Multiple incidents and multiple trips to dealership with nothing resolved. Abs activates with vsc lights at low speeds when reversing out of driveway, driving slowly down road, etc. . . No reason I can think of for it to engage. Vehicle makes a loud grinding sound and feels like it won't stop. Very common issue from what I see already reported. Yaw sensor replaced to fix another vsc issue when making left u-turns. . . Almost got in accident when the brakes kept me from completing a u-turn with traffic coming. . . Luckily I continued into driveway without incident. This happened after the above but the above still continue to this day so it was not the cause.
