The 2024 Passport uses Honda's proven 3.5L V6 and 9-speed automatic, both mature platforms with known weak points. Most issues stem from the 9-speed transmission's oil cooler system and the V6's VCM (Variable Cylinder Management) causing premature wear.
VCM-Induced Engine Wear / Piston Ring Failure
Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: excessive oil consumption (1 qt per 1,000 mi), misfires on cylinders 1-3, blue smoke on cold start, fouled spark plugs, rough idle that smooths out when warm
Fix: Honda's VCM system causes uneven bore wear and collapsed piston rings on bank 1. Full fix requires engine rebuild with updated pistons/rings or short-block replacement. 18-24 labor hours for rebuild, 12-16 for short-block swap. VCM disable devices can prevent this but must be installed early.
Estimated cost: $4,500-7,500
9-Speed Transmission Oil Cooler Failure
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: transmission fluid in coolant (strawberry milkshake in overflow), erratic shifting or slipping, transmission overheating warnings, coolant loss with no visible leaks
Fix: Internal transmission oil cooler inside radiator develops cracks, cross-contaminating ATF and coolant. Requires new radiator, full transmission flush (sometimes twice), coolant system flush. If caught late, transmission rebuild needed. 4-6 hours for cooler/flush, add 16-20 for transmission work if damaged.
Estimated cost: $1,200-2,000 (cooler only), $4,000-6,500 (if trans damaged)
Transmission Mounts Premature Failure
Common · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: clunk when shifting into drive/reverse, vibration at idle in gear, excessive engine movement during acceleration, visible torn rubber on mount inspection
Fix: Upper transmission mount tears prematurely, especially on vehicles with roof racks or heavy loads. Replace both upper and lower mounts as a set — the lower will fail shortly after if only upper is done. 2.5-3.5 hours labor.
Estimated cost: $450-750
Fuel Filler Neck Check Valve Sticking
Occasional · low severity
Symptoms: fuel pump nozzle clicking off repeatedly when tank not full, slow fuel fill times (5+ minutes for full tank), fuel smell after filling, EVAP system codes P0442/P0456
Fix: Check valve in filler neck sticks closed, preventing proper venting during fill-up. This is the recall item — dealer fix is free. Independent shops replace filler neck assembly. 1.5-2 hours labor if out of warranty.
Estimated cost: $300-500 (if paying out of pocket)
9-Speed Harsh Downshifts / Shudder
Common · low severity
Typical onset: 30,000-70,000 mi
Symptoms: clunk or jerk during 3-2 or 2-1 downshift, shudder during light acceleration 20-40 mph, delayed upshifts when cold, transmission 'hunting' between gears on slight grades
Fix: 9-speed calibration issues and torque converter lockup clutch wear. Honda has multiple software updates — start there (1 hour diag/flash). If shudder persists, torque converter replacement required at 8-10 hours labor.
Install a VCM disable device (VCM Muzzler or similar) before 30,000 miles to prevent piston ring collapse — $200-400 well spent
Change transmission fluid every 30,000 miles instead of Honda's 'lifetime' claim, use genuine Honda DW-1 only
Monitor coolant overflow tank for discoloration monthly — early detection of oil cooler failure saves the transmission
Keep up with software updates at dealer — many transmission behavior complaints are calibration-related and fixed free under emissions warranty
Solid truck if you stay ahead of the VCM wear and trans cooler — buy one under 60k miles with service records or budget $2-3k for deferred maintenance, skip high-mileage examples unless engine work is documented.

Honda (American Honda Motor Co.) is recalling certain 2023-2024 Passport and 2023-2025 Pilot vehicles. The fuel filler neck tube and fuel filler pipe may separate, allowing fuel to leak.
Consequence: A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy: Dealers will inspect and repair the fuel filler neck tube and pipe as necessary, free of charge. Owner notification letters were mailed January 7, 2025. Owners may contact Honda customer service at 1-888-234-2138. Honda's number for this recall is OKM.
