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.

First the check engine light on, I went to houston momentum BMW dealer to check and they found out that there was a faulty signal from somewhere they were not sure about. They gave me an estimate for than a thousand dollars to find it and repair it. It would cost more if they found out the real problem. I told them this should be under BMW warranty, but they said it wasn't. I refused the work. This case happened few years ago. Now I have air bag light on, I don't know why. I don't dare to go back to dealer to check because I'm afraid they will rip me off again and again. I hope one day I can get rid of BMW and find a more reliable car to drive.

Bought the 2005 Z-4 BMW used from a dealer in high point nc. Drove it and enjoy driving until the warm weather. The steering sticks to a point of being dangerous. To compensate, I steer to the left and car pulls to the left then I bring the steering back towards the center and feel it sticking so I compensate by steering to the right. The whole time down the highway I fear for my life driving this car. I really had to concentrate to keep the car from steering off the road and I'm sure it appears I'm driving erratically to others on the road. The warm weather will soon be here in North Carolina and I'm just scared to drive it. The car otherwise is beautiful. But if I'm going to be a repeat customer to the BMW line I need to get this fixed or they should recall it and I don't feel that I should have to pay for this problem and sounds like many many others have had the exact same problem from what my research shows me. Please help before someone is killed. Seriously I'm scared ! I contacted BMW in Ohio and they need me to validate the problem through a dealer which I will do but I have to wait til the weather is warm again. Luckily I am employed and will be able to pay the $125 diagnostic fee. The consumer also stated every time she rode over a bump in the road, the radio would shut off and then come back on at random times. The dealer was unable to find any loose wires. Also, the oil filter housing was leaking and an oil leak separator was sauing air to dispel into the engine. Updated IVOQ 04/16/13

Driving on freeway, going about 72 on a warm day, about 86degees. Felt car slow down, like tires were stuck to pavement and could no longer steer car. Steering wheel became very tight, and car was hard to handle, and hard to turn.

I have a 2005 BMW 3.0 w/auto transmission. My car has had two recurring issues from time to time starting with the electric power steering light engaging with the power steering going dead at idle or at corners. The other problem is that my car has stalled with the car shutting down thrice on I-95 and on local roads. Needless to say, it was a life and death situation twice with my girlfriend swearing never to drive the car again. How it happens? at speeds of 40mph or less, eps, ABS, brake, dtc comes on and off with the navigation screen opening and closing. Then abuptly at slow speeds, the car just shuts off. Remedy: Pull over, off the car and on it back again and go.

On August 7, 2007 I took my car to sterling BMW in newport beach, ca because I noticed the airbag malfunction lights were on along with other electrical issues. After they had inspected my vehicle for three days I was informed that the airbag/electrical problem would not be covered by the BMW factory warranty, and the service department recommended that I file a claim with my insurance carrier. Obviously my insurance company denied the claim, because automobile insurance does not cover loss due to wear and tear, mechanical or electrical breakdown/failure. In addition, sterling BMW charged me $260 for the loaner car they provided for the three days while my car was being inspected. Sterling BMW gave me a verbal estimate of approximately $10,000 in additional work needed to repair all the electrical/airbag issues. When I took the car to irvine BMW for another estimate, they advised me that they could take care of the problem, however after three days I was again informed that they the airbag/electrical problem would not be covered under the warranty. I moved to California about one year ago and purchased this vehicle on from excalibur imports in studio city, ca on March 28, 2006. Although my previous vehicle was a Mercedes Benz, I decided to purchase a BMW and benefit from the extraordinary customer service of BMW. This is, in fact, my first experience with BMW. I have always taken excellent care of my car; it has always been garaged, and maintained by BMW dealers. I have always use premium gas to ensure quality of performance and maintenance. To my regret, I have been driving this car for over a year without airbag protection. The nature of my job requires me to commute over 100 miles per day on the freeway. Please be advised that my family and I are extremely worried about the risks that I am taking because of BMW's failure to properly maintain my vehicle. I am a single mother of three and find I am now afraid of driving because of the consequences of an acid.
