@TheBigHead Some dealers may not actually know there is an issue with the 6 liter. So I’d give him the benefit of the doubt since the 6 liter is old technology. I’m not sure why suddenly some of the 18’s and 19’s began having these issues. Not like anything changed since the 17. I actually have an 18 and have been in several which don’t have these issues. I along with Malibu are a bit baffled with these engines having these issues. With all that being said, Malibu will start doing their own engines and not buying from PCM for the 20’s. If you are going to take a bunch of heat for a problem with engines produced by someone else I would say building them yourself is a much better idea. I hope you get the problem resolved soon to your satisfaction.
