There are numerous defects related to the steering, the low speed forward automatic braking doesnt work and the front pedestrian braking doesnt work. the lane keep assist works most of the time but the lane departure warning never works. i brought it to the dealer 3 times and each tim eim told that since there are no computer error codes it has to be working. they even gave me paperwork where gm tells the mechanic what to tell the customers who complain that these features aren't working.
