Recalls

1 vehicle recall from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Brakes (hydraulic) Vehicle recall #10V499000 · 2010 · 728,544 vehicles

What's wrong: Brake fluid containing polymers is used that acts as lubricants for certain brake system components. If replacement brake fluid is used that does not contain such polymers, or that contains only small amounts, a part of the rubber seal located at the rear of the brake master cylinder May become dry, and the seal May curl during movement of the piston. If this occurs, a small amount of brake fluid could slowly leak…

Why it matters: A leak of brake fluid could lead to a change in brake pedal feel and overtime a degradation in braking performance increasing the risk of a crash.

The fix: Dealers will replace the seal with a newly designed one. This service will be performed free of charge. The safety recall began on November 15, 2010.
