“The vehicle was parked at a parking lot for approximately 2 hrs. I attempted to start the engine. It started then abruptly stopped. This happened 3 times. Upon the 4th attempt the engine would not start at all. I looked at the dash lights the computer was showing error start. I proceeded to jiggle the key and even used the second master key. The car would not start at all. I talked with mb roadside service they suggested cleaning the key, jiggling the ring around the ignition key area. Nothing worked. After 2 hours of attempts, I had the ml towed by flat bed truck to the nearest mb dealership. …”
