Umm, help!
2021 C300 Coupe 4Matic (65,000 miles)
So, this has started happening after driving in sport mode. It happens usually after driving in sport or sport plus for a little while. I assume this shouldn’t be happening. For reference, I also wasn’t beating on it. Never approached red line and barely went over 40 mph. (I was just driving around my 25 mph town with a max speed limit of 35 and got this message.) I’m obviously planning on making a service appointment for it since it’s under a 3rd party warranty but they’re closed until Monday so I just want to get some other opinions so I have an idea what I’m in for. I presume this car should be able to handle a few accelerations while driving around town without overheating like this.
