My G37 is telling me it’s not in park when I shut it off
Hey, as you could guess by the title my G37 is giving me a “Shift to Park” warning when I turn off my car even though I’m in park. I have a 2013 Infiniti G37 Journey Sedan. I’m aware of a water leak located somewhere in the front of my car. I’ve tried sealing it but I have no idea where it’s coming from. Yesterday night it rained unexpectedly and my car got soaked. When I got in this morning nothing was wrong other than the seat wouldn’t automatically adjust and my windows wouldn’t automatically roll down. This has happened before and was gone in a day so I wasn’t worried about it. That was until I went to get out at work. I put my car in park and shut it off like you would normally do but it told me I wasn’t in park. I turned the car back on and tried again but same thing occurred. I’ve tried disconnecting the battery and reconnecting it, I’ve tried touching the ground and positive together, with no result. I’ve even went through and checked ever fuse for a blown fuse with still no solution. If anyone has any information on what I could do or what the problem could be I would greatly appreciate it. I’m assuming it has something to do with the water but I’ve also looked into shifter assemblies. Any advice?

There is a small control module/switch unit attached to the shifter that controls the interlock functions:
When you press the button on the shift knØb to change gears, the white plastic SWITCH ACTUATOR slides DOWN. When you release the button the actuator slides UP. When you put the car in PARK, if the actuator does not go all the way up, or if the switch contacts are not working, you will get the SHIFT TO PARK message.
When this happens you should repeatedly work the button on the shift knØb several times fast to see if the actuator/switch is sticking. A small, quick shot of WD40 to free up the works might be all you need. However, being you have a pre-existing water issue around the BCM area, you will also have to check there as well.
This happened to me once after I installed a aftermarket shift knØb too low on the stalk which prevented the actuator from going full travel.

In NEUTRAL, press down on the white cap. Does it move fully and freely? If so, then your issue might be with the interlock module (see pic above). Some folks have removed that module, cleaned the contacts, and have been good to go.
Did you spray WD40 on the actuator (see pic above)?

I use a aftermarket shift knøb and adapter that needed to be adjusted. My fix does not apply here.
It can be one of three things the way I see it:
1) Either the white pin (that the knøb sits on) is dirty/ sticking/ needs grease (wouldn't hurt to make sure the internals of your knøb is clean as well) ;
2) the shift interlock actuator is dirty/ sticking/ needs grease; or
3) the switch contacts in the interlock module (yellow circle) need to be cleaned.
In rare cases the connecting rod that goes from the bottom of the shifter to the transmission gets out of adjustment (usually due to a worn rubber bushing). For that you will have to get under the car and make sure everything is tight.

There is no reason you have to remove that entire trim panel each and every time. Just remove your shift knøb and pull up on the white pin:
