Could not remove key from ignition with gear selector in park. This condition was remedied by pushing the gear selector hard into park for a while. Then total failure came when no amount of pushing the gear selector hard into park would allow the key to be removed. I removed the gear shift cover and reached in and found a micro switch that when tripped allowed me to remove key. I called local dealer and Chevrolet factory toll free line and they did not say this was a known defect. I purchased replacement part # 25864102. I personally installed this and it fixed the problem. There is a steel pin in the gear selector plastic shift rod. The plastic is week and allowed the pin to drift approx 1/2" to left which would not allow the key removal micro switch to be tripped as it should be to allow the key to be removed from the ignition lock cylinder. I called Chevrolet back (tel # 1-866-790-5600) and they set up case # 71-781779261. They told me to take defective part to the dealer and they would contact the dealer to analyze the part for reason of failure. I took the part to the dealer service manager12/4/09. I called Chevrolet several weeks later and they said the dealer threw the part away since Chevrolet did not contact them promptly. I had ask for Chevrolet to refund the cost of the part only (no labor) but Chevrolet says they can't help since the part is now gone. . Read more...
