Before I bought my wheels I did a lot of searching and it seemed like the consensus was that there was no TPMS in the spares on any of the 5th gens. When I was in to the dealer for a TPMS issue a week after purchase they told me the problem was that the spare TPMS sensor wasn't programmed. I kind of assumed they were feeding me a little bs. to be honest at the time.
Finally I got around to setting up Techstream and plugged in to change from winters to summers and found that I do have 5 IDs and pressures reporting. I have a Canadian '15 LE, not sure if it could be a model year change, a Canadianism, or an LE thing or a combo, but thought I would post here in case anyone else is buying a new set of tires and doesn't want to do the electrical tape mod.
