“The air suspension is faulty and leaks. I have had the since 2013 and the suspension has been replaced on all for wheels within days of each other. Costing thousands of dollars in parts and labor.”
NHTSA complaint #11319012, filed 2020-03, 65,000 miles“I was driving my 2012 Mercedes C250 through an intersection on 08/09/2021 when I first heard clunking noises in the rear of my vehicle. Every time I placed my foot on the brakes after that it continued to clunk until I took it to the Mercedes dealership for repair on 08/17/2021. The car had about 57,000 miles on it and was only nine years old, but the dealership said that the entire rear subframe of the vehicle had rusted and was close to completely separating from other parts of the vehicle. …”
NHTSA complaint #11430314, filed 2021-08“Major rust in the welded joints of the Steel subframe. Long crack development along the seams, could have led to catastrophic lost of control of vehicle if the breaks were not found. This is an apparent flaw with the C-Class Mercedes Benz and quite surprising to the Service Reps at my dealership that this has not been a recall issue, as they’ve replaced many. The repair is quite costly, over $5,000. There were no symptoms, warnings or messages. This was found when the vehicle was in for a 10k service. I have a video sent by the technician that show the inspection of the vehicle.”
