Will regular epoxy hold?

Epoxy doesn't like high temperatures neither.
I would rather use high-end thinset, used for marble.

JB Weld has a high temp 500 degree. Many listed on the web up to 2300 degrees.

Can you install a heat shield near the accelerator pedal?

Use cruise control.

Will JB Weld work as an adhesive between steel and the tile? If so, this would work well.

JC Whitney has a high temp spray adhesive that should work.

The glass transition temperature (Tg) which is the temperature at which most epoxies will start to soften is about 325-350. You can always take a few temp readings in the area of concern with an IR gun if you have any question as to what the actual temperature is, I doubt it is that high. The PO probably used a contact adhesive which will soften in any heat. I found that by putting an extra layer in insulation under the dog house greatly reduced the heat at well as noise. I used to get "hot foot" now I can drive barefoot with no problem.

Here is a thought, unless it's a big area and would look obtrusive, why not cut out a large, thick piece of black rubber, like horse mat and install it. It would give you a better surface under your foot.

If the floor under the accelerator is hot enough for the epoxy to break down, you'd know it from driving having very uncomfortable feet (at the least)!

What sort of "tile" is this? Is it vinyl or ceramic? If it's vinyl, I don't know whether or not epoxy would stick--though I suspect it would--but I do know that thin set or other cement-based mortar would not be a good choice.

If you do use epoxy and there are voids between the tile and the floor substrate, add some thickener to the epoxy like microbaloons or silica or possibly even sawdust. A store like West Marine would have these sorts of materials and possibly someone who could advise you on what would be reasonable to use. Epoxy by itself is rather brittle (and expensive).

If it were me, I don't think I'd care for tile in that area at all, for what it's worth. That's just my preference.

Vinyl tile that is a pretty good thickness. With shoes on it isn't uncomfortably hot.
