# CAMPAIGN:HOOD OPENING INSPECT AND REPLACE LATCH

#### Models: 1985-86 Oldsmobile Calais

General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in some 1985 and 1986 Oldsmobile Calais models. The secondary hood latch may be incorrectly aligned and/or may exhibit a binding condition of the latch pivot. Either of these conditions could prevent adequate engagement of the secondary hood latch to the front end support when the hood is in the closed position. In addition, the primary hood latch "pop-up" lever may be mispositioned. This could cause the hood to appear closed without being cumpetely latched.

If the secondary hood latch is incorrectly aligned and/or is binding at the latch pivot, and the primary hood latch is not completely engaged to the hood, the hood could unexpectedly open while the vehicle is in motion. Should this occur, the hood may contact the vehicle windshield reducing the forward vision area of the driver, and a vehicle crash without prior warning could occur.

To prevent the possibility of this condition occurrinq on vehicles involved, Dealers are to replace the secondary hood latch and inspect the primary hood latch pop-up lever for correct alignment and function and, if necessary, align the pop-up lever or replace the primary hood latch as described in the Service Procedure of this Bulletin.
