Going around a turn in the mountains at a slow speed, my traction control kicks in and there is a grinding noise, I loose the use of the breaks completely until the traction control turns off. I took it to the dealer and they told me my springs and shocks were bad. I replaced all 4 of the springs and shocks and the problem persists. This is very dangerous and scary.
