Starting out, its not the stock seat belt tongue that's stuck.
It's a tongue from a dog harness. It worked great in the daughters Micra but first time we took the dog in the Pathy...it locked in and will not release. I can push it in all of the way, The red PRESS button will go down so far and the tongue will start coming up. Then it stops. I sprayed some lubricant in there at the start and that seemed to help somewhat but still a no go.
I'm afraid to take it to the dealer to get them to fix it or have them replace it. Here comes the $$$$$$$$.
