problem #1

Jul 102010


  • 70,000 miles


I drove up a 6000' high mountain, pulled over onto a wide flat pulloff sat there for 20 minutes, then restarted the car and had no brakes. My foot went to the floor. I had not used the brakes on the way up the mountain because the road was steeply uphill. I tried turning the car on and off several times and still no brakes. I waited about 20 minute and tried again, still had no brakes. There were 3 of us in the car, and we managed to get a ride several miles down and called a tow truck. I T took about 4 hours for them to arrive.I tried the brakes again, and still had none. After it was towed to a repair shop, approximately 5 hours after the initial problem, I still had no brakes. This happened on a Saturday night. On Monday, the brakes had pumped back up. I had it towed to penske Mercedes dealership. They tested-brakes, fluids etc. And could find no problem. They balked at driving it up the mountain, but finally said they did do it, and the brakes were fine. This all happened over 3 weeks ago. I have spoken with 3 levels of authority at the dealer, and they insist there is no problem, and I should pick the car up or have it towed away, or pay them a $25 per day storage fee. I also called the 800 number for mb corporate, and have never received a call back. The dealer said they were contacted by corporate mb and told which tests to perform, and they told them they had already done those same tests and the car passed them all. Mercedes corporate then told them to tell me the car was fine. And I should pick it up. This is the second time I've had the same failure, also at the same altitude;however the first time, after turning the car off for a few minutes, the brakes were back up and usable. Just because the car passes their tests does not mean there is no problem-it simply means they have no test capable of discovering the cause. Must I die before they repair the car? I was going to make U-turn at the pull-off. We're alive because I didn't get that far.
