NHTSA Complaint #11709298 — 2013 HYUNDAI ELANTRA

I have had a couple of issues that I have had others tell me or read online that they have had the same issues 1- When I bought the car, which was used at the time. Just a couple of years ago I drove it off of the lot and it had a break issue. I had to take it towed back to the dealership bc something broke underneath and the breaks were failing. So they fixed the problem supposedly. I only had a 30 day warranty and after the 30 days the breaks started grinding every time I stopped. This went on for a long time. I had an other mechanic look at it and did something and I can not recall exactly what he said but after about a week, the noise started back up and at that time I had had the car for about a yr and he said I still had about 25 percent left on my break pads. So probably about 4 months ago I changed my front breaks, including the rotors and the back breaks to, I also had to replace the front left caliber bc while trying to take the pin out of the caliber to clean it, the pin broke. So I replaced it. Took my care in to get inspected And they told me I need to do the back breaks and the back right caliber to pass inspection. So I did the work and got it done. I am not a rich person so I can only take it a mechanic if it something that I can not do myself my I have had good training bc had been a mechanic and had taught at mechanic schools so I know I have help and if I am not sure about something he will help. So now after doing all of that hard work, I am starting to hear the grinding noise again with the breaks and my breaks are good. It always starts our really light and then gets louder within a couple of weeks. 2- the second issue is that my airbag light is on, I am not sure why this is , I have never been in any kind of accident. One day just popped on and never went off 3- I have read online that you have had a recalls on newer models for Hyundai Elantra with the issue but not my year. Well my trunk latch ended up get latched and would not open
