“ABV came on. SCR alerted I needed service. On a 25 mph road I no longer could brake randomly”

“Car aggressively shakes and steering wheel shakes / jerks itself side to side when accelerating. Getting worse with time. GMC has it as a known issue but has been for months. Problem is getting worse the more it is driven. GMC says it is âsafeâ.”

“Two issues here. First is that the car will give a danger warning when nothing is there. Sometimes goes as far as slamming on my breaks. Both in drive and reverse. Second is the lane keep assist. Itâs like it is working backwards. I turned this all off because it would jerk me out of the lane and into the other lane or off to the sides of the road.”

“The car has always had an issue where it would just get stuck in a low gear and RPMs would go high. Does this every single day. But recently it also started acting like it was put into neutral for a few seconds and then back into drive.”
