The contact owns a 2022 Jeep Grand Wagoneer. The contact stated that while driving in Reverse (R), the rearview camera was inoperable. Additionally, the odometer displayed kilometers instead of miles, the radio was inoperable, and the rear HVAC system was inoperable. The vehicle was taken to a dealer, where the contact was informed that a diagnostic fee was required because the VIN was not included in a recall for the rearview camera. The failure mileage was approximately 54,000.

The contact owns a 2022 Jeep Grand Wagoneer. The contact stated that the sun visor failed to stay in place and was flopping around while driving at various speeds. The sun visor was inoperable and was a distraction to the driver. The contact stated that while making a sharp left turn at 10 MPH, the contact's vision became obstructed by the sun and the vehicle crashed into another vehicle on the opposite side of traffic. The air bags failed to deploy upon impact. The vehicle was towed to a dealer, and the front-end damage was repaired. The contact stated that the driver’s and passenger’s side third row headrests failed to remain upright and flopped backwards. The contact stated that the touch screen used to control the A/C temperature, located in both the front end and rear of the vehicle, glitched and change the temperature to an undesired level. The vehicle was taken to the dealer for repair of the screens under warranty; however, the dealer only repaired the front screen. The manufacturer was notified of the failures but offered no assistance.

I am filing this complaint because my Grand Wagoneer has experienced repeated, serious safety-related failures involving the braking system, electrical/communication systems, and vehicle shutdown. I no longer believe this vehicle is safe to operate. The most serious problem has occurred more than once. On July 21, 2026, while driving, the brakes failed. The brake pedal went to the floor and the vehicle would not stop normally. Multiple warning lights/messages appeared. I ultimately had to shift the vehicle into Park to prevent a collision. The vehicle was taken to the Jeep dealership and remained there for an extended period while the problem was investigated. The dealership reported that it could not identify stored diagnostic codes explaining the brake failure. I was told that the brake pads and rotors needed to be replaced before the matter could be escalated further. I authorized approximately $2,000 in brake-related repairs. After an extended stay at the dealership, I received the vehicle back on approximately September 1, 2026. Only approximately two days later, on September 3, 2026, another extremely serious failure occurred. While I was driving, the braking system failed again. The brake pedal went to the floor and I was unable to stop the vehicle normally. The vehicle also experienced an electrical/system failure and shut down while I was driving. Numerous warning messages appeared, including a check-engine warning and suspension/damping system failure. There was also a loss-of-communication fault involving the Body Control Module (U0140 – Lost Communication With Body Control Module). This incident occurred near my daughter’s school and created an immediate risk of a collision and serious injury. The vehicle subsequently restarted, but the clock/time in the vehicle had changed, suggesting that the vehicle may have experienced a significant electrical interruption or module reset. The check-engine light remained illuminated. Other electrical problems

The front passenger seat lumbar/massage system malfunctioned and inflated without user input to maximum capacity. The lumbar air bladder became over-pressurized and created a large, hard, immovable bulge in the center of the seatback. The system will not properly deflate and remains in this condition. The failed component appears to be the lumbar/massage module and valve system, which is electronically controlled. The vehicle is available for inspection upon request. This condition creates a rigid protrusion directly behind the occupant’s spine. In the event of a crash, this would alter occupant positioning, concentrate force on the spine, and interfere with proper restraint function and airbag performance. This will increase the risk of injury to the occupant. The problem has been confirmed by Lander’s Jeep dealership in Little Rock, AR, which acknowledged the issue but advised that diagnosis and repair would be costly and would not be covered under my warranty or extended service contract provided by MOPAR. No warning lights or messages appeared prior to the failure. The issue occurred suddenly during normal use. Online research shows countless similar failures in 2022+ Jeep Grand Wagoneer vehicles, with consistent reports of lumbar/massage module or valve failures causing uncontrolled inflation. Some owners report repeat failures and electrical issues related to the seat module. Given the repeated nature of this failure across multiple vehicles and the potential safety implications, this issue should be investigated as a possible safety defect affecting occupant protection systems. I have multiple more examples of this from Facebook Wagoneer and Grand Wagoneer Owner groups, however I am limited to just 10 uploads.

Travelling with my young daughter on the Freeway at Freeway speeds at 9pm (nighttime). The entire vehicle just shut down. EVERYTHING - completely dark. Steering went out. Brakes went out. I had to get the car to basically drift to a shoulder and slow down gradually in a spot where we would be safely out of the way of traffic. Again no brakes or steering and completely dead. Hazzard lights would not work. I had to get the car towed and get my daughter and all of our stuff out of the car on the freeway at night in the complete dark. Scary stuff. It's an expensive car and 2022 is the first model year of the Grand Wagoneer. I suspect based on my experience with this car that this model year will have these types of problems going forward. The car has had electrical issues from day 1 and its unsurprising this happened. What is surprising is just how dangerous the situation was when you were in it. It was a shocking experience.

