Honda Sensing exhibit 'phantom braking,' where the Collision Mitigation Braking System applies sudden, hard, unexpected braking when no obstacle is present. Owners report it triggering on overpasses, near oncoming traffic, over bridge shadows, or on open high… Repairs typically run $0-$600. Severity: high.
Center console touchscreen goes completely black or becomes unresponsive. Audio/navigation system may enter infinite loop during shutdown that drains battery. Loose fuse connections in 2016 models and software glitches across all years are common. Class action lawsuit includes 20… Severity: medium.
Honda Pilots experience excessive parasitic battery drain (over 80mA) causing dead batteries after 24-48 hours. Common causes include radio/audio staying active when off, Bluetooth module constantly searching, and AC compressor clutch relay sticking on. Normal draw should be 12-3… Severity: medium.
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 conditi… Severity: medium.
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). Lo… Severity: medium.
AWD Honda Pilots experience rear differential fluid leaks from temperature/pressure sensors, axle seals, and case deterioration. Loose or damaged fluid pressure sensors drip onto axle seals. Some cases involve holes in differential case with extensive aluminum deterioration. Leak… Severity: medium.
The backup camera fails to display a live image, showing a black, flickering, or lined screen when reverse is selected. On 2009-2015 Pilots the common cause is water/condensation intrusion into the tailgate-mounted camera housing that corrodes the unit; on 2019-2022 Pilots (and 2… Repairs typically run $200-$700. Severity: medium.
AWD Pilots use Honda's VTM-4 rear differential, whose internal hydraulic clutch packs make a shudder/judder and noise during low-speed tight turns (e.g., parking lots, U-turns) when the VTM-4 differential fluid degrades or becomes contaminated by clutch-friction particles and/or… Repairs typically run $65-$150. Severity: medium.
On power-liftgate Pilots the gas-charged support struts weaken and lose nitrogen pressure prematurely, so they no longer help lift or hold the heavy tailgate. This forces the power motor to carry the full load, which leads to the liftgate opening then immediately closing, grindin… Repairs typically run $60-$800. Severity: medium.
The EVAP canister purge valve sticks open and allows fuel vapors to flow into the intake when they shouldn't. On 3rd-gen Pilots this commonly sets P0496 (EVAP high/incorrect purge flow), and can accompany P0455/P0441; drivers notice a check engine light, rough idle, and pronounce… Repairs typically run $30-$250. Severity: medium.
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… Severity: low.
The driver and passenger sun visors lose the ability to stay in the raised position and droop down into the driver's line of sight, often within a few years of ownership. The failure is the internal pivot mechanism: the leaf spring that rests in a detent on the hinge rod, or the… Repairs typically run $30-$150. Severity: low.
