The 2019 Honda Passport shares the proven 3.5L V6 and 9-speed automatic with the Pilot, and while generally reliable, it suffers from the same transmission oil cooler failures and occasional catastrophic engine issues tied to fuel dilution in cold climates. Most units are solid daily drivers, but the severe cases can be wallet-emptying.
Transmission Oil Cooler Failure (Warped Cooler / Leaking)
Common · medium severityTypical onset: 40,000-80,000 mi
Symptoms: Transmission fluid leaking from cooler area at front of transmission, Transmission overheating warnings or limp mode, Pink/red fluid pooling under vehicle after sitting, Harsh shifts or delayed engagement when hot
Fix: Replace transmission oil cooler assembly, flush transmission. Requires dropping front subframe and disassembly of cooler lines. 4-6 hours labor depending on rust and access.
Estimated cost: $800-1,400
Fuel Dilution Leading to Engine Failure (Cold Climate)
Occasional · high severityTypical onset: 30,000-70,000 mi
Symptoms: Oil level rising on dipstick over time (smells like fuel), Rough idle or misfire codes (cylinder washdown), Metallic knocking from bottom end, Sudden catastrophic bearing failure with no warning, Check engine light with multiple misfire codes
Fix: Direct-injection engines running frequent cold short trips allow fuel to wash cylinders and dilute oil. Once bearings score, needs complete engine rebuild or replacement short block. Software update TSB 19-048 helps but doesn't eliminate risk. 18-25 hours labor for rebuild, 12-16 for short block swap.
Estimated cost: $6,500-11,000
Transmission Mount Failure (Torque Damper)
Common · low severityTypical onset: 50,000-90,000 mi
Symptoms: Clunking on acceleration or deceleration, Vibration felt through shifter or center console, Excessive driveline movement visible when revving in park, Thud when shifting from reverse to drive
Fix: Replace transmission torque damper mount (upper mount). Access from top, one of the easier mounts. 1.5-2 hours labor.
Estimated cost: $250-450
Fuel Pump Failure (In-Tank)
Occasional · high severityTypical onset: 50,000-100,000 mi
Symptoms: No start or extended crank time when hot, Stalling at idle or low speed after highway run, Sputtering under load or acceleration, Fuel pressure dropping below spec (should be 58-64 psi), May be intermittent at first, then total failure
Fix: Drop fuel tank and replace pump module assembly. Honda issued recalls for some VINs (check NHTSA database), but not all affected units were covered. 3-4 hours labor including tank removal.
Estimated cost: $600-1,200
Backup Camera Failures / Display Issues
Occasional · low severitySymptoms: Backup camera screen goes black or stays on Honda logo, Guidelines missing or flickering, Camera image freezes or displays 'no signal', Software glitch causing display reboot when shifting to reverse
Fix: Often software-related (TSB and recall coverage for some VINs). If hardware, replace camera or display unit. Software flash: 0.5 hours, camera replacement: 1-2 hours, display unit: 2-3 hours.
Estimated cost: $150-1,500
VCM (Variable Cylinder Management) Carbon Buildup
Occasional · medium severityTypical onset: 80,000-120,000 mi
Symptoms: Rough idle when VCM activates (3-cylinder mode), Hesitation or stumble during light throttle, Check engine light with misfire codes on cylinders 1, 2, or 3, Loss of power on highway merges
Fix: Direct injection causes intake valve carbon. Walnut blast cleaning of intake valves required. Some owners disable VCM with aftermarket tuner to prevent recurrence. Cleaning: 4-6 hours labor.
Estimated cost: $600-1,000
Solid SUV for warm climates or long-distance commuters, but cold-climate short-trippers should budget for premature oil changes and possible engine work—buy one with full service records and avoid high-mileage examples with unknown history.
