What Happened
The rear brake caliper in your vehicle is a metal piece that helps slow down your car when you press the brake pedal. In some 2018-2019 models, the coating on this part might be too thin, causing air pockets to form and reducing the effectiveness of your rear brakes.
Risk if Unfixed
If your rear brakes don't work as well as they should, you could lose some stopping power, which increases the risk of a crash, especially on the highway or during emergency stops.
Free Fix
Your dealer will bleed your vehicle's brake system to remove any air pockets and ensure your brakes work properly – and this service is free of charge. You'll receive a notification when the repair is ready to be scheduled.
