2022 Jeep Grand Wagoneer 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 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.

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 NHTSA 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. Dates and timeframe for service: Dec 18, 2024. Returned Dec 19, 2024: Electrical work Dec 6, 2024. Returned Dec 17, 2024: Electrical work Nov 11, 2024.

This vehicle has alignment issues causing vibration at higher speeds and excessive tire wear. After multiple alignments and tire balances, nothing has resolved the issues. Dealers are not doing anything about issues. What component or system failed or malfunctioned, and is it available for inspection upon request? Our 2022 Jeep Grand Wagoneer has wheel alignment issues. We are going to our third set of tires in 56,000 miles. Vehicle has excessive vibration traveling over 75 mph after tires have been balanced. How was your safety or the safety of others put at risk? When tires have excessive wear, they do not grip the road safely and an increased danger in wet weather. Vibration at higher speeds can cause loss of control. Has the problem been reproduced or confirmed by a dealer or independent service center? Dealer just says it's out of alignment and charges 200 dollars to align vehicle, but this does not fix the issues. Dealers are no help in this issue Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only dealer and tire shops. Tire shop says it is a suspension issues, but Jeep dealer denies that Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No lights

Vehicle has a malfunctioning climate control system due to electrical / software issues. When the climate control a/c is set to manual mode it will have a "ghost" control which will randomly change settings, it changes the set temperature - recirculating mode - a/c on and off - fan speed - fan direction (windshield, face, feet) - and will also apply to the rear passenger control unit. The main and lower front climate control screens will act "crazy" when this "ghost/glitch". is happening and randomly change settings, the driver cannot override it when it is happening until the vehicle is shut off. It is extremely dangerous as this malfunctioning climate control will let the front windshield moisture build up and be impossible to clear off - which leads to a visual obstruction and could result in a crash, it's especially bad for us in the PacNW in the winter when it is dark and always wet, not being able to keep the windshield clear is scary. I've reported the issue date as 12/24/22, but it happens frequently. I have recorded videos of it happening on my iPhone but the file size is too large for here. We are still waiting for parts from Jeep to get this issue fixed, there are multiple reports from other owners on this issue also, why is this vehicle allowed to be sold to the public ? It has so many issues.

While I was driving at around 35 miles per hour and tried to stop in a short distance because of the “should I go or not” situation at the traffic light, the whole vehicle was shut off at a blink of an eye. Soon after I noticed it and tried to imitate the incident to make sure I wasn’t mistaken, it happened three time in a row. The incident can only be seen at night time when light from the headlight is visible since it happens so quick. It wasn’t just about headlight. The engine shut off and turned back momentarily as well. Thankfully each event didn’t last longer than a second and there weren’t any vehicles nearby. When I told a CDJR Monrovia service department manager about the incident and said we need to investigate, he was not serious about it. And nothing was inspected upon the request. There were no warning signs prior to the failure.

Complaint - The wiring harness in my engine compartment is mounted on the firewall below the cowl. It runs from the driver’s side to the passenger side. On my vehicle, it has a significant drop on the driver's side, almost hitting the master brake cylinder cover. The wiring harness does move significantly on the driver's side. Note-Some kinds of clips are molded onto the wire harness cover. Upon inspection of the wiring harness and cover, there is nothing that I and Service Director could find to attach the wiring harness to the firewall to keep it permanently up and away from the driver-side master cylinder brakes. Notes - My vehicle is available to you for inspection if warranted. -Dealership Service Mgr Director and Wagoneer customer service were notified and were inspected. I/we also confirmed and noted that other identical vehicles have the same problem. — inspection was performed either on the service lot by Director and myself or in the Dealership Showroom Display vehicle by me. -WCS officially informed me on 7/8/2022 that the Service Director said my vehicle wiring harness was manufactured as designed, and WCS goes by what the Director says. Because I told them (WCS) I was filling a complaint with NHTSA, they will close my case. -As of this date, no problems or failures are noted. Impression- This potential safety hazard could lead to electrical shorts, major components failure, and a possible fire hazard when the vehicle is in motion due to vibration wear, including off-road use.
