Key would not release from ignition, it did not turn all the way to the off position until it had set for several minutes. I could then turn key to off position and key would release. I took to dealer in Poplar Bluff, MO. They replaced the cylinder, pass loc sensor and programmed (this according to the invoice I was given, total $367.46. This was 12/19/11.)
I emailed GM regarding this. At the low mileage I had, I felt they should pick up the tab. They told me to forget it.
Key stuck after noticing anti-theft light coming on. Replaced new cylinder lock with new key, kept old key for trunk & doors to save money. Also needed new dash cluster, it wouldn't take code from new passlock.
same prob with key stuck and now car won't start and they should recall them for lower intakes put 4 lower intakes in on 4 diffent cars all had the 3.1 motors cause of plastic gaskets.cheap use metal upgrade if you do one got 200,000 out of mine
