Owner reports
Selected complaints filed with NHTSA by 2023 Jeep Wagoneer owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2023 Jeep Wagoneer. The contact stated that while driving at various speeds, the parking brake was independently engaged. Additionally, the front driver's and rear passenger's side windows would independently lower while driving. The contact stated that the vehicle would jerk while depressing the accelerator pedal, with the check engine warning light illuminated. The contact would restart the vehicle after each failure to resume normal operation. The vehicle was then taken to the dealer where the vehicle was serviced. Despite the initial repair, the parking brake and jerking persisted with the check engine warning light illuminated after each repair. After one visit, the check engine warning light returned soon after exiting the dealer parking lot and the vehicle was towed back to the dealer for service. …

There was an abnormal horn sound detected. The contact stated that the engine overheated and the vehicle stalled. The vehicle was jump-started. The contact was locked out on several occasions.

I bought this vehicle used form Carmax, <12000 miles. Drove about 12 miles, when while parking I noticed the car stopped and asked to start engine and engage gear again. Didn't think much of it. Then started driving again and the check engine light turned on. There are lots of reports of wagoneers with engine light problems (in fact we had test driven a different one with both check engine and transmission lights on which for obvious reasons didn't buy). I reported to Carmax. Finished my drive and stayed idle for a while trying to see if there were any settings that may be responsible, but the engine was stuttering, almost shutting off, with the entire thing, even the driving lights shutting off intermittently. The following day I took the vehicle for a check at Carmax, and while slowing at an intersection to let a school bus pass, the car completely shut down. …
The component that failed was the thermostat. This failure caused my engine temperature to spike abruptly as I was driving. My safety and my children's safety were put at risk by creating no engine power, undriveable, and was almost hit by cars due to sudden slow down to decrease engine temperature to prevent from over heating. The problem is being reproduced by Five Star Dodge dealership in Milledgeville, GA and being inspected by their mechanics. There were no warning lamps, messages or other symptoms whatsoever of the problem prior to failure. The failure was immediate which again put my children and I in harms way. This recall is reported on thousands of other 2022-2023 Jeep Wagoneers yet no recall on my vehicle. That recall needs to expand to probably thousands more Wagoneers that are experiencing this failure. …
Immediately after getting off of the expressway on the drive to work, there is a stop light at the intersection of city streets. While sitting at the stop light, foot on the brake, the vehicle stopped running, the brake pedal went to the floor, and the Service Power Steering warning screen was flashing and chiming. I immediately put my hazard lights on to warn oncoming traffic that I wouldn't be proceeding, because at that point the light changed to green and people behind me were letting off their brakes and rolling forward. After about 45 seconds to 1 minute, the vehicle showed a screen that said to place foot on brake and press ignition to start the vehicle. I was able to start the vehicle again, but the power steering warning light was still on. I had the vehicle towed from the street parking near my job. …
The contact owns a 2023 Jeep Wagoneer. The contact stated that on several occasions, while driving at various speeds and continuing to accelerate, the RPM failed to respond as needed. Additionally, while slowing down the RPM failed to lower. The contact stated that the check engine warning light illuminated, or the message to check the user manual for proper oil and fuel usage was displayed. The vehicle was taken to a dealer, where it was diagnosed, and determined that a system update was needed. The vehicle was repaired, but the failure reoccurred within several months. Additionally, the contact stated that while driving on several occasions at various speeds, the entire instrument cluster became inoperable, with the speedometer remaining at 0 MPH, or the message to "Depress Brake Pedal to Start Vehicle" was displayed. …
Vehicle: 2023 Jeep Wagoneer Mileage at time of incident: 43,400 miles Component: Engine Cooling System / Thermostat Incident Description: This vehicle has experienced two separate thermostat failures since purchase. The first failure occurred the day after I purchased the vehicle, in April 2024, at only 104 miles. This time the vehicle overheated /stall pattern even after confirming coolant was at a sufficient level. The second failure occurred on Monday, June 22, 2026, at 43,400 miles. While driving with my wife, son, and son's friend as passengers, the temperature warning indicator activated, signaling an engine overheating condition. Shortly after, the engine lost power and stalled completely while the vehicle was in the middle of a busy intersection. …
I purchased my 2023 Jeep Wagoneer new in March 2023. The vehicle has experienced multiple electrical/electronic safety-related failures. Beginning around Oct. 2024, the digital instrument cluster intermittently failed to load after startup, leaving me without critical information including vehicle speed and fuel level. I photographed this occurring numerous times and repeatedly reported it to the dealer. The cluster was eventually replaced in April 2026. The vehicle has also unexpectedly shut off more than once while slowing or coming to a stop at a stop sign or traffic light. In July 2026, the entire right-front exterior lighting system failed. The right headlight, daytime/running light, front turn signal and cornering light are all inoperative while the left side operates normally. The dealer replaced the complete right headlamp assembly in Aug. …
For the past five months, the vehicle has stalled nearly every other day, including while backing out of driveways or parking spaces and when slowing to stop. Each time, the engine suddenly shuts off without warning, the transmission automatically shifts into Park, and the emergency brake engages. An engine warning light appears with a "battery fault" message. The repeated engine shutdowns and automatic braking create a serious safety risk, particularly when backing into traffic or stopping at intersections. In several instances, the vehicle would not restart for several minutes, leaving it disabled in the roadway. The vehicle has been taken twice to the authorized Jeep dealership in Stonecrest, Georgia, but the service department was unable to reproduce or correct the issue. The problem persists, and the "battery fault" light continues to appear intermittently. …
