Somehow someone convinced GM to go back to a locking steering wheel (my 2001 you can leave the key in the ON position and remove IGN 0 fuse). Maybe GM wants out of the recreational towing business.
In 2015, nearly all their trucks, Tahoe, Suburban, Yukon, Yukon XL, etc have locking steering wheel and the book requires removal of the negative battery cable. So a friend of mine with a 2015 and this problem has purchased a battery disconnect switch. After he installs it we will test to see how much of the programmable memories get lost. Logic tells me everything will go away and another acquaintance in GM service tells me I am correct, but maybe GM was smart enough to specify NON-VOLATILE memory for all the stuff that you have to program when you first get a car.
If not they have stubbed their toe big time over this one. Of course, that makes my stable of older EASILY towed Suburbans and Yukons (one has 400,000 miles on it and still runs great) more valuable. Maybe some smart GM engineer will respond with a simple fix like "remove fuse 22 and Batt11 and you're good to go" but unless there is some easy fix I'm afraid GM is going to lose the MOTORHOME market.
