2019 g70 3.3 vibration/shaking at speed 70 or higher

[ajwklajdskla1]

I just bought a used 19 g70 3.3 and there is vibration/shaking at speed of 70 or higher. I know this is well known issue and dealer I purchased this vehicle did alignment before i picked up.
should i replace oem rotor/pads with aftermarket rotor/pads?

Only if the shaking is just when you're braking.
If you've got shaking/vibration when you're going 70 but NOT braking, just cruising on a smooth road, then it's likely you need to have your wheels balanced and your tires checked for proper inflation and any defects.
Since you bought it used, make sure all the tires are the same (brand, model, speed rating). Mixing tires or even just speed ratings can cause some squirrelly behavior at higher speeds.

Thank you for your explanation!
I will get wheel balance from tire shop or sth.

Go to a shop that has ROAD FORCE balancing equipment. They don't all have that.

How is this a well known issue? Heard of the pulsating brakes but not vibration at 70 or above.

I have a 17 g90, my problem turned out the be the brake caliper pistons. I had to push them in and out over and over until they freely moved with little to no effort. Every caliper had at least one piston that was stubborn. Problem solved.

While you have the wheels & tires off the car being road force balanced, have the shop check the runout on the wheels. You might have a slightly out-of-round wheel w/o other obvious physical damage.
