2023 Jeep Grand Wagoneer problems

“My 2023 Jeep Grand Wagoneer has experienced recurring electrical/electronic failures since shortly after purchase on August 5, 2023. I first reported an electronic issue to Stellantis September 5, 2023. Problems began under warranty and continued despite software updates, module reprogramming, and replacement of an internally failed radio. Reported problems include: • Intermittent backup-camera failures • False obstacle detection and repeated/constant parking-sensor alarms • Service Electronic Stability Control warnings • Recurring 4WD/drivetrain warnings and problems • Transfer-case shift-motor electrical connection requiring repair • Quadra-Lift failing to consistently raise/lower correctly, delayed ride-height changes, and uneven vehicle height • Suspension/rubbing noises during turns • Repeated no-start incidents, battery failure, and jump-starts • Daily/near-daily electronic glitches, infotainment freezing, and system messages On May 27, 2026, the vehicle became completely unusable. It has remained at an authorized Jeep dealership since June 8. The dealership measured an approximately 880 mA parasitic battery draw. A Power Liftgate Module update reduced it…”

“My 2023 Jeep Grand Wagoneer, VIN [XXX], has had repeated electrical, battery, power-loss, recall, and passenger-seat safety concerns. The vehicle was serviced for ongoing battery/electrical issues and remained at South Hills Dodge for approximately one month. During that time, I was told no loaner vehicles were available, leaving me without transportation. When the vehicle was returned on XXX, the front passenger seat was no longer operable, although it worked properly before service. I returned the vehicle the same day and was told the part would be ordered. I asked if the vehicle was safe to drive because the passenger seat was making unusual noises and sounded like it could fail further. I was told it was safe to drive. On XXX, the vehicle was towed back to South Hills Dodge because it was losing power. I contacted the parts department to check on the passenger-seat part and was told no order was in the system. I was later told the part was only then being ordered, although I had previously been told it would be ordered after the XXX visit. On XXX, I received a voicemail stating the vehicle was ready for pickup and that the power-loss issue had been…”

“While starting to turn through an intersection after a red light the vehicle stalled in the center of said intersection. After turning the vehicle fully off and restarting the dash lights for a steering malfunction illuminated. The vehicle was difficult to steer but was drivable. After several on of cycles the steering was easier. We made an appointment and took it to the dealer. The dealer found the steering rack to have an "internal" fault and was unsafe to drive. The vehicle died in the center of a busy intersection. We could have been hit because the turn lest arrow ended and oncoming cars had the green light. We got the vehicle back about 9 weeks later. The steering rack had been replaced but the dealer had found corroded and charred wires to the fuel pump which also had to be repaired. The next evening with the adaptive cruise/Lane guidance set the steering system became erratic and the vehicle started trying to turn into oncoming traffic. I turned the cruise off and continued to drive about 1 mile where I was stopped at a red light. The green left turn arrow illuminated so I started through the intersection and the vehicle died in the oncoming lane. I…”

“The lumbar support in the drivers seat over inflates and balloons out past the point it should inflate and creates an uncomfortable and hazardous sitting position while driving. Ref# 11725438”

“An overheating engine causes the truck to shut down completely, block the power steering engine, and become undrivable. Electrical and harness assembly problems The dealership inspected the truck and attempted to repair it, but the same issues have recurred and are nearly causing an accident while driving on a highway.”

“Assessment of Ongoing Mechanical & Safety Issues – 2023 Jeep Grand Wagoneer To Whom It May Concern, I am providing a clear, factual assessment of the ongoing issues with my 2023 Jeep Grand Wagoneer, which I purchased for $108,000 and have owned for less than two years. During this time, I have experienced twelve separate mechanical and functional failures, several of which have rendered the vehicle undriveable for prolonged periods. Below is a summary of the major issues that continue to impact the reliability, safety, and usability of this vehicle. 1. Seat / Massage Mechanism Defect (Ongoing for Months) A malfunction in the seat massage system has created a large, hard protrusion in the driver’s seat. This defect has resulted in significant back pain, requiring both urgent care and follow-up medical evaluation. I have now been diagnosed with sciatica, which my physician has indicated is likely related to prolonged pressure and improper spinal support caused by the seat malfunction. Two dealerships have confirmed the issue and ordered the replacement part months ago, yet the part delivery has been repeatedly delayed, most recently to January 6, 2026. This has…”
