One problem related to engine belts and pulleys has been reported for the 2010 Jeep Wrangler. The most recently reported issues are listed below.
I was driving down my residential street and my Jeep's windshield wipers started going off, my horn starting honking and my seat belt light came on. I continued to drive and 3 seconds later it did the same thing but this time it died and smoke started coming through my vents inside. I immediately put it in park and got out to get my son out of the back seat but my door shut behind me and all of the rest were locked. I immediately called 911 because I was watching the car fill with smoke with my 10 month old trapped inside. I was not able to unlock any of the doors until I got to the back hatch, where my key opened it up. I got my son out and about 60 seconds later, it started smoking worse and it turned to black smoke. About 30 seconds after that my car caught on fire. It all seemed to start under the hood on the passenger side of the car.
