The Lyriq is just under 6,000 lb. Almost all vehicle lifts at both GM dealer service centers and 3rd party auto service or tire shops are rated for at least 7,000 lb, and if they also service HD pickup trucks, they‘ll have a 10K-rated lift. You’re probably OK for using either your GM dealer or any quality 3rd-party tire shop for your rotations, so long as they have access to the service instructions for updating the vehicle TPMS system to match new tire positions.
all GM dealers servicing any Ultium-based EV will have to acquire at least one GM-specific mobile lift designed for raising/lowering 100 kWh Ultium battery packs weighing up to 1500 lb. If they will also service GMC or Chevy E-trucks w/ the 200 kWh packs, the required fixed vehicle lift will require 10K lb rating. The special movable pack lifts are monsters, rated to lift over 3,000 lb.
