ENGINE
The thermostat failed causing the vehicle to go into a reduced power mode while climbing a hill with a trailer. The dealer has a technical service bulletin for this issue but the overheating can call engine damage or an accident when the vehicle has reduced power. There were no warnings on the cluster until the car was already in a protection mode and power had been reduced. The cluster coolant temperature gauge is slow to respond and not accurate.

SERVICE BRAKES, UNKNOWN OR OTHER
While driving the breaks faultered and I had to slam on the break. I had to press all the way down on the break pedal to slow down or stop. Also when stopped at a light the car turns off and puts itself in park. I had to turn the car off and back on again to fix it. My safety and the safety of others was at risk due to chance of a significant car crash due to faulty break system. I had a near miss accident due to this reason. I will be calling the car dealership to tow the car to have it inspected. The ABS light came on as well as check engine light. Service power steering light also came on.

SEATS
The contact owns a 2025 Jeep Grand Wagoneer. The contact stated that while the vehicle was parked, her grandson was exiting the vehicle from the second row of seats on the driver's side, he accidentally activated the fold-down feature of the seat. The seat folded over and trapped the child's head between the seat and a TV screen located on the back of the driver's seat. The contact stated that the seat stopped folding when it encountered resistance from the child's body. The contact manually pulled the seat back off the child's back. The contact stated that the child was shaken up but not hurt. The manufacturer was not informed of the failure. The failure mileage was approximately 8,000.

SEATS
This situation is similar to the recent Palisade SUV recall: The seat folding system operates when the button is pressed, even if the seat is occupied. The system does not detect the presence of a seated passenger and allows the seat to fold in both 2nd and 3rd rows. The system lacks sufficient anti-pinch protection. The motor does not stop when encountering resistance, such as a person, child, or pet, and continues folding despite obstruction. I am in the process of making the complaint with the Jeep Customer Support which directed me to Jeep local dealership to do the investigation. The inspection is not performed yet.

SEATS
- Comfort Control Module (CCM) for driver's seat and passenger seat. - Malfunction/failure of CCM caused seat lumbar/bolsters to automatically overinflate beyond maximum with no response from seat controls. - On or about 11/07/25, passenger seat back lumbar automatically overinflated beyond maximum, while passenger was seated, causing passenger to be pushed forward against seat belt. Overinflation caused seat back panel to bulge out as well. Seat would not respond to controls to deflate lumbar. Pulled vehicle over so passenger could unbuckle and seat themselves in rear seat. Immediately inspected by local dealer/service center on 11/10/25. CCM was replaced under warranty (34,453/36,000 miles) and have not experienced issue since. - On 02/17/26, driver seat back thigh bolsters automatically inflated beyond maximum while driver was seated, causing driver to shift in seat due to bolster digging into hip and thigh. Overinflation caused clip securing seat cover to cushion/frame to become detached as well. Seat would not respond to controls to deflate lumbar. Other seat controls began inflate/deflate automatically. Immediately inspected by local dealer/service center on 02/19/26 and was told module needed replacement outside of warranty (42,000/36,000 miles) to the cost of $1,573.83.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Rear climate control system fails to provide cooled air to the second and third rows during normal vehicle operation. Front vents produce cold air while rear vents blow warm to hot air despite temperature settings at minimum, high fan speed, and recirculation enabled. The condition has been present since vehicle delivery and has persisted despite three repair attempts by an authorized dealership. The problem has been reproducible under both driving and idle conditions. Independent measurements using a probe-based temperature instrument inserted into the vents confirm a significant difference between front and rear discharge temperatures. After approximately 25 minutes of driving in moderate weather (about 72°F ambient), front vents measured approximately 42–44°F while second and third row vents remained approximately 72–86°F. In warmer conditions, rear vent temperatures have exceeded 90°F. Adjusting the front climate control to a normal comfort setting causes rear temperatures to rise further even when rear controls remain set to maximum cooling. The vehicle is a three-row family SUV. The failure exposes rear passengers, including a toddler in a rear-facing car seat, to elevated temperatures during normal driving, particularly in hot and humid southern Louisiana conditions. Young toddlers are more vulnerable to heat exposure and cannot easily regulate internal body temperatures themselves, increasing safety concerns. The defect substantially limits safe and practical use of rear seating areas and remains unresolved despite repeated service attempts. No warning indicators are provided to the driver that rear cooling is inadequate. The condition reduces the vehicle’s ability to safely transport passengers in rear seating positions during hot weather. The vehicle manufacturer, Stellantis N.V., has been formally notified of the condition and is aware of the issue.

