CAMPAIGN-REVISED: SECONDARY HOOD LATCH/INSTALL SKID PLATE

Model and Year: 1987 CHEVROLET CORSICA AND BERETTA MODELS

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1987 Chevrolet Corsica and Beretta model vehicles. These vehicles are part of a product exposure program developed by Chevrolet. All vehicles are owned by General Motors Acceptance Corporation and leased to dealers or daily rental fleets. These vehicles mav have been produced with a secondary hood latch that may contact the support bracket. This condition can prevent proper engagement of the secondary latch. Additionally, the secondary latch can contact the primary latch return spring predisposing it to disengage.

If the secondary hood latch were not properly engaged and the primary latch were to disengage, the hood could unexpectedly open. If this were to occur while the vehicle was in motion, the hood may contact the windshield, re- ducing the forward vision area of the driver and a vehicle crash could occur without prior warning.

Correction of this condition will consist of installation of a secondary latch skid plate in both Corisica and Beretta models. Additionally, for Beretta models only, a revised secondary latch assembly will be installed.

VEHICLES INVOLVED

Involved are all 1987 Corsica and Beretta models produced within the following Vehicle Identification Number (VIN) breakpoints:
