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.

To whom it may concern: I purchased this over $30,000 expensive lemon on December 2,2015. This vehicle has been in the service center more than I've driven it. My expensive lemon of an investment is currently at the BMW midtown service center waiting on the arrival of its new engine from germany. I was told it will take weeks. I am very disappointed in my pre-owned certified vehicle. The resolution offered to me is not appreciated by me. Please any feedback from BMW is welcomed.  jerri sow  (601) 955-2100

My BMW Z4 2011 stalled for the third time. This happened in a parking lot as my car was slowing down. The engine shut down completely and I had no power steering. I took my vehicle into the dealership the next day for service and contacted BMW usa. I purchased and installed a dash camera and captured the stalling on the third incident and provided them the footage. BMW usa did a visual inspection and claimed that my after-market led light bulb in my daytime running lights was the cause of my stalling without providing any documentation or testing. Based on their conclusions, they voided my electrical and powertrain warranty and denied any repairs to be made by any BMW dealership per BMW usa. There is a definite issue with this vehicle stalling that BMW cannot resolve and they have resorted to blaming the consumer without proper testing or documentation.
