Hello,I cannot remove key from ignition cylinder.The key gets stuck.

What is your question?

The key gets stuck in the acc. position. The only way i can remove the key is by shifting from park to drive and back to park a few times. Sometimes the key returns to off and i can remove the key with no problem.The shifter seems to be working OK. The car only has 39900 km. Can this be a shifter (switch) problem or do i need to replace the ignition cylinder. I just purchased the car 1 month ago and the key got stuck 2 or 3 times in the last week but now the key gets stuck almost every time i use the car. Any advice would be greatly appreciated Thank you Bernie
