2022 Jeep Grand Wagoneer

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

My 2022 Jeep Grand Wagoneer has been subject to an open safety recall involving the rear passenger-side window trim since I purchased the vehicle in 2025. I scheduled and attended numerous appointments with the authorized Jeep dealership seeking completion of the recall repair, but the defect was never remedied. On September 7, 2026, my husband was driving the Grand Wagoneer while I followed behind in another vehicle. My two toddlers were occupants of my vehicle. Before the incident, I observed the recalled rear passenger window trim flapping and becoming loose. The trim then detached completely from the Grand Wagoneer while both vehicles were traveling at approximately 75 mph on the highway. The detached trim entered or moved toward my vehicle’s path, forcing me to swerve suddenly to avoid striking it. This created an immediate risk of losing control, colliding with another vehicle, or leaving the roadway. The incident endangered the occupants of both vehicles, including my two young children, as well as other motorists. Fortunately, no collision or injuries occurred. The flapping trim was the only warning immediately before it detached. The dealership had prior notice of the unrepaired recall because I had brought the vehicle in approximately four times beginning in November 2025. Despite those appointments, the recalled component remained on the vehicle and ultimately failed in the manner the recall was intended to prevent. The vehicle and photographs of the affected area are available for inspection. The detached trim was recovered. Dealership service records and recall communications documenting the unsuccessful repair attempts are also available.

There have been multiple recalls (77C and 88C) affecting 2022-2025 Wagoneers where the trimming was not properly secured at the vehicle assembly plant. Our rear window trim was affected by one of these recalls and has fully detached from our vehicle while we were driving which has yet to be replaced by the dealership. I have attached a picture to show our rear window trim that is missing. We are having a similar issue with our front passenger window trim but the dealership has stated this is not part of the recall but based off the pictures attached it is evident that the retainer clips were also not fully engaged in this part of the window trim and is beginning to detach and pose as a road hazard if it completely detaches from the vehicle while driving.

There were 2 recent safety recalls (77C and 88C) that affected numerous 2022-2025 Grand Wagoneer vehicles regarding the window trim. One of the recalls directly affected our vehicle where the rear trim detached and flew off our vehicle. The dealership has yet to replace this rear trim stating that the window has to be replaced as well and is currently on backorder. The bottom half of our window trim on the passenger side is also starting to detach from the vehicle but the dealership states that it is not part of the recalls associated with our vehicle. It is a similar issue where the trim was not properly secured. The retainer clips are clearly not fully engaged which can be seen in the attached photos. I have also included a photo of our rear trim to show how it has completely detached from our vehicle so clearly an issue at the vehicle assembly plant with our vehicle. If this bottom half of our passenger window trim detaches while driving it will pose a road hazard to operators and occupants of other vehicles.

I am submitting additional information regarding NHTSA complaint #11725438 involving my 2022 Jeep Grand Wagoneer Series III. The original complaint involved the front passenger seat lumbar support unexpectedly inflating to maximum firmness without any occupant input. The lumbar support became extremely hard and uncomfortable as though it had inflated to its highest setting on its own creating a large rock hard bulge in the passenger’s back. Since filing the original complaint, the same defect has now occurred in the driver’s seat. The driver’s lumbar support suddenly became rock hard without any adjustment being made to the seat controls. The change was sudden rather than gradual happening overnight. This defect has now occurred in both front seats of the vehicle, suggesting a possible system-wide issue rather than an isolated seat component failure. The unexpected inflation creates a driver distraction and can affect comfort and vehicle operation while driving. This complaint is intended to supplement and update NHTSA complaint #11725438. I request that this additional occurrence be added to the existing record. Many other Wagoneer owners have experienced this same issue as I see repeated complaints of this happening on the Wagoneer and Grand Wagoneer owner’s facebook pages. There is no way to remedy this situation on my own. The vehicle is not just uncomfortable, it is unsafe in this condition.

The contact owns a 2022 Jeep Grand Wagoneer. The contact stated that while driving at an undisclosed speed, the front passenger seat had inflated without a passenger seated in the seat. No warning light was illuminated. The front passenger seat failed to deflate. The vehicle was taken to the dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure and advised the contact to report the failure to the NHTSA Hotline. The failure mileage was approximately 80,500.

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.

The contact owns a 2022 Jeep Grand Wagoneer. The contact stated that while driving at approximately 50 MPH, the ABS, the ESC, and the Parking Brake warnings illuminated. The contact stated that the brake pedal felt loose and travelled to the floorboard upon depression; however, the vehicle failed to respond. The contact shifted to neutral (N), and the vehicle decelerated. The contact stated that she was picked up by her husband, who then drove the vehicle to a dealer. The vehicle had not yet been diagnosed or repaired. The contact stated that the same failure had previously occurred while reversing (R) out of the driveway. The manufacturer was not informed of the failure. The failure mileage was approximately 61,000.
