  • Recall 217835 [USA]: A disabled ecall system would prevent a vehicle occupant from contacting the emergency services call center in an emergency, potentially delaying emergency responders and increasing the risk of injury.

  • Recall 209064 [USA]: An inoperable rearview camera display reduces the driver's rear view, increasing the risk of a crash.

  • Recall 167729 [USA]: Failure of the ecall system may result in emergency responders being dispatched to the wrong location, increasing the risk of injury following a crash.

  • Recall 155020 [USA]: Without the audible tone and blinking warning light to remind the front seat occupants that their seat belts are not buckled, they may forget to buckle their seat belt, increasing their risk of injury in the event of a crash.

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. I still do not have answers as to what is wrong with my car. The roadside rep said this could be due to sensitivity of safety feature that detect cars around the car. If reading incorrectly , car can slow down or beep - but this car stalled. I could have hit from behind of killed. I will report this to mercedes corp

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. The side to side, fishtail, sensation happens on the freeway and surface streets around 40-60 miles an hour. This condition is disturbing and makes it seem that the next well-placed bump on the road would cause the car to lose control.

Tl* the contact owns a 2019 mercedes-benz cls450. The contact stated that the vehicle's wheels were not designed for daily driving. The rims were bending underneath the vehicle while it was in motion, which caused a bumpy ride. The vehicle was taken to mercedes-benz of massapequa (101 sunrise hwy, amityville, ny 11701, (631) 213-2023) seven times. The rims were removed and shipped off for repairs multiple times, but the failure recurred after each visit to the dealer.
