Turned my Jeep on and the check engine light, sentry key light, fuel light came on and fuel gauge went to 0, Jeep ran for approx 30sec and shut off. Fuses were checked, nothing found out of place. Tried it again, same thing happened. Was towed to dealership to check and fix. Was informed that the main wiring harness near an O2 sensor was "fried" and that wires were fused and melted together. Granted, my Jeep is 9 years old, but this is a design issue, not a wear and tear issue. Why would wiring be placed close enough to a heat source to where it's able to catch fire and fuse together?.
