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.

2011 BMW M3 Owner Comments

problem #5

While driving my car on the road my engine automatically placed itself on neutral, the steering froze, and the engine turned off. After turning the system off, I turned it back on and drove away normally. Once I approached the a stop light the car did the same thing again but this time it had a cracking-rattling noise coming from the engine. Without any warnings or check engine light, oil light, my car suffered from broken main and rod bearings as stated by the BMW dealer. This has caused a lot of metallic debris throughout the engine causing engine failure.

2011 BMW dct M3 engine turns off by it self while driving through intersection. Transmission goes into neutral. "N" pops up on the center cockpit. Steering wheel lock. Brakes work. Had to maintain foot on brakes. Have to push "engine start" button. Car starts up again. Engine stalling and shutting off is a safety hazard, especially if the car is in motion. Could cause death to end users or other people. Can cause property damages as well. This has happen twice within a 8 week period. Most recently on Nov 26,2014 approximately 430pm BMW "auto start stop function" ruled out because the led light above the button is lit, function is disable.

Ticking noise in the engine gradually got louder. Oil warning that it was low on oil. Added oil, still said it was low, then said it was too much. Then said it was low (particles from bearings were clogged in oil sensor giving false reading). Finally parked car when noise was so great that I thought it was going to blow up. Rod bears disintegrated on cylinders 2 and 5. had to replace the engine.
