I just purchased a 2024 Yukon XL Supercruise. I’m having an issue with the suspension self adjusting ride height when I attach my travel trailer. My TT is 28 ft with a hitch weight of approximate 900 lb hitch weight. When I mount my trailer the XL adjusts when it wants to. Sometimes I can’t get the trailer off the jack stand. My 2016 Suburban would adjust almost immediately when it sensed any kind of increased weight on the hitch. One time I got a message on the DIC that said “ride leveling unavailable suspension overloaded”. I took my XL in for 5000 mile service and brought that to the dealers attention and the couldn’t find any fault codes. Yesterday we stored my trailer and when we tried to unhitch the trailer the compressor started working when we were jacking the trailer up off the hitch making it almost making it impossible to unhitch. I believe I have everything correct in the settings. I’m not sure what to do at this point.
