Diesel Fuel System problem #2

Letter from regarding numerous issues and troubles he has faced since the purchase of his mercedes-benz vehicle, a 2009 Ml320 blue tec diesel engine SUV; seeking assistance-he would like acknowledgement of receipt of this complaint the consumer stated the first problem he encountered with the vehicle was in may of 2010, within less than a year of purchase, while driving, the gas gauge all of a sudden went from a half tank of fuel, to reading empty, where at that point the fuel light illuminated. Even though he knew the tank was not empty, he stopped to the gas station and re-fueled. However, the tank continued to read empty. About an hour later, the needle moved to the full position. Four to five months later, the check engine light illuminated, along with a blue warning light. The vehicle was taken to the dealer, but nothing was found to be wrong. On another occasion, the vehicle lost acceleration as the consumer was attempting to go uphill on an incline. The vehicle started to slow down in speed. Even trying to pump the accelerator pedal did not help and eventually the vehicle started to stall. The consumer experienced the same failure, several more times after that. The check engine light illuminated several other times as well. The dealer changed the entire computer module. Soon after, the tire pressure light illuminated. Once the tires were checked, the light no longer appeared.

Diesel Fuel System problem #3

This car should qualify as a lemon. We spent over $65k on it new in January of 2009 and it has easily costs us $65k to keep it running since. Something significant breaks on it every 60 days since owning it. The turbo went out most recently after a bad oil seal let oil into it. $6500! the car may have sadly been cursed since day one. Our sales person at Mercedes Benz of sf died right after we bought it. Things started to break immediately after. People ran into it, etc. It has been the worst car owner experience in my life.
