On May 10th while driving on I-35 Texas highway, San Antonio Texas, the panoramic sunroof of our 2015 Mercedes Benz CLA 250 completely shattered while wife driving and daughter as a passenger, they heard a big bang and suddenly pieces of shattered glass fell all over the interior some of the glass hitting my wife and daughter in the face, they immediately pulled over to evaluate the situation. This could have caused an accident or significant injury. She had SAPD meet her at a gas station as she thought someone has shot at the glass, but officer confirmed that indeed the panoramic sunroof completely shattered. We tried to fix the panoramic roof and both Mercedes dealerships in San Antonio and Boerne Texas refused to repair the panoramic sunroof, we had to file a claim with our insurance and take the car to a collision center. The collision center stated that the sunroof was on back order from Mercedes Corp and had no timeline as to when the part would be available. Due to the car was not safe to drive and timeline on the parts, our insurance offered to total the car, but the car is almost new, low miles and in perfect mechanical condition so we declined. We received a call 4 months later that the car was fixed and the panoramic roof was installed.

I noticed for the last several weeks my car sometimes hesitates when I start the engine. I hadn't looked into it and wasn't sure what it could be because I changed my battery less than 2 years ago. I hoped it was a fluke or do to the increasing cold weather. Also the car occasionally shudders and hesitates when I increase and decrease speed and one or two the radio shut off on it's own. This morning, the automatic windshield wipers came on even though it was not raining and my windshield was not wet. This lasted for a few minutes before it stopped on it own. Then I drove about a mile and was at a stop light. When I eventually tried to accelerate, I wasn't able to and it was then that I noticed my car had slipped to neutral on it's own. I was on a busy road when this happened. The car also restarted on its own and I was able to shift to drive and continue driving. Thinking this was a fluke or perhaps a battery issue, I continued to drive for a few more minutes and again I found myself at a stop light and again, the car slipped into neutral. I quickly put my emergency lights on and restarted the car. The radio came but on, but I noticed the A/C did not come back on. I didn't bother turning it back on. I was able to drive 23 miles to my destination with no other incident. The majority of the 23 mile drive, after the car had stopped 2 times, was highway driving, so I did not need to stop much.

I checked the Carfax report for my car and there is a minor damage reported on 01/27/2020. It s not correct. My car never had any damage. Never. And there`s nothing there showing who did this report so I understand that it is a mistake and should be fixed please. Thank you.

1) the truck opens for no reason whether the car is parked or driven without trunk feature being activated. This happens when driving down a 4 lane highway at night and day. 2) collision prevention of light displayed & won't go off. (see attached). Google indicates that the passenger air bag has an issue.

The collision assist has malfunctioned since I bought this car in 2016 from the Mercedes dealer on capital expressway in san jose. They will not fix it, they turned it off and now I have a warning light that will not go away. Before I had it turned off, it used to break suddenly and make a loud noise and flash lights when driving down the street for no reason. It was a distraction that could cause an accident. The dealership phone number is 408-579-9087, I spoke with scott fuller and brian woods

Sunroof shade has un-glued itself in a matter of time that would not seem to be consistent with Mercedes Benz quality spec.

Sunroof is faulty in this model. Mercedes have recalled earlier models due to similar issue. The have recalled 750K cars today due to this issue and we are seeing similar problems in our 2015 C class. This issue is very serious and dangerous as the sunroof could potentially fly off myself and my wife were driving at normal speed on the highway when we suddenly heard the noise. When we stopped by to check the issue, it seemed like the sunroof was getting detached. When we tried to close it, it made a big bang noise as if something has not been placed correctly. Ever since the sunroof has not been closed properly and we could hear the wind noise inside. This happened couple of months ago

While driving to work on a freeway I suddenly heard a blasting sound and next thing what I saw was there were glass pieces everywhere on my body and in the car. The panoramic moon roof of my car exploded out of no reason. I am very sure that nothing hit the roof or fall on the roof. The freeway was wide open and fortunately I was wearing sunglasses so my eyes didn't hurt by the explosion. However, after taking a medical leave from work and having checked up at the hospital I decided to take the car to mbenz dealership to report what happened to the car and know why it happened. Surprisingly instead of looking into the incident they decided to avoid the issue and indirectly accused me of causing it by myself. I was very shocked and disappointed by the way a situation and the customer was handled. I'd urge NHTSA to take further action to make sure such incidents do not happen to other mbenz car owners. While doing research on internet I found out that my incident is not the only incident, there are many other mbenz owners reported the same complaint about sudden shattering of their glass roof.

Gas cap door does not unlock/open intermittently. Unfortunately, it's happened as my low gas warning light is on. The first incident after trying countless times at the pump I left back to home and the next morning the door was open. Took it to the shop and mb svc tech could not duplicate the problem. This morning it happened again, ............took me about 20 mins of trying to open the lid (somewhat like a push spring-loaded type function) and when I gave up and put car into reverse it opened while in motion. What happens when I need gas and it doesn't open?
