2016 GMC Yukon 5.3l makes a high pitched whine on startup only while the brake pedal is pushed in.
Once you let the brake pedal go the whine will stop. I sometimes whines again if you press it again, this is only when the car is in park, and I haven't heard the same noise when in drive or reverse. Any clue as to what the cause of this can be? No check engine light on at this time.
