Full disclosure, a bank wire to my account and yes he did test drive it. It doesn’t bother some people but it drove me nuts paying that much for a truck that has issues from the get-go.

It literally makes driving a nightmare. Also mine does not seem to be effected by oil temp

Well I wish ya the best of luck but my experience with factory trained techs was pretty dismal. I expected them to break out C@lterm and email engineering the file to be fixed or at least have an update addressing the issue. I had to help the guy navigate “features and parameters” in Insite so he could make sure the engine brake wasn’t “latched” and there was a delay before activating it.