SEATS, ELECTRICAL SYSTEM, AIR BAGS
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.

ELECTRICAL SYSTEM, SEATS, UNKNOWN OR OTHER
On multiple occasions my vehicle has not recognized the key fob when I have been at the vehicle. I have actually been standing by it trying to open the door and it would not respond. Even if I was holding the key fob in my hand next to the door it would not respond. I would have to manually push the unlock button on the fob to be able to enter. This has caused me personal safety concerns when in unfavorable situations and I could not immediately gain access to the interior of my vehicle. The memor seat and easy exit functions have repeatedly failed to operate as they should causing me to be out of position when driving requiring manual resetting of the position. The heads up display consistently shows the incorrect speed limit. Google Maps and Carplay intermittently become disconnected while I am driving creating a safety hazard when I am using Google Maps guidance. The date below is simply the most recent time these happened. Again, these have happened repeatedly over the period of ownership.

SEAT BELTS, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM, SERVICE BRAKES
Late last year I reported that while towing a trailer, the dash indicated that the trailer had disconnected from the trailer as looking back I noticed the lights were off when the vehicle lights were on. Before I could pull over to check the connection, the lights turned back on and the warning light extinguished. This happened 3 times when towing the trailer that day. The dealership "reprogrammed" the module and said it was good. But after the latest recall for the Wagoneer, having it recalled, I wanted to notify someone about the potential for expanding the vehicles included in the recall.

ELECTRICAL SYSTEM, STEERING, SERVICE BRAKES
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.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
I am filing this complaint regarding my 2023 Jeep Wagoneer, which I have owned for approximately 1.5 years. Since purchasing the vehicle, I have experienced repeated and ongoing mechanical failures, primarily involving the fuel injection system and chronic battery drainage. The vehicle has been taken to the dealership for fuel‑related issues more than five times. During these visits, the fuel pump was replaced, but the problems continued. The vehicle repeatedly triggered check‑engine lights related to the fuel system. At one point, the dealership bypassed or cleared the check‑engine indicator without resolving the underlying problem. After this, the vehicle began performing noticeably differently, including a significant drop in fuel efficiency—going from approximately 18 MPG to around 14 MPG. In addition to the fuel system defects, the vehicle has had persistent battery issues. The battery drains unexpectedly and frequently dies without warning. Even after replacing the battery, the new battery lasted only about three months before the same drainage problems began again. The vehicle will randomly shut down or stop functioning correctly until another battery replacement is performed. These issues raise serious concerns about the safety, reliability, and overall drivability of the vehicle. The repeated failures of both the fuel system and electrical/battery system pose potential safety hazards while driving and have made the vehicle unreliable for normal use. I am requesting that NHTSA review these recurring problems, as they appear to indicate systemic defects affecting vehicle performance and safety.

FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
While driving, my vehicle has intermittently lost power without warning, creating a serious safety hazard. The loss of power occurs unexpectedly while the vehicle is in motion and is not associated with any driver input, weather, or road conditions.The issue has occurred on more than one occasion. The first occasion in March 2025. The issue appeared to be temporarily resolved but later recurred, indicating the underlying problem was not corrected. When the loss of power occurs, the vehicle does not respond to acceleration input and behaves as though propulsion is cut off completely. This happens suddenly and without warning while driving.This condition creates a dangerous situation, particularly when driving in traffic or at speed as was the case on 12/4/25 when driving 70 mph on the freeway, the second time the issue occurred for us. The car was immediately brought to the dealership on 12/4/2025 and remains there today. On the first occurrence the dealership attributed it to low battery charge and replaced both batteries. The dealership has performed inspections and diagnostics including:Battery testing and replacement,Wiring and harness inspections,Software updates to vehicle control modules,Extended road testing.Despite these efforts:The issue has not been permanently resolved,The dealership has stated the concern could not be duplicated,The dealership has indicated that fault codes were not always present. A STAR case has been opened, Jeep Customer Care has been contacted regarding this issue, and a field technician has been requested to come to the dealership to assess the vehicle. Despite repeated service visits I am submitting this complaint to report a recurring, intermittent loss-of-power condition that may not consistently trigger diagnostic fault codes but poses a serious safety risk for the car occupants and other drivers on the road surrounding this vehicle.
