The 2022 Honda Passport with the 3.5L V6 (J35Y6) and 9-speed automatic is generally reliable, but the engine suffers from a catastrophic design flaw: excessive fuel dilution from direct injection leads to cylinder wash and accelerated wear on rings, bearings, and cylinder walls, especially in cold climates and short-trip driving patterns.
Catastrophic Engine Failure Due to Fuel Dilution
Occasional · high severityTypical onset: 30,000-80,000 mi
Symptoms: Excessive oil consumption (1+ quart per 1,000 miles), Loud knocking or ticking from lower end at startup, Strong fuel smell from dipstick or oil fill cap, Check engine light with misfire codes (P0300-P0306), Metal shavings visible in oil during changes
Fix: Complete engine rebuild or replacement required. Involves removing engine, machining block if salvageable, new pistons, rings, bearings, head gaskets. 40-60 hours labor depending on whether heads need work. Honda extended warranty covers some cases but often denies claims citing 'lack of maintenance' despite proper oil changes.
Estimated cost: $8,000-15,000
9-Speed Automatic Transmission Judder and Shudder
Common · medium severityTypical onset: 20,000-60,000 mi
Symptoms: Vibration or shudder during light acceleration at 15-35 mph, Harsh downshifts when coming to a stop, Hesitation or delay when accelerating from a stop, Transmission hunts between gears on slight inclines
Fix: Multiple TSBs address this. Initial fix is fluid flush with Honda DW-1 and software update (2-3 hours). If that fails, torque converter replacement or full transmission overhaul. Some units have required complete replacement under warranty.
Estimated cost: $300-6,500
Transmission Oil Cooler Line Leaks
Occasional · high severityTypical onset: 40,000-90,000 mi
Symptoms: Red transmission fluid pooling under vehicle near front, Low transmission fluid warning light, Burnt smell after highway driving, Transmission slipping or delayed engagement
Fix: Replace cooler lines and seals at radiator connection points. Lines corrode from road salt and debris. Requires draining transmission, replacing lines, refilling with DW-1 fluid. 3-4 hours labor. Critical to address immediately to prevent transmission damage.
Estimated cost: $600-1,200
VTM-4 (AWD) System Overheating Warning
Occasional · medium severitySymptoms: VTM-4 warning light flashing on dashboard, Loss of AWD functionality, front-wheel drive only, Burning smell from rear differential area, Occurs during extended AWD use (snow, sand, towing)
Fix: Usually caused by rear differential fluid breakdown or clogged filter. Requires rear diff fluid flush with Honda DPSF and filter replacement. If caught early, 1.5 hours labor. If overheated severely, rear differential may need clutch pack replacement (8-10 hours).
Estimated cost: $250-3,500
Infotainment System Black Screen and Freeze
Common · low severitySymptoms: Display goes completely black, no backup camera, System freezes, touch inputs unresponsive, Bluetooth disconnects randomly, Navigation crashes or reboots mid-drive
Fix: Software bug in Honda's infotainment system. Fix requires dealer software update (1 hour). If update doesn't resolve, head unit replacement may be needed. Affects backup camera function, which is a safety concern. Recall issued for related backup camera display issues.
Estimated cost: $0-1,800
Transmission Mount Failure
Occasional · medium severityTypical onset: 50,000-100,000 mi
Symptoms: Excessive vibration at idle in Drive, Clunking when shifting from Park to Drive/Reverse, Visible engine movement when accelerating hard, Grinding or thumping over bumps
Fix: Upper transmission mount (also called torque mount) deteriorates from engine torque and oil contamination. Requires lifting engine slightly to replace mount. 2-3 hours labor. Common wear item on this platform due to V6 torque output.
Estimated cost: $400-700
Skip this year unless you get a screaming deal and extended warranty—the fuel dilution engine issue is a ticking time bomb that Honda hasn't fully addressed, and you're gambling on a $12K repair bill.
