What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2015 BMW M3, 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.

Each component in detail
What the reports in each category say, in the owners' own words
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
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

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
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.
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
