I have a 2010 buick enclave cxl with under 80000 miles . Sometimes it will stay in park and wont come out for min i just sit and wait. I don't know what the problem is . It does make a little click sound when you press the button in on the gear shifter and thats it every time i press the gear shifter until it lets me put it in drive. Ive searched the web and find some things not much. want to see if I can fix myself before a dealer.
