NHTSA Complaint #10491620 — 2004 BMW 325I

THE DRIVER SIDE MIRROR WILL NOT MAINTAIN IT'S SET POSITION. ON MY CAR THE MIRROR WOULD CHANGE POSITION EVERY MINUTE. THIS CONTINUED ALL DAY AND NIGHT FOR THREE DAYS. THIS MADE LANE CHANGES, ENTERING A LANE, OR TURNING. VERY DANGEROUS AND DIFFICULT. I IMMEDIATELY ACCOUNTED FOR MY MIRROR NOT BEING USABLE AND PLOTTED MY LANES CHANGES AND DRIVING LANES AHEAD OF TIME. THIS IS A PROBLEM THAT CAN HAPPEN IMMEDIATELY WITHOUT WARNING. I COULD ENDANGER A DRIVER NEEDING TO CHANGE LANES, WHEN THEY LOOK OVER AND HAVE NO MIRROR, OR IS FACED WITH A MIRROR THAT WILL NOT HOLD POSITION. THIS IS A SERIOUS SAFETY ISSUE. ===================EXAMPLES BMW BULLETIN ==LINK PROVIDED UPON REQUEST===== SI B51 36 08 BODY EQUIPMENT APRIL 2009 TECHNICAL SERVICE THIS SERVICE INFORMATION BULLETIN SUPERSEDES SI B51 36 08 DATED FEBRUARY 2009.

THE UNEXPECTED RESISTANCE VALUE IS CAUSED BY ONE OF THE FOLLOWING: * CORROSION ON THE LIN-BUS CONNECTION AT THE MIRROR, SWITCH BLOCK, OR FRM * POOR CONNECTION AT THE MIRROR, SWITCH BLOCK, OR FRM * DAMAGED MIRROR ELECTRONICS. *TR
