I looked through my archives and it was longer ago than I remembered. Back in 2005, twice I caught a Q-PTLKCK (oops, I thought it was TAC).

I thought there were some listed as V, but I entered them as a Q train. I imagine the train continued onto a plant in the southeast - maybe via the NS or KCS.
If the BNSF is still transporting Hyundai parts, maybe they arrive in California and travel the southwest. Or maybe the UP got the service.
