Vehicles Affected: Approximately 143,000 model-year 2014-15 Honda Civic cars and model-year 2015 Fit hatchbacks
The Problem: The continuously variable automatic transmission software, which is written to use high hydraulic pressure during certain CVT modes, 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 a lower hardness spec 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.
The Fix: Dealers will update the CVT software for free.
What Owners Should Do: Honda will begin notifying owners in mid-October. Owners can call the automaker at 888-234-2138 or the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236, or go to www.safercar.gov for more info.
