What Happened
The electronic brake boost system in your vehicle is like a computer that helps you slow down and stop with less effort. It's connected to a sensor that talks to the system electronically, but in some 2020-2021 models, that connection can get dirty and cause problems.
Risk if Unfixed
If the sensor and brake boost system can't communicate, you'll need to push the brake pedal much harder to slow down and stop. This could make it harder to control your vehicle, especially on slippery roads, and increase the risk of a crash.
Free Fix
Your dealer will replace the electronic brake boost module with a new one, free of charge. This will ensure your brake system works smoothly and safely. You should schedule the repair as soon as you get the recall notice.
