2023 Jeep Grand Wagoneer driver assistance problems

Filed Sep 30, 2026 · Driver assistance, Electrical · SC

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 to 350 mA. Further diagnosis identified a LIN-bus fault, water in the left rear taillight, and connector corrosion. Isolating that area reportedly reduced the draw to 17–20 mA. After months of OEM-part backorder, the dealership fabricated and installed a harness/connector and reports the draw is resolved. I did not authorize this as a permanent solution. Stellantis stated in writing that a workaround outside the warrantable repair process would be temporary and not covered under warranty. Repair records do not capture the full extent or frequency of reported intermittent/recurring failures. I request the federal safety agency review the electrical, camera/sensor, stability-control/4WD, and suspension failures for potential safety defects.

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 had to turn the vehicle totally off and restart it in order to proceed. Once moving there were 2 steering system warning lights illuminated on the dash. I cautiously returned home then made an appointment to return the vehicle to the dealer. The warning lights went out but the dealer found multiple codes in the ECU. They had the vehicle for a while, said they reprogrammed the modules that control the steering after which the symptoms could not be duplicated. We have the vehicle and several issues still persist. I called today for another service appointment. The vehicle has an odd steering twitch in tight turns especially in parking lots or driveways. Steering effort is noticeably higher and doesn't return to on center position without input. The steering wheel is not centered during straight driving.

I am writing to formally document a serious and extremely concerning safety incident that occurred on Wednesday, March 4, 2026 at approximately 12:06 PM while driving my 2024 Jeep Wagoneer, which currently has approximately 58,000 miles. While driving, multiple critical warning lights and system failure messages appeared simultaneously. I have attached photos documenting the warnings that occurred during the incident. Service Power Steering • ABS warning • Red steering wheel with exclamation mark • Check Engine Light • Collision / Auto Emergency Braking warning • Traction Control / Electronic Stability Control Warning • Forward Collision Warning / Automatic Emergency Braking Disabled During this event, the vehicle behavior became unpredictable and unsafe. Considering the failure of multiple safety systems at once, this created a situation that could have easily resulted in a serious accident. I am extremely shaken by the experience and thankful that my four children were not in the vehicle with me at the time. Unfortunately, this incident is part of a long list of issues I have experienced with this vehicle since purchasing it. These include: Persistent check engine light issues • Replacement of all third-row seatbelts due to defects • Oil valve replacement (Code P06D – Oil Pump Control Stuck High) • Multiple software updates • The vehicle shifting itself into park when coming to a stop, with the gear dial locking and requiring the vehicle to be fully shut off and restarted before it can be driven again • Driver window intermittently sticking • Replacement of the passenger seat massage system due to an air bladder malfunction • Vehicle jolting/jumping when coming to a stop Given the number of ongoing mechanical and electronic problems, I no longer feel confident that this vehicle is safe to drive. I purchased this vehicle specifically for the safety and reliability.

Blindspot indicator keeps turning on and off, distracting the driver. Have taken vehicle to dealer many times they say it can’t be fixed even though it was during Warranty. They say a jeep is aware, but no plan to fix.

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 affected my ability to safely and comfortably operate the vehicle, and has now escalated into a documented medical issue. 2. Suspension Noise During Auto-Leveling The vehicle’s air suspension system produces extremely loud noises during auto-adjustments. This raises concerns regarding the safety and structural integrity of the suspension system. 3. Window Hinge Failure A window hinge has prematurely failed, requiring service intervention. This is not consistent with typical wear for a vehicle less than two years old. 4. Cruise Control Malfunction The cruise control system intermittently ceases functioning while driving. The only way to restore it is to turn the vehicle off and restart it, which presents a safety concern when traveling at highway speeds. This points to a possible electrical or

AEB system engaged emergency braking for no apparent reason when traveling at >35mph on a busy road with the flow of traffic. My face actually hit the steering wheel and a car traveling behind me barely stopped in time to avoid rear ending me. The AEB system has repeatedly displayed warning lights in the dash previously. For each occurrence, the vehicle was serviced at the dealership and reassurances were provided each time that the underlying issue was remedied with reprogramming and/or replacement of electrical control modules, however the recurrent nature of the issue (and many other issues surrounding the electrical system in my Grand Wagoneer) doesn't instill confidence in the "fix" they're providing. At this point in time, I don't feel safe driving my Grand Wagoneer, as I don't know when the vehicle will involuntarily slam on the brakes in traffic and cause an accident.

While driving my 2023 Grand Wagoneer the Serv 4WD light and dash spelled out Service four wheel drive, it lit up the anti collision light, ECS, TCS, and HOLD!. The parking brake also engaged automatically while driving at least 4 times. This is a serious safety concern to allow a vehicle to continue driving with the ability to automatically engage the parking brake while driving. The safety of my entire family was put at risk. I currently have the vehicle sitting at the dealership to be diagnosed and reproduced as the vehicle lost all power after this incident. Another serious safety concern is the total loss of power with no notice. This could easily have been while I was driving and caused a serious accident and possible fatalities.

We the dealership technician had the vehicle for a repair, he was driving it back-and-forth to work like he owned the car and one day He was leaving his home to go to work and the suspension failed so that had to be fixed and that was back on one of the many time it was in the shop. The stop/start engine doesn’t engage for me when I break for me. For me to get it to engage I have to slam on the break as if I was bracing for an accident and then the stop/star engine mode will engage. I think this vehicle has had five clusters replaced in the car, due to the parking sensors, side warning sensors not working. I believe the fifth one went in Dec 2024 once again. The vehicle was in the shop from November 22, 2024 until yesterday DecemberI 2, 2024 when I picked it up. I got home and the parking sensors didn’t beep off and I could’ve crashed it into my garage door and I went through the system and it was already selected to beep but didn’t, then I started getting a message saying that the side warning sensors are unavailable. I put it in reverse it tells me the wipers are off, so maybe all the clusters that they’re making are faulty. The Jeep Retention Customer Service even sent a specialist, technician assistant to the dealership twice or three times to deal with this issue and it’s still not fixed. The dealership Service Center has put in request for answers of how to fix these problems and have had to wait weeks for answers because they don’t know the answers of how to fix the problems with these vehicles and they send a specialist and still the problems still occur they say put in a new cluster a new cluster gets put in the problem still happens. The part is shipped directly from a manufacturer and they have no ETA on that part and my car would still be in the shop, but the Jeep Retention Customer Service Rep had it expedited but the problem is still ongoing. THERE NEEDS TO BE A RECALL ON THIS CAR AND PEOPLE SHOULD GET THEIR MONEY BACK
