1 Service Engine Light On problem of the 2020 Jeep Wrangler

Failure Date: 10/14/2020

Had it for less than 2 weeks (was brand new, purchased with only 43 miles) and decided to take it on a fall road trip. Halfway through our road trip (about 100 miles in) engine started �jumping� and �heaving� while in cruise control on the highway at 65 mp; then woudn't accelerate at all, and speed started to decline. Was very near an exit, so was able to coast in to a gas station. Electronic throttle control error code + service engine lights were lit. Attempted to turn off an on several times, hoping this was just some kind of glitch, but after multiple attempts it woudn't even stay started. While in park, after pressing "start" engine just kept jumping then automatically would shut itself off. Our whole family stranded hours away from home. Under 500 miles and it had to be towed in to the nearest dealership where it's been sitting for almost a week now and they still have absolutely no idea how to fix it. Was told that it lit up with so many error codes they have to get a special engineer from mopar to come out� just in shock that we're having this issue with a $65k vehicle. Very unsafe.

2 Service Engine Light On problem of the 2013 Jeep Wrangler

Failure Date: 07/11/2016

The contact owned a 2013 Jeep Wrangler. The contact stated that the vent controls failed to work for the heat and air conditioner intermittently. In addition, there may have been toxic fumes emitting through the vents when the heat or air conditioner were activated, which affected a child passenger's breathing. The vehicle was taken to the dealer more than three times, but they were unable to replicate and diagnose the failure. In addition, the contact was not experiencing any engine failures before the vehicle was taken to the dealer for a manufacturer recall where the dealer replaced the engine sensors and the transmission. The service engine light illuminated after the repair. The vehicle was taken back to the dealer who provided no solution after the recall repair. The contact noticed that shortly after leaving the dealer, smoke emitted into the vehicle and flames appeared under the hood. The contact was able to exit the vehicle and the fire department extinguished the flames. A report was not filed. The vehicle was destroyed and was towed to the contacts residence. The manufacturer was notified and stated that they would provide an investigation. The contact was still waiting on a response from the manufacturer. The failure mileage was not available.
