If anyone has any ideas, I'd be most appreciative. Car is going to dealer on Thursday, but I was wondering if this sounded familiar to anyone:
Here is a description of my Smart Key Problem (this does not happen every time, maybe 1 in 10 or even 1 in 20 times the car is parked):
The car is stopped and put in “P” with the parking brake set. The engine start/stop button is pushed ONCE to turn off engine. The engine stops, but the yellow immobilizer light illuminates on the dash, and the computer screen between the tachometer and speedometer reads “Shift to P” (the car is already in park, obviously, as it has allowed me to turn off the engine). The radio continues to play, and the clock is illuminated. It is as if the car is in “ACC” mode, but I cannot get it to “OFF”. Pushing the engine start/stop button will cycle it to “ON” (where all the warning lights, ventilation, etc come on), but not to “OFF”. The next push of the button returns it to the state it was in when the car was first turned off (immobilizer light, radio on, shift to “P” message).
Exiting the vehicle when it is in this state causes a beeping sound from the security system and the radio and clock remain illuminated. The doors will NOT LOCK using the button on the SmartKey.
The only way I have been able to get the car out of this mode is to actually re-start the engine (not an acceptable solution) and turn it off again. The most recent occurrence was not even solved by doing this; I started and turned off the engine 2 or 3 times, even cycled the transmission from “P” to “D” and back, and it persisted (still gave the immobilizer/shift to “P” message when turned off. I had to leave my car unlocked on the street for ten minutes, with the radio running, while I dropped my kid off at school (this is what I would consider a serious problem). When I then drove the car from his school to work, it shut off normally.
-The Smart Key is always either in my pocket or in the center console, within a foot of the dash.
-The car has never displayed a Smart Key battery level warning.
