The 2022 Grand Cherokee (WL platform) is still relatively new, but early adopters are seeing concerning engine failures on the 5.7L Hemi and a pattern of electrical gremlins tied to the Uconnect 5 system and hybrid battery management on 4xe models.
5.7L Hemi Lifter Failure and Catastrophic Engine Damage
Occasional · high severityTypical onset: 20,000-60,000 mi
Symptoms: Cold-start ticking that persists after warm-up, often cylinder 7 or 8, MDS (cylinder deactivation) misfires under light throttle, Metal shavings in oil, eventually rod knock or spun bearing
Fix: Lifter replacement requires heads-off, often finds cam lobe wear and debris damage to bearings. Many shops go straight to short block or long block replacement after teardown. 18-28 labor hours for engine rebuild, 12-16 for short block swap.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 15,000-50,000 mi
Symptoms: ATF puddle under front of vehicle, driver side, Burnt transmission smell after highway driving, Low fluid warning or erratic shifting when fluid drops below safe level
Fix: Cooler line fittings at radiator or transmission crack from vibration. Replace lines and top off fluid, inspect for overheating damage. 2-3 labor hours.
Estimated cost: $400-700
Uconnect 5 System Freeze and Black Screen
Common · low severitySymptoms: Touchscreen unresponsive or stuck on Jeep logo at startup, Backup camera fails to display, recall-related, Wireless CarPlay/Android Auto drops connection repeatedly
Fix: Software reflash via dealer StarSCAN usually resolves it temporarily; persistent cases need head unit replacement under warranty. Out-of-warranty unit swap is 1.5 hours labor.
Estimated cost: $1,200-2,000
4xe Hybrid Battery Contactors Failing to Close
Occasional · high severitySymptoms: "Service Hybrid System" warning, vehicle stuck in limp mode, No electric propulsion, runs on engine only, High-voltage battery disconnect fault codes
Fix: Hybrid battery pack contactor or BMS module replacement. Dealer-only repair due to high-voltage certification requirement. 4-6 hours labor plus battery pack R&I.
Estimated cost: $3,500-6,000
Front Upper Ball Joint Separation (Recall)
Rare · high severityTypical onset: 10,000-40,000 mi
Symptoms: Clunking over bumps from front suspension, Wandering steering or sudden pull to one side, In severe cases, complete loss of steering control
Fix: Factory recall for ball joint stud fracture. Dealer replaces upper control arms under warranty. If out of warranty, 2.5 hours per side.
Estimated cost: $800-1,400
Rear Coil Spring Fracture (Recall)
Rare · medium severitySymptoms: Sagging rear end on one side, Metallic clunk or popping from rear suspension over bumps, Visible spring fracture on inspection
Fix: Factory recall for improperly heat-treated springs. Dealer replaces both rears under warranty. Post-warranty: 2 hours labor per side.
Estimated cost: $600-1,000
The 3.6L V6 models are safer bets; avoid 2022 5.7L Hemis unless you can stomach the engine failure lottery—too many catastrophic failures under 60k miles for a two-year-old vehicle.
