DEFECT: On certain sport utility vehicles, the ignition system wiring harness is routed under the intake manifold. The harness can rub against the manifold during vehicle operation and abrasion damage to the harness can occur. Damage to the wiring harness can cause a short in the ignition circuit, which can cause the ignition fuse to blow and the engine to stall. This can result in a loss of control of the vehicle and could cause a crash.
REMEDY: Dealers will repair any wiring harness damage and will add additional insulation and a protector plate to prevent the wiring harness from becoming damaged. The manufacturer has reported that owner notification began on December 16, 2003. Owners may contact Suzuki at 1-800-934-0934.
