1 Service Engine Light On problem

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.
