2023 Chevrolet Bolt Euv

First off the Forward Collision Alert doesn't work until your about 1 to 2 feet from impact, no matter which of the 3 settings it's put on. We were so close to impact to the rear of a semi when the service tech was testing it that I was very uncomfortable. The lane assist doesn't work until you're left of center or it bounces you back and forth like a drunk drive, plus it doesn't always reconize the yellow or white dotted line. On occasion it will completely go over left of center and put you in the left lane. (It will not maintain the car in the center of the lane.) Today after service the appointment on the these problems, 7 March 2023 both the service Tech and Service manger told me they're just warnings nothing they can do about it. The manufacture sells sheet clearly states Foward Crash Alert. What good is it if your crashing when the alert goes off. It aloso clearly states on the sheet Lane keep assist w/lane departure alert. Again if your already left of center before you're alerted or corrected what good is. The Tech didn't even enter anything about the Anti collision not working but he did joke with the service manager about making me uncomfortable when we were about to collide with the semi.
