2022 MERCEDES-BENZ Gls 450 4MATIC

The car radar system apparently had a glitch and locked up the wheels while I was driving 25 mph. Yes, it is available for inspection. We are afraid to drive the car, it is just sitting. The car locked up so suddenly it made the rear wheel come off and rear of car fell to the ground. I was bruised by the seatbelt from the sudden stop. The dealer acted like they were unable to inspect it, I had the car towed there since it is under warranty. They said it had been in an accident. It had not been in an accident. I had to have policemen direct traffic until the tow truck arrived since the car was literally stopped in the middle of the street. We had an independent shop verify the issue and replace the tire and wheel that had fallen off. The car has had multiple warning messages about active brake assist inoperable, engine overheating, etc. The dealer has not been responsive at all. Seems they are trying to dodge responsibility.

I heard a very loud boom. It scared me. The sunroof exploded. I did not see anything in the road or any object flying toward me. Then I heard cracking and the sunroof started falling in above me. Thankfully, the fabric cover kept the glass from falling on me. Otherwise, the glass would have fallen on me. I could see pieces of glass. I pulled over and looked at the glass. I started towards my home and the shattered glass started flying off behind me and towards the car behind me. I did not want it to cause issues for them so I slowed down to about 30 mph so the glass would not continue to crack and fly off behind me and put on my hazard lights. My daughter called within 30 sec to a minute after it happened. She said when I clicked on the phone (through the car speaker) she heard me say a few words and the cracking of the glass. She called at 4:17 on May 24th, 2023. It was a clear sunny day. When my husband looked at the sunroof and noticed the glass coming up as opposed to caving in. So he said something did not fall through it it had to explode. We did call the dealership and they said they did not have an appointment until June 6th. My husband said we would have to clean up and take most of the glass out to be able to drive it. We did that and put cardboard over it so bugs could not get it. There was no damage to any other part of the windshield or car.

Car went into limp mode which causes loss of acceleration on major highway. This same issue of going into limp mode happened August of 2022 when the vehicle has less than 1000 miles. The car has 5750 miles and the temperature gauge showed yellow. Then the the yellow engine light came on and then the car went into limp mode where the engine loses power.

I had been driving the car for about ten minutes when the 48v battery malfunction light came on. Within seconds, another warning appeared that said coolant was too hot, and the acceleration stopped accelerating and then went to a complete stop in the middle of the road. I didn't have time to pull over. It was dark and we were completely stalled. I turned the car off, put my hazards on, and waited a minute. When I restarted the car, it worked fine and I was able to make it home. If this had happened on the interstate, I would not have had time to make it to the side of the road. The car only has 25,000 miles on it.