I own a 2022 Jeep Grand Wagoneer Series III (VIN [XXX] ) that has experienced repeated, unresolved electrical system failures which pose a direct risk to my safety and to the motoring public. The vehicle has already required fourteen warranty visits, with thirty-one days out of service and twenty repeat repairs. The problems include multiple no-crank/no-start events that have left me stranded, four premature battery failures, and ongoing electrical malfunctions affecting the instrument cluster, infotainment system, HVAC, rear camera, mirrors, power running boards, and other electronic modules. These failures show that the electrical system is unstable and unpredictable. On [XXX], after the latest no-start incident, the dealership’s service manager told me directly that the issue was “more than just a bad battery.” Despite this acknowledgment, the only action taken was to replace the battery for the fourth time and declare the vehicle “repaired.” Jeep’s customer care initially agreed that the history showed a deeper safety issue and promised to open a STAR engineering inspection, but that inspection has never been scheduled. Instead, I am being pressured to pick up and drive a vehicle that the dealership itself admitted has unresolved electrical problems. This is not just a matter of inconvenience — the risk of sudden electrical shutdowns while driving, or the loss of critical safety systems such as brakes, steering modules, and cameras, presents a clear hazard to my family and others on the road. A vehicle with this history should not be returned to service based only on repeated battery swaps while the underlying defect remains unidentified. I respectfully ask the federal safety agency to investigate the 2022 Jeep Grand Wagoneer Series III for systemic electrical failures and to ensure that Stellantis does not force consumers to operate unsafe vehicles that continue to suffer from recurring electrical shutdowns.

Subject: Safety Complaint – 2022 Jeep Grand Wagoneer – Multiple Safety-Critical Failures and Warranty Concerns. I am the owner of a 2022 Jeep Grand Wagoneer (purchase price $114,000 USD), well maintained and currently with 41,000 miles. Despite careful use, it has developed multiple recurring electrical and mechanical failures that present serious safety risks: •Parking and side sensors fail, making obstacle and blind-spot detection unreliable. •Rear-view camera often shows a solid blue screen in reverse, leaving no rear visibility. •Main display flickers, freezes, or shuts off; infotainment reboots while driving, disabling controls. •Entire electronic system resets mid-drive, affecting safety features. •Power liftgate fails to open. •Air suspension changes height on its own, affecting handling and stability. While the basic 36,000-mile warranty has expired, the vehicle still has a 60,000-mile powertrain warranty. Many of these failures involve safety-critical systems that should be addressed without cost to the owner. I recently brought the vehicle to an authorized Jeep dealer, who charged $1,399 USD just for diagnostics instead of addressing them under warranty or goodwill. These issues are widely reported by other 2022 Grand Wagoneer owners, suggesting systemic defects. I respectfully request that the federal safety agency investigate promptly, require Jeep/Stellantis to issue recalls where necessary, provide a permanent fix, and ensure dealers address safety-related defects regardless of basic warranty expiration.

Our car is now having two issues: 1. The first issue is extremely scary, but we found a temporary work around so have been dealing with it for months as we needed are car. If the auto stop/start is not turned off (which has to happen ever time the car is started), the car essentially puts on an emergency break and shuts down the car at the first for second stop. This happened in the middle of a busy intersection the first time and happened numerous other times including while I was on the phone with the Jeep dealership. It is extremely dangerous as you can be stuck at a stop light in the middle of the road and the car has to be turned off and turned back on. We drive on [XXX] in michigan daily for work and it is a 55mph road with dozens of stop lights making this a huge safety hazard. I have seen numerous other people on a Jeep Wagoneer facebook page with the same issue. 2. The second issue is more recent, but has made the car un-drivable. While driving suddenly the "service fuel system" alert comes on with the check engine light flashing and the car feels like it is going to stall out, then it will regulate and the alert will go away, then it will come back a minute later. We immediately drove our car to the dealership as it was not drivable that way and they have had it for 3 weeks unable to find a fix. We put premium 93 gas in our car and it has not been in any accidents. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving the vehicle(speed does not matter as this has occurred while standing at a stop light) all safety warning lights illuminate on the dash and render all of my safety features inoperative. This includes: ABS, Forward Collision Avoidance, Rear Collision Avoidance, and Park assist. Once this happens the vehicle becomes extremely difficult to operate and to stop. The remedy is to pull over, turn the vehicle off and open the drivers side door to shut off the RAC (Retained Accessory Control), let the vehicle sit for a minute or two, then restart the vehicle. All light will remain off and the car will function normally. This issue occurs at least 2-3 times per week and is extremely frustrating. I've taken the vehicle to the dealership several times for what they have determined to be a "software issue". Several trips have been for recalls, others have been for this issue and my Infotainment system going black. The Infotainment system going black is the second major issue with this vehicle. The dealership was able to get the system operating again with an additional software update, however it has not completely remedied the problem. The Infotainment system will still black out, but for only a quick second, then it comes back on. When it does this, I loose all settings including profiles and SiriusXM programmed stations. I've done a master reset on the Infotainment system and have had it back to the dealership, but it still has not been 100% resolved. This is a safety risk when it blacks out as I loose navigation, audio, and Bluetooth connectivity. Now my attention is not on the road but on the failed system.
