What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2001 BMW 540IA, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

TL* THE CONTACT OWNS A 2001 BMW 540IA. THE CONTACT STATED THAT THE RECALL NOTIFICATION FOR NHTSA CAMPAIGN NUMBER: 17V047000 (AIR BAGS) WAS RECEIVED IN JANUARY OF 2017. AFTER TAKING THE VEHICLE TO THE DEALER THE CONTACT WAS INFORMED THAT THE AIR BAG INFLATOR WAS PREVIOUSLY REPLACED IN 2006 AND DID NOT REQUIRE ANOTHER REPLACEMENT. AFTER READING THE SUMMARY FOR THE RECALL THE CONTACT DISCOVERED THAT IF THE AIR BAG INFLATOR WAS PREVIOUSLY REPLACED DUE TO A CRASH OR AS A RECALL REMEDY, THE REPLACEMENT AIR BAG INFLATOR MAY ALSO EXPERIENCE A FAILURE AND NEEDED TO BE REPLACED A SECOND TIME. THE CONTACT THEN NOTIFIED THE MANUFACTURER AND WAS ALSO INFORMED THAT THE VEHICLE WOULD NOT BE ELIGIBLE FOR A SECOND REPLACEMENT INFLATOR ALTHOUGH THE VIN ASSOCIATED WITH THE VEHICLE INDICATED THE RECALL WAS OUTSTANDING. THERE WAS NO FAILURE MILEAGE.

I HAVE A 2001 BMW 540IA [XXX] AND ALL THE EXTERNAL LIGHTS ARE GRADUALLY FAILING. IN ALL CASES THE LIGHTS BULBS ARE OK. FIRST THE PASSENGER SIDE REAR TURN SIGNAL LIGHT FAILED, THEN THE DRIVERS SIDE DAYLIGHT RUNNING LIGHT, THEN THE PASSENGER SIDE REVERSING LIGHT, THEN THE PASSENGER SIDE BRAKE LIGHT, THEN DRIVERS SIDE HIGH BEAM, THEN THE DRIVERS SIDE FRONT TURN LIGHT ETC. FAILURES WERE OVER APPROXIMATELY A 2 WEEK PERIOD. THE MOST DISTURBING THING IS THE ONBOARD COMPUTER IS SHOWING ALL THE EXTERNAL LIGHTS WORKING CORRECTLY. MY BMW MECHANIC TELLS ME THE FAULT IS IN THE ONBOARD LIGHT CONTROL MODULE (LCM). I CONSIDER A FAILURE OF THIS NATURE TO BE COMPLETELY UNACCEPTABLE IN A 4 YEAR OLD VEHICLE AND A SERIOUS SAFETY DEFECT THAT HAS THE POTENTIAL TO RESULT IN AN ACCIDENT. I HAVE REPORTED THE PROBLEM TO BMW NA, SO FAR THEY ARE NOT INTERESTED IN INVESTIGATING THE PROBLEM. *NM UPDATED 07/18/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
