When the two factors are combined over time, the high pressure could cause the shaft to break. If this happens, it would result in losing drive to the front wheels or in them locking up. According to documents submitted to the National Highway Traffic Safety Administration (as a PDF), Honda received the first report of a shaft breaking in July 2014 in the US, and there was a wheel lockup in Canada in January 2015. As of September 3, there were 23 warranty claims about this issue but no reported injuries.
The fix will be an update to the CVT's software, and the recall will begin October 16, according to NHTSA. Honda is urging owners to get their vehicles repaired as soon as they receive the notification.
Oct 1, 2015 - TORRANCE, Calif.
Honda will voluntarily recall approximately 143,000 model-year 2014-2015 Civic and 2015 Fit vehicles in the United States to update the software that manages the continuously variable transmission (CVT), free of charge. Affected vehicles have CVT control software that is written to use high hydraulic pressure during certain CVT operation modes, which as a result may subject the drive pulley shaft to high stress. In addition, during manufacturing of the drive pulley shaft, some parts may have been produced at the low end of the hardness specification. If shafts with lower hardness are repeatedly subjected to the specific high hydraulic pressure modes, it may result in the shaft breaking during operation. 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. No crashes or injuries have been reported related to this issue, which was discovered through the warranty claim process in the United States.
Honda is announcing this recall to encourage each owner of an affected vehicle to take it to an authorized dealer as soon as they receive notification of this recall from Honda. Mailed notification to customers will begin in mid-October, 2015. Additionally, owners of these vehicles can determine if their vehicles require repair now by going to www.recalls.honda.com or by calling (888) 234-2138.
