NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2015 BMW M3. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
Fuel tank top weld has failed, and is actively leaking fuel. This is likely to cause ignition of the vehicle during use and poses a threat to the lives of passengers and other drivers on the road as well as emissions failure. The failed weld was confirmed by independent Bmw technician. This part is a known failure point, and emission extended warrantee has been established for identical cars of the given make/model/year. The car has limited miles, no structural or cosmetic damage causing this failure. The car is not drivable as it poses a threat to safety.
Gas tank has a significant leak. This allows for the opportunity to ignite the car putting all persons lives in danger, and effects emissions. Problem has been confirmed by independent Indy shop technician
REAR VIEW CAMERA STOPPED WORKING, SCREEN DISPLAYS "NO SIGNAL". FUSE DID NOT BLOW.
CRANK HUB SPUN TIMING SPROCKET CAUSING VALVES TO IMPACT PISTON AND CATASTROPHIC ENGINE FAILURE. QUOTED MORE THAN $10K OUT OF POCKET TO REPAIR. THIS IS CAUSED DUE TO POOR CRANK HUB DESIGN. CAR COMPANIES HAVE BEEN USING KEYED CRANKHUBS FOR GENERATIONS BUT BMW DECIDED TO NOT USED A KEYED HUB.. THIS IS VERY NEGLIGENT CONSIDERING HOW MANY OF THESE VEHICLES HAVE ENGINE FAILURE DUE TO THIS.
