My Jeep Wrangler warning light cycled on under normal driving conditions. I drove it to my mechanic he said the code read was for the transmission. We checked the transmission fluid and it was filled with fluid. I drove it home into my driveway and I saw smoke and looked under the vehicle. I didn't find anything. When I stood up and walked around the vehicle I noticed smoke coming from the engine compartment. I lifted the hood and flames where present. I closed the hood and ran for fire extinguishers to put out the fire. The Jeep has always been maintained and only has 92k miles on it. The whole incident was captured on my Ring Camera.
While working my mail route, only about 20 miles in, my right hand drive Wrangler started to smoke. I assumed because the vehicle never turned off when it began to smoke it was something small causing the issue. I was driving 15 MPH when this occurred. I pulled over, shut off my vehicle and opened the hood. There was a fire on the passanger side of my vehicle under and behind my battery, rolling under the vehicle moving very quickly. I immediately closed the hood, got my belonging out of my vehicle and watched as it blew up, and I called 911. My vehicle is totaled. I am now learning that this is becoming a common occurance with Jeep! Why are there no public warnings!! Where are the recalls!!!!!!!! I and others could have been hurt or killed!!!!
The engine was on idle. The car was stationary. I pressed the gas pedal. The car did not move. I saw smoke coming out the air con / fan on the dashboard. I got off the car and look underneath it. I saw red liquid pouring onto the ground and flames. The fire subsequently extended to the entire engine. The fire brigade came and manage to put out the fire. There was no warning of overheating or any lights that would have indicated that something was wrong. The car was regularly maintained (every 10,000 km) at the local Jeep service center. The car only had 77000 miles I have never been off-road. I have never made any upgrade or modification to the car.

I was delivering mail, and while stopped at a box I noticed smoke coming from the passenger side of the hood. I pulled into the nearest driveway, and got out of the vehicle just before the engine compartment went up in flames.
My 2009 Jeep Wrangler 4 door caught fire when my wife was driving my children to school. It had 6,000 miles on it. The Jeep was deemed a total loss by safety insurance. The vehicle had not been touched since leaving the dealership. We contacted the dealer who has been very helpful but forwarded us to the manufacturer . We have been getting the company policies and procedures run around. Customer service to the special investigation unit { no phone number to contact them direct}to the legal department where it is right now. Beware of this problem and the not so friendly customer service that follows. Its been our experience the company is more interested in a law suit than a potential safety problem.
Tl contact owns a 2009 Jeep Wrangler 4x4. The contact stated that there was no heat shield underneath the exhaust system. While driving at an unknown speed, he detected smoke coming from the exhaust pipe. He pulled the vehicle over and noticed flames. There was minor damage to the hoses and wires.

Approximately 4 years ago, the heater core in my Jeep failed suddenly, pouring antifreeze out onto my passenger floorboard repeatedly. At the time I was not aware that it was my heater core. We asked a mechanic to let us know what was wrong and that's when we found out. I am so glad that we noticed it in time because we have 3 dogs that frequently are in my vehicle and one, some, or all of them could have died. This was not a cheap fix as they had to take apart the dash to gain access. I love my Jeep, but come on you guys.... No customer should have to fork over so much money for manufacturer defects.
