I have a 2023 Yukon Denali Ultimate 3.0L Diesel with 12,000 miles and the other day I noticed a whining noise from engine compartment. It sounds like a power steering pump but I believe they use electronic power steering. Possibly a defective idler pully ? The dealer won't be able to check it out for a week. Just curious if I shouldn't drive it until I get it checked out, I need the transportation.

Suggest putting this in the 3.0L section...
I wouldn't drive it if you think it is main belt related (alternator, water pump, etc)...any of those failing while on the road (esp the water pump), could be catastrophic. Your 3.0l does have a turbo, could be that as well...You are correct the power steering is electric.
