If we had a penny for every vehicle recalled so far this week, we’d buy all of our loyal readers an ice cream cone. Okay, maybe not, but that doesn’t mean there hasn’t been an overabundance of recalls lately. And we can add one more company to that list: BMW.

BMW announced today that it is voluntarily recalling 156,137 vehicles for potentially loose bolts in the six-cylinder engine that, if broken, could cause stalling or engine failure, Reuters reports.

BMW says that in rare cases, the bolts holding the variable camshaft timing unit can come loose or break, causing the engine to go into a “safe mode.” If the issue persists, it can lead to engine damage.

The recall affects the 2010 to 2012 model year 1 Series, 3 Series, 5 Series, 5 Series Gran Turismo, 6 Series, X3 Crossover, X5 Crossover, X6 Crossover and Z4 sports car.

Drivers of potentially affected vehicles may continue to drive, but officials caution that if a “check engine” or “service engine soon” light appears they should contact their nearest BMW center immediately.

In 2012, BMW recalled 1.3 million 5- and 6-Series vehicles because of a problem with a battery cable cover that could lead to a fire. It wasn’t clear if the issue had resulted in any crashes or injuries.

BMW is the third major automaker to announce this week bringing the total of affected cars in the U.S. to more than 6.9 million.

On Monday, Ford issued two recalls affecting 435,000 vehicles for possible steering issues and unsafe seat frames.

Toyota recalled 6.4 million vehicles on Wednesday for a number of issues including problems with seat rails, airbag deployment and steering columns.
