NHTSA complaint #11114212, filed 2018-07, 60,000 miles“Security module failed which locked steering and prevented car from starting. Had to toe to dealer and repair was $1000. Many complaints and hundreds of similar failures on this and c class models on internet. This failure stranded my wife in another city and should be considered a safety defect. Vehicle had just been driven to a doctor visit but refused to start after visit. Mercedes roadside assistance technician knew exactly what was wrong when called to the car and stated he had seen dozens of this failure in only the past few months.”
NHTSA complaint #11074162, filed 2018-02, 65,786 miles“After inserting key - there is no response. Tried several times. FOB locks and unlocks the doors. After a couple of days - it started with no problem. A week later, we are having the same problem with no response after inserting the key in ignition switch. This troublesome to know that I cannot rely on the ignition switch working all the time.”
NHTSA complaint #11552551, filed 2023-10“My kids and I went into a football game and when we came out I used the key fob to unlock the doors but the vehicle didn’t recognize my key fob when I tried to start it. There were no lights or warnings leading up to this incident. The dash didn’t say anything besides “remove key from ignition”. We were stranded for 5 hours before I had to have it towed. It cost roughly $2000 to have it repaired with no clear reason for why it happened. …”
