Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 2015 BMW M4. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
BMW North America, LLC (BMW) is recalling certain model year 2016 BMW M2 Coupe vehicles, 2015-2017 M3 Sedan vehicles and 2015-2016 M4 Coupe and M4 Convertible vehicles. During servicing of the rear differential for a prior service action, the rear sub-frame bolts may have been reused instead of being replaced. Reuse of the existing bolts may cause the bolts to loosen.
Consequence
Loose rear sub-frame bolts may adversely affect vehicle handling and control, increasing the risk of a crash.
Remedy
BMW will notify owners, and dealers will replace the rear sub-frame bolts with new bolts, free of charge. The recall began on November 3, 2016. Owners may contact BMW customer service at 1-800-525-7417.
BMW of North America, LLC (BMW) is recalling certain model year 2015-2016 M3 Sedan vehicles manufactured May 30, 2015, to September 2, 2015, 2016 M4 Coupe vehicles manufactured July 3, 2015, to September 11, 2015, and 2015-2016 M4 Convertible vehicles manufactured May 29, 2015, to August 4, 2015. The affected vehicles have a driveshaft with a slip-joint that may not have been filled with grease. As a result, the slip-joint may fail over time.
Consequence
If the slip-joint fails, there would be a loss of power to the rear axle and therefore the vehicle would stop moving, increasing the risk of a crash.
Remedy
BMW will notify owners, and dealers will inspect the driveshaft, replacing it as necessary, free of charge. The recall began on January 14, 2016. Owners may contact BMW customer service at 1-800-525-7417.
BMW of North America, LLC (BMW) is recalling certain 2014-2015 2 Series Coupe (228i, 228i xDrive, M235i), 3 Series Sedan (320i, 320i xDrive, 328i, 328i xDrive, 335i, 335i xDrive, M3, 328d, 328d xDrive), 4 Series Coupe (428i, 428i xDrive, 435i, 435i xDrive, M4), and 2015 4 Series Gran Coupe (428i, 428i xDrive, 435i, 435i xDrive) vehicles. The head air bag inflator may fail at the weld joint, which can cause gas to leak from the inflator or result in an inflator rupture.
Consequence
An inflator that ruptures may cause sharp metal fragments to enter or exit the vehicle, increasing the risk of injury. Additionally, an inflator that leaks gas may only partially inflate during a crash, increasing the risk of injury.
Remedy
Dealers will replace the head air bags, free of charge. Owner notification letters were mailed November 4, 2024. Owners may contact BMW customer service at 1-800-525-7417.

Complaints across nearby BMW M4 model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.
VERIFIED EMPTY IMPORT SNAPSHOT
No exact NHTSA ODI investigation row was matched.
