Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I was driving on the hwy 94 in Minneapolis and I had the cap to my sunroof fly off on the freeway. There’s a recall out on the sale vehicle but 4matic but not on my vin number. This is a huge safety issue and it’s been happening to quite a few people I know. No one was injured and it didn’t cause damage to any other vehicle but when I brought it into the shop they said the recall that was on this part was not for my exact vehicle.”

NHTSA complaint #11691716, filed 2025-10

“The seal around the sunroof on the driver front side is compromised causing air to flow aggressively through it when going above 40+ MPH. Its affecting the car's overall performance and safety, especially on highways, and the wind makes in very noisy in the vehicle. I have an appointment with MBUSA dealership on Monday, August 12th to have it further inspected. I do see that there was a similar recall for my class of car filed in December 2023 that appears to be related 23V85400.”

“The automatic trunk lid started to close and hit my head while I was loading groceries into the trunk. It also started to close and hit my wife in the head when she was unloading the groceries about 15 minutes later. This situation was not reproduced or confirmed by a dealer or independent service center. There was no notice or warning of pending failure. There appeared to be no visible injury to either person except for a short pain in the head.”
