Seats and restraints
2018-09-26 · campaign 2018-535 · 780 vehicles
Certain vehicles may be equipped with rear seat belt retractors that do not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 208 - Occupant Protection in Frontal Impacts. The automatic-locking retractors (ALR) of the rear seat belts may not switch to a locked position when the seat belt is fully pulled out of the retractor. If used to secure a child seat, a seat belt that is not properly locked could increase the risk of injury to the child in the event of a crash. Correction: Dealers will inspect the rear seat belt retractors and replace them if necessary. Note: If the ALR is not working properly, a child seat should not be installed using the vehicle seat belt until this recall is completed.
Powertrain
2018-06-28 · campaign 2018-348 · 683 vehicles
Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 210.2 - Lower Universal Anchorage Systems for Restraint Systems and Booster Seats. A small amount of structural adhesive may have been inadvertently applied to the child seat anchorage bar during the assembly process. If this condition is present, the child seat would not be able to properly engage the lower universal anchorage system, which could increase the risk of injury in the event of a crash. Correction: Dealers will inspect the inboard child seat anchorage bars for adhesive and remove it as necessary. Note: Child seats should be installed using the vehicle's rear seat belts in accordance with the vehicle owner’s manual and child seat manufacturer’s installation instructions until the recall is performed.
