| Service Brakes problems |
Total shutdown of complete system…brakes, steering and engine at around 25-to 30 mph. No warning. Happened two times…once before m-b service and once after service for problem. It checked out ok from dealership months before only to have it happen again. Was lucky to avoid a crash both times. Sold to dealership. Wrote my safety concerns for a new owner to local dealership and corporate.
Rear brake lines corroded leading to loss of brake fluid while on the road. My at the time 4 year old son and I were in the car (I was the driver). This was in December of 2022 so almost two years ago. Earlier that year, mb dealership warned me about rear sub frame being corroded, too, but the cost of repairs ($7,000) were out of reach. There were no warning signs the day brake line started leaking other than a dashboard message to check the brake fluid and I felt I could not really stop my car. Car was taken to a local shop and the rear brake lines were repaired for $1,158. On 12/12/2022. Then this spring 2024 rear sub frame fell apart while switching my winter wheels to all year wheels/tires. Mb USA honored this repair through the extended warranty.
A dashboard warning indicator came on, indicating my right rear tail light was not functioning. I opened up the trunk, and located the harness that holds the rear tail light light bulbs. There was a burn mark in the harness that holds the light bulbs. I took the car to my dealership, and they told me the wiring shorted out, and it needs replaced. I have the pdf file that the dealer sent me indicating this is what happened. . . . There is an outstanding nhtsb complaint filed already. . . Read more...
