I feel a good amount of vibration under braking at 80 plus down to like 45. Anyone else experience similar? Due to tires?

sounds like rotors not tires!

I got my car CPO with 13k. Could I call the dealer about this?

Mine started at around 5K miles and I will bring it up at my next 15K mile service. This is NOT normal imo. Rotors should not warp that easily and if they do, that means they are getting incredibly hot. Considering I am very gentle light with braking this is weird, especially from this brand. Call your dealer and have them check it out.

Have you gotten tires rotated or changed yet? I've heard (can't confirm though) that overtorqued lug nuts can cause rotor warp.

Definitely sounds like a rotor. All it takes is one really hard stop to warp a rotor. Another possibility is a sticky caliper the is continuously applying the pads to the rotor. That'll heat it up real good.

I have had my car for a month and maybe 1k miles. Haven't had to brake hard once. Noticed almost immediately but blamed it in tires. So does warranty cover this issue?

Definitely rotor. Happened on my old Acura all the time after a hard stop. Dealer charges for rotor replacement, it's wear and tear item.

I haven't had this problem after moving to BMW and hopefully it doesn't happen to my S3 that I just leased...

I guess I will have a hard time proving the car came like that. Either way rotors aren't terribly expensive.
