Hello Kasim, I have found with mine, If I gently shift into park, Key won't go from ACC to LOCK, therefore can't remove key. If I shift to N position first, then pull on the shifter towards me (to the left) while at the same time shift hard into park, Key comes out every-time. Just living with it for now. May upgrade to a 2018. I believe my problem here is in the Shift Interlock solenoid Module. It gets a power signal from the brake light switch, to allow shifter to be put into and out of Park position. When shifter is put into park, the Interlock Module sends power to ignition switch to allow it into the off position and lock steering wheel. Seems there are alot of issues with this interlock solenoid on other vehicle brands also. Google and research Shift Interlock Solenoid, If i get mine fixed will let everyone know what cause was. Have a good Day!! Just to mention once again, if I can get the switch into the OFF position key comes out with no problem, my issue is cannot get switch past the ACC to OFF position without having to slam the shifter into park. I have heard there is an adjustment in the shift module, involving this solenoid, but can't find info to verify this yet.
