What Happened
The anti-lock braking system (ABS) in your vehicle relies on speed sensors to work properly. In certain areas with high salt levels, these sensors can get corroded and send false signals.
Risk if Unfixed
If the ABS system gets confused, you'll experience longer stopping distances during slow-speed braking, which could lead to a crash.
Free Fix
Your authorized dealer will clean and protect the speed sensor, replace the wheel speed sensor if needed, and check its signal to ensure it's working correctly — all at no cost to you.
