I took delivery of my 2021 GLC63 SUV a little over two months ago and several times the vehicle did not restart after the auto stop engaged. I have seen postings in other forums about this as well. When I took it to my dealer they said that this issue has been going on for the past 4 model years across many of their models. For GLEs and cars with the 48 volt system they sometimes have to remove the engine and transmission to fix the starter/48 v power assist. The GLC 63 does not have this 'feature'. It has been in the shop for a week. Apparently they have to take lots of data, send it to Germany and wait for information. Today I found out that they are doing more tests. They have found the car failed 5 times. It is bad enough that this should happen on this car, but to hear that they have not been able to fix this problem for 4 model years is pretty discouraging. Has anyone else had this problem with their GLC 63?

Wow, sorry to hear about this. My order is being built right now and this is certainly concerning to read it’s such a pervasive problem 😬
