No recent work or changes That's baffling It just started happening Was your issue also related to a faulty control unit, and was a software reset all it needed

Mine was a software glitch in the control module. They tried a software reset first, but it didn't completely fix it. They ended up having to re-flash the entire control unit. I'd recommend taking it to a workshop with experience in Mercedes onboard diagnostics. They'll be able to pinpoint the issue and re-program the control unit if necessary.

That's exactly the kind of info I was hoping for. Knowing that a simple reset might not cut it is super helpful. I'll definitely take it to a reputable workshop and mention the possibility of re-flashing the control unit. Just got it back from the workshop. They confirmed it was indeed a software malfunction and re-flashed the control unit. Everything seems to be working perfectly now Thanks again

I think I had a similar issue with my GLE, although I can't remember the exact error codes. The navigation went haywire and the electrical system was acting strangely. Did you recently have any work done on the car, or any software changes?
