The standard warranty on electrical components is 3 yrs/36,000 miles.
The tipm in the kk is the same one that goes in jk and ka nitro which problems have been reported.
Sorry to hear about the electrical problems, i kind of suspect the dealership is being lazy since its only your headlights. The tipm is basically just a fuse box that also houses relays so it could be be just a single loose wire that they don't want to track down.
Also, unless I'm missing something, that should be an install most anyone can do. There are clip on harnesses on the backside, fuses, and two latches that hold it in place. Of course if it didn't fix the problem the dealer would blame your at home install.
