Defect & Vehicles Involved, Owner Notification, Campaign Responsibility & Parts Information

DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1988 Chevrolet Corvette model vehicles equipped with 17 inch wheels. The weld attaching the wheel center to the rim may be missing on a small number of wheels. Lateral forces during a cornering maneuver could cause the wheel center to separate from the rim. Also, a brake reaction could cause rotation of the wheel center relative to the rim. These conditions can result in partial loss of steering control and brakes, loss of tire air pressure and sudden change in vehicle direction, which could result in a vehicle crash without prior warning.
DEFECT INVOLVED (CONT'D)

To prevent this condition from occurring, it will be necessary to inspect all wheels on involved vehicles for the presence of a weld. Wheels found with missing welds must be replaced.
