Constant vibration in 2013 CX-5

Mazda CX 5 FWD
Hi all,
Hoping someone has some advice for me and wondering if anyone else has had similar issues with their CX-5. This is sort of a long story, so bear with me. :)

I purchased a 2013 FWD CX-5 in September of 2012. About three months ago I had brand new tires put on it. A few days after I had these tires put on, I felt a vibration at highway speeds (about 55-60 mph). Seemed like a classic balance issue to me. I took the car back to the place where I got the tires and they re-balanced them. This did not fix the vibration. I took the vehicle back to the tire place again and they did what they called a "high speed balance". Again, this did not fix the vibration issue. I called the tire place back a third time and they offered to completely replace the tires with a different brand (Michelin). Despite the excellent quality of the new tires, doing this did not fix the problem and by this time it was getting worse. The car seems to vibrate slightly/ride roughly at all speeds (but not while idle).

I then decided to take the car to the Mazda dealership where I'd purchased it. They did a thorough investigation, checked the tires completely, checked the axles, wheel bearings, etc. etc. Even checked the grill to see if it was loose and causing a vibration. Finally they told me that the car was slightly out of balance AND alignment and that might be the issue. I told them I'd had the tires balanced twice and they said the machine at the tire place was potentially out of order. I paid a couple hundred dollars for an alignment and got the tires balanced once again. Initially when I drove the car home it felt slightly better, but the next day it was vibrating again as it had before.

A couple weeks later I brought the car back to Mazda for a second time and dropped it off for the day so they could spend the majority of the day looking at it. Again, they performed a thorough investigation of anything and everything related to the tires and wheels and could find no issues. The customer service rep I dealt with was very helpful. He even said he drove not only my vehicle, but another 2013 CX-5 they had on the lot and that my vehicle rode more smoothly than the CX-5 on their lot did (so I'd hate to think how the car on the lot rides).

At this point I'm utterly perplexed. This car does not ride as smoothly as it did a few months ago, and that's putting it mildly. It's pretty unsettling, actually. It's clear to me now that the problem must lie somewhere other than the tires/wheels, but where? I can feel the vibration in the seat, steering wheel, and through the gas pedal. The car also seems to sway or rock slightly at times. I'm at the point where, if I cannot get to the bottom of this issue, I'm going to consider turning the vehicle in and purchasing something else. It's a shame because everything else seems fine, but it's such a pain to drive because of the vibration, etc.

Before trying to diagnose this, I would like to know whether the frequency of the vibration is proportional to the road speed, the engine speed or neither.

I don't see that 'detail' mentioned here. (dunno)

The vibration is pretty consistent. A little bit more noticeable on the highway at higher speeds, but I notice it all the time, any time I'm accelerating or the car is in motion, for the most part.

I didn't ask about consistency, I asked about the frequency.
 
The frequency of the vibration is constant. I feel it slightly at speeds ranging from 5 - 45mph, and it is more pronounced, but always present, at 50 mph and above. I'm not the most technical person when it comes to cars, so I'm not sure I fully understand your question. Hopefully that answers it.

My net diagnosis...
Defective tire or tires. Years ago had a new tire start doing similar while on vacation. Replacement was only way to eliminate extreme vibration at Hwy speeds.
 
Yeah, the odd thing is that I did replace the tires completely and it did not fix the problem. I had one set of four tires put on (can't remember the brand right now) and I noticed the vibration a couple days later. Had those same tires rebalanced, and it did not fix the issue. The tire place then removed the first set of tires and replaced them with a completely different set (different brand - Michelin) which I have now, and still it made no difference :-/

That's odd for a vibration to stay the same frequency regardless of road speed or engine rpm's. We can rule out tires, wheels brakes, and driveline issues because vibrations from these items will always increase in frequency with speed. We can rule out engine issues and vibrations caused by engine driven belts because these vibrations always increase with rpm's.

All that's left is electric motors. The odd thing is you can't feel it below 5 mph. As far as I know, there are no electric motors that shut off below 5 mph but perhaps the vibration is cancelled out by the idling motor. Have you tried changing the speed of the cabin fan to see if the frequency changes? If not, you can eliminate that. I think we can eliminate the radiator fan because that only runs when the engine is quite hot.

I'm thinking it might be the power steering pump since this is electrically driven and could be felt through the steering wheel and perhaps the accelerator pedal and seat. Can passengers notice the vibration?

I wonder if there's any relation to this TSB regarding transaxle bearing: http://oemdtc.com/10920/whining-noise-from-automatic-transaxle-2012-2014-mazda-models

Does noise accompany this vibration?
 
If the first occurrence was noted immediately after a uninstall and install of the wheel, and subsequent rebalances and even tire swap has not resolved it, you might need to scrub your hubs.

When the wheel is removed from the car, this also detaches the bolts that hold the brake disc to the hub. If the rotor gets disturbed from its mounting flange on the hub while removing or installing a wheel, it is possible for dirt or debris to get knocked lose and become trapped between the hub and the brake rotor before the hub-rotor-wheel sandwich is put back together.

I'm with mazdadude, something with the wheel/hub/brake matchup.
Being hub-centric, the rotors and wheels need to be FLAT against each other and the hub, or there may very well be trouble. Best case for this setup also is to torque the lugs to spec. with a torque wrench and not just hammer 'em on with an impact gun.
I know from doing tire rotations and a recent brake job that the hubs on these cars like to crust up, so, that stuff should be brushed away before putting wheels back on.

Back in the day, I had an '01 Escape that I ordered wheels/tires for from TireRack. I put them on and instantly had vibration and wobble. I called TireRack and they suggested a re-balance, which I got done. It did not fix the problem. I found out that the problem was me. I had never owned a hub-centric vehicle, so I was ignorant. Once I knew during install to hold the wheels perfectly flat against the rotors/drums then snug up the lugs to keep the wheels there and then properly use a torque wrench to finish the job, my vibration and wobble were gone. I was amazed that this was what fixed my problem.

Wheel and transaxle issues could create a vibration but the frequency of the vibration would increase/decrease with changes in speed. The original poster stated the frequency does not vary.
 
I had a vibration too. It was my glovebox. I opened it and the vibration went away. Turns out it was offset a little - I tapped it hard (and moved some stuff out of it) and it's fixed. Can't hurt to try...
 
Does the vibration change while turning the vehicle or while braking? The wheel hub and debris in between is very plausable but it would increase in frequency with speed. I initially thought motor mount too. Try giving it some gas (slowly) while holding the brake so the engine is under load but the car isn't moving. If you feel the same vibration than I would suspect a bad motor mount. Try this in reverse too. Does the vibration change at speed if you start coasting? If you have a laser thermometer than shoot it at each rotor to take the temperatures. They should all be within 10% of each other from left to right but not front to back. If one is significantly hotter than the other than I would suspect a frozen caliper, which will heat up the rotor making it warp and causing vibration. You can also just use your hand but be very carful as they can get very hot.
 
Anything on this? I'd check for a crack in the wheel somewhere, particularly in the lugnut area. Tire dealer might have gotten a little carried away with the impact wrench the first time around.

A vibration caused by a damaged wheel would vary in frequency at different road speeds. So I don't see how that could be it.

There is no predicting how a damaged wheel will act. Just a thought.

That hasn't been my experience. Wheel issues always exhibit different symptoms at different speeds. It's the nature of the beast.
