What 45 owners told NHTSA about the 2022 Mercedes-benz Mercedes-maybach S-class

Check engine light came on few occasions. Took to the dealer and told it’s just a false alarm no problems. On the night of sept 12th 2024, I’m my way home I lost the ac cooling all of a sudden. I was only 5 mts from home. Once inside my garage I saw to my horror some smoke coming from under yhe hood. Upon opening saw some charred wires and some wire smoldering and smoke was coming out of it. Scared for my family I parked my car outside overnite and called the dealer. They had the car towed away the next day. Got my car back on 6 th of November 2024, with a laundry list of problems and issues, that they had supposedly fixed. Three or four various engine wiring harnesses were replaced, due to charring or melting, probably due to the heat. The engine and transmission were lifted off to fix all the wires and what not. I have all the invoices. And video and pictures of some wires and smoke. They don’t have an explanation for this. The recent recall about ecu maybe suggests the overheating of engine and causing the wires to burn out and some wires started burning almost causing fire if not caught in time. Called Mbusa and they didn’t show any concern. But one week after this incident they issued that ecu engine heating warning. Off course there is no repair for that. This is a fire hazard waiting to happen.

I have the 2022 S 500 with 21 inch mag spoke rims with Pirelli 255/35R21 tires on it which comes stock from Mercedes Benz. I have now been in almost 15 tires repair claims and 3 rim replacements because of how poorly Mercedes designed the rims then put a tire soon the car that cannot handle the weight of the car. I hit a pot hole and my whole tire blew out almost causing a severe crash. this is again the almost 15th time this has happened. I took the car to Mercedes Beverly Hills and the service advisors say that now there is $16,000 dollars in damages on the car fro the constant impact it has taken from the rims being poorly designed on the car. I have asked many times to replace the tire brand to a better and thicker tire. but Mercedes will not allow that and demands I pay over 16k in damages to fix suspensions and the drive unit issues.
