The 2011 BMW 1 Series has 3 recalls, with the most serious risks including a rear driveshaft CV joint that can break and cut power to the wheels, a seatbelt pretensioner that can ignite during a crash, and an engine that can stall without warning.
On the drivetrain side, the CV joint connecting the rear driveshaft can fail over time, leaving the vehicle without propulsion. The seatbelt concern involves the front pretensioner: in a significant crash, insulation around the pretensioner can catch fire when it deploys. The engine recall involves bolts in the variable valve timing system that can come loose or break, causing the engine to stall while driving.
