Open the full vehicle complaint log (all categories)BMW HAS ACKNOWLEDGED A KNOWN ISSUE CAUSING FAILURE OF THE HIGH PRESSURE FUEL PUMP. THE BMW TECHNICAL BULLETIN IS (SI B 13 03 09). THIS EXTENDS THE WARRANTY OF THE PART TO 10 YEARS. THE PROBLEM IS THAT THE FAILURE IS NOT WELL DOCUMENTED BY THE VEHICLE ISSUE LOGGING SYSTEM, AND THAT OTHER ISSUES WITH THE CAR ARE CITED AS A REASON TO NOT PERFORM THE PART REPLACEMENT. BMW N. AMERICA AND BMW OF AUSTIN DO NOT, AND CAN NOT PROVIDE A TEST TO CHECK THE VEHICLE'S FUEL SYSTEM INDEPENDENTLY. THIS PUTS DRIVERS, PASSENGERS AND ANYONE ELSE AT RISK SHOULD THE PART FAIL SUDDENLY AFTER EXHIBITING PARTIAL FAILURES. THE COMPLAINT SHOULD ALSO NOTE THAT BMW DOES NOT PROVIDE AN EASY WAY TO REPORT THIS IMPORTANT SAFETY ISSUE AS THERE IS NO FIXED PROCESS TO DOCUMENT THE ISSUES.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
