New CX-5 GS vibration issue

The Mazda Facebook page is quite responsive. Apparently Mazda is logging how many 2017 CX-5s have this issue based on my Messenger conversion with the Mazda rep. So definitely contact them.

Oddly, we've had a few -20C mornings here and the vibration issue hasn't occurred. But we're not having sustained cold temperature, generally getting pretty mild during the day.

Let's call it for what it is; lack of testing. I suspect that when Mazda changed the engine mounts in their push to make the 2017's even quieter, someone nixed having to redo the cold weather testing That has to cost $250,000 at least; flying 3 or 4 engineers up north, paying they're salary, room and board, transporting the car up there.

The manufacturer of the engine mounts likely claimed they're good to -50C, it's just a drop-in replacement, so why bother with cold weather testing?

I agree that it's a serious flaw. Sure, the vehicle is "safe to drive" but what is all this vibration doing to the integrity of the interior of the vehicle? I don't want to be driving around listening to rattles because of this.

Mazda has an indoor facility for cold weather testing up to -40F. I am surprised this problem did not show up during their tests

Maybe it did and they deem it acceptable. I’ve never felt it but I know how critical some owners can be over something and nothing so I would need to judge it first. As part of my college years I did a course on engine design and primary, secondary and harmonic vibration were a big part of it. Why would low temp lead to it unless it was stiffer rubber or incomplete combustion, both of which would improve shortly after start up. I asked the question about whether it goes when the temp gets to normal and never got it. That always makes me suspicious about someone who gets something stuck in his craw and wants to find an excuse to complain or even reject the car - “don’t answer a question that might dilute your argument”. My 17 does give a slight vibration - and it is slight, through the steering wheel but they clamped the rack directly to the frame to improve steering feel so I expect it. So it depends on just how bad this vibration is before I would judge it. We don’t get North American winters here and I accept that but I don’t accept that Mazda overlooked it. They know what to test in those conditions.

Im sorry but there is absolutely no way on this earth that Mazda missed cold weather testing and if you think its down to hotel bill, you are very naive. They cannot launch the car without documented evidence that the test and every aspect including NVH was done.

Well then their testing sucks. Or their engineers turned a blind eye. I wish I had recorded the sound the car was making when we got back from Turks and Caicos at Christmas; we were on the verge of pulling over and calling a tow-truck. I could feel it though the steering wheel and through the seat. Interior panels were resonating at low RPMs; looking in the rear view mirror, everything would go all blurry because the car was vibrating so bad. I'm not just whining about something trivial like the car having a slightly rough idle sitting at a stop light.

Mazda has admitted that they know about the issue and that they're working on a fix to me and several others. I surmise from that that it's not just a few out-of-spec engine mounts, but rather a basic design flaw that the new hydraulic engine mounts freeze up at low temperatures.

My naive mechanical engineer brain therefore comes up with a few possibilities:

a) Mazda did not do cold weather testing of the 2017 CX-5
b) Mazda improperly did the cold weather testing of the 2017 Mazda CX-5
c) Mazda properly did the cold weather testing of the 2017 CX-5, discovered the issue, looked at the cost of fixing it vs. how many people live in places where the temperatures regularly fall below -20C, and decided to not fix it because of the corporate bottom line.
d) Mazda's supply chain sucks and provides them with inferior, sub-spec parts in quantities sufficient for the for the company to admit there is an issue.

If it still did it when you got back from a journey where the engine has been running for any length of time at normal temperature, I doubt it’s the mounts as they get very hot. I’m not trying to undermine or trivialise your report, I’m just trying to apply some logic. I don’t know if your dealer is speculating or genuinely feeding back from Mazda but there is a big opportunity for Chinese whispers.

The vehicle did this for the entire 45 minute drive home from the airport. There was a cold snap here at the time and temperatures were hovering around -25C during the day. The following day temperatures were still in the -25C range and the car exhibited the same vibration issues. By Monday the temperature rose to a balmy -14C and all symptoms went away and haven't returned, nor has the -25C temperatures.

As far as I know there were few changes between the 2016 and 2017 CX-5s. One of the changes was to introduce hydraulic engine mounts. The 2016 CX-5s do not have this issue. Frozen engine mounts would produce the type of vibrations some of us 2017 owners are experiencing in sub -20C temperatures. I'm not a mechanic so maybe it's not the engine mounts, but just looking at what changed between 2016/2017 and what could cause these temperature related vibration issues seems to narrow the field quite a bit.

