UNKNOWN OR OTHER
I was driving on the highway, with no other cars near me and my panoramic sunroof exploded. It made a very loud gunshot like sound and I felt shards of glass fall on my head while driving. I had 2 other passengers In the car. One in the passenger set and one in the rear passenger side seat. They both had glass hit them in the face on head and go inside their clothes. I was extremely startled thinking that someone had shot at us or something and had to quickly take a highway exit to pull over and see what happened. Apparently this is a common thing with Mercedes as there is a class action lawsuit relating to this issue.

FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL, AIR BAGS
1.What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel system failure is a highly critical safety concern, and my life is at risk. It causes malfunctions with the vehicle, for example, the OBD-based emissions test has flagged a lot of (codes P219A, P0300, P0304, P0410, P0305, P0303, P0171, P0301) 5 of the cylinder misfire codes with the check engine light on, as well affecting other parts in the vehicle function properly, acceleration issues, car stalling as though it’s going to shut off. This is a serious matter and Mercedes-Benz is failing to prioritize customer safety, over cost especially when known faults in the vehicle can lead to potentially life-threatening incidents such as fuel leaks and fire hazards. Yes, the vehicle is available for further inspection upon request immediately each day my life is at risk. 2.How was your safety or the safety of others put at risk? My safety and other's safety are put at risk every time I get out on the road to drive my car it's putting me and other' live in serious danger (especially with the extreme increase in car accidents in the local Nashville, TN area). Despite the vehicle now being 3,000 miles over the 150,000-mile extended warranty threshold. I recently purchased the car on [XXX] and was not made aware of Mercedes Benz having any extended warranty coverage for the faulty fuel system that Mercedes-Benz had placed on this model. I can only assume the previous owner the car was reposed from was also unaware of this as well. I believe Mercedes-Benz should still cover the cost of this repair. The fuel system failure is a critical safety concern, and Mercedes-Benz should prioritize customer safety, especially knowing there were faults of poor quality that they discovered with their vehicles and can lead to potentially life-threatening incidents such as fuel leaks and fire hazards.

SERVICE BRAKES
Rear subframe rust out and rear passenger brake line corrosion. The entire subframe has to be taken apart in order to reach the brake line. The vehicle is due to get the rear subframe replaced as part of the warranty extension. The brake lines are not covered. Took it into Mercedes Benz Dealership in Santa Fe, NM. They will not even touch it because they don't even know how repair it.Also they never done this type of work.

UNKNOWN OR OTHER, SUSPENSION
I just purchased a 2011 Mercedes C300. I was told that for the past 2-3 years the vehicle would constantly bald out the rear 2 tires and would need replaced every 3 months. As I was driving the vehicle I noticed that the rear tires would make weird noises as if it was hutting something. Upon further investigation the rear sub frame is rotted, which based on research appears to be a very common problem with these vehicles. The rear sub frame is rotted in which caused the lower control arms to completely rot off of the frame posing as a serious safety issue for me when driving with my children and a safety issues for others when I drive on the road. On top of that due to the lower control arms completely rotting off the frame it caused the control arms to hit the gas tank which could catch the car on fire. Mercedes has refused to issue this as a recall in due part to their negligence. Customers cannot afford to pay $5000 for a rotted subframe due to negligence from Mercedes. Please research how many vehicles have had rotted subframes for this vehicle. In Germany they will repair the rotted subframe free of charge. Mercedes needs to be held accountable for risking peoples lives.

I believe my car was missed on the panoramic roof issue. I have been hearing a lot of wind and road noise coming into my car from the roof and now my roof is having issues completely closing. A few guys with c300 I know were recalled for the same issue and they had theirs repaired from the dealer under recall and after a few trips to different dealers they told me to try and add it here through the website.

Active headrest on front passenger seat forcefully deployed without any collision or impact occurring. It happened during a gradual stop at red light. Bits of broken plastic were found on the passenger seat after deployment. Cannot re-set the headrest because of broken parts.
