Any IP that you don’t own could land both you (and Epic) in legal trouble. So the General Lee’s likeness and name is owned by whoever owns the Dukes of Hazard. Since the IP isn’t ours and we can’t get a license, that would be a problem. Same with KITT from Nightrider.
Making an indirect reference as long as it’s not a direct copy is usually less of a problem, but it can’t be too close. Maybe the Corporal Jones and KAAT make an appearance instead.
