“Fourth incident - on-board diagnostics indicate malfunction passenger restraint system in eleven months for same problem. Service yet to be scheduled with dealer. I know there was recall for same problem in 2006 for Bmw 3-series. I think Bmw is installing faulty seat mats.”

NHTSA complaint #10466956, filed 2012-07, 74,000 miles

“Vehicle is not allowed recall since VIN# does not apply however all things wrong with vehicle are exactly what can be found under recalls: NHTSA campaign id numbers 12e029000,09v257000, 09v257000. Bmw fairfax and Bmw north america state recall cannot be processed because my VIN does not apply. It is bothersome to know that I am experiencing only these 3 problems that so happen to be the only errors and all 3 are on the recall list for my make, model, and year. …”
