Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Low battery situation over the winter caused the vehicle to slip into "Transport mode" where the ac, defroster, and fan speed will not work. This creates a hazardous visibility situation due to the defroster not working. As I understand it, the Transport mode is supposed to be disabled when the car is delivered to the us but some dealers mistakenly turn it off rather than disable it. To disable it you must return it to the dealer and pay for a high service visit for a few moments of programming.

While driving straight, the steering wheel tends to stick, force is needed to steer to the left or right or to even keep it going straight. Once you start turning it seems to feel normal until you start to move the wheel back to the neutral position, then you realize the wheel is now stuck in this position. It usually takes quite a tug to get it moving again! it appears to be getting more extreme and requiring more force to move the wheel. I have owned the car for about 2 1/2 years and have always thought it steered a little different, I just figured it was a BMW thing and it being a smaller car that was causing it to handle this way!! I don't think that any more!

The wiring harness under the dash spontaneously ignited while I was driving. The fire was put out with a fire extinguisher, but re-ignited two more times. It didn't stop re-igniting until the battery wires were disconnected from the battery terminals. Police and the fire dept were called.
