Campaign - Unexpected Hood Opening
9218oldsmobile02
Number: 92-C-03
Date: October 1991
Section: 10-5
Subject:
UNEXPECTED HOOD OPENING
Models/Years:
CERTAIN 1991 AND
1992 CUSTOM CRUISER
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1991 and 1992 Oldsmobile Custom Cruiser model vehicles. The secondary hood latch assemblies in these vehicles can corrode causing a very high latch release effort and possibly preventing the hood from latching properly when it is closed.
If the secondary hood latch is not properly engaged and the primary hood latch was also not engaged, the hood could open unexpectedly. If this were to occur while the vehicle was in motion, the hood may contact the windshield, reducing the forward vision area of the driver, and a vehicle crash without prior warning could result.
To prevent this condition from occurring, dealers are to install a new secondary hood latch assembly with improved corrosion resistance.
VEHICLES INVOLVED
Involved are certain 1991 and 1992 Oldsmobile Custom Cruiser station wagons within the breakpoints listed below:
