I, 12 years ago was driving my ml 500 Mercedes on us 23 between ann arbor, Michigan and sylvania, in Ohio. My car suddenly lost all power. I fortunately was able to swerve to the right and the car stopped. This occurred twice. I have since sold my car several years ago. I called my dealership in sylvania at the time, and they checked with Mercedes, who relayed that it has to do with the weight of the keys on my keychain. This sounded eerily similar to what apparently has occurred with the GM cars being recalled. Please make sure this issue is investigated further so that no injuries that can be prevented happen.

While driving, ML500 began to brake randomly. Also ABS turned on while stopping and accelerating. Also brakes were constantly screeching. Warning lights for ABS, bas, and washer fluid. Fluid level was fine. I told dealer about these problems before warranty had expired. They ran a diagnostics test and found nothing was wrong. They advised me to bring the vehicle in should the same events occur. (the random breaking began to occur after warranty expired). The problem continued to persist and with the failure of ABS system, I brought the ML500 back to the service center. After two days, I retrieved the vehicle and the cost to repair was $1100. "conveniently" they found the same problems I spoke of before after the warranty was up. We had no choice but to pay to restore function to the vehicle. After taking it home we noticed that the there was no sound in the vehicle. The sound and navigation voice worked perfectly before getting service. And afterwards it did not. We called the service center, and they said to bring it back at our earliest convenience, and they will fix the problem. I assume that this was a mistake on their part. When I returned to restore the sound they approached me and told me that a "voice modulation unit" beneath the driver's seat had gone out, and that it would cost $750 parts and labor to repair. They tried to explain to me that this was just a coincidence, and that the unit was in no way related or circuit linked to the sensors they replaced. I believe that they must have mistakenly shorted it. We have spent almost $10,000 in the past year for repairs to this vehicle and one other Mercedes. They did not good will credit the work so I did not accept the repair service. There is no such thing as a $750 coincidence. The sound worked for almost 80,000 miles before service and now right after it failed... I don't think so. The Mercedes service center refused to do any work for what we believe to be their responsibility.
