One problem related to steering has been reported for the 2002 Mercedes Benz C230. The most recently reported issues are listed below.
After placing the vehicle in park, I pulled the steering wheel lever lock, (red warning light came on), and adjusted the height and depth of the steering wheel. I then pushed the steering wheel lever lock back in (red warning light disappeared). I started driving and while I was making a right on a curve the steering wheel slipped out of place and almost caused me to swerve into another lane. I pulled over attempted to reengage the steering wheel lock in several different positions, but it would not stay locked. The red warning light only comes on when the steering wheel lock lever is pulled out, but it does not show that the steering wheel is disengaged when the lever is pushed in even though the locking mechanism does not function. I looked online and found a forum with several other people having the same problem on a variety of different vehicles of different years. I feel it is dangerous to operate my vehicle.
