What Happened
The ABS system in your vehicle uses sensors to prevent wheels from locking up during hard braking. In certain conditions, the sensor on your truck or SUV might get corroded, causing the ABS to activate unnecessarily.
Risk if Unfixed
If this happens, you could experience longer stopping distances, especially when braking at low speeds. This could lead to a crash, especially in situations where you need to stop quickly, like on a wet or snowy road.
Free Fix
Your authorized dealer will clean and protect the wheel speed sensor, and make sure it's working properly. They'll also check the sensor's signal to make sure it's sending accurate information. This service is free of charge.
