Example complaints

Wheels: “I have had to replace 3 wheels at great cost due to cracks. I believe the wheels are defectively designed. The wheels cannot support the vehicle's weight. The cast iron aluminum wheels together with the low profile run flat tires contribute to a road hazard and dangerous condition. I understand that this problem has been encountered by many, many MBZ owners.”

NHTSA complaint #11552658, filed 2023-10

Electrical system: “My car started shaking and after putting it on the computer it was an electrical wiring harness issue. I was told it will be 6 k to replace both harnesses. It’s been 8 months and they just received the part. The service tech told me that these cars have this issue due to the position of the harnesses being to close to the exhaust. It dries out the wiring. I went to the Mercedes forum and found numerous complaints about this issue. …”

Steering: “Upon driving over certain bumps in the road, the suspension has the sensation that the wheels and/or lug nuts are loose. This produces a disturbing side to side movement that feels like the vehicle lacks control. This condition is related to the fact that rotors wear out prematurely; two sets in 4700 miles. Bad rotors produce a shaking steering wheel when coming to a stop. Even after replacing rotors and the repairs appears to be done, the shaking steering wheel comes back readily after an episode of hitting bumps that produce the side to side movement. …”

NHTSA complaint #11280637, filed 2019-11, 250 miles

Engine: “My car cut off on the busy 405 freeway as I was driving. I have had the brand new car 3 months . I stared to receive the following alerts on the car panel: blind spot assist inoperative , active brake assist functioned limited , attention assist, system suspended . The call slowly stalled on the freeway. I had to exit on the shoulder of the freeway with my hazard lights on. The car cut off. It started again. I tried to continue my trip, but the same issue happened 2 more times. I exited the freeway near ucla . Mercedes roadside assistance picked up the car for tow. This happened on may 28th. …”
