| 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 $1100.00. 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 $750.00 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 $10,000.00 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 $750.00 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. *tr | |||

| 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. every since i have owned the vehicle ( 2002) i have complained on at least 3 occasions every year, that the car would not start at times and i would jiggle the key and keep turning the vehicle on and off several times. in the past it finally managed to start. when i would report this to the dealership they would state there was nothing they could do until it actually was doing the same thing when i brought it to them. i know there is some part that has been defective from day 1 after we purchased the car. the mercedes dealership had the car for 3 days. they found a faulty transponder ring and also advised me that my second master key would not coordinate with the computer and the new transponder ring. it reads error start. just like it was doing when i had it towed. i have the mercedes returned to me 6 days and i get in the car and the gears are locked. i turn the engine on and off for 5 minutes before i can get the gear to shift into reverse. i called the mercedes dealership. they want me to bring it back tomorrow for them to check some switch component which may be defective. this ml 500 only has 51,806 miles on it. however, i do not feel comfortable depending on it. i am afraid i will be out somewhere at night or in an isolated area and this ml 500 will not start or the gear box will be locked up. *tr | |||
