Brakes
Loose caliper bolts may cause reduced braking performance and result in lengthened stopping distances, increasing the risk of a crash.
The bolts that secure the rear brake calipers may not have been tightened properly. Dealers will inspect the bolts on both rear caliper brackets and tighten any that are loose free of charge to resolve the concern.
General Motors notified owners of affected vehicles starting in 2013. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them. The General Motors recall number is 13247.
