What is the 2016-2022 Honda Pilot EVAP Canister Purge Valve Stuck Open (P0496/P0455) Causing Hard Start After Refueling?

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.

What is the 2009-2022 Honda Pilot VTM-4 Rear Differential Clutch Judder and Noise When Turning?

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.

What is the 2009-2020 Honda Pilot Front Blend Door (Air Mix) Actuator Failure Causing Clicking Behind Dash and No Temperature Control?

The plastic air-mix (blend door) actuator behind the dash, near the left side of the glove box, strips its internal gears over time. When it fails the vehicle loses the ability to modulate temperature (air is stuck all-hot or all-cold and cannot be blended), and a repetitive clic… Repairs typically run $150-$450. Severity: medium.

What is the 2009-2022 Honda Pilot Power Liftgate Strut and Motor Failure — Tailgate Won't Stay Open or Cycles Closed?

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.

What is the 2014-2022 Honda Pilot White Paint Peeling and Bubbling on Roof and Tailgate?

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.
