The 2022 Wagoneer is a full-size luxury SUV built on Stellantis's WL platform with air suspension and complex electronics. Early issues center on transmission cooler failures, air suspension malfunctions, and catastrophic engine failures on the 5.7L Hemi—notably cylinder deactivation and bearing-related problems that can grenade motors well before 100k miles.
5.7L Hemi Catastrophic Engine Failure (MDS/Lifter/Bearing)
Occasional · high severityTypical onset: 30,000-80,000 mi
Symptoms: Ticking or tapping noise from engine bay, especially on cold start, Check engine light with misfires on cylinders 1, 4, 6, or 7, Metal shavings in oil during changes, Sudden loss of oil pressure, engine seizes
Fix: Failed lifter or rocker arm from MDS (Multi-Displacement System) can drop into cylinder, destroying piston, cylinder wall, and bearings. Requires complete engine rebuild or short block replacement. 18-25 labor hours plus parts. Some shops opt for remanufactured long block swap.
Estimated cost: $8,500-15,000
Transmission Oil Cooler Line Failure
Common · high severityTypical onset: 15,000-50,000 mi
Symptoms: Transmission fluid pooling under vehicle (pink or red fluid), Transmission overheating warning on dash, Harsh shifting or slipping after extended driving, Burnt transmission fluid smell
Fix: Factory cooler lines crack at flare fittings or corrode prematurely where they route near exhaust. Coolant can also contaminate ATF if internal cooler fails. Requires cooler line replacement, sometimes full transmission flush if contamination occurred. 3-5 hours labor depending on access.
Estimated cost: $800-1,800
Air Suspension Compressor and Strut Failures
Common · medium severityTypical onset: 40,000-70,000 mi
Symptoms: Vehicle sits low on one corner, especially after sitting overnight, Air suspension fault warning on instrument cluster, Compressor runs constantly or cycles excessively, Rough ride quality, bottoming out over bumps
Fix: Air struts develop leaks at seals; compressor works overtime and burns out. Rear struts fail more often than fronts. Single strut replacement is 2-3 hours; compressor is 3-4 hours. Many owners convert to traditional coil-over setup after second failure.
Estimated cost: $1,200-2,500 per strut; $1,800-3,200 for compressor
Uconnect 5 Infotainment System Freezes and Failures
Common · low severitySymptoms: 12-inch touchscreen freezes, becomes unresponsive, Backup camera displays black screen or distorted image (recall item), Climate control unresponsive through touchscreen, System reboots randomly while driving, Apple CarPlay/Android Auto drops connection repeatedly
Fix: Software bugs in Uconnect 5 system require OTA updates or dealer reflash. Camera failures covered under recall. Persistent issues may need radio/screen module replacement—covered under warranty but expensive out-of-pocket. 2-3 hours for module replacement including calibration.
Estimated cost: $150-300 for reflash; $2,000-3,500 for module replacement
Fuel System Issues and Fuel Pump Failures
Occasional · high severityTypical onset: 25,000-60,000 mi
Symptoms: Engine stalls at idle or low speed, especially when fuel tank below 1/4, Rough idle, hesitation on acceleration, Check engine light with fuel pressure codes (P0087, P0088), Won't start after refueling
Fix: In-tank fuel pump or fuel filter housing fails prematurely. Tank must be dropped for pump replacement. Some cases involve clogged filters if vehicle sat on dealer lot with old fuel. 4-6 hours labor including tank drop and reassembly.
Estimated cost: $1,200-2,200
Rear Liftgate Struts and Power Liftgate Module Failures
Occasional · low severityTypical onset: 20,000-50,000 mi
Symptoms: Power liftgate opens slowly or won't stay open, Liftgate drops suddenly when opening manually, Error message: 'Power Liftgate Disabled', Grinding or clicking noise during operation
Fix: Gas struts wear out or power liftgate module fails. Struts are 1-hour replacement; module requires programming and is 2-3 hours. Some failures tied to water intrusion in module connector.
Estimated cost: $400-700 for struts; $800-1,400 for module
3.0L Hurricane Twin-Turbo Oil Consumption and Turbo Seals
Occasional · medium severityTypical onset: 30,000-60,000 mi
Symptoms: Burning oil smell from engine bay, Low oil warning light between changes (consuming 1+ quart per 1,000 mi), Blue smoke from exhaust on hard acceleration, Loss of boost pressure, reduced power
Fix: Turbocharger oil seals leak or PCV system clogs, causing excessive oil consumption. Requires turbo reseal or replacement. If under warranty, Stellantis covers; out-of-pocket is expensive. 8-12 hours per turbo including removal of heat shields and exhaust components.
Estimated cost: $3,500-6,000 per turbo
Skip the 2022 unless certified pre-owned with extended warranty—too many expensive catastrophic failures for a vehicle this new; wait for 2024+ model years where some teething issues were addressed.
