I have a 2015 LTZ Z71 with 41,100 miles and noticed no washer fluid on my way to work. Reservoir is full so I assume pump as well. Can't say I've ever had this issue with any other vehicle. Of course warranty is expired so thanks GM for making sub par trucks!!! I should have kept my '99 Silverado. Seems like that was the last time they made the "most dependable, longest lasting trucks on the road".
