2022 Jeep Grand Wagoneer

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.

The contact owns a 2022 Jeep Grand Wagoneer. The contact stated that after entering the vehicle, it was discovered that the front passenger's side seat lumbar section had erroneously bulged outward making the front passenger’s seat extremely uncomfortable. Additionally, the contact stated while seated, the front passenger's head did not comfortably reach the headrest. The vehicle was taken to the local dealer, where it was determined that the front passenger’s seat lumbar module was faulty and needed to be replaced. The vehicle was repaired but the failure recurred with the front driver's side seat several months later. The front driver's side seat was not yet repaired. The manufacturer was not contacted regarding the failures. The failure mileage was 51,000.

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 NHTSA 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.
