Sport Only
Check the iN VIN status for eligibility.
BACKGROUND
Due to an improper heat treatment during the manufacturing process, the driven pulley in the CVT was not properly
hardened. Over time, this may lead to abnormal wear to the driven pulley or damage to the CVT belt which may cause
the vehicle to experience a slip accompanied by an abnormal noise and multiple warning lights. Some vehicles may not
move forward after coming to a stop.
CUSTOMER NOTIFICATION
Owners of affected vehicles will be sent a notification of this campaign.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.
Some vehicles affected by this campaign may be in your new or used vehicle inventory. Repair these vehicles before
they are sold.
CORRECTIVE ACTION
Replace the transmission if VIN is affected/included.
CUSTOMER INFORMATION:The information in this bulletin is intended for use only by skilled technicians who have the proper tools, equipment, and
training to correctly and safely maintain your vehicle. These procedures should not be attempted by “do-it-yourselfers,” and you should not assume
this bulletin applies to your vehicle, or that your vehicle has the condition described. To determine whether this information applies, contact an
