Power Brake Assist Fails

Recall Details

A vacuum line fitting to the power brake booster may fracture, causing loss of power assist to the brake system. Dealers will replace the connector end fitting at the brake booster free of charge to resolve the concern.

Our Quick Take

The system that provides power assist to vehicle braking may fail due to a broken vacuum line fitting. This could make it more difficult to stop a vehicle, and could result in a crash.
