What owners report
Steering wheel will move in and out, but has stopped moving up and down. The steering wheel is stuck in the UP position. This has caused me to readjust all my seat settings and has made it more difficult to see the dash.
The contact owns a 2017 Mercedes-Benz S550. The contact stated while the vehicle was in for routine maintenance, the mechanic discovered that the front driver's side CV-boot had cracked and was leaking oil. The contact was advised that the CV-boot could cause the front axle to eventually fail. The contact was advised that the front axle needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 76,000.
This car since new has had moisture in the headlight from rain or washing. MB has installed moisture packets in the headlights that they said would fix the problem. It never did. I called the dealership and complained, they said sorry but that was their fix (MB TSB LI82.10-P-062051). Now the lights have failed, and they want me to spend $10K to replace the headlights and continue with the same issue. The problem still exists with the new headlights. This is not only a poor way to fix an ongoing problem (Moisture packets) for something that is severely related to safety on the highways in America. I believe you will agree. Please respond? Thank you
The dashboard is separating where the airbag is on the passenger side and also the driver side which could deploy the airbag
I was sold a vehicle by a dealership with a busted gas tank. It appears to have been an attempt to repair it with patching material. I am unsure if the defect was a result of manufacturing versus acquired damage. My safety is at risk because of leaking gas that could potentially ignite and inhaling strong gas fumes that could impact my lungs and health. The fuel tank damage has been confirmed by a mechanic and documented. It has not been inspected by any other entity while in my possession other than reported inspection by the dealership. I secured the vehicle on [XXX] from the dealership with these safety concerns. A mechanic stated the damage could have resulted either with the deal
