Wife drives our 2004 2500 so it hasn't happened to me yet. She says that twice in last couple days radio hasn't auto shut down on exiting truck with switch off, now today she said she hit switch to start and hand slipped off key before it started but engine continued to turn over until it started totally freaked her out. I guess starer kicked out once it started at least it still works. I'm not much on coincidences and both these things happened within couple days. So what gives? Ignition switch problem?
