On certain vehicles originally sold or currently registered in areas of heavy road salt usage during winter months (Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador), the bolts that attach the electric power steering assist motor to the steering gear housing may corrode and break. This could cause a loss of power steering assist. The resulting increase in steering effort could create the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the mounting bolts and apply a corrosion protection coating to the gear housing and bolts. If the bolts bolt cannot be removed, a replacement steering gear will be installed.

On certain 4-door sedans, the coil antenna module located in the driver side rear pillar, which powers the rear defogger system, could generate significant temperatures if the module is subjected to excessive cycling or continuous operation. This could result in a fire developing inside the rear pillar on the driver’s side of the vehicle, which could cause injury and/or damage to property.  Correction: Dealers will update the Electronic Climate Control (ECC) module software to remove the automatic rear defogger “on” function that occurs as a result of manual or remote start of the vehicle. 2013 models also have a “continuous on” feature (enabled at highway speeds in low temperatures) that will also be disabled.  Note: The base functionality of the rear defogger will not be lost.
