I bought this set for my 2014 last month. Same PN as what you posted. They worked perfectly, and it was the best price I could find.

I put them on a second set of wheels, and the tire shop just installed them like they would any other valve stem. No issue whatsoever. I wouldn't buy tires at the dealer anyway, unless they were running some sort of awesome special deal.Thanks for the links. My TPMS sensors (2013 Volt) appear to be konking out randomly. If I buy these sensors separately, will tire shops take them and use them when I get my tires replaced (my tires are due for a change). I don't think my Chevy Dealer will allow that.
