The transmission’s light came on saying that it was heated. I parked as soon as possible and that’s when the flames were coming out of the hood. I did burned my hands trying to put out the fire with 3 fire extinguishers. I did not want my truck to burn. Now, the dealer is trying to say that they can’t get a conclusion of what started the fire. The truck smells like burned transmission fluid. I sent pictures of the truck to the dealer.
Our vehicle was involved in a total loss fire from the engine compartment while driving. We were driving the unit and noticed smoke, when we were merging to pull of the road flames started coming up and we immediately exited the vehicle and had to run, because it started popping. We were lucky to escape unharmed physically, but the situation could have been much worse. There were no indications or lights warning of engine failure or fire. This occurred on September 2, 2021.
