2018 TLX Brakes Squealing and Vibrating - What gives?

0

Rachel A. · rep 0 · May 22, 4:56 AM · 1 replies · solved · Question

My 2018 Acura TLX A-Spec, with about 45k miles, has developed a really annoying brake squeal, especially at low speeds. It's not constant, but happens almost every time I come to a stop.

Lately, I've also noticed a slight vibration through the pedal and steering wheel when I brake from highway speeds. It's not severe, but definitely noticeable and wasn't there before.

I had the pads and rotors replaced about 15k miles ago at a local shop, but this issue seems to have cropped up in the last month or so. Could it be warped rotors again, or something else? I'm trying to figure out if this is a DIY fix or if I need to take it back to the shop.
