My gas door has fell off 3 times exposing my gas cap. I got it replaced twice. It fell off on the highway and the other times I was just doing gas and it fell off into my hand. No excessive force. I didn-??t want to pay again to repair it so I just taped it.

I currently have a 2017 Mercedes C300. The panel between the windshield and main panel of the panoramic roof (above the driver) is deteriorating and doesn-??t not seem to be fully attached anymore. I had the exact same model but a year older in the past and this same part deteriorated and was subject to recall. I believe there is not only an issue with the part itself, but how Mercedes has bonded these parts to the roof.

Panel between front windshield and sun/moon roof was vibrating loose as well as the clear coat completely peeling off the piece. The car is only at 57k miles so this should NOT be occurring. That piece felt like it will fly off while driving. Unsafe.

The glass panel between the top of the windshield and the front of the glass sunroof suddenly detached from the car. I was driving on the I-5 freeway at 70mph when the panel detached without warning. By the time I had safely pulled over I could not safely walk back to see if I could find the panel. The freeway was busy, I do not know if the panel struck another vehicle. It looks like the adhesive that holds the panel on has failed.

Basically, this is a common problem with the c300 coupes, I had an recall to replace front stationary sunroof panel. My sunroof panel started lift the last few months in 2022, therefore I took it to the dealership at the start of 2023 which they notified me this was a big problem and was unsafe on the road because it will eventually lift off while driving. Sense my engine lights were on and needed immediate attention, I had my car service which cost a lit of money. I had one problem about why would I be charged $400 for windshield seal which I assume was apart of the problem with sunroof panel seal. After car was in shop for quite some time, they fixed my sunroof panel that had an recall. About a month later, the sunroof panel was lifted and started to come off. I brought the car back into service which service advisor notified that he ordered about sunroof panel. I called the service advisor about once a week to check sunroof panel but I kept getting the run around for months. Finally, recently I went to another dealership and they told me that about 30 sunroof panel were in stock at near by warehouse which means the previous dealership was not trying to fix the problem but were happy to charge me 8k to fix my car. Please I need help with this situation and I will attach photo of invoice. Please I want to know of I can have another recall on the same particular problem. Thank you

Repeated Panoramic Sunroof failure: sun roof rails are have been reported by the dealer to fail / crack and allow panoramic sun roof to dislodge from tracks securing this structure to the vehicle. NOTE THIS IS NOT RELATED TO/ADDRESSED BY THE PREVIOUS RECALL Loud cracking noises heard and the sunroof stuck in an open position and appeared at risk of departing the vehicle on initial occurrence 2019/2020 Dealer attempts to repair resulted in replacement of the rails which are reportedly "made of plastic and do not hold up well in southwestern US temperatures/climate" Repairs/rigging the system appears to "load the rails" and dealer reported life limits can be as low as 10 cycles / 30 months This issue has occurred three times in the past 4 years 92k miles Improper closure/ cracked tracks could result in incomplete cabin security during a roll over and/or potential for the panoramic sunroof to depart the vehicle to become a threat to other traffic.

I hit a bear in Montana in my 2017 Mercedes C300 at 86mph and destroyed the front of my car. The seatbelts deployed and wrenched us into our seats and smoke came out of the front air vents but the airbags did not go off. On the dash the vehicles stated that the airbags in all 4 zones in the car malfunctioned and service is required. Mercedes is stating that the light is from a seatbelt error code but the dash did not say anything about SRS or seatbelts. I do not want to put my family back in the car and do not feel it should be repaired. Please see attached photos of the error messages on the dash. I do not know how I can hit something that hard and not have them deploy. Mercedes is doing an internal investigation but they have not given me the results of that and it has been over 3 weeks. Vehicle was in for a airbag recall not takata related on January of 2018 and this was supposed to have been repaired.
