NHTSA complaint #708415, filed 1999-07

“Problem: brake pedal goes to floor-no pressure, no braking. Near miss collisions. Master cylinder, ABS computer, have been replaced, brakes have been replaced as requried---this vehicle has a definate brake history problem. Apparently, based on internet articles I've researched I'm not alone. I'm extremely concerned for the safety of my wife and 3 small children. We're basically afraid to drive this vehicle.! When the brakes go down to the floorboard without any pressure, there's obviously something wrong with the brake system---------even the guy at the car wash was scared!”

NHTSA complaint #746579, filed 2001-06

“This car has been in the shop (pohanka Chevrolet in va) 25, yes, 25 times since 1994. I have now just had to replace the second computer system in 2 years. I will be glad to provide documentation of the number of visits to the dealer as well as the expensive costs I have incurred. Has there been significnat problems with this vehicle and what recalls (other than windshield motor and one other recall). My mechanic feels that chvroloet may be aware of the computer problems in this car becasue of its urgent requirement to send back the coil of the original.”
