BMW North America is recalling 72 model year 2016 BMW M2 Coupes, 2015-2017 M3 Sedans and 2015-2016 M4 Coupes and M4 Convertibles.
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.
Loose rear sub-frame bolts may adversely affect vehicle handling and control, increasing the risk of a crash.
What to do
BMW will notify owners, and dealers will replace the rear sub-frame bolts with new bolts, free of charge. The recall is expected to begin October 24, 2016.
Owners may contact BMW customer service at 1-800-525-7417.
