Hi:
Yes, it could be the TPS, but without a code, you can't be sure. If the dealer can't fix it, (and I do agree it is dangerous), you need to contact the Hyundai rep for your area. Let him know the problem is dangerous and they can't fix it. I'm sure the rep will put pressure on them to determine the problem.
