What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1991 BMW 525I, 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.

WHILE SITTING IN MY 1991 BMW 525I THE SEAT SUDDENLY FELL BACKWARD,AND SIDEWAYS. AFTER REMOVING THE SEAT, AND ALMOST COMPLETELY DISSASSEMBLING IT SO I COULD TRY TO REALIGN THE THING LONG ENOGH TO MAKE IT HOME,I WAS ABLE TO THROUGH BRUTE FORCE PUT IT BACK IN PLACE.

THE PLASTIC THROUGH TIME WEARS AND STRETCHES UNTILL THE DRIVE CABLE SLIPS OUT OF GEARBOX ALLOWING CATASTROPHIC FAILURE. I JUST CHECKED TO SEE IF THIS ITEM HAD BEEN RECALLED WITH NO LUCK. *AK

THE SPEEDOMETER OPERATES IRRATICALLY DURING COLD WEATHER. IT FUNCTIONS OK WHEN WARM. THIS IS CAUSED BY BAD MATERIALS USED ON THE SPEEDOMETER PCB BOARD. A NUMBER OF BMW OWNERS HAVE EXPERIENCED THIS PROBLEM AND FIXES ARE SUGGESTED ON THE INTERNET AT THE FOLLOWING LINKS. HTTP://WWW.ESKIMO.COM/~DALUS/BMW/SPEEDO/SPEEDO.HTM AND AT HTTP://WWW.ESKIMO.COM/~DALUS/BMW/E30/INTERIOR/E30_SPEEDO_SENDER_PROBLEM.HTML. UNRELIABLE OR LACK OF INDICATION OF DRIVING SPEED CAN BE A SERIOUS SAFETY ISSUE. THIS APPEARS TO BE A PROBLEM THAT MANY BMW OWNERS HAVE SUFFERED AS INDICATED BY THE NUMBER OF PEOPLE WHO HAVE REPORTED IT ON THE WEB. THE DEALER WANTS OVER $600 TO FIX THE PROBLEM. *MJS
