Glue gun failure

This post peaked my interest as i was about to do some quick scratch built building repairs using hot glue. I googled the issue and ran into a doll house forum in which many indicate hot glue chemistry (like everything else) has changed and is no longer good for a long term bonding agent beyond a few years as it is more of a quicky craft product.  I wouldve expected Gorilla glue to be better which, by your experience, i guess it was as it got you 6 years.

A change in glue chemistry might explain it because i have some 20 year old structures that were created using hot glue and they are as sturdy now as they were when built , with no glue failures.  I thought maybe I had used a different brand back then but glue formula changes might explain the difference.  I have about 40 cars that will need to be redone with a different glue if this is the case.  What a bummer.

Epoxy

If you don't want it permanent or to damage the car, then your options are limited. Could try Scenic Accents Glue.

I've never experienced this.

Are you using a low temp gun and glue? Maybe the heat from the bulbs softened the glue?

I used a glue gun that I bought at Hobby Lobby about 10 years ago for $20.  I thought it might be the internal temperatures, but this has also happened to populated add on cars that were mainly left on the shelf with little or no run time. 

Thanks @NJCJOE , I may give that glue  a try, as I do not want to cause permanent damage to the seats/interiors.

Try clear silicone.

For just something like people on seats in a car, how about that stuff they stick your credit card to paper with when it comes in the mail? I think hardware, big box, etc. stores also sell a temporary poster hanging tacky goo that is similar to that.

I use Woodland Scenics Hob-e-Tac to hold not only figures but wood, metal and rock objects, it's a pain to remove but I've got 20 year old coal loads being held to the tops of the coal cars that don't show any sign of giving up.
