Car Vibration at 90kph and higher

Hey, Black Hyundai Elantra GL 2017 2.0L 59,000km.

I've been having this vibration/shaking issue in my car for a few months, it feels like. The story sort of starts when I got my winter tires at Canadian Tire, and they never balanced them. Bad luck because I had to drive a long distance to work the next day (700km). The shaking was pretty noticeable, but I got them rebalanced once back home, and it more or less solved the issue. The Mr.Lude technician said one of them appears to be a bit warped now. Anyway, I got my All-Season back on a few months later after the car sitting most of the winter. I noticed the minor vibration was there again but with the All-Season tires now. I took it to work, had a slow leak and got it patched, but after the guy rebalanced the tire, the shaking was 2-3x stronger! I said this is ridiculous, took it to an OkTire now. They said my All-Season tires were misshapen, and they wanted to replace the tires because everything else seemed okay. (about 5 years old) I agreed cause I had few options again at the time. After all, my work requires lots of travel. The tires went on, the drive was smoother again, but I can still feel the minor vibration through the car. Feel it in the seat. My cell phone on the dash vibrates.  

The only thing left to try is to take it to Hyundai for full alignment or see if it is a powertrain issue under warranty.

 

Any advice, or anyone else has this issue? Maybe the suspension is just garbage, and it's hard to tell.

When was the last time you had an alignment?

I watched this video too. I don't feel anything in the wheel.


If your steering wheel isn’t shaking, I’d focus entirely on your rear suspension & tyres.

Honestly, I wouldn't be surprised, it all started with C.Tire, Mr. Lude, and OkTire which are all chains that do the min if they can.


Do you have access to a professional independent mechanic, near your area? There may be something bent in the rear which requires an experienced mechanic to diagnose.

Can you swap both the rear tyres to the front & vv to check if the vibration moves/goes away?

If it's an alignment issue it won't stay straight at that speed, if it does then it's prolly somthing else. If you feel the vibration more when you step on the breaks hard at that speed then it's very possible it's the rear rotors, if you feel it in the wheel too then it might be front aswell. Make sure your rims arent bent or misshapped either. 


Car stays straight hands off, nothing happens when I break, or the wheel ... it's just a slight vibration throughout the whole car.

Have you tried to tighten the lug nuts? I know it sounds ridiculous, but that's what happened to me after a break job. Some of the lubricant of the break job migrated to the studs of the wheels, getting the lug nuts loosen, making the whole car vibrates.

I've cleaned all the studs and all the lug nuts, tighten them good in star pattern (my car have five studs per wheel) then the shake was over.
