Gasoline Fuel System Problems of BMW X3

My complaint is similar to the following: quote NHTSA id number: 10546733 the issue is when you step on the brake the engine races and the car continues to move forward. It doesn't matter how hard you press on the brake you still go forward. End quote brake and accelerator pedals can be engaged simultaneously, particularly in hard braking this 4d 4x4 xdrive 28i (and never happened with our three previous Bmws, which were sedans). Brake pedal application travel can easily fall under the distance to the floor of unapplied accelerator pedal. Traveling that distance the accelerator can simultaneously be depressed. BMW factory inspection found nothing out of spec. I can only conclude it's a design deficiency, a condition type BMW never admits, even if it corrects the condition later.

Every time I fill up my car, the check gas cap light comes on. As I drive, it goes off but then will illuminate again. I check it and nothing appears to be wrong but as I drive, I do notice that the gas needle will move up and down.

Service engine soon light came on. Diagnosed at dealership that it was the dmtl pump that senses and gas leaks. I was told by service manager that it was out of warranty and I didn't have to replace it since I lived in PA in an area that didn't require it to work under our state inspections. The only problem was that the service engine light would be on and I would not know if something else was wrong with the car. Later I was talking to service manager at Lexus who was a former BMW service manager who stated it was covered under PA emission laws. I contacted manager at BMW who informed me that I would have to contact BMW. I registered a complaint with BMW who came back 3 weeks later denying any coverage. When asked why gentleman could not answer stating he was not a technician. I repeatedly stated from my research that PA adopted California emission law in 1996 and from my understanding it should be replaced by BMW. Once again I was told no coverage and I asked if his 3 weeks of research involved a corporate attorney. He would not answer. It appears that a BMW buyer is given 4 year warranty because after that everything is denied with no explanation as to why. This dmtl pump is a sensor for fuel leaks and could really cause a serious accident if not replaced. I believe PA emission laws understand the hazard and that is why they state it should be replaced. This problem with BMW goes back over 10 years according to internet forums. . I cannot understand why they have not been held accountable and made to correct this hazardous situation.

The intake boot between the mass air sensor and the throttle body cracks over time. This causes the check engine light to come on. Even though this is a known failure item, and the car is within the cpo warranty period, BMW does not cover any hoses or tubes, as they believe they are "wear" items. Since it is not covered its a $175 dollar diagnostic fee and $38. 54 for the part vs $50 deductible. You do not know if your repair is covered until the diagnostic, so short of having to take it to another mechanic to have it checked you could be penalized $125 for wanting you car repaired under the extended warranty which you paid extra for.

My 2007 BMW X3 has broken down twice. The fuel sensor monitor has failed. I have less than 9,000 miles on the car. I do not want the vehicle any longer. I do not feel safe. The last time it broke down was on a draw bridge, there was no power!.
