The plastic trim/cover that wraps around the steering wheel column and is the same color as the seats and interior heats up, melts, becomes brittle after the fact but could is fire hazard, especially with melting plastic falling into the driver-??s feet and/or carpeting. When I googled the replacement part, I found out on The Internet that owners across America have had the same problem with their vehicles regardless of the year or model. Some believe there is a shortage in the wiring that allows the steering wheel to be raised, lowered, pushed away or brought closer to the driver. There should definitely be an investigation at the least and then a service bulletin and recall as a fire could definitely occur.

[xxx] steering lock failure should be a recall. Mercedes charges $1100 to replace mine and everything I've read ppl are all having same common issues. I had no issues until after my car was hit in front when someone backed into me (very hard that is). Suddenly many lights on dash came on and next steering lock failure. Ins co said that Mercedes mechanic supervisor said it didn't happen from accident.. and that it's common with these Mercedes bc they are lemons!!! redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

When driving 40 mph or more, the engine stalls and the unit in the dashboard that contains the odometer and speed, begins to turn white in color. It appears the software error within the engine control unit causes the vehicle to stall when driving at a certain speed or when I am coasting to a stop, such as at a traffic light. My vehicle begins to shut-down in the mist of my driving at 40 mph or more, however, when I put my foot on the brake, the engine picks up speed. These events are terrifying, because I can't tell if the vehicle is going to shut down in the middle of the highway and increase my risk of crashing. These events have been ongoing for over one year. I have taken the vehicle to the Mercedes dealership several times, but they can't resolve the problems. I truly need help from the Mercedes Benz manufacturer and/or the NHTSA because I am afraid the vehicle engine will cause me to lose control and hurt myself or another driver.
