The only issue we are experiencing now is the frequent “Emergency stop assist inoperative” warning.
Our vehicle is only 3 1/2 months old. This is its third time in the shop. First, for the critical low battery warning along with the “stop assist warning” - they did the recall, 2nd for the “stop assist warning” replaced a module - took 4 days, and now for the same warning. The dealer said the earliest appointment we could get with a loaner is September. We mentioned the lemon law and after the service person came back she said we could have a loaner and bring it in the next day. I see this warning has been a constant problem with mercedes vehicles since 2017, a reall was issued in 2019. One would think they could figure this out! Is anyone else experiencing this warning frequently?
i think it’s a battery issue. Returned from a week in Florida to Ny. As soon as I drove the Mercedes out of the driveway the warning appeared. Had it appear 4 or 5 times during the trip. Later in the day drove and it didn’t appear. Battery charged?
i know it appears more in stop and go traffic than on the highway. So what does our service tech do? Drives 30 miles on a highway to check it…lol!
Please offer any thoughts or suggestions.Thanks
My GLC 300 X254 is barely 3 months old. Couple of week after delivery the transmission stuck in D1. Drive home slowly in D1. Let it cool off overnight, it’s okay next morning. Send it back to the dealership, no fault code in the system they said.
in the 2nd month, “active emergency stop assist inoperative” appears on my screen once I start the car. It prevents me from shifting my gear to D or R. The road assist guy advise me to shut it down for 10 minutes and restart. Done that, the car moves but check engine indicator still light up. Send it back to the dealership. After languishing for a few days they coded the start/stop module.
on 25th April it happen again. Can’t drive out from the parking out. Unable to shift to D/R.
After 10 days, it still marooned at the dealership awaiting all clear approval from MB Germany.
Same here, GLC300e 4 weeks old... 1600km and suddendly i got all the warnings (in red) and the car stopped... Sent to service center, after 1 week they told me to pick it up. They said " Transmission needs a software update BUT is not available... MB Germany is working on it..." i got the car and after 100m it stopped again... literaly outside of the service... went inside, gave the keys and left... 8 weeks and no news... i am lucky enough because it is a company car, they provided next day GLC220d and i still get the same messages (in yellow) but if you restart everything is fine... what to say... next time i will pick the Lexus for sure... very dissapointed...
