There were two incidents that had similar symptoms: one before the dealership said they fixed and one afterwards. The issue is that while driving I would get three warning, all at the same time: coolant too hot, 48v battery malfunction, shut the engine off. The first time it happened immediately after I turned on the vehicle and within 5 minutes of leaving a parking lot. The second time it happened after about 3 hours of driving at highway speeds. After the first time it happened dealership said they fixed the issue by upgrading the software (battery software?). Both times it happened on the highway. The first time on the uphill, and vehicle immediately shut off and could not make it up the ramp. The second time in the tunnel on the flat road, could not make it to the exit. …

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.
