Equipment Problems of Mercedes Benz CLS550

The vehicle sunroof exploded while traveling on the interstate. Stopped and inspected the vehicle to find no impact objects inside the vehicle. Later reviewed online that this was a common problem with this modern mercedes and the item is already under recall but not my year. I have a 2012 and the recall stops at 2011 although 2012 sunroofs are exploding too.

The rear subframe rusted from the inside out causing structural failure of the subframe. This lead to twisting of the chassis under hard braking causing difficulty in controlling the vehicle. As you can imagine, controlling a vehicle when needing to abruptly stop is very important. The rear end felt like it was getting loose and it was very difficult to keep the car moving straight. This type of rust isn't typical on a 10 year old car with only 85,000 miles on it. This is a known issue on other Mercedes Benz models, notably the w204/c class, to the point where it was recalled in canada and covered under the european corrosion warranty. However, nothing is covered in the us even though this issue is known by mercedes in other countries. This has been repaired at my expense. There were no warning messages. This vehicle has been dealer-serviced for most, if not all, of its life and this was missed on every single multi-point inspection done to the vehicle. Had I not been cognizant of how my car should drive and handle or not been able to afford the repair out of pocket, this would escalate and worsen to a bigger issue that could have eventually lead to my own injury or death or that of others.

It has been confirmed by a glass company that the car has an improper seal/bonded windshield. The windshield is the original and the car has never been in an accident. A few years ago, I noticed a rattling that I was unable to identify. This was reported during one of the regular maintenance services but the sound was not replicated (as it would happen more often when cold). Recently, the sound has gotten worse, and I had a water leak so I suspected the windshield. As I have already stated the problem was confirmed, and you can literally push on the windshield from the inside and it lifts up. Needless, to say, this is a safety issue. Having owned several cars, I have never had such a problem and would not have expected it from a high-end vehicle.

On March 8 2020 I was driving my 2014 Mercedes Benz Cls550 straight on the freeway when my sunroof exploded, glass shattering everywhere. Glass hit my face and went down my back and cut my hands. I didn't crash the car nor was any other damage done than the sunroof. I pulled over when it was safe to inspect the vehicle and no object had came through the sunroof. The front of the sunroof was indented inward and glass was angled outward as if it had exploded from the inside out. I researched online to find that there was a recall for 760,000 Mercedes Benz years 2001-2011 for defective sunroof. My car being a 2014, falls out of that demographic. There is a current class action lawsuit for the newer makes and models of mercedes for the exact same issue, "exploding sunroof. " I took my car into the shop on March 9, 2020 to Mercedes Benz of marin. Mercedes benz of marin was not willing to help or assume responsibility for the repairs so I have reached out to Mercedes Benz USA who is doing an investigation of the issue. I am waiting to hear back, however I am not optimistic as mercedes has not been helpful thus far and my car has been in the shop for over one month. The fact that this is a recorded issue and mercedes is not doing their due diligence to fix it is criminal, as I have a family and luckily no one else was in the vehicle, nor did I crash into someone else or something and get severely injured or die.

Sunroof recall - the panel has become loose and the covering needed to be removed for safety (falling). I called my local mercedes dealer for the recall replacement and they said they do not have the parts. I asked can they call me when they come in and they said they cannot because they don't know if they will ever come in. They offered no solution.

Note that the vehicle on has 43,733 miles - cabin interior strong live fuel fumes - constant gas fumes on the inside of the car cabin. Note that the car was stationary at my residence parking. I did not know where were the fumes coming from at the time. Got a headache just for the moment I was trying to determined where were the fumes coming from. This is currently for all drivers and owners a very hazardous dangerous condition to all extremes, very high risk from ignition from static or electrical, due to wire hardness in the area. Vehicle was towed and took it to Mercedes Benz dealer and found the following: leakage in fuel system. Replaced fuel tank fuel tank drain/fill observed accident prevention regulation "12 wl08" fuel tank and fuel for storagebring observe accident prevention regulation "12 wl08" performed by mercedes-benz of new orleans. Fuel tank leaking in the interior was found / was drained & refilled and fuel tank replaced. This was cover under a new settlement with Mercedes Benz and NHTSA. I think that this should have been a recall when it relates to safety factors.
