Grinding noise when braking? please help
Hi guys so I just bought my new nx 200t a month ago. Everything started off fine. I liked the car except for one thing: braking noise. Last week I visited my friend and parked my car on a sloped road. I think I didnt hit the brake hard enough when shifting from P to R, and there was a collision sound. Ever since then, I have been hearing grinding noise(not always) whenever I hit brake at low speed. It only happens when I hit it pretty hard tho. I took it to the dealership and got it back today the manager told me this happened on all NX 200t models and they filed a complaint and will work on new pads. I knew it was a lie upfront. But since they told me its good to go, I just drove home. Do you guys think I should take it to independent mechanics to check it out? Will it go away with time?
