Yes, on the 15 I had to hold the button for 5 seconds and it would usually work but not always.
It is quite aggravating to have it suddenly cut power when you are almost home free.
My 15 had a limited slip, this 19 has an E-locker it may be interesting with the E-locker this winter,
the 19 is tighter in 4wd then the 15 was, the 19 will actually buck and jump a bit in the corners in 4wd.
Yes, that turn onto Waite Road does catch a lot of people in the winter up and down hill.
For a great many years I would make that corner every day, with 4wd and studded tires I never failed to make it up
or stop coming down in the morning, did come close a few times.
My hat is off to you I wouldn't drive a 2wd around here in the winter if I could avoid it, or wait for the road crews to finish.
Unless it was quite heavily loaded.
The Town road that gives me the most issues is the one on the way to the ski area,
so many skiers trying to get to a ski area that are not equipped to drive in snow and they get stuck and end up crosswise
in the road by the time you stop for them and help them get turned the rest of the way around to go back downhill
it can be quite difficult to get started again in the middle of that hill.
My old Dakota was fantastic on snowpack or ice, I had downsized to 245/75r16 tires and it could stop on many of the hills help someone out then backup the hill.
