Example complaints

Other or unknown: “Takata recall. I was driving on the highway on my way to phoenix az to drop off my mom and grandma when suddenly the sunroof exploded. It sounded like a gun shot. There wasn't any type of object near me to cause it. It was very random. This disturbed my family mentally scaring them and I swerved off the highway almost crashing.”

NHTSA complaint #11221366, filed 2019-06, 43,900 miles

Body and structure: “I woke up one morning and was astounded to find a long diagonal crack across the panoramic sunroof of my 2016 Mercedes-Benz S550. I contacted mercedes and was told to bring the car to a dealership for evaluation to determine whether this was due to outside influence or a manufacturer's defect. They determined that it was a stress crack and stuck me with a bill for $13,000. This is a 2016 model car with 50k miles on it with a sunroof that spontaneously cracked. What if my wife and young children were in the car when it started to crack? The response from mercedes is unacceptable. …”

NHTSA complaint #11362560, filed 2020-10, 58,455 miles

Seat belts: “The car's front passenger passenger seat buckle fails to properly secure the seat belt. After inserting the seat belt it fails to latch into the buckle. The Mercedes dealer has examined the seat buckle and determined that it failed. They are recommending a replacement.”

NHTSA complaint #11604634, filed 2024-07

Tires: “Staggered tires on this car Goodyear Eagle F1 Asymetric 2 Run flats. Front size - 245/40 R 20/99y, Rear -275/35 R 20/102 These tires cannot take the load of the car . I purchased the vehicle & the same tire (front driver side) has blown & ripped open over a moderate pothole, Aug 2020 & in Sep, 2022. In my opinion these tires are massive liability and a huge safety hazard. These are Summer runflat tires & also there no Allseason ROF's”
