I've had my Bolt for less than a day and driven about 10 miles so far. I tried using Lane Keep Assist on the drive home and was told that the system was unavailable. It's enabled in the Vehicle Settings screen. I'm pretty sure I was going faster than 37 MPH, which is the lower threshold of the system. I haven't checked the windshield yet to see if there is something blocking the sensor. Am I missing something here? And is there a way to make sure it's enabled all the time? I've checked the manual and it's not clear if it's enabled all the time.

Should've been a button on the steering wheel to activate. Then on steering wheel console there will be a car with two lane markers on either side when the camera can see lane markers.

I hit the button on the steering wheel and that's when I got the message.

Dealer checked things out, they can't find a fault that would cause the system to not work. They're gonna have to refer the issue to the engineers in Michigan.

Hope they find the issue. Also speaking of a problem like this, I hope they have done the same things as the Volt. With tthe Volt the dealer calls GM and a team at GM tells us gen what to do/replace. That way all the problems across the country are handled by a small team rather then 800 different mechanics conning up with their own guess. Also it relieves the dealer from responsibility of replace wrong item.

Does this work for anyone? I see it light up on the screen, but there is no "tug" on the steering wheel or an audible sound.

Seems to be worthless (or possibly broken).

Mine behaves the same. I was hoping to get a tug/vibration on the steering wheel and/or audible tone, but that doesn't seem to be the case.

In rereading the manual, I'm wondering if we have discovered a defect. There should be a warning sound.

The key phrase may be "The system will not assist or alert if it detects that you are actively steering."

Below is from the manual:

Lane Keep Assist (LKA)
If equipped, LKA may help avoid crashes due to unintentional lane departures. It may assist by gently turning the steering wheel if the vehicle approaches a detected lane marking without using a turn signal in that direction. It may also provide a Lane Departure Warning (LDW) alert as the lane marking is crossed. The system will not assist or alert if it detects that you are actively steering.

When on, is green if LKA is available to assist and provide LDW alerts. It may assist by gently turning the steering wheel and display Aas amber if the vehicle approaches a detected lane marking without using a turn signal in that direction. It may also provide an LDW alert by flashingAamber as the lane marking is crossed. Additionally, there may be three beeps on the right or left, depending on the lane departure direction.

Update: car has been back to the dealership to get a more thorough diagnostics at the request of GM engineering. They did some sort of extended software diagnostic download that took all day to do. I have the car back, but LKA is still not working. I suspect that the camera module is defective in some way, but isn't generating a diagnostic trouble code for some reason. Obviously something very subtle is wrong.

Sounds like this was written by a committee of lawyers. It may be there, it may do something etc. How do you tell if it is installed and working except to barrel down the 405 and let go of the steering wheel?;)

I would suggest a gentle curve at about 40 MPH with no traffic. Let go of the steering wheel and let it drift over gently into the next lane and see what happens. Make sure that LKA is actually on when you do this. There's a button on the lower left side of the steering wheel to turn it on and off, and there should be an icon that looks like car on the road in the instrument cluster to indicate it's on.

You don't need a curve. Just drive down the freeway with nobody close to you and hover your hands over the wheel in case you need to grab it. Sooner or later you'll drift to one side or the other.
I have done this. The icon on the dash turns amber, but there is no audible signal, and the car crosses the dividing line between the lanes.

I'm sure they will have a recall and software update soon.

Well, it seems that at least the Lane Departure Warning system is working for you. I don't even get that...

Hmm...Mine works. It will tug my Bolt back towards the center of the lane if so take my hands off and let it drift towards the painted lane. It will even yank me gently towards the middle if I drift towards the lane divider with hands on the steering wheel.
I'll also get audible beeps and warning messages to put my hands back on the wheel.
My Bolt can "drunkenly" navigate an easy turn on the highway with LKA active.
