Leveling jacks and slides issue

[HappilyLost]

Within the last 4-5 trips in our 2020 Cedar Creek 37MBH we have noticed some funky stuff with our leveling system. The front jacks would come down while driving, or when putting them down they would go back up sinking to the ground, when going to level sometimes the back four would only go halfway to the ground, and now twice in the last trip when putting the slides in (4 of them) the front jacks go down as much as they can (front of camper goes as high as it can) and when I’m holding say the slide button and they’re all in I don’t get that pressure whine like I once did. Let me know if anyone has experienced this before and if its self fixable within reason (I’m fairly handy) or if this is a service item (I have a five year warranty)

Thanks!

Get pre-authorization for your extended warranty work through an independent service only shop/mobile and/or call the Lippert tech support line. They have sent me free parts in the past and walked me through diagnosis.
At a minimum, sounds like leaking control valves/bad solenoids.
