Squirrelly Drive Assist

[woodruff13]

Have a '25 Air Touring, bought in Feb. Seems Drive Assist has gotten more squirrelly recently. Drive on the HWY50 stretch from Folsom up into the Sierra, where it goes from excellent 4 lane divided hwy, to narrow winding hwy.

As the road gets more winding, the Drive Assist gets more jerky It hunts within the lane. Gets way too close to the lines. Once, with a marked left turn lane, it chose the left turn lane (at the speed limit), forcing me to disengage.

Anyone else not happy w/ Drive Assist on curvy roads? Or, does my car need help? Or was it a software upgrade?

Ha..funny timing...I have exact same behavior and so much so that I'm taking the car in for a camera recalibration...mine just simply drifts into the other lane on a curve at slow speeds ..it's kinda funny seeing it trying to crash my car ..once on a empty freeway..I just let it do its thing and cross into the other lane to see if it realizes it's in the wrong lane..nope..it owned both lanes with no regrets or feeling sorry. I had to disengage it and recover eventually but yeah, Drive Assist is a 3 month baby learning to toddle in my opinion ..long way to go ..

I have come to the conclusion that Drive Assist on 2 lane highways is at the very least scary and probably even dangerous. In my experience, as long as the lanes stay clean and uninterrupted (like they are mostly on a freeway), then no problem. But once the lines get broken for any reason (an entry or exit lane, a passing lane, etc.) the system frequently gets confused and often jerks the steering wheel to 'correct' itself. Unfortunately, it is unpredictable what sets it off.

More than a few times my passengers have yelped and asked me what the heck that was about. Now, when I see I am coming up to some kind of variation in the road, I grip the wheel hard so a sudden jerk doesn't scare my passengers (or the people driving around me).

I am not sure it's gotten worse recently (I don't use it a whole lot anymore). To me, it has always been bad. I had more confidence in the lane centering of the 2017 Acura MDX I had a while ago, and I use auto-drive all the time on my 2024 X7 even on rural, non-interstate roads. These days on Lucid (2025 Touring) I use it only when I am on the middle lane on an interstate.

Hopefully this is just one of the other software things that Lucid is doing a terrible job at, and I hope it gets better.

fwiw: I would never use the highway assist on anything but an interstate like roadway, and in the lucid I gave up on using it because of the ping ponging within the lane and it sometimes will dive for an exit. I only use the cruise control.

After the 2.6.11 update it also stops working abruptly without a warning, can happen several times during the ride...

Has happened to me A LOT lately. 4 lane highway open road freeway speed immediate brakes and disengage without any warning or sense of reason. Dangerous

Me too. Very disturbing to passengers. But it keeps me awake!

hahaha that always a plus! Better to happen at night than mid day LA traffic
