Mine did this on a Gallardo a few years back and it turned out to be a leaking line, not the pump. Shop quoted me for the whole pump unit until a second garage found the actual leak in about an hour. Get a second opinion before you approve anything.

Check the fuse and relay first, it costs nothing. If the lift is hydraulic, the usual suspects are the pump, the accumulator, or a weeping line at the front axle. A proper scan for fault codes before anyone touches a part would save you a lot of guessing.

Bought a used Escalade myself last year and paid for a proper inspection beforehand, genuinely saved me from a suspension nightmare since they found a leaking strut the seller conveniently forgot to mention. Definitely confirm upfront exactly what’s covered before booking, some places really do just check fluids and call it done.

Brake rotor runout measurement is a nice bonus most basic inspections skip entirely, usually just a visual pad thickness check. If you’re already worried about the 6L80 and mag ride, make sure whatever inspection you book actually road tests it long enough to catch shifting issues under load, not just idling in a lot.

Had a similar inspection done on a Tahoe with the same platform underneath, worth every penny since they caught a rear main seal starting to weep that wasn’t visible without actually getting underneath. Definitely push for something more thorough than a basic pre-purchase check.