Below is my verbatim conversation with a Mazda rep (I redacted my name) via their Facebook page. You'll note that they did not disabuse me of my belief that the engine mounts were the problem.

"Hello,

We recently purchased a 2017 Mazda CX-5 GT late last year. As you may be aware, we recently had a cold snap here in Ontario. Our new CX-5 suddenly became almost unbearable to drive in the -20C~-25C temperatures we had. Very rough idle, excessive engine noise in the cabin, and vibration strong enough between 1500 RPM to 2000 RPM to make the rear view mirrors go blurry with shaking and cause interior trim pieces to start resonating. Once the temperatures warmed up this week the vehicle returned to normal.

After getting in touch with several other 2017 CX-5 owners here in Canada via a forum, we are all experiencing the same issue when temperatures drop below -20C. It is my understanding that for the 2017 CX-5s Mazda changed the engine mounts to hydraulic mounts and that these go hard in colder temperatures, leading to the dramatic increase in noise and vibration.

Is Mazda aware of this issue? If so, what is the planned resolution to this issue and when can we expect it to me implemented?

Hi XXXX. We are aware of the situation and are working on a solution. We apologize for any inconvenience you have experienced, but be sure that this is not a safety issue and that the vehicle is safe to drive. Have you already visited a dealer?
JAN 12TH, 1:10PM
Hi,

I was going to make an appointment but it warmed up on Monday and the issue went away. After discussing it with other 2017 CX-5 owners on a Mazda forum I learned what the issue is and that there is nothing the dealer can do until Mazda comes out with a fix.
JAN 12TH, 3:47PM

We are currently collecting a log of issues experienced by consumers while we try to find a fix. We also want to confirm that the problem is caused by this issue and not something specific to only that vehicle.

I bought a new 2017 cx5 about 3 weeks ago, after the first week while tempreture decreased to under mines 15 same probpem accured to me, I talked wothbthe dealership and Mazda Canada but after lots of arguments they offered me to put me in a rental one but I refused that. When they sell a new car under waranty conditions they have to fix the issue or refund you. I don't think that a sulotion will comes up this winter. This is so dissappointing.

I assume they were going to look into the issue for you, but you refused a rental. What do ya want, jam on it?

Temp dropped the other morning to ambient -16 C, and at that temp, I still had no vibration. I had some high revving when I first started it up, higher than the usual 1500 or so (was sitting around 1750/1800 for a minute or so and then dropped), but I figure that's normal in that kind of temperature to get the oil moving. Still no -20 C mornings yet (thank god), been a particularly mild winter. Yesterday was 12 C at one point, day before was -16. A lot of wild temperature swings, but it's been rare to get below -10 this season. Only -1 here right now.

They already checked it out but couldnt find any solution, it has been couple of months that Mazda is aware of this issue and they still working on it !!! The resone I refused to get a rental car is that if I accept then I can't do a legal action if they couldn't fix it in the near future. Technically waranty means they have to eaither fix it or exchange it if not then refund you.

If you carefully read the whole thread you will see that this issue is likely hard to pin down. So far the mounts are in the spotlight but it could be a number of things or any combination of things.

In my experiences, constructive dialogue always worked better than arguing.

The question is why Mazda still keep selling cx5 in Canada while they have not fixed this issue? When they sold it to me (25 days ago) they already were aware about this issue but nobody let me know this issue would happen to me... This means they have not been honest . They are selling a faulty merchandise. This story is effecting me and other customers not Mazda!

I fully understand your frustration and if I were you I wouldnt be happy about it. Honestly many auto-makers are aware many known issues but theyre still selling it before they come up with a proper remedy. 2015 Honda CR-V switched to a new CVT and suffered a well-known minor vibration issue during idle with the gear in Drive. Honda was still selling it and only came up a fix for MY 2016. I believe the vibration issue only happening under -25C/-13F on 2nd-gen CX-5 is indeed caused by new hydraulic engine mounts. It only happens in extreme condition and it shouldnt harm anything in the short term. Mazda is at fault here by either not testing the engine mounts in extremely cold condition, or by not having a good quality control filtering out inferior parts supplied by engine mount manufacture. Hopefully Mazda will learn the lesson here and replace those problematic engine mounts for you and others very soon.

It was posted previously that Mazda tests their vehicles in their own facility which can replicate temperatures of -35F. I think temperature is just one part of the puzzle otherwise a replacement program would have started already. I’m betting on harmonic vibration which can be difficult to trace.
