Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I had a recent problem with our 525i. I was driving it and it lost power/died. When the vehicle died, I lost power steering and power brakes. The car would not restart and no error lights or messages were displayed on the idrive. I had the car towed home. After the initial check of the vehicle, it showed the crank sensor fault. I noticed a bunch of metal throw off in the oil filter and the vehicle did not have compression in cylinder 2 and 6. I was thinking catastrophic engine failure. …”

NHTSA complaint #10415426, filed 2011-07, 85,047 miles

“Since purchasing the vehicle (10/12/2005) the vehicle alerts us that the oil level is low - do not continue to operate vehicle. The car was serviced each time the problem occurred by south bay Bmw. Reprogramming, sensors and oil consumption tests have been done; however, whatever repairs are done, the problem recurs.”
