My soft close feature suddenly stopped working and now it slams shut. What happened and how do I fix it?

I've had a strange issue with my drivers door the last week. I go out and unlock my door with wireless clicker. Then I reach in put the key in the ignition start the truck, make sure the defrost is on. Then I step away and slam the door, 'bump',,, I look back, the door did not click shut, again I slam the door 'bump'..it does not click shut. Bump Bump Bump...I try to shut it...then I reach in and push the lock/unlock button , lock/unlock...lock/unlock...on the door..click..click...it does beep or the horn toots..remember trucks key is in ignition , truck running, and I'm clicking the button on the inside of the door. Finally the door will shut and hold closed , once it was not locked,,,once it was shut and locked. I had to get my other set of keys to unlock the door.

This is usually a defective or loose bottom door switch or that switch's mount is loose, misaligned or broken.
It's usually caused by opening the door while it's cooking instead of hitting "stop" first) or slamming the door or both.
My help file on door switches is here.

Check for long items, too big to fit in the fridge.

You need to replace or clean the 1150464 HINGE KIT http://www.kohlerserviceparts.kohler.com/AccessoriesInformation.aspx?ServicePartID=5563b058e2e042868c7a19398797ecd6

it does this get used to it.

The top lid of my soft close toilet seat slams shut.How do I adjust Jiko Mio close coupled toilet.

Call kohler they do have replacement cylinders

Will it close shut but not stay or just not close at all? If it closes shut but not stay its probably the door catch.

It needs a new air shock on it. You might be able to take the old one apart and fix it but replacement would be best.

You could glue soft rubber blocks you have cut to suit and put in the appropriate places.Sounds like the door rubbers are a little worn.
