Is it common to have to replace t-stats at 94k miles? I have a 2016 and for the past few months truck has been a little cool on the edge monitor. Idling 174-176 and running anywhere from 176-179 normal city driving. When accelerating from stop will increase to 183-188 depending how hard I get on it and then cool back to 176-179 within half a mile or so. Thinking I may have have a partially stuck t-stat. Had stealership look at it a few months ago and their response was “no CEL, most likely partially stuck t-stat but we don’t see an issue”.
