My 2001 ml320 has an intermittent starting problem. The symptoms are the same every time. The remote will not open the lock, once you manually open the door, the car will not crank. You can turn on the radio and the dome light. This problem seems to happen after a short drive. The Mercedes dealership has been working on this problem for 10,000 miles and cannot figure out how to fix it. The car will crank if you wait an hour or so to try and start it after it doesn't crank. I'm going crazy over this. Any help would be greatly appreciated.
