Scion tC RecallsLoad Carrying Capacity Label Incorrect
The vehicle certification label may indicate the improper load carrying capacity rating for the vehicle. This is because accessories were added to them after the vehicle was built, changing the available load that the vehicle can handle carrying. Vehicle owners will be provided a corrected label and dealers will aid in installing them free of charge to resolve the concern.
Specific parts of the rear suspension may not have been torqued properly when installing the rear coil springs. As a result, the rear suspension arms may detach, increasing risk of a crash. The dealership will replace the bolts, nuts, rear suspension arms and rear suspension member sub-assembly free of charge to resolve the concern.
Vehicles have a tire size/weight rating label to inform owners of the carrying capacity of their vehicle. These models are being recalled because the incorrect vehicle weight rating is shown on the information label. This could result in vehicle and tire overloading, increasing the risk of tire failure. Owners will be provided an updated vehicle weight label to correct this concern.
