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.

When I put the key in the ignition it will not turn over no lights display on the dashboard. The radio cuts on and the only thing that displays on the dashboard is the mileage no other lights. When the key is turned to first or second position. The day before when my car would not start I was able to take the key out of the ignition and replace it in the car started right up this time it does nothing. I'm being told it's an esl steering wheel lock issue that is common to this car model.

Car was parked in a parking lot. I was 120 miles from home when the engine would not start -- even though the battery, lights, stereo, gauges, etc. All worked fine. Still, the engine wouldn't even crank, had car towed to an independent Mercedes repair facility (it was a Sunday and the local Mercedes service department was not open). The electronic ignition switch (eis) and other parts needed to be replaced at a cost of $1526.94. Months later I visited the NHTSA website and learned that this is a common problem with this model of Mercedes and that the manufacturer is refusing to pay for the repair. With a problem this widespread -- which can occur multiple times during the life of the car -- Mercedes should foot the bill. I would have complained earlier but only now learned that many other owners are experiencing the same defect. My car had only 37,110 miles at the time. I should be reimbursed my Mercedes.
