One problem related to power train driveline has been reported for the 1998 Mercedes Benz M Class. The most recently reported issues are listed below.
While pulling into a parking spot in a shopping center and going about 5 miles per hour, suddenly the accelerator went to the floor and I crashed into 2 cars. Luckily, I was not hurt and the damage to the 3 cars was slight bumper damage. I called the police and made a report. I brought it to the garage the next day to have the checked and no problems were found. The next day I went on the internet the check for similar occurrences and found several. My car was a Mercedes Benz ml320 SUV.
