2018 TLX Brakes Squealing and Vibrating - What's going on?

0

Melissa G. · rep 0 · May 22, 4:57 AM · 1 replies · solved · Question

Hey everyone, I've got a 2018 Acura TLX A-Spec with about 60k miles on it. Lately, I've noticed a really annoying squealing sound when I brake, especially at lower speeds or when the car is cold. It's not constant, but definitely noticeable.

On top of that, I'm feeling a vibration through the pedal and steering wheel when I apply the brakes, particularly when slowing down from highway speeds. It feels like something is off with the rotors.

I had the pads checked about 10k miles ago and they seemed fine, but this vibration is new. Could it be warped rotors, or something more serious? Any advice on what to check first would be great!
