| Problem Category | Number of Problems |

| Wiring problems | |
| Power Door Locks Not Working problems |
While driving at highway speed in the left lane of a divided highway, the vehicle suddenly and without notice lost engine power and power steering. The weather condition was light rain and the road was wet. I was able to move over to the shoulder of the highway and restart the engine but it died within two to three seconds. I then restarted the engine several more times and was able to maintain a running engine after about 5 restart cycles. The engine loss of power has been traced back by a mercedes repair center to a malfunction of the electrical wiring harness connected to the fuel pump in the gas tank. This incident demonstrates that the electrical system malfunction reported under item #10745399 occurs in wet road conditions and not just when traveling over a puddle. Mercedes refuses to repair this safety related defect under warranty.
