Filed Jul 19, 2024 · Acceleration · MN

This is a known issue with GLE 450 48v batteries over heating and causing loss of power and all function to control the vehicle. , For an unknown reason my vehicle was not part of a recent recall and probably should have been. I experienced the issue today and escaped tragedy. My battery light came on, then off, then a bright red battery light came on across the dashboard…then all of a sudden, my car lost all power with no warning. All while driving on the freeway 394! Luckily traffic was light and I was able to coast halfway up an off ramp. Then I got an overheating message. Reports show all cars were recalled, however mine wasn’t part of the recall!! I would like an investigation to include all cars in the years and models not just some of them.

Warning light "coolant too hot shut engine off" comes on repeatedly and this is unable to be fixed. Light comes on while vehicle is in motion. Was told by mercedes this was a faulty warning light. Yesterday this came on and my engine shut itself off while the vehicle was in motion on a busy street. I was almost hit by another vehicle as I lost power to the car on a main road. I barely rolled into a parking lot. Could have been a horrible (fatal) disaster had I been on the freeway. "malfunction" "see operator's manual" and "48v battery see operators manual" all came on within rapid succession before the engine shut off on me.

Driving down the highway at 70 MPH and '48v battery malfunction' warning goes off, along with a yellow check engine light. A few seconds later a 'coolant' error message pops up and a red check engine light comes on. Car looses power completely and I'm unable to accelerate at all. Call flashes a message of 'pull over and turn the engine off'. Fortunately no one was behind me and I was able to coast safely to the side of the highway before the car stalled completely. Found out through several blog posts multiple other 2020 gle owners are having the same safety issue and there has been no recall by mercedes-benz and no resolution for the issue. Vehicles are spending months in the shop and eventually being bought back by the manufacturer or dealership. This is an incredibly dangerous issue to lose all power and control of the vehicles speed. I'm lucky no one was on the road near me when this happened, otherwise an accident almost surely would have occurred. Mercedes should be forced to address this safety issue immediately.
