Honda YM CITY, YM JAZZ,
What the hazard is
If the drive pulley shaft breaks the vehicle may lose acceleration, or the front wheels may lock up while driving, increasing the risk of a crash.
What to do
A letter will be sent to affected owners. The dealer will install a CVT software update that contains a stress reduction program, free of charge.
Defect
The affected vehicles have CVT programming that uses high hydraulic pressure which may subject the drive pulley shaft to high stress during operation. The higher stresses combined with a shaft of lower hardness may result in the shaft breaking during use.
