On certain vehicles, a varistor in the Occupant Classification System (OCS) control unit located in the passenger seat cushion may have been manufactured incorrectly. Under certain conditions, this could cause an interruption of signal between the OCS and the Airbag control unit (ACU). This could result in the passenger airbag being suppressed. The (red) supplemental airbag warning light would flash & the (amber) front passenger airbag status light would illuminate to alert the vehicle operator, however in case of a crash a suppressed airbag could result in personal injury or death. Correction: Dealers will test the signal between the OCS & ACU and if necessary will replace the seat cushion containing OCS hardware.
On certain vehicles, the fuel filler hose may crack from exposure to ozone. This could cause fuel leakage from the hose while refuelling and the Malfunction Indicator Light (MIL) to illuminate as a result of the onboard diagnostic system detecting a leak in the evaporative emission control system. Fuel leakage, in the presence of an ignition source, could result in a fire. Correction: Dealers will replace the fuel filler hose.
On certain vehicles, the circuit board for the crank position sensor may have an improper solder joint. This could cause the Service Engine Soon warning light to come on, create a no start condition, cause reduced engine power, or cause the engine to stop running without warning during vehicle operation. Correction: Dealers will replace the crankshaft position sensor and both camshaft position sensors.
