My 2016 Trailhawk had its ABS control unit go out at 47k miles. It's disabled a host of other features like 4wd and even remote start (things that shut off if a light is on).
Dealership says $2500 to fix on top of the $400 I've given them just to tell me what's wrong. Chrysler/Jeep says the warranty doesn't cover it.
That's my experience. Needless to say I won't be looking at other Jeeps once I can get something else, I regret trading in my Wrangler for this.
