Hydro-Boost Relief Valve May Not Function Properly

The hydro-boost housing relief valve bore may be out of specification. The seal may fracture as a result, which may reduce braking assist and slightly increase the steering effort while braking. Under certain conditions, more braking effort will be required to stop the vehicle. Dealers will replace the hydro-boost relief valve. The recall began June 18, 2004. The GM recall number is 04004.

Fuel Tank May Leak in a Crash

In 30 degree left angle frontal crash conditions with a severe enough impact, the fuel tank may be punctured by a torn mid-frame cross member. A fuel leak in the presence of an ignition source may result in a fire. Dealers will install a fuel tank shield. The recall began February 20, 2003. The GM recall number is 03002.

Some Door Welds May Not Be to Specification

On 107 vehicles, one or two welds on the rear door upper hinge may not be to specification. This may cause the door strength to be reduced in a side impact crash. Dealers will inspect the welds and install a bolt to secure the hinge if any are found to be out of specification.
