PS4 Controller model CUH-ZCT1. Released in November 2013 by Sony Computer Entertainment, this six-axis, 3.7 V lithium ion battery controller is uncomplicated to repair. (NOTE: Teardown guide is NOT for this model)
they may be defective. i would suggest taking a toothbrush soaked in alchohol to the stick modules and try to clean it out as best as you can. if that doesnt help then you are looking at replacing the modules all together.
