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.

After starting up my car, there was a slight whine under the hood. I gave the car a little bit of throttle to see if the whine went away and heard a loud bang. The car was still running but my battery light was on. I needed to get home, and I thought that my car may not start again if I turned it off so I drove home. Immediately I noticed that I didn't have any power steering. As I drove my engine temperature got higher and I barely made it home without overheating. A few days later I looked in the engine compartment and saw that the power steering pump had broken free of the engine - the bracket had sheared off. That in turn caused the belt to fall off which was turning the water pump and alternator. I got on the computer and looked up the problem and found a lot of people experiencing the same problem, some driving during the incident. This is a real defective design and causes me to be concerned about the safety. I hope nothing tragic has to happen to someone for this to be considered a recall.

I was driving in stop and go traffic when I noticed the steering felt a little stiffer than usual. After about 5 miles and better flowing traffic I pulled into a restaurant for dinner when my upper radiator hose exploded. I pulled into a stall and opened the hood to inspect what happened. The hose was very apparent and after further investigation I noticed the power steering pumps pulley at a very sharp angle compared to linear with the serpentine belt. I can only assume that from the bracket on the pump breaking, it caused a chain reaction of events. First the bracket brocket putting the pump at a steep angle N forcing the belt to go off track which then caused all the other accessories to be disabled including the water pump which overheated the car.

I went out to my BMW 540I and found the driver's power seat all the way back in the horizontal position. I did not leave it this way, so this was confusing to me. When I attempted to move it back upright into a comfortable driving position, it did not respond- the seat was dead. I could not move it manually, either. I was forced to drive the car a short distance to drop my son off at an activity, so I decided to drive it and lean forward while driving. My plan was to take the car to my local BMW mechanic later that night and drop it off to be repaired. My son and I were only two minutes into our drive, I was leaning forward, and he said "do you smell smoke?" I did smell it, and was looking around to see what was wrong. Then my son said "dad, your seat is on fire!" I looked down, and saw flames coming out from under my seat. We pulled the car over and put out the fire with his water bottle. The heated seats were not being used, this happened on July 19th, during the summer. My local BMW shop is telling me this is a $3100 repair. The part in question that caused the fire, per the claims adjuster, is the "general module." I understand the car is 10 years old, but it simply blows my mind that a car can randomly catch on fire internally like this. BMW North America is not taking ownership to this situation, and has offered no help.

Multiple instances of no start. Every time the car was towed to a BMW specialist who over and over again diagnosed completely drained battery, but charging system was ok. I have just found out that BMW has been recalling 2003-2010 models with the exact same defect.

Apparent computer malfunction caused windows to fog up, clock to fail, directional signals to fail and the engine to refuse to restart. Also, the dash display and brake lights remained on even with the ignition key removed. Disconnecting the battery, waiting about one hour, reconnecting the battery restored normal operation.
