I've had my 2016 Jeep Patriot for about a year and now had my 1st issue with it. I was making a loud humming noise from the rear on the high way which got louder as I sped up. I took it to a local shop (owner has a Jeep Renegade) and he discovered the left rear wheel bearing was dry, so we replaced it. Now, there's two squiggly lines next to the anti skid light that stays on, the anti skid button on the dash doesn't work. After driving forward about 100ft the 4WD! light comes on and at that point you can't lock in 4WD with the lever under the arm rest... He's putting it back on the lift, said there was a clip that his mechanic insists he replaced.....any advice?
