I just bought this vehicle from a used car dealership, since I bought it the check engine light, ABS light, and traction control light were all on. I got the check engine light fixed but ABS and traction control is still on. When I brake it vibrates in the front of the car and makes a rattling sound. I already ruled out suspension and Wheel bearings because it only does it while braking. It's also really bad rattling when I pull into my driveway (unpaved and off-road) I think it's a wheel speed sensor but I also think it could be warped rotors. I'm not hearing any other noise other then the rattling. My car also stalled once when stopping at a stop sign downhill.

Hello, I'm Danny.

The first thing I would do is perform a CAN scan. It will check all the systems on your car and possible codes it may have stored for these issues you are having including the check engine, abs brake and traction control light. Here is a tutorial showing what is involved with a CAN scan:

Once you have this performed get back to us with any code information that was stored in your vehicle's computer and we can then properly diagnose. After that we can also provide you with diagnostic steps. Hope this helps and thanks for using 2CarPros.
