Jun 2, 2024 Crash

I am wanting to add information to my original complaint. Tracking#11589822 When I called in the electrical issue to AAA the agent said this is a common problem on these cars. Next, I want to add photos the Mercedes of Fresno service department sent me during the 2nd time my car was taken in to be checked. I honestly don't remember off hand when the collision occurred, I have that paper work somewhere. I will find it and send it in also. I will also get paper work from the auto body place that fixed as much of the wiring that it could. There was also a video on line I will try to find again and send that in.

According to the dealership, if the car is not started every 3 days, it will shut itself down. The car was towed 6 times, I'm a business woman, my coworkers, friends drives Mercedes Benz, and no one have heard of any such issues. Any cheaper cars, after 2 weeks at the airport, the car starts. Something is wrong with the car, something is draining the car battery if not started every 3/ 4 days. They are taking advantage to the fact, that I'm a female and older. They need to replace the car, fix, or junk their car. Someone needs to take responsibility for the repair of the car.

The sunroof on the vehicle jams and either stays partially open or won’t close in the rear completely. I finally got it to close but it will not open again. I know multiple mercedes owners who have this issue with the sunroof and if the sunroof will continue to not lock properly this could be a hazard on the highway if the brackets were to break and the glass slides off.

To Whom It May Concern, I bought this certified preowned Mercedes Benz, and the recall is open. I have taken the car to the dealership, they deny me from service because its an over the air recall. The Mercedes Benz website clearly states on their letter for consumer that the remedy for this recall can be taken care at the dealership free of charge or an over the air update. Its July and I got the car back in February.
