2022 MERCEDES-BENZ Gle 450

My wife was driving on [XXX] going ~70mph. Without warning the engine shut down and the vehicle decelerated. A message popped up saying “48 volt malfunction”. A google search indicated the car should not be driven as it could result in a fire. Note the Mercedes dealer in Centerville Ohio completed recall campaign: 2024040002 in May, 2024. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle fails to accelerate when the accelerator is pushed all the way to the floor. Maximum acceleration is 20-25 mph. The vehicle is available for inspection upon request. My safety is greatly put at risk in normal traffic conditions due to the inability to accelerate. I am also unable to drive on the highway or anywhere requiring higher rates of speed. I am also unable to quickly remove myself from a dangerous traffic situation where acceleration is required. The dealer confirmed the problem but has been dishonest about the source of the problem and whether it has truly been repaired. First they said it was a software problem that they could not fix. Then they said it was a hardware problem. They replaced the hardware, but have never confirmed that it was not also a software problem. The vehicle has been inspected by the dealership. The engine light came on. This first appeared about 3 days before the problem started.

While driving this vehicle on the way to Los Angeles, the engine suddenly stalled without warning. I was in the left most lane going about 70MPH. The car began to slow and I almost got hit four times while trying to make my way over to the shoulder. I could've been seriously injured or killed. This vehicle is brand new and I've only had it three weeks. There was no warning indicator or lights that came on. The engine just stalled without warning and wouldn't restart. It was a miracle I made it to the side of the road as vehicles including tractor trailers whizzed by. Once on the side of the road, the vehicle would restart momentarily and the whole car would shake and then shut off. The vehicle had to be towed to a Mercedes dealer. Incredible safety risk. I don't feel comfortable driving this vehicle again. I'm going to pursue getting my money back.

While driving at highway speed, 48V system malfunction warning light illuminated, then vehicle coolant/overheat light. Vehicle lost all power, or possible entered a "limp" mode, and I was able to coast to a stop. Turned off vehicle. Checked underhood. No obvious overheating or leaks or other problems. Vehicle immediately restarted and has run fine since. This occurred in March 2022 with about 3500 miles on vehicle. Now has about 7500 miles. No further occurrence. I have not had the vehicle examined by the dealer.
