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 find the lane keeping feature essentially worthless and worse than any other car I have driven... I always leave it off.

LKA is really intended to keep you from accidentally drifting out of your lane during a moment of inattention. (E.g., adjusting the radio, yelling at the kids, messing with the cell phone, etc.) It works fine for that. It is not a poor mans autopilot. So yeah, if you take your hands off the wheel it will ping-pong between the lanes before finally breaking free.

My ELR doesn't have active LKA, but, the alert thing is just as annoying. I leave it off.

Einarulf and Tomt, Wws beat me to it. The Volt system is not an "Autopilot" like the Tesla system. (Not that the Tesla CC is a real autopilot like we may have in 20 years (or less)). I agree that the lane assist, if left to itself, "ping pongs" back and forth between the lines in ever increasing angles. It is not designed to keep you safely in the lane. It is just to "catch" you if you're distracted and would have left the lane otherwise. I personally love it! If you use your turning signals it will not fight you as you change lanes.

The road to my house is quite twisty-turny and I turn it off there. Otherwise it drives me crazy as I make my turns.

It's a great reminder to use your turn signals on the freeway. :D

It works perfectly for me. I don't want a system that allows me not to watch the road, or more importantly, for my kids.

But I did hate it at first. It seemed pointless and irritating. Now it's just a friendly reminder to obey traffic laws.

Campaign #39570: Service Update - Front Camera Freezes
A Service Update Bulletin was released last month for possible issues with the camera features such as Lane Keep Assist LKA) or Forward Collision Alert (FCA) delivering driver warnings when not near the lane lines or without an object in front of them. There is a software update for the forward camera module to address the issue.

This pertains to CERTAIN 2016 and 17 Volts with FCA/LKA

THIS IS NOT A RECALL

Like most service update campaigns GM will not be notifying owners but the service (if necessary) will instead be completed on your next service visit.

SOME dealers may call Volt owners they have worked with in order to perform the updates

If you wish to determine if the update pertains to your car you can call the Customer Support Team OR call your dealer with your VIN

I do the same. Only one of my Volts has it and I keep it off. The FCA I have on all the time. I get very few false positives on it but it definitely is a good thing.

I was in for P2097 and they did this at the same time.

FCA is deactivated after the update is applied. If the cruise control is on,* pressing the FCA button just gives a warning that FCA is deactivated. Turning off cruise control allows you to re-activate FCA and then everything works as normal.

This is probably in the manual, but it provided a couple of minutes of frustration for me and I'm still not sure why FCA activation is connected to the cruise control.






* I don't mean "engaged", but just "on", i.e., the cruise control icon is white.

Something obviously went wrong with the update. They will have to either deal with DTCs that are set inhibiting the system, or to re-do the software in the event of some sort of corruption that took place.
See your dealer!

Perhaps I was not clear, but FCA is working fine now, it was just odd that I had to turn off cruise to accomplish that.

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.
