Drove to a parking lot turn the car off, the steering wheel did not lock, and when trying to start the car nothing happened. The car was dead other than door locks and a few things like the radio. Found out on YouTube how to start the car. After starting the car the steering wheel had a clicking noise as it turned right to left and it would occasionally lock. After turning the wheel left and right a couple of times I was able to steer the car. We drove the car 2 miles to our home and along the way while turning the steering wheel would lock. Repeated the same process right to left and it let me steer again. Went slowly down the road with the flashers on and managed to get it home into the garage. I would not let anyone drive a car like this totally unsafe. There are no recalls which is unbelievable since there are many many instances online of the same thing or similar happening to other people. The manufacturer should be forced to replace or repair with better quality components. I am afraid to replace these parts for fear it will just happen again as is the case with many people I read about online. I intend to disable this anyway I can so I can continue to use this car. Please step in and insist Mercedes-Benz corrects this obvious problem. I hope you can.

I was driving on I35 at the speed limit when I heard a loud pop overhead. I was not sure what it was, wondered if it was gun fire. A few days later when I got in my vehicle, and the sun was out, I was closing the sunroof cover when I noticed that the glass was shattered, pieces of glass were everwhere and began falling with the movement of the cover. It is extremely dangerous as shreds of glass are everywhere.

This is a health and safety issue regarding my car. There is mold build up in the ac system, which is a health and safety and environmental issue, this car is dangerous to the health if my family, especially to my son with asthma. Mold causes many health problems, and this car should not be driven. There is a class action lawsuit against the manufacturer but the dealer said they cant do anything about it right now to fix the problem. So our health is at risk everytime we get into the car. I can't afford to buy a new car. Getting a different car isn't an option unless this one can be bought back.

After just parking the vehicle but before getting out - the drivers headrest "exploded" and pushed my head toward the steering wheel. When driving the vehicle home the message center said problem with the driver front airbag and the passenger front airbag and the warning light was on. The next day I drove to the dealer and they pushed the headrest back together but could not get the message removed and said it would need diagnostics. I drove away with the messages still coming on intending to make an appointment for diagnostics. Returned to have the message center stop showing messages and the dealer was able to correct the issue saying it was just a blown fuse causing the problem. I drove the car approx. 30 min the next day and then 2 and 1/2 hours the following day and while driving on highway at full speed the headrest "exploded" again throwing my head to the steering wheel and I was able to narrowly avert causing an accident. I drove straight to the dealer. They pushed the headrest back in and wanted me to leave. I did not want to drive the car without someone checking the problem so they kept the car. The message center is now not indicating a problem and because the person pushed the headrest back together they are unable to see a problem. Warranty is up on the vehicle but feel this is a potential fatal safety issue to report.
