2024 Jeep Grand Wagoneer electrical 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.

When sitting at the light my vehicle completely shut off. When I was able to restart the vehicle the power steering light came on. After driving for a few moments, the vehicle did the same thing and steering concerns continued. The vehicle was on two major roads with other vehicles around. This put myself, my son, and other drivers on the road in danger of being involved in an accident. The vehicle was taken to the dealership under the Florida Lemon Law. The aux and main battery were replaced. The representative from Stellantis denied our Lemon Law request of repurchase or replacement of this vehicle. By Jun 2026, under one year of ownership, the vehicle had already spent over 38 days at the dealership for service related issues: airbag issue, steering related failure issue, steering rack replacement, battery replacement, and now on July 9,2026 the vehicle attempted to shift into Park, the electronic parking brake engaged, and the vehicle became immobile while we were actively driving. This produced another safety concern for our family and other drivers on the road. The vehicle is currently with the dealership attempting to diagnosis this defect.

On June 18, 2026, I was driving my 2024 Grand Wagoneer on a busy city road. As I approached a busy intersection, I stopped at the red light. When I attempted to move forward when the light turned green, it moved a few feet (putting us in the middle of the intersection), the vehicle seized and became immobile. Almost every light on the dashboard lit up. Several messages flashed back and forth on the screen including "Service transmission" and then "service electronic stability control". I immediately tried to use the SOS function, and when they answered, they were unable to hear me. A person in a truck behind me told me to put my vehicle in Neutral so that the vehicle could move out of the road as it was blocking traffic. When I tried to turn the gear dial, it turned, but the P light stayed on and the vehicle would not go into Neutral. I checked the parking brake and it was not on, nor would it engage. The vehicle being stalled, with zero ability to move put my children and I in danger as there was not a safe place to even exit the vehicle as traffic was completely surrounding us. I tried to turn off the vehicle, but the vehicle stayed in the "run" function even after being pressed. Emergency services was my only next choice. One more push of the off button and the vehicle finally turned off. I waited for 2 minutes and tried to turn the vehicle on again. It did turn on, showing the check engine light. I then was able to put the car into gear, and it moved. I moved the vehicle out of traffic to the next available parking lot. I immediately contacted the dealership and told them I would be having the vehicle towed there for inspection and I do not feel comfortable driving this vehicle again. Unfortunately, this is the 3rd time my car has put me in a dangerous situation in the middle of an intersection, the other 2 being false crash alerts (turning left in turning lane and car thought I was going into oncoming traffic).

This issue has happened three times. I am on the highway going 70mph, the RPMs fluctuate, the headlights go out and then I lose propulsion/unable to maintain or increase speed. This is a safety concern as it has happened 3 times on the highway with no warning and limited time to pull over to safety. The dealership is unable to replicate the problem or diagnose an issue.

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.
