What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I just had the bolts on both the (intake and exhaust replaced) this is listed in the unspecified recall and no one notified me on this recall I drive the 2011 128i series coupe and this cost me out of pocket $1,800 dollars to replace, what I do not understand is why I was not notified of this I could have been in a…
The car was moving at highway speed with ac running. Smoke plumed from vents and under front passenger footwell. Electrical fire stemming from blower motor final stage unit and wiring harness.
The vehicle was in motion and the blower motor resistor harness began to smoke heavily. The a/c stopped working. I pulled over and disconnected the wiring harness and pulled the fuse. The wires melted, the connector melted, and the resistor is broken.
The high pressure fuel pump has failed and been replaced multiple times. It begins with the car taking much longer to crank and start. Then it completely fails potentially while driving, creating a safety issue, or will no longer start. The hpfp is easily replaced with just 3 bolts holding it to the side of the motor.
Takata recall braman bmw keep saying they do not have the parts. I have been waiting for 2 years, and every time I called they give me the same "scripted answer". I have been waiting for 2 years to get this part replaced and they just keep getting my name on a waiting list, that is not real.
Takata recall - I have never been contacted by bmw regarding this recall. I have no idea if my airbags are faulty or not. I have called my dealer and they said that I would receive a letter if/when they were able to repair the airbags. Have never heard from them.

This delay of acceleration has caused many close calls for accidents and/or sudden braking needed because of over acceleration. Between my research on this issue and experiences with this, I can reliably reproduce this issue.
