2024 Jeep Grand Wagoneer engine problems

Filed Nov 2, 2026 · Electrical, Engine · PA · crash

While pulling out from an intersection, at the moment I go from the brake pedal to the gas pedal, the vehicle shuts off and the screen goes completely black. During these events I also feel steering drag (heavy steering), which is consistent with a low-voltage condition. This has happened nine times so far, and I have been rear-ended in most of those events. The 12V battery voltage drops fast in auto start-stop testing (13.5 V down to about 12.1-12.3 V) and reserve capacity seems poor. This is a safety hazard because the engine can quit and power assist can be lost while crossing an intersection in traffic. I found no recall or open the federal safety agency investigation covering this stalling or the Hurricane engine in this vehicle. the federal safety agency owner complaints show about 255 on 2023-2024 Wagoneer/Grand Wagoneer models, with roughly 83 describing a stall or black dash, and at least three matching this same brake-to-gas pattern. Dealers have mostly replaced batteries and updated software with mixed results.

On four separate occasions on 10/13/26, the 2024 Jeep Grand Wagoneeer experienced sudden and complete vehicle systems shutdowns while being driven. Vehicle owner and two daughters were in the car. It was early morning (5:15am), and very dark. These incidents were not ordinary engine stalls. Suddenly and without warning the vehicle's engine shut down, all electrical power ceased, the dashboard, headlights, running lights and instrument displays went dark, and power-steering assistance was lost each time. Three of these four incidents occurred while the vehicle was traveling at approximately 15 mph, 30 mph, and 40 - 50 mph on surface streets. The worst and most dangerous incident occurred while owner was merging onto the freeway at approximately 55 mph. Because of the previous shutdowns, she had deliberately reduced speed and was traveling in the slow lane out of concern that the vehicle might fail again. Despite these precautions, the vehicle suddenly and completely shut down once more. In each of the four incidents, the owner was eventually able to restart the engine, but only after several attempts. The sudden and simultaneous loss of engine power, electrical systems, lights, instrumentation, and power-steering assistance while the vehicle was moving in the dark in traffic created an immediate and substantial risk of a serious or fatal collision. Following the fourth incident, the vehicle was towed to a Chrysler/Jeep dealer for investigation.

My 2024 Jeep Grand Wagoneer has not operated properly since I purchased it (January 2025). The most significant issues have involved engine, battery, and electrical failures, along with recurring problems related to the lighting, doors, trunk, and various cosmetic components. These issues have been repetitive. Each time the vehicle is brought to the dealer for service, repairs are often delayed for extended periods due to parts availability. Even after repairs are completed, many of the same problems recur. My experience with Jeep Corporate has also been frustrating, with slow response times and limited cooperation in resolving the underlying issues. Based on reports from other owners, these concerns do not appear to be isolated to my vehicle. I am currently awaiting a repurchase offer from Jeep Corporate. Given the repeated failures and unresolved safety concerns, I no longer have confidence in the vehicle’s reliability or in the ability to permanently correct what appear to be broader manufacturing-related issues.

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.
