“All of a sudden the car would not start. I was at 61k miles and warranty expired about 10k miles ago. Now I am experiencing this problem. An mb tech came and said the battery was not the problem but most likely a sensor issue and that this model has had many complaints of this and that it will happen again. Well it kept happening all this week until the 11th where it really went down hard in traffic, luckily this time my kids were not in the car. …”

Once when I was turning in a very busy intersection with my little baby daughter we almost got hit cause the car died out on me. I have taken the car in to the dealer 4 times in fact it is in there now for the same thing and they cannot find what is wrong with the car.

“I would say within a year of getting the vehicle while at a stop the car suddenly started to shake and almost stall but I removed my foot from the brake and started to accelerate some and it went away. This happened atleast 3 other times since then and it is now dec 2009. The vehicle was brand new when I got it in march of 2005.
