2-3 weeks ago I got in my car to go somewhere. From the time I pulled out of my driveway my car was in limp mode. At the same time my check engine light, air bag light, power steering light, service traction light and theft light all came on. I got my car back to the house and when I shut it off it would not start back. I hooked it up to the obd2 scanner and the codes that came back were p1682( faulty ignition switch) and code u0101(transmission control module).
