“The driver's side door handle broke impossible to open door from inside if there was an accident. I have been told that this is a common problem with my car, and that it cost 1600.00 to replace repair at the dealer. This is such a common problem that there are after market kits to repair the broken handle for 20.00, but including labor the repair is $500.00.”
NHTSA complaint #11551878, filed 2023-10“The driver's side interior door handle became disengaged as I was trying to open the door so I was momentarily trapped inside. If I had been in a situation where I had been in an accident and needed to get out quickly, or the car had been on fire, or I was stalled on the train tracks, this could have been a serious incident. When I googled this, it sounds like this is a very common occurrence in Mercedes. There was no warning that this was going to occur - everything seemed secure before this happened. …”
NHTSA complaint #11597583, filed 2024-06“Sub frame on mercedes has rust issue, rusting from the inside out and is very dangerous. I only found out because I got new tires. Only 70k on the vehicle”
NHTSA complaint #11504526, filed 2023-01“Failed component: The subframe on my Mercedes C300 broke on one side and was almost broken on the other. It would be available for inspection as it is sitting in the Mercedes dealer bone yard waiting on the part to be shipped from Germany around September 17th. It also ruined my back tires & now I have to replace them too. I understand that in the UK the Mercedes dealers are fixing this problem free of charge but there seems to be no recalls! Safety: I was entering the freeway on a rainy afternoon. My car was fishtailing very badly. …”
NHTSA complaint #11479919, filed 2022-08“I purchased my vehicle from the Mercedes Benz Dealership and received a recall letter in the mail stating that driver side deployment may occur. After receiving notice I brought the car to the dealership to get the recall repaired. I've been driving around with a false sense of security believing that this issue was repaired. However, recently, while I was driving the driver side airbag unexpectedly and abruptly deployed and injured me. This is a major safety concern and car owners should be notified and made aware that the issue can still occur after the recall was repaired. …”
