I've had them for all of last winter and 2 months of snow this year and the only problem I have had is when it's SLUSHY/FREEZING out. Frozen slush/ice gathers on the bottom of the running board weighing it down so the motor doesn't have enough power to retract them up. Just kick off the slush/ice from the underside and it's fine.
Never had a motor problem(touch wood)
I love them.
BTW Black 05 is selling some on this site!
