What NHTSA recorded

A gasket was mistakenly placed between the brake master cylinder and the power boost which prevented the two parts from fitting together properly. Damage may have resulted to the mounting ears of the master cylinder and the hydro-boost. This condition could lead to brake failure.

Remedy

The dealer will install a new brake master cylinder and hydro-boost unit, free of charge, on all affected vehicles.
