Dealers will fix the problem with a software update, free of charge. Curiously, both cars are capable of receiving over-the-air software updates. But the companies are asking owners to bring the cars in for the patch.
Until owners have the chance to bring the car in for repair, both companies recommend they avoid parking on inclines.
Recall repairs are always free. Manufacturers attempt to contact every owner, but they don’t always reach them all with the news. Find out if your car has ever been recalled at our recall center.
