Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“It is incredibly distressing to have experienced an issue that is widely reported in this database and online forums, and remains unaddressed by MBUSA. It also seems to be an entirely preventable issue that can be fixed via a software update. The issue relates to a malfunction of the 48V battery that made the vehicle inoperatable. It happened in the midst of winter and we would be been in a dire position if our family did not come to the rescue to pick us up. The vehicle had to be towed to a dealership. …”

“2021 MB GLE 53 AMG Coupe. Less than 7500 miles. Car wont start throws a red error saying see the operators manual. This is the second time in 5 months this has happened and is extremely frustrating given MB is fully aware of the issue. They say it is related to software but I just had my car at the dealer for another issue and all software was updated. This is a design flaw that MB needs to fix before someone dies. The issue can happen at any time, I have just been lucky enough that both times it was parked in my garage. …”

“GLE53 would not start. The car threw an error stating 12v battery malfunction.(Impacted the 48V battery) This essentially disables the vehicle completely. This is 2021 GLE53 with less than 5000 miles. There is also an issue with the side-view mirror and wind noise.”

NHTSA complaint #11441783, filed 2021-11

“Purchased as a CPO directly from a local dealership. Vehicle has experienced multiple (10+), seemingly random failures of the Electronic Stability Control, Blind Spot Assist, Lane Keeping Assist and Active Break Assist under varied driving and weather conditions. On two separate occasions (one at 15+ mph and the other at 65+), these system failures were accompanied by a brief limp mode and immediate total loss of acceleration. The most recent loss-of-acceleration event occurred during lunch hour traffic on the highway, at highway speeds. …”
