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.

The electronic steering wheel lock went out causing the car to not start. Upon checking the Internet to see if anyone else was having this problem I found that it was a problem many Mercedes Benz owners have had and it's an expensive one. It's not just with my particular model and it's not limited to older models of the brand either.

I was in a collision and the airbags did not deploy. There was a recall on airbags for the Mercedes C300 within the year my vehicle was made, however, the recall did not include my VIN. Also, the sunroof drain is faulty, which was also recalled on other Mercedes C300s within the same production year, again not my VIN, but upon inspection by a certified dealership, it appears to be the same issue as other recalled vehicles.

The driver’s side door handle broke and I was unable to leave the car unless it was unlocked and rolled the window down to open it from the outside through the window. If there was a loss of power and you pulled on the latch and it broke you would be delayed in exiting. There are multiple videos on after market parts to repair the plastic pin that breaks. Tesla seems to be recalling their vehicles for a similar problem recently, why not Mercedes for a known problem????

While I was driving, my seat back suddenly started reclining backward. I could not make the seat stop or go forward with pushing the power seat button control. It kept reclining back, pushing into the back seat and would not stop until there was no power left. Had my child been in the seat behind me, instead of behind the passenger seat, her legs would have been crushed. I took it to a vehicle repair shop and they were able to manually put the seat back to an upright position. I have not let my child ride in the back seat after that incident yet. I just dropped the car off to the Mercedes service department near me.
