Known issues on the 1997 Bonneville. A seat trim problem accounts for the 1 recall on the 1997 Bonneville. On certain 1997 Bonneville vehicles, 47 in number, the seat cover material failed the federal flammability standard for interior materials, so an ignition source could start a fire in the cabin. Dealers recovered the front seat backs and the rear seat cushion and back.
