Summary
The BMW 1 Series has 6 recalls covering 2007 through 2011 model years, with the most serious being a seatbelt pretensioner issue on 2008-2011 vehicles where the insulation around the front pretensioner can ignite during a crash severe enough to deploy it, creating a fire risk inside the cabin.
The 2010 model year has a separate engine concern where bolts securing the variable camshaft timing unit can loosen or break, causing the camshaft to lose proper adjustment and the engine to either drop into reduced power mode or stall without warning while driving. The 2011 model year has a rear driveshaft CV joint whose rivet connections can weaken over time and eventually break, cutting drive power to the wheels. On 2008 models, incorrectly crimped connectors on the side airbag and seatbelt tensioner wiring can lose contact, which may prevent the airbags or tensioners from functioning in a crash. There is also a blower motor regulator connector on 2008 vehicles that can corrode, causing the wiring to overheat, melt, and potentially catch fire; drivers may notice a blower that stops working, a burning smell, or smoke before this occurs. Going back to the 2007 model year, sound insulation in the B-pillar near the seatbelt pretensioner can ignite if the pretensioner fires in a crash, adding to fire and injury risk in an already serious collision.
