Thanks for that. I’m not aware of any TSBs. I do have a quick and easy recommended fix for the car’s under body sound insulation issue. I think glueing the very front of the panel to the bottom of the car would more than likely keep it from getting weighed down by snow/slush and bending down. Mazda didn’t fasten the front of the panels to the car’s floor but they fasten them very well everywhere else. If I was to get another 6, I would have this done before I left the dealer’s lot. It’s an incredibly poor design. My dealer has seen the same thing happen on a mazda3 and a cx5, so it’s not isolated to the 6.Wow, that’s a bummer. Sorry to hear about all your issues. I’m less inclined to get a 2018 6 signature now. Hopefully they figured out a few of the bugs for 2019.
our 2019 CX5 signature has pretty much been without issues except an occasional crash of the MazdaConnect system. Latest software update seems to have done the trick for that though (second update since we bought the car / Dec 2018.)
The bottom undercladding issue is really concerning to me. I wonder if they changed this poor design for the 2019 models? Do you know if there are TSBs for any of your issues besides the seat trim?
