“About 5 years ago I took my Jeep in because when I hit bumps my radio would go off and on, when I would shake the ignition keys the radio goes on and off. Took it to the shop once they said they fixed it, did it again and I took it a second time, they charge me for new ignition switch and said my keys were to heavy causing wear tear. A few days later it was happening again and I gave up with my dealer in chicago 60660. …”

“I have had the vehicle for 5 months. Appr 4 weeks ago my automatic shifter was stuck in park. After a total of 4 days at the dealership they replaced the entire shifter assembly. 2 weeks later the vehicle died on the side of the road stranding my family 130 miles from home. It was decided by the dealership that there was a blown fuse caused by an electrical short of some kind. After an entire week at the dealership they replaced the main computer and some misc. Wiring (all warranty work). The day after I got the vehicle back it died again, this time stranding my family 90 miles from home. …”

“2003 Jeep Wrangler tj, the contact points for the 3rd brake light are open to the cargo compartment. Had a hockey stick blade (made of fiberglass) touch these contacts and catch the stick and the carpet on fire while driving. Noticed burning smell when sitting at a stop light, thought it was from another vehicle, pulled away from intersection, looked in back and there was a fire inside the right rear corner.”

“According to internal sales brochures and advertisements the 2003 Jeep Wrangler rubicon is supposed to be the most capable off road Jeep ever. My Jeep has been nothing but problems, which consists of 2 broken axles, faulty brakes, faulty parking brake, faulty u-joint clips, faulty wheel bearing. After paying the dealer to replace parts that should have been covered under warranty, then realizing that they failed to replace another failed part, called to ask about a workaround until the needed part came in. The advice given was to remove the broken axle shaft and drive without it. …”
