On certain vehicles, a fault in the Electric Power Steering (EPS) system could result in an immediate loss of power steering assist without warning to the driver. This would unexpectedly increase the steering effort force necessary to steer the vehicle at lower vehicle speeds, which could increase the risk of a crash causing injury and/or damage to property. Correction: Vehicles will receive a special extended warranty coverage of 10 years/240,000 km from first registration. Under this special coverage program, vehicles which experience this condition will have the electric power steering module replaced.
On certain Hybrid-powered vehicles, the direct voltage converter (DC-DC), which converts the 158 volts of the Integrated Motor Assist (IMA) battery into the 12 volts required to power the 12-volt battery and electrical components of the vehicle, may have been damaged during testing prior to vehicle assembly. If excessive voltage was applied to the diode chip during testing, the diode chip may be damaged. The performance of a damaged diode chip degrades over time and may cause the DC-DC converter to short circuit and the main fuse for the 12-volt battery to blow. A blown main fuse will prohibit power from being provided to the vehicle's electrical components, which will cause the headlights to turn off, the engine to stall, and prevent the vehicle from being restarted. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the DC-DC converter.
Certain parts of the integrated motor assist (IMA) system are located under a metal cover behind the rear seat-back. Over time the weight of rear seat occupants may cause the metal cover to come into contact with a rubber cap covering an electrical terminal. The rubber cap may get pinched, exposing the electrical terminal. The exposed terminal may come into contact with the metal cover, which could result in an electrical short that may blow the IMA fuse. A blown fuse will cause the engine to stall, increasing the risk of a crash. Correction: Dealers will install a plastic cover over the rubber cap covering the electrical cable.
