Today I brought in our 2016 MDX to the dealership to troubleshoot/repair whatever is causing blue smoke to be emitted from the exhaust for a second or two after startup. It does this pretty consistently, usually noticed when shut off for several hours/overnight. This is the second time I've brought it to the dealer, and both times they are unable to reproduce or identify faults that are causing it. The first time the dealer suggested I use only Top Tier fuel (which I have been since day 1), and "recommended" I use Premium fuel. I know premium is not required on '14 and up (we had a '13 prior to this), but I put premium in for a month anyway to comply with their recommendations...no change as I had suspected. Anyone else have this issue? No, there are no notable performance issues or noises, but sorry....I'm not paying ~50K for a luxury SUV that puffs blue smoke. This is our 14th, yes 14th, Honda/Acura since 1994...none have ever blown smoke including my 2006 Civic that had 295K miles on it... a bit concerned my Honda/Acura quality streak has come to an end... I have taken several videos of it smoking.....below is a photo from one of those videos since it doesn't appear I can upload a .mov file..
