For refernce I'm in Memphis Tn, Took my 2023 Yukon 3.0 in for a engine Diagnostic, TSB updates and check engine light scan. Planned / Schedule the service and upon check in was told they will keep the truck for 1 week before they can even look at it and then 3 weeks after for any repairs. That's almost 1 month without a vehicle and no loaner offered. Is this normal what timelines are you experiencing?
