Panoramic sunroof spontaneously exploded while the car was sitting. Mercedes claiming something fell into it, but there was nothing above it or in the car while it was sitting in the garage. After reading online, this is happening to a lot of other consumers, including one who has started a class action lawsuit in California

I was driving at approx. 20-25 mph during day light and all of a sudden there was light blinked on my dashboard for applying the brakes because of another vehicle ahead of me. I applied the brakes as well as brake assist plus system got activated as well. But still my vehicle end up hitting the vehicle ahead of me. The brake assist plus system which is claimed by mercedez to take brake automatically to bring the system to halt in case of emergency did not work and it end up hitting another vehicle in front of my vehicle

My sunroof exploded/shattered while I was driving today, traveling at a speed of 45mph on city road after turning a corner. Outside temp was around 85 and inside car was 75. Car has around 6800 miles, and there was nothing that hit the sunroof. Scary situation for the driver! car is currently under warranty and at the dealer for repair, but they want my insurance to pay. I insist this be investigated because I believe it to be a manufacture defect

I was driving 580-E and merging onto I-5 S when I hit a humongous pot hole with my left font tire causing it to immediately blow out. That in-turn caused my stability tracking to engage, which caused me to slow down drastically. That caused another vehicle to near miss ramming me in the back and me side swiping another vehicle. I was driving approximately 70 mph and almost lost control of the vehicle and had to immediately pull over to a very narrow shoulder of the road with my emergency flashers blinking. To ensure the safety of the vehicle, my self and other passengers in the car, I had to drive approximately 0.5 miles to the next exit (67) to safely get my vehicle off the road to a safe location. I then called a tow truck to tow my vehicle back to santa rosa where I live to get the tire replaced and front bump repaired. I am unsure of the cause of the unsafe condition of the highway or what caused the pot hole. There were several cars stranded with damages to their vehicles as well. One person came to the same exit (food mart on patterson road) with a blown out tire as well. I have her contact information if you need to contact her.

My vehicle, a 2015 Mercedes-Benz C300 purchased on 6/6/15 with approximately 1200 miles on the odometer. On Monday morning 7/20/15, at approximately 5:30 am pdt, I was driving on the freeway when the interior lights came on and the drivers door popped open. There was no warning chime or indicator light prior to this happening. It was very frightening, and caught me by surprise. Luckily at the time there were no other cars near me. I was able to slow down and shut the door. I called the dealer and they were concerned and had me drop it off that afternoon. Picked up on Tuesday afternoon 7/21/15 approximately 5:30 pm pdt. I was told they couldn't duplicate the door opening. However, looking at forums on the internet, this exact issue has been reported by others in the us and australia at least. Some were the drivers door others were the passengers door. One reported it happening a second time after the dealer inspected. I am very concerned about this happening again, and possibly triggering an air bag or auto-park. I do not feel safe in this car. I have contacted Mercedes-Benz usa via chat this morning 7/22/15 and they will have a case manager contact me.

Soon after purchasing Mercedes, discovered the following potentially hazardous safety issues (all of these features are standard): 1) new "keyless-go locking system is factory programmed to unlock all doors when key is in owner's possession & rear driver's door handle is touched, allowing intruder(s) to easily enter other side of vehicle. 2) new command/computer/touch pad system, controls various operational functions, like radio, encouraging driver to take eyes off the road to operate. Touchpad requires driver to make "mouse-like" actions on computer pad (located on console) while simultaneously driving. 3) new air flow & vent system, circulates air from grill to windshield, allowing leaves & other debris, incl. Water, to enter engine compartment at the top of hood. Debris lodged here could potentially result in overheating & cause fire or result in damage to wiring and/or other components of the engine. 4) letters (w/pictures) sent to mbusa, CEO, resulted in phone calls from subordinate staff, rejecting outright each complaint but advising that debris in engine area is "normal" & customer's responsibility to remove. Letter to daimler's CEO in germany was referred back to mbusa. 5) asking for your intervention before these problems potentially result in injury or fatality. If this is not the office to investigate & intervene, please forward to the correct Agency & advise accordingly. Can provide additional info. On request. Thank you...
