DETROIT » General Motors Co. is recalling more than 27,000 Cadillac SUVs worldwide because the wheels can fall off.

The company says the recall affects the 2013 Cadillac SRX with 18-inch wheels. Canadian safety regulators say the wheel nuts may not have been tightened enough at the factory.

GM says the problem hasn’t caused any crashes or injuries, and no wheels have fallen from vehicles.

Dealers will rotate tires and tighten the nuts at no cost to the owners.

The recall affects almost 19,000 SUVs in the U.S. and another 913 in Canada. The rest were exported to other countries.
