2022 GMC Yukon Denali. Truck sat for a couple days and noticed it started sagging in the front suspension. Took it for a drive and it wouldn’t raise up to normal height in the front. Service leveling system notification came up, took it to dealer and they’re saying it’s the auto leveling system going out. Sometimes it lifts back up and other days it doesn’t. Anyone else had this issue? They’re trying to charge me $3k to change it out. Best part is the module is out of stock with no estimated delivery date. Looking for other routes to fix it before spending that much. Thanks in advance
