What Happened
The brake system in your vehicle has a small valve that helps control the brake fluid. In some cases, this valve's housing might not meet the proper specifications, which could lead to a problem with the valve's seal.
Risk if Unfixed
If the seal breaks, you might feel a slight increase in steering effort while braking or parking. This could also make it slightly harder to slow down, especially on hills or when stopping suddenly.
Free Fix
Your dealer will replace the faulty valve with a new one at no charge to you. You should schedule the repair as soon as you get the recall notice, and contact the manufacturer's hotline for more information.
