I have noticed on my last several rides that my 2014 Grizzly with 980 miles and 106 hours goes into 4wd intermittently without me hitting the button. It is always in 2wd drive when I park it (button out). It is in 2wd drive when I start out, no 2wd indicator is on etc. I can tell when it goes to 4wd by the harder steering and the indicator light comes on. The 4wd button is never touched. It only does this when it cold (relatively speaking, it is 75-85 degrees) It does this on pavement for about 900′ before I get to the desert. Once it is used a little bit it works fine and the indicator does not come on again in 2wd. When it does come on in 2wd I stop and push the button several times to get it out of 4wd. It usually comes back on at least once until I drive a little farther. The front diff fluid was changed a 200 miles and is at the correct level. Has anyone ever heard of this problem before?
