Honda recalls 143K Civics and Fits to reprogram CVT
Honda has detailed a recall campaign that affects approximately 143,000 Fit and Civic vehicles from the 2014-2015 model years.
The company has discovered a problem with the continuously variable transmission software, which was originally programmed to allow high hydraulic pressure in certain operation modes.
The behavior can be problematic for some transmissions due to manufacturing inconsistencies with the drive pulley shaft. Some components were produced at the low end of the hardness specification, potentially causing failure after repeated cycling through high hydraulic pressure.
“If the transmission drive pulley shaft is damaged, it may break, and the vehicle may lose acceleration or the front wheels may lock up while driving, increasing the risk of a crash,” the recall documents warn, though Honda is said to be unaware of any accidents or injuries related to the defect.”
The issue first surfaced in July 2014 via warranty claims related to a broken pulley shaft in the US market. Another report from Canada claimed the front wheels locked following a similar failure.
Service technicians will reflash the CVT software to operate at lower hydraulic pressures, reducing stress on the drive pulley shaft.
