2024 Jeep Grand WagoneerRecalls, problems, MPG & safety

“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 NHTSA investigation covering this stalling or the Hurricane engine in this vehicle. NHTSA 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…”

“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.”
