“Driving on the highway traveling about 60. When all of a sudden my truck shut down, thought my foot had got off the peddle but was still on the gas. Put my hazards on and prayed I wasn't going to get smashed by traffic. Then my check engine light came on. And the second engine light came on. As I pull to side of road stop the car put it in park. And tried to start it and all it did was crank and not turn over like I was out of gas. Did research on conditions and it came back default ignition switch. This has just been a nightmare. Only to arrive at chevy. …”
