NHTSA overall safety rating
Not ratedNHTSA has no overall rating for this year
NHTSA's VIN data lists no trims for the 2015 M, so these are the versions EPA tested, by its names. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 19 complaints with NHTSA about the 2015 M. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 6 recall campaigns for the 2015 M over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
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.
Risk: 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.
BMW of North America, LLC (BMW) is recalling certain 2014-2019 M6 Gran Coupe vehicles. The third brake light may become loose, possibly allowing the light to detach from the vehicle.
Risk: If the third brake light detaches from the vehicle, it would no longer provide the required lighting to following traffic, or it may become a road hazard, increasing the risk of a crash.
Remedy: BMW will notify owners, and dealers will inspect the third brake light and properly secure it with new fasteners. If the third brake light detached from the vehicle and is damaged, it will be replaced. All repairs will be performed free of charge. The recall began April 17, 2020. Owners may contact BMW customer service at 1-800-525-7417.
BMW of North America, LLC. (BMW) is recalling certain 2015-2019 X6 sDrive35i, X6 xDrive35i, X6 xDrive50i, and X6M vehicles equipped with rear seat lower anchor bars used in securing child restraint seats. The lower anchor bars may become damaged over time when used with an ISOFIX-type, rigid-style connector, child restraint system.
Risk: Damaged lower anchor bars may increase the child's risk of injury in the event of a crash.
Remedy: BMW will notify owners, and dealers will weld a reinforcing bracket to the lower anchor bars and the vehicle body, free of charge. Owner notification began January 17, 2020. Owners may contact BMW customer service at 1-800-525-7417.
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.
Risk: 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 BMW M5 sedans manufactured September 4, 2014, through December 4, 2014, 2015 M6 coupes manufactured September 3, 2014, through December 3, 2014, 2015 M6 convertibles manufactured September 8, 2014, through December 4, 2014, and 2015 M6 Gran Coupe vehicles manufactured September3, 2014, through December 4, 2014. The affected vehicles have a driveshaft that may have been inadequately welded during manufacturing.
Risk: Due to the improper weld, the driveshaft may fracture and fail, causing loss of drive to the rear wheels and a loss of propulsion. Additionally, if the car is turned off and exited without the parking brake applied, the car may roll. Either condition increases the risk of a crash.
Remedy: BMW will notify owners, and dealers will inspect and replace the driveshaft, as necessary, free of charge. The recall is expected to begin during September 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.
Risk: 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.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
