One problem related to engine belts and pulleys has been reported for the 2008 Jeep Wrangler. The most recently reported issues are listed below.
Driving on the interstate the all of the dash warning lights came on and blinked(abs,esc,traction control,brake,seatbelt) then the vehicle stalled causing loss of control. Luckily no vehicles around and I regained control after going in the median. Put in 4 wheel drive and got out. The vehicle then stalled again turning everything off including 4 way flashers when I stopped at a light. It was dark and the Jeep is dark green. I had a flashlight to warn other drivers. Very dangerous situation. I opened the hood and pounded my fist on the main fuse box. After 3 minutes the vehicle came to life and I started it to get off roadway.
