“I was driving a 2004 mb e-320 on the road, suddenly the lights on the dashboard were all lit up and then I lost power to the car. I made my way to the curb along industrial blvd near west sacramento. The car was towed to the mb sacramento dealership. A quick scan found a fault code. It was the crank position sensor malfunction. The dealership has to replace the sensor.”

The same warning signs came on and the car did not start. I called mercedes assistance who advised to call 911 and that a tow truck will arrive in 1 hour. …”
NHTSA complaint #10585077, filed 2014-04, 111,573 miles“While driving my 2004 mb E320 to the local grocery store the engine stalled. I was pulling up to a red light at the time that turned green before I stopped. When I stepped on the gas to go, there was no power. I pulled to the side of the road and sat for several hours waiting for a tow truck. The local garage said I was out of gas, put ten dollars worth of gas in it, charged me $60.00 and said the car was working fine. The next time my wife took the car out, it stalled again in nearly the same place. She was not as fortunate as I was and was stuck in the middle of the road. …”
