I bought my brand new BMW X3 in 2007. There were small issues in the past but withing my manufacturer warrenty period. I had my rear brake pads replaced on Jan 23, 2012. On Jan 30, 2012, when I drove my X3 out my subdivison to go to work, the brake light, ABS light, and 4/4 light all on, plus load clunk type noise from rear, it was difficault to make a U-turn, managed back to home, called BMW unitedbmw dealer and towed my vehicle to dealer. They first told me that is software failure, they would try reprogram to fix, then called to tell the re-program did not work, it was mechanical transfer case actuator broken, a new one must be installed. The total charge for repair (part + labor - discount) is $2354.97. It was in the dealer for one week. The dealer insisted that it was my bad luck, not car's own issue even though the milage is less than 40K. I did some research online, found that there are plenty of similar cases and class-action lawsuits. Looks like BMW (2007 and 2008) models have lubricant problem, later BMW switched with different lubricant. Internet estimation says that ~30% of the vehichles (2007 & 2008) demonstrated this issue. As a consumer, I am trying to urge any car maker to be responsible for their products. But I never get any notice or recall from BMW dealers or maker in the past and when the problem surfaced.

After being service by dealer for 4 days which included the replacement of right headlight and ABS and brake system the car caught fire which seem to be related to electrical system. While driving the car heavy toxic smoke started coming out of ventilator of ac system. I immediately step out of the car and in a few minutes smoke and flames located in the engine in front of passenger seat burn the car. Flames and black plastic were coming also under the glove compartment right in front of passenger seat. Dealer quoted $25000 for repair and insurance company declared it total loss. Car was delivered to dealer who has kept it for a month, engineer from BMW North America came and inspected but no report has been issued by them or dealer. This company has no concern for safety of consumers and should be penalize. After having owned six BMW's I feel these autos are not safe.
