Hi Paul don't panic I get mine back tomorrow almost for the same thing I lost first gear in drive and also when I shifted down to first I lost that to it started out in second also my key would get stuck in the ignition and I also had the yellow light on in the dash. The fix was they replaced a faulty ignition switch. Good as new they tell me so ask your dealer to look into that it might save them some time. Good luck.
