2020: “Purchased my 2020 CT5 in april 2020. Since then the vehicle has been at the dealership 5 times for the same service driver assist and forward collision system unavailable. Gm has dispatched a senior advisor to test the vehicle and even left a code reader in the vehicle to track its performance. Messages came on again. I recorded it as instructed and the device was sent back to the GM engineers. It has been over a month today 18 september and still no update as to what's wrong with this car. They've replaced and reinstalled cameras and devices and it still didn't fix the issue. …”
