What owners wrote

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.
