Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My Bmw 745I 2003 has experience several area of oil leakage. When brought in to the dealer, I'm told that it's due to the engine cooling error. I found this website with the recall of the same model and year Bmw for this very reason but I am told by my dealer and the manufacturing company that my VIN # is not on the list of recalls. How can this be possible when the recall is for the same year and model.”
