NHTSA complaint #10069118, filed 2004-01, 52,000 miles

“1998 Chevrolet Silverado pick-up had what appeared to be radiator leak. After further diagnosis, what was actually the problem was that the fitting in the intake manifold used to connect the coolant hose was made of a different metal than the intake manifold; the part crumbled while trying to fit the coolant hose over the fitting by hand (no tools involved!). I now have a truck in the garage that I cannot drive until it is fixed because the part does not fit due to the corrosion where the dissimilar metals came into contact and corroded. …”

“Intake manifold gasket was cracked and leaked out all water and severely overheated engine. The mechanic here at work says that he has changed a few hundred of these here at work were we have thousands of chevy trucks that are this same engine.”

“Intake manifold leaked coolant onto the engine. This can result in the engine overheating and result in a fire. The fitting in the intake manifold used to connect the coolant hose was made of a different metal than the intake manifold itself. This caused dissimilar metal corrosion in the fitting itself which lead to unnoticed pin hole leaks in the cooling system. Consumer felt GM should have provided a barrier between the two metals to solve the problem.”

NHTSA complaint #10022593, filed 2003-09, 60,000 miles

“The contact stated while applying brake pressure at low speeds the anti-lock brakes activate, which made the vehicle difficult to stop. This occurred intermittently on dry roads during normal braking without warning. The vehicle was taken to an independent repair shop. The mechanic replaced the front brake pads, which did not remedy the problem. The dealership and manufacturer were not alerted. The mechanic installed a serpentine belt. Updated 03/09/06.”
