This type of "thermal event" was not uncommon with the first gen ('07-'11) JK automatics. The trans cooler was in a bad place (bottom of the A/C condenser) and offered inadequate trans fluid cooling. The trans fluid would boil and pour out of the filler tube onto the passenger side exhaust manifold. It would ignite and eventually melt the fuel line, which was under high pressure. Until something shut off the fuel pump it would continue to feed the flames with gasoline. That no one was injured or killed in this was a miracle. Jeep's "fix" was to ercall the '07s - '09s and reprogram the the PCM to flash "HOT OIL" on the dash display. No one knew WTH "HOT OIL" meant so the fires continued.

The operating temp on some of these things was scary hot in high ambient temps. On one that kept flashing the "HOT OIL" warning I saw 235 degrees F in normal driving on a hot day. We put a parts store B&M style trans cooler on the poor thing and it dropped trans temp into the 170 to 180 range. In 2010 or so Jeep snuck out a slick trans cooler as a towing accessory under Mopar Performance. It looks virtually identical to the trans coolers that showed up on the '12 3.6L automatics. I put one on my '09 JKUR and it just simply works. Jeep got away with it on this critical fault. All thos vehicles should gave been recalled and fixed properly.

Dang. All the good responses are taken. OK, I'm going with the visor fell down, knocked the cigarette out of the driver's mouth and set the greasy bag of onion rings on fire that the driver had set on the console. This caused the driver, who was holding his half pint of tequilla (a San Diegan thing, close to Mexico, you see), to drop it in the burning bag of onion rings. He bails, slapping his crotch to put out the flames. The amblance comes, and the rest is history. Fix those visors, people. Safety first.
The improbability of this makes it seem all the more probable.

Can someone actually make some serious comments?
The average human will be completely forgotten within three generations of their death.

Is that serious enough?

Automobile fires contribute to global warming.

The emissions from automobile fires have been investigated. The main gas phase components were analysed in small-scale tests with representative material from an automobile. A more detailed investigation of full-scale simulated automobile fires was also conducted, including the characterisation of gas phase components, particulates and run-off water from extinguishing activities. Three separate full scale fire tests have been characterised: a fire ignited and developed in the engine compartment; a fire ignited inside the coupé, that was extinguished in the early stages; and a similar fire ignited inside the coupé that was allowed to spread until the entire vehicle was involved in the fire. The quantitative analysis of the smoke gases from the full-scale fires showed that emissions with a potentially negative impact on the environment, or chronic toxic effect on humans, were produced in significant quantities. These emissions included HCl, SO2, VOCs (e.g. benzene), PAHs, and PCDDs/PCDFs. Analysis of run-off water indicated that it was severely contaminated, containing elevated levels of both organic compounds and metals. Comparison with data from other vehicle fires found in the literature shows that contamination by lead, copper, zinc, and antimony appears to be significant in water run-off from these types of fires.
