Electrical system: “When taking curves the vehicle is making a cracking noise but, mechanic said they don’t see anything. My W213 Mercedes Benz E300 just like all other Mercedes is have a “Crankcase” issue, it failed the engine keep revving but, not catching speed.

Other or unknown: “I was in an automated car wash and the car was in park. When the wash was complete, I put the car in drive, but it would not moved forward. The proximity sensors kept sounding though there was nothing in the way. After shifting it in and out of gear, turning the steering when back and forth and pushing the accelerator to the floor for several minutes, the car finally shot forward out of the wash bay. I later called the in-car customer service line and they said that sometime the sensors get covered with the products used in the car wash.”

NHTSA complaint #11132217, filed 2018-09, 4,592 miles

Transmission and drivetrain: “The car did not give any warning before this issue came about. A matter of fact when I took it to the mechanic they were unable to do a diagnostic test because there were no error messages and check engine light never came on. After taking it to the dealership they were able to check the history and saw that the error code P061b00 shows that the clutch position switch module needs to be replaced. While driving in traffic the car went into N (neutral) and wouldn’t not go back in D (drive). It took several minutes of me trying to change gears but it eventually went into P (park). …”
