Lane Keep Assist or Forward Collision Alert Issues Campaign #39570: Service Update

I got my Volt 2017 Premium in November. It took a while to get used to the Lane Assist feature, and the Adaptive Cruise Control.
I have noticed that if the driver uses the lane assist, the correction turn (back into the lane) becomes bigger and bigger, until a manual intervention is required, otherwise you will drive out of the lane or off the road. In engineering terms, the feedback loop is too slow, resulting in an ever increasing correction, or wave that gets out of control. I recommend do not try this unless you are alone in the middle lane without anyone around you. And one may look like a drunk driver, while testing this.
A solution would be to start the correction before the lane limit is crossed, in other-words the correction starts when you are 1-2 feet away from the lane line. This would require much smaller correction and return the car to the center of the lane. The lane assist would try to keep the Volt in the middle, rather than react to crossing lane.
It seems like this is a programming issue, could be solved with a Service Pack update, or new version? What are other drivers experiencing? Any thoughts?

I must have been lucky to have an early programming function in my 2017 Volt from the factory because it was VERY aggressive in keeping me well within my lane. I hadn't driven such an awesome system since I was prototype test-driving Audi's. I loved my Volt. My mother loved driving the Volt over her Lexus. UNTIL GM did a recall in November for some no charge/stall/no start issue or something. All was thought to be well until I discovered that my Lane Departure feature took a dump. Where it was quite aggressive and proficient in reading the lane lines and keeping me in the lane, NOW it will wander frequently fail to notice the lanes (based on instrument panel indication), and then haphazardly wander well over the lane lines before meandering back into my lane. Doesn't seem to care if it's the right side or the left side, day or night, highly reflective painted lines or not, highway or street. SOOOOOO...before I have to take the ever so draining time of suing GM (AGAIN), might anyone have had this problem and already found a solution that they can share? It's already been to the dealer 2 times since the recall for it. They confirmed it crosses the line before reacting. I've got a case open with Chevy and they say that because there are no codes and all the cameras seem to be working, tough sh**. This is obviously not acceptable as I specifically sought a 2017 with this feature and have only had the car for a year and a half.

Unfortunately, as a resident of PA, I cannot lemon law them because I'm out by time, so I will have no choice but to take it straight to arbitration or court. But hopefully someone out there has a far easier fix because I love the car (aside from the fact that I now doubt it's function will "automatically" avoid any type of accident if it can't sense and react in a timely manner to highly reflective lane lines.

I also opened up an NHTSA complaint. As much as I love my GM, I think this will be the last NEW GM vehicle I ever buy.
