CAMPAIGN: REAR BENCH SEAT STRENGTH (REINFORCEMENT ADDED)

Models: 1989-90 G-Vans with AQ3 or AQ4 Seating

General Motors of Canada has determined that the seat backs of all the rear bench seats in certain 1989-90 G-Vans may not meet the strength requirements of CMVSR 207, "Anchorage of Seats - Passenger Cars, Multi-Purpose Passenger Vehicles, Trucks and Buses." Should one of these vehicles become involved in an accident and there were passengers in the seat, the seat back frame could break and suddenly recline without supporting the loading specified in the Canadian standard. This could increase the likelihood of occupant injury.

In order to comply with CMVSR 207, and to correct this condition, reinforcements will be added that run from the side of the seat back frame assembly to the seat cushion frame assembly to strengthen the seat back.

VEHICLES INVOLVED:

Involved are certain 1989-90 G-Vans built within the following VIN breakpoints:

Model Year Plant Carline From Through ---------- ---------- --------- -------- -------- 1989 Scarborough GMC K4501016 K4529091 Chevrolet K4103092 K4165752
