2016 Suburban LT with 38K miles. Just lost function of fluid dispensing but wiper still works. Is this a common problem and is there an easy fix I can do myself?

I read the manual and it stated Top Tier gas brands were recommended but no specific octane. Just bought a 2016 LT Suburban with the Luxury package. Previously used just the cheapest regularly (87 octane) gas on my 2008 LTZ.
