BMW Canada has recalled more than half the vehicles it sold between 2006 and 2011 to address faults that could cause the cars and SUVs to burn.

Two recent recall campaigns affect more than 80,000 vehicles from those six model years, during which time the German automaker retailed about 149,000 sedans, station wagons, and SUVs.

The first recall is to fix the heater in the positive crankcase ventilation (PCV) valve, which could overheat and catch fire. The PCV valve is a device that prevents the engine from becoming pressurized internally, which would cause oil leaks and other issues. The heater’s job is to keep the valve warm in wintertime so it doesn’t freeze shut.

This campaign covers 3 Series, 5 Series, X3, and Z4 models from 2007 to 2011; 1 Series cars from 2008 to 2011; and X5 SUVs from 2007 to 2010.

Recall number two looks after 3 Series models sold between 2006 and 2011. In these sedans and wagons, wiring for the heating and air conditioning system can overheat, causing connectors and insulation to melt. That’s a condition that could cause a short circuit and start a fire, even when the vehicle is turned off and parked.

In both cases, BMW is recommending the cars be parked outside until they’ve been fixed in order to avoid causing a garage or house fire.
