What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1990 BMW 735I, 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.

THIS MUSTARD COLORED MODULE CAUSES THE COMPUTER TO WARN THE DRIVER OF A FAILED PARKING LIGHT AND/OR TAIL LIGHT WHEN THE HEADLIGHTS ARE TURNED ON. EVERY TIME THESE LIGHTS ARE TURNED ON, THIS MODULE SENDS A SIGNAL TO THE DRIVER. UPON INSPECTING THE LIGHTS WHEN THIS WARNING OCCURS, THE LIGHTS ARE FULLY FUNCTIONAL. HOWEVER, ABOUT ONE THIRD OF THE TIME THESE LIGHTS (THE FRONT LEFT PARKING LIGHT, THE REAR LEFT PARKING LIGHT, AND THE RIGHT REAR MARKER LIGHT IN THE BUMPER) ACTAULLY FAIL. THESE LIGHTS FAIL EVEN THOUGH THEIR FILLAMENTS ARE STILL GOOD. WHAT IS CAUSING THIS PROBLEM IS A CRACKED SOLDER JOINT INSIDE OF THIS MUSTARD COLORED RELAY. *AK
