So far my choice to go for a Pentastar engine in the Gladiator paid off. Granted, we are only talking about 17,000 miles and a 14 months period. Still, the Silverado 1500 with the 6.2 died one week short of 12 months with 14,000 miles on the odometer. My only concern with the Pentastar is the high temperature it creates under the hood on a warm day. That's why I open the hood for a while when I reach home. My concern is about the plastic parts in the engine that might show signs of wear, due to the high temperatures. Service appointments are an opportunity to ask the mechanics to look for those.
