In the US, there were recalls for the knee airbag which may not deploy properly, passenger airbag which is manufactured incorrectly, and the crankshaft position sensor firmware which may cause the engine to stall. Few reports on iDrive system not functioning, warning from Tire Pressure Monitoring System, Headlight malfunction error, and AC not blowing consistently through all vents. Few M4 owners had issue with wastegate short circuit leading to turbo failure.
