Defect
On certain vehicles equipped with a CVT transmission, the drive pulley shaft could be subjected to high stress during certain operation modes. During the manufacturing of the drive pulley shaft, some parts may have been produced at the lower end of the hardness specification. If shafts with lower hardness are repeatedly subjected to the specific high pressure modes, it could result in the shaft breaking during operation. If the drive pulley shaft were to break, it could result in a loss of propulsion or the front wheels locking up while driving, which would increase the risk of a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will install a CVT software update that contains a stress reduction program.
