I have a 2015 Escalade (not the ESV). It seems to drive better in auto 4WD. On a very long highway trip of 4,000 miles, I was driving 80 MPH (speed limit of 75 MPH). The front wheels had a strange whirring/whistling sound that was very annoying. I switched to 2WD and the noise went away. I switched back to auto 4WD and the annoying noise returned. So here are my questions:
(1) does it harm the vehicle to keep it in auto 4WD? This is my preference because the vehicle does seem to drive better in this setting.
(2) does anyone else get the strange whirring/whistling noise at high speed when using auto 4WD? does the noise mean that the vehicle is somehow being harmed by the use of auto 4WD?
