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. With the engine off, I had no power assist for steering or braking, which made it extremely difficult to maneuver the vehicle out of the path of oncoming traffic. My family and I were nearly struck by other vehicles while attempting to get the disabled Wagoneer clear of the intersection. The recurrence of this failure at relatively low mileage (43,400 miles on a 2023 model) indicates a potential design or manufacturing defect in the cooling system, not an isolated incident. The second failure resulted in a complete loss of engine power in active traffic, creating an immediate safety hazard to my passengers and to other drivers on the road. Repair history: Failure #1: April 2024, 104 miles Failure #2: June 22, 2026, 43,400 miles Cost of most recent repair: Approximately $2,000

This complaint involves a 2023 Jeep Grand Wagoneer L Series III, a full-size luxury SUV. The vehicle has experienced repeated electrical and powertrain failures culminating in complete loss of propulsion. On 01/22/2026, while traveling approximately 45–50 mph, the vehicle abruptly shut down without warning. The engine lost power, dashboard displays went black, and multiple warning lights illuminated simultaneously. I was forced to steer to the shoulder while a trailing vehicle had to swerve off the roadway to avoid a collision. This was a near-miss event and represents a serious safety hazard involving sudden loss of motive power at highway speed. Prior to that event, the vehicle had already stalled at a traffic light and had exhibited repeated check engine warnings, low-voltage faults, and module communication errors. The servicing dealer documented multiple diagnostic trouble codes affecting the Body Control Module (BCM), Ignition System Control Module (ISCM), and Powertrain Control Module (PCM). Manufacturer technical service bulletin software updates were applied in attempts to correct the issue. Despite these interventions, the electrical instability persisted. On 02/12/2026, only days after an auxiliary battery replacement intended to address voltage concerns, the vehicle would not start and required towing to the dealership at my expense. Additional fault codes are currently under review. The vehicle is also subject to an open recall with no remedy available, and the power running board motor has failed with replacement parts unavailable. This pattern of electrical failure, sudden shutdown in motion, and inability to reliably start presents an ongoing and unacceptable safety risk to occupants and surrounding motorists. The vehicle is available for inspection and has been repeatedly evaluated by an authorized dealer.

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. Component or System: Engine and electrical system (battery and power management) Availability for Inspection: Vehicle available upon request

Vehicle speedometer has randomly blacked out on numerous occasions not allowing me to see any of my gauges. While driving on the interstate and merging the vehicle has stalled and RPMS stay stagnant yet you can hear the engine revving & then it acts like it will catch up. While driving up hill the vehicle began to stall almost like it was towing something when it was not. Back up camera has failed to turn on (resolved its self after I restarted the car). When I take it into the dealer error codes never seem to pop for these issues even though it tells me to see dealer, and read manual for proper oil and fuel usage. It’s like it has a mind of its own and it worries me to continue driving my three children around when electrical issues randomly happen every month or so & it needs constant updating. Both batteries have been replaced due to these issues draining the life out of them.

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. If the incident had happened 45 seconds prior, I'd have been still on the expressway in heavy rush hour traffic and would have been hit if my vehicle came to a dead stop or lost brake or steering control with no prior warning. The vehicle had just been serviced 2 weeks prior for thermostat failure and stalling, leaving me in an intersection. The latent defects presenting themselves on this vehicle are creating a multitude of near miss safety issues that are being minimized by Stellantis and their "customer care" representatives.

The vehicle will throw itself in the park and shut off and not restart in the middle of traffic. It's not even stopped. You can hear the parking pin trying to engage until it slows to a point and then it'll slam on and lock up the brakes and skid to a stall. This has happened four times now and the vehicle has been in the shop the entire summer. Someone is going to get killed from this.
