DETROIT (AP) — General Motors is recalling more than 473,000 trucks and SUVs in the U.S. and Canada because the brake pedals can come loose and fail to work properly.

The recall covers certain 2015 and 2016 Chevrolet Silverado HD, GMC Sierra HD and Chevrolet Tahoe police vehicles.

GM says a nut on the brake pedal pivot mechanism can come loose, causing the pedal to loosen and possibly become inoperative.

The company says it has no reports of crashes or injuries due to the problem.

GM says the recall should begin shortly.

Toyota’s youth-oriented Scion brand is recalling about 28,000 FR-S sports cars in North America because drivers can take the keys out of the ignition without the car being in park.

The recall covers cars with automatic transmissions from the 2013 through 2016 model years.

Toyota says in some cases, the mechanism that holds the key until the ignition unless the cars are in park may not have been connected before delivery. That makes it possible to remove the key while the cars are in gear, which could increase the risk of cars rolling away unexpectedly.

Toyota wouldn’t say if the problem has caused any crashes or injuries. The company says dealers will check the key lock mechanism. If it doesn’t work, they’ll activate it.
