The following are issues; -Adas disables mid drive (no warning lights) at highway speeds -steering angle sensors shows not calibrated in live data feed of bscm -air ride stuck in aero mode -select terrain drive modes not functioning as intended -loses all power engine dies at stoplight and eps warning light on -
Car engine completely shuts down at highway speeds sudden loss of throttle/power at highway speed * RPM surging or erratic behavior * dashboard/light flickering * vehicle entering limp mode or shutting down * no-start condition afterward * then the vehicle “magically” works again later * dealership unable to reproduce it * sometimes no stored codes
Transmission and fuel injector malfunction: Vehicle shutters upon acceleration. Particularly noticeable driving up hill or when maintaining speeds. Vehicle is available for inspection upon request. Jeep acknowledges the issue, noted a malfunction with PICO data and a fuel injector repair was done under warranty. Stellantis deems the shuttering "acceptable." Safety is at risk as there is a hesitation and inconsistency in the transmission while driving. Yes the problem has been reproduced by 2 dealers, a Stellantis Starcase was opened and Stellantis has a SOL published for service centers but is refusing to release the fine print of the SOL to the consumer. The vehicle has not been inspected by the manufacturer despite 3 open cases requesting that a Stellantis Master Technician review the issue. Yes there were several warning lights including "Service Transmission" and "Check Engine" that began appearing at 6000 miles. The issue persists today at 14k miles.
Vehicle was driven for 5 minutes before alerting that it was overheating. While attempting to pull into a safe location off of a main road, the vehicle would not allow me to accelerate. This left our family stranded in the turn lane. I was unable to restart the engine or shift into drive.
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.
While driving my 2024 Jeep Wagoneer, the vehicle experienced a sudden and complete loss of power without warning. The engine shut off while the vehicle was in motion, including during a turn. When this occurred, I lost power steering, which made the vehicle difficult to control and created an immediate safety hazard. Prior to this incident, the vehicle had ongoing issues including overheating, repeated check engine lights, and power steering warnings. The vehicle has been taken to the dealership multiple times. A thermostat repair was previously performed, and at a later visit I was told there was an electrical/battery wiring issue that was repaired. Despite these repairs, the problem has continued. The loss of power while driving placed my safety and the safety of others at risk, especially since the failure occurred without warning and resulted in loss of steering assistance. I no longer feel the vehicle is safe to operate, particularly when transporting my children. The issue has been inspected by the dealership on multiple occasions; however, the root cause has not been permanently identified or resolved. Warning lights, including the check engine light, have appeared intermittently prior to the failure. The defect appears to be recurring and
While stopped in traffic with the brake pedal depressed and Auto Hold enabled, my 2024 Jeep Grand Wagoneer L has repeatedly jerked and shifted itself into Park without driver input. This typically occurs after being stopped approximately 20+ seconds, often while a turn signal is activated for a left or right turn. When the failure occurs, the vehicle disables driver-assist systems, the turn signals behave like emergency flashers, false rear tail light error messages appear, and the check engine light turns on and remains illuminated. The vehicle will not move until the brake pedal is applied and the transmission is manually shifted back into Drive. The issue has occurred multiple times at different locations and dates. A recent repair replaced the vehicle’s primary electronics control module(s), but the same behavior occurred again afterward. Due to the unintended shift into Park and unpredictable system behavior, the vehicle is now parked and not being driven because I do not trust it to operate safely in traffic.

The vehicle had shut down on multiple occasions but restarted. The app indicated the vehicle needed to be serviced. The key fob became inoperable; the driver was unable to lock and unlock the vehicle. There were unknown warning lights illuminated. The vehicle was taken to the local dealer, who connected the computer, but there were no codes retrieved, and was unable to duplicate the failure. The vehicle was not repaired. Additionally, the contact sent an email and videos. The manufacturer was contacted, who opened and closed several cases. The failure mileage was approximately 132.
Our car overheated because of a faulty thermostat leaving us on the side of the road stranded with kids in the car. We had to have the car towed.
Multiple battery drainage issues resulting in car not starting and battery going to zero volt. Car running hot. Failed thermostat causing engine overheat and car to shut down. System breaking issues.
The vehicle warning indicator lights Electric Power Steering (EPS) fault light comes on and the vehicle becomes hard to steer while driving. The Stop/Start active light, Engine check/ malfunction light, service power steering light comes on and the vehicle shuts down when idling at a traffic light, the engine is automatically placed into park and has to be restarted by the driver. The vehicle is back in the shop for the third time for the same issues.
n early January 2025, we purchased 2024 Jeep Wagoneer L that began displaying check engine warnings and experiencing significant performance issues within the first week. The vehicle was brought into the dealership (Golling Jeep in Bloomfield Hills, MI) on multiple occasions—first on January 22nd and again on February 7, 2025—for drivetrain-related concerns, including rough idling, and warning lights. The vehicle was returned after temporary fixes, but the issues quickly recurred. On February 21, 2025, the vehicle was returned to the dealership and has remained there ever since. Despite repeated diagnostic and repair attempts over the last five months, the dealership has been unable to resolve the issue. As of July 2, 2025, their latest communication indicates that a complete engine replacement may be required. The symptoms included drivability issues and engine malfunction indicator lights. The vehicle’s reliability deteriorated to the point where we felt unsafe using it for family transportation, especially on highways or long trips. The issue has been inspected and repeatedly confirmed by certified dealership technicians. The vehicle is available for inspection. There were no reported accidents or injuries, but the repeated and unresolved engine issues present a clear risk to occupant safety and undermine vehicle performance. This ongoing situation has rendered the vehicle inoperable for over 150 days while under warranty, with no final resolution provided.
While driving my kids to school on the freeway I received an alert telling me that my engine was overheating! I was barely given any warning of the rising temperature to allow myself to pull over safely. It never informed me it was rising, only when it was redlined near the max engine temp to which I had to immediately find a place to pull over. I didn't have enough time to get to the next exit 1 mile away, and had to pull over in an unsafe area and turn the car off until the engine cooled down while cars whizzed by us. Once cooled down enough, I was able to drive 1 mile to the next freeway exit but had to immediately pull over again into a center median as it was again overheating very quickly. My local dealership came to get the car and took my kids to school and me home while they inspected it and found a failing thermostat and water pump. I have only had the vehicle for 9 months and it only has 15,800 miles! This should not happen, at all, on a $135,000 vehicle. I also happened to notice a failing battery (no audio warning of this) on the display while scrolling through the menu looking for the engine temperature! So a brand new car has a failing battery, thermostat and heat pump..... unbelievable.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
