Load 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.

Rear Suspension Not Tightened Properly

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.

Incorrect Vehicle Weight Rating Label

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.

Great car only problem was hit a pot hole at 45mph and tore up my upper and lower controll arms, hub, crossmember, tie rod, and the A-frame... but good car none the less
LOVE my Tc!!! It has been a great reliable car. The Tc may not have all the bells and whistles, but it had everything I wanted for a decent price. We have had ours for 7 years now and would purchase another. The down side over the years were the low profile tires, you hit a pot hole and forget it!
