Thanks for the report. Just did 2k miles in one over two weeks driving from Florida to DC.
Picked it up in PC section as our assigned car was a piece of junk. Overall I was impressed with the Enclave, thought it was going to be a bit too big but found it really roomy inside without having massive external dimensions. Handled well and had enough power on the interstates.
The only weird thing we experienced was going up hills in th mountains a weird noise went off sort of like the seatbelt alarm. Happened on multiple occasions and only on steep climbs. Strange and annoying!
