Electrical System Shorts and Wiring Failures
The Grand Wagoneer's extensive electronics suite suffers from wiring shorts, failed error messages, malfunctioning keyfobs, and random loss of power. Forward collision avoidance system malfunctions are among the most frequently reported complaints. The vehicle may display multiple simultaneous warning lights unrelated to any actual fault.
Perform a full electrical system diagnostic scan to identify shorted circuits. TSB 08-080-22 covers wiring harness inspection procedures. Replace damaged wiring harness sections and update BCM software. Keyfob reprogramming or replacement as needed.
Est. Cost: $200 - $1,500eTorque 5.7L V8 Stalling and Power Loss
The 5.7L eTorque engine stalls unexpectedly while driving, causing loss of power steering and braking. The 48V mild hybrid system may engage the parking brake automatically during a stall, creating a dangerous situation at highway speeds. This issue is under NHTSA Preliminary Evaluation PE24018.
Update the PCM and eTorque control module software. TSB 14-010-22 addresses eTorque system communication faults. Replace the 48V battery if it cannot maintain charge. The MGU may need replacement if a whining noise is present.
Est. Cost: $500 - $3,000Uconnect 5 Display Failures and Screen Artifacts
The premium McIntosh-equipped infotainment system experiences random screen reboots, static lines across the display, partially blank screens, and complete touchscreen unresponsiveness. The navigation system loses stored destinations and waypoints. Multiple owners have required full display module replacements.
Update Uconnect software to the latest firmware version. TSB 08-062-22 covers display module diagnostics. Replace the display module if hardware artifacts persist after software updates. Inspect the display wiring harness connection behind the dash panel.
Est. Cost: $0 - $2,500Third-Row Seat Belt Access Issues
The third-row seat belts may not allow occupants to properly access or fasten the seat belt to the buckle, failing to comply with Federal Motor Vehicle Safety Standards. The buckle position or belt routing makes it physically difficult for passengers to buckle in, especially children in car seats.
NHTSA Recall 22V-861 requires dealer inspection and modification of the third-row seat belt assembly to ensure proper buckle access. The repair involves repositioning or replacing seat belt anchor points.
Est. Cost: Covered under recallSteering and Brake Complaints
Owners report a vague or numb steering feel on-center, excessive steering wheel play, and inconsistent brake pedal response. The steering may feel overly assisted at highway speeds and then suddenly firm up. Brake noise (grinding or squealing) from the front brakes has been reported at low mileage.
Reprogram the Electric Power Steering module for improved on-center feel per TSB 19-010-22. Machine or replace front brake rotors and replace pads with updated Mopar compound if noise is present. Bleed the brake system if pedal feel is inconsistent.
Est. Cost: $200 - $900
