Is a whine in the AC unit a common problem, but difficult to find and fix?
What is your question?
A high pitched whine or groan is always there when 2018 Escalade accelerates, usually between 10 mph and 40 mph. It is not noticeable at higher speeds or when vehicle is idling. The Dealer Service can not locate the cause or the solution. They claimed to have found a leaf in the cage and claimed to have replaced the fan, but did not provide any written documentation of such. Other Cadilac Dealer service centers deny ever having heard of such a problem. It is annoying enough to get on ones' nerves.
What makes this problem better or worse?
It's worse when accelerating from 10 mph to about 40 mph
How long has your 2018 Cadillac Escalade had this problem?
RepairPal Certified shops can diagnose and repair your 2018 Cadillac Escalade. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Testing and repair is all about duplicating the concern. Be ready and able to show the concern to a repair technician or service management of your Cadillac dealership. Just because it's happening for you in your vehicle doesn't mean anyone has "heard of such a problem" -- it could be isolated to your vehicle. If you can show them the noise, I am certain they can get to the bottom of the concern. Be persistent but most of all, show them.
