New CX-5 GS vibration issue

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?
 
I once caught somebody out who was desperate to make a point but being a mod, my browser displayed IP addresses.
 
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.

"Harmonic vibration", as in an unbalanced rotating part?
 
Harmonic vibration occurs when rotating or reciprocating masses are out of phase. They are addressed in design and wouldnt change with temperature unless there is a lump of ice on something. It would not apply after a 25 minute drive as reported above but at minus 25 materials and fluids might do some unusual things. I dont know about these things in detail but I am 100% certain that Mazdas cold testing engineers do.

Thanks. I just wanted to ensure Puyapim and I had the same understanding as to what a harmonic imbalance is given his statement. It's been a few years since I took advanced dynamics in university so granted I'm a bit rusty, but like yourself I don't see how harmonic imbalance or vibration could be induced by cold temperatures.

I don’t see why not. If the fluid in the mount thickens just enough to create a small vibration that is accentuated by the stamped chassis or other components then that could be one example. I might be using the wrong term here. I’m not a engineer. Resonance might be another term that applies.

My experience with harmonic vibrations was on a ship. After much investigation it was narrowed down to a defined and narrow rpm range on the diesel mains. The solution was to not run the engines at that specific rpm. The vibration could be felt across the entire ship.
 
Hey guys, got word on Friday that Mazda is aware of the vibration issue in cold weather and are currently doing testing and coming up with a fix. They're hoping to have a fix before next winter, it's too late to do anything for this winter.

I'll see if I can get more info to pass along.

My dealer said the same thing to me too. I hope they get it resolve by next winter or they will have a lot of cx-5 back. This is a deal breaker in cold locations.

My background is in engineering so I know where your coming from.

Over the years, car manufacturers have used different materials to soften vibration to the cabin and within the cabin.
From my experience working on cars since the 90s to now, outside the cabin, outside the car,the dominate material used is a rubber base or something very similar. You would have these at most spots where one piece needs to move freely from another, but still be attached.

Examples,
engine -> body,
transmission -> body,
exhaust -> body,
suspension/differentials -> body,
suspension arms -> body, plus many others.

In cold temperatures it's naturally stiffer and would transmit more vibration to the cabin. Rubber base materials naturally break down with heat cycles, exposure to chemicals that break it down, and just age.

My experience with changing rubber bushings.
Older cars that we used to convert to dedicated race cars would have aged rubber bushings that created problems(another topic). We'd replace all of them with solid bushings or a much stiffer, less flexible, material than OEM. Usually we used Polyurethane so there's "some" vibration dampening and memory.
We got a better feel of the road (desired), but much more vibration was transmitted to the cabin from everywhere(less desired).


In the last 5-10yrs, there has been some impressive advancements in creating a quiet cabin and I imagine they've gone beyond the OEM rubber base material to more exotic materials or creative construction.

I had no clue Mazda used liquid filled bushings between the engine and body(which sounds great, but expensive).
If the claim is that it "freezes", then I predict it actually becomes solid (not just thick) under extreme conditions and that WILL transmit a LOT of vibration to the cabin. My guess is that what ever liquid they do use



I'm curious as to what the "band-aid", short-term solution would be and what technology other car manufactures use that are exposed to extreme colds (Alaska, Canada, Sweden, Finland, etc).

100% of the time, materials that work well between extreme hot and cold temperatures, increase in cost astronomically, if it's even possible. Usually it's more cost effective to use different materials for different environments.



I predict they will do a voluntary recall, or bulletin to the techs to replace/add blah-blah for people who have complaints, and then for the 2020 or next generation model, there's a different material for Canadian built cars with a higher price tag. I would be really impressed if a solution was already integrated into the 2019 model year truck.


Perhaps, the supplier who designed, built, and sold the liquid filled bushing to Mazda promised it reduces harmonics by xx% minimum from yy deg F/C to zz deg F/C and internally where they assemble it, Joe Assembler hates his job or is pissed at his manager didn't do his job to what the instructions say, "because it'll will work fine", "those stupid engineers don't know what they are doing", "Reduce my benefits/retirement? Screw you guys".

Therefore it's only a batch of bushings that are out of tolerance and not a poor design.

FYI - For my 2017 CX-5 that was experiencing lots of vibration while the engine was cold (very noticeable at sub -15 degree celsius temperature outside), my local Dealer said Mazda Canada's fix is to to replace the lower transmission mount, which they did under warranty.
 
Ya there is a active tsb on this. Getting mine replaced Tuesday. 2018 gt
Also did anyone that has had this vibration, have you noticed a lack of power at all?
 
It's been super cold here all week and my engine has been completely and utterly dead. Feels like it's running on two cylinders. The ECU pulls timing big time at these temps until it is sure the oil temperature is normal, which takes 20-30 minutes of driving to achieve at temps like this.

My liquid engine mounts froze solid last Wednesday and the car has felt and run like complete and utter garbage ever since. I really understand how frustrated the Canadian market has been over this issue now. This car feels shockingly, embarrassingly crude and under-engineered when this condition rears its head. The little tin can Ford Escort I drove 25 years ago as my first car felt like a Lexus compared to my CX-5 driving experience this past week.

Taking off from stops is the worst of it. The car vibrates so terribly it feels like it's destroying itself. And the NOISE. Like some cheap subwoofer blasting a 70hz sine wave at full volume. Mazda is not getting nearly enough flak for this engineering gaff.
