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?
I’ve had my 6 in GS or Sport trim in the U.S. version since March this year (bought brand new on clearance and got $7K below MSRP at the time w/c was a great deal). I already have the 2.5T engine in my CX9 so decided was fine with the NA 2.5L engine in the 6 as it’s also just a daily driver for me. I had a 2014 Ford Fusion Hybrid for 3.5yrs and that was a reliable car but it was a company car so returned it afterwards.I’m close to purchasing our second Mazda-this time a 6. We already have a 2019 CX5 Signature and it’s been trouble free.
Weird. My 2018 hasn't had a single issue. Feels bulletproof.I've had a lot of issues with my 2018 Mazda6 Signature.
I purchased the car new back in May of 2018.
Specifically, regarding the engine, I've discovered an oil leak around the Oil Control Valve on top of the valve cover (which seems to common on the NA 2.5L as well). Also, engine has been running very rough and is now saying there is a misfire in cylinder 2. My dealership is working with Mazda Canada since December and the car is still not repaired. The issue seems to be complicated as it's still not fixed and it's been to the dealer 3 or 4 times since the initial dealer visit for the CEL in December. I am currently in a rental as the car is idling so low and rough i feel it's at risk of doing damage to itself.
I was intially told they may have to replace the engine. The latest is they are thinking it needs to be decarb'd.
My 6 has also had a bunch of non-engine related issues as well:
- Suspension knock noise from left strut area when turning right with speed and hitting bumps.
Confirmed in others' cars as well (Mazda6club.com). I've confirmed this myself in 3 other Mazda6's.Hi, My first service appointment is a week or so away but I thought I would post a video of the noise to get some feedback. I am noticing this pop/knock in the suspension when hitting bumps and turning to the right. I've tried to catch it in a video, which I've posted on the YouTubes...www.mazda6club.com
- Signature seat back trim issue (breaks easily and is a huge pain the butt to replace)
Hi Everyone, Thought I'd share another issue I found on my car. I had the car for a road trip this weekend and had two people in the rear seats (first time I had rear passengers for such a long trip). I noticed today when I was cleaning it out that BOTH of the trim pieces in the rear seat backs...www.mazda6club.com
- Under belly sound insulation folding when driving through slush on the highway. Most of the panels beneath my car have been removed because of this issue
Howdy, Dealing with another issue with my 6. Seems the underbody insulation doesn't play nice with snow and ice. This has happened a few times. Insulation is bending backwards and dragging on the road. Makes quite the noise and is now directing said snow and ice between the body and insulation...www.mazda6club.com
- Annoying steering wheel squeak noise
Hello! I've got another noise. Just wondering if anyone else's car is doing the same thing. My '18 Signature 6 is making a high pitched squeak noise when turning the steering wheel and the turning indicator is on. It sounds to me like it's the mechanism that triggers the turning indicator...www.mazda6club.com
What year is your car? Turbo or non-turbo?lol i had my engine replaced at 24k, another member had their engine replaced as well at around 100k
It had a dead cylinder. In other words, compression was down considerably in one cylinder. My dealer had a similar situation occur with a cx9 with the same engine. This is the same thing that @FrozenApple found in his CX5 as well. So that’s 3 vehicles that I’m aware of that all suffered from dead cylinders and needed a full engine replacement.What happened to your engine specifically GTEyes?
