5 Steering problem

Failure Date: 03/06/2022

I drove over an object on the highway and noticed my car veering left and wobbly when turning. A week after, it is squealing like a load of piglets in my trunk whenever I go over a bump, then my battery light came on and I took it to the shop and contacted my insurance, who denied my claim saying it was 'wear and tear'.

6 Steering problem

Failure Date: 01/24/2022

While driving, engine stopped, could not steer. . Looks like a defective electronic ignition switch or steering lock! it seems to be a common problem on these cars!!! the car would not start. After 8 attempts, I was able to start car but was afraid to drive it. Could have been a disaster.

7 Steering problem

Failure Date: 08/03/2020

The rear subframe has corroded around the areas where the trailing arm and control arm meet the subframe on both sides of the vehicle, and has disintegrated around the drivers side rear trailing arm causing it to have detached, along with a piece of the subframe. The metal of the subframe is distorted around the area of the break. The detached trailing arm and piece of subframe are now making contact with the fuel tank as well. The fuel tank could have easily ruptured and ignited when this car was still in operation, as this car was driven for several days before the manufacturing defect was discovered. The failure happened when coming to a gentle stop from 20-30 miles per hour on a straight road. There was a loud snapping noise from the drivers side rear. This car had 92,000 miles at time of the structural failure and has been regularly serviced, exclusively at mercedes-benz. Mercedes-benz USA customer service is unable to offer any assistance. This exact issue has led to a recall of the same model in canada, and there are countless NHTSA reports describing similar structural failures. Mercedes-benz USA is aware of this issue and is also aware that there is a recall in canada, but has made it clear that goodwill will not be extended.
