Turned off LCA

[dato6966]

If one is paying attention to driving and knows how to drive this nanny is more annoying than useful, and may even be dangerous in some circumstances. There I said it.

I'd say it could become dangerous when pulling a trailer unless putting it in trailer towing mode will turn all that "assistance" off

I takes me on offramps I don't want to get off on....

So the most dangerous thing that happened to me using LTA was driving down a one way road lined with trees at 55-60. Long stretch with one very small left turning lane that was there to cut between trees and access other side of this road to go in the other direction.
The Land Cruiser decided to follow that left turn lane at 60mph. Of course I had one hand lightly on wheel and was able to react fast enough, forcing it to stay straight, but if I was not on that wheel things could have gotten interesting.

I would hope Toyota does a software fix to this so we can turn off the steering assist & instead have the option of an audible alarm

If you think Toyota’s is bad, Subarus nearly violently jerks you to the side on exits and turn lanes. Got me in an accident once.

Anyway, I love LTA have never had a problem anticipating its quirks. I find it very predictable when I need to nanny the nanny

These nannies are perhaps somewhat helpful if you want to tune out while on a freeway and using cruise control for miles or on corporate campus under non-complex circumstances and/or where humans are not in charge but they are not and I don't think ever will be helpful or safe in complicated circumstances and where humans are allowed to make choices. There is no doubt a modern car can more efficiently shift than a human, but it can't necessarily shift when I want it to (sometimes I want to short shift, for any number of reasons) or not shift when I don't want it do (sometimes I want to rev it out, for any number of reasons), much less behave like I want it to when I am trying to do something the algorithms don't understand (like accelerate with slower traffic in front to get around that and slower traffic in another lane and cars are accelerating behind me and the driver understands and can reasonably anticipate3 my choice) and can't anticipate or come close to getting right (like when the roads are curvy, there are parked cars, slow moving cars, and various pedestrians who make logical or illogical choices). No effing thanks to a computer trying and failing to think for me. This stuff is dangerous in real world circumstances at least until we succumb to letting the technology control everything and we are passive bystanders (no thanks).

Shutting off the nannies is less intuitive in the LC than my other cars. Bit of a miss IMO on Toyotas part.

If you use your turn signals when changing lanes the system does not intervene.

Not in my experience. And I signal on every turn and lane change. As pointed out, it’s finicky in certain scenarios.

Since I know where the center of the lane is, I turned that interfering robot off.

When I use the turn signal, it also deactivates for me.

Does no one use their signal to change lanes? It leaves you alone if you do. No signal and it tried to keep you in the existing lane.

I use my turn signals and mine still tries to keep me from changing lanes.

There is something wrong with your system. I would take it to the dealer.

Already did, said everything is fine.

 

[LCOceans]

I agree something seems wrong. Are you sure you use the signal prior to crossing the lane ? - I know sometimes that timing can be sort of habitually simultaneous.

 

[TakaraLC]

I never had issues with the system engaging with turn signal on, that definitely is not normal.

Yes I am certain.

 

[LCOceans]

So strange. Maybe try a different dealership if you can. Perhaps they did not know how to handle the issue. I really think something is off with yours. As long as I use the signal there is no pull back in lane at all. Without using signal - a whole different story.

I just farted with it on my way home from the grocery. When you hit your turn signal it electronically defeats the LKAS, and you can watch the tracing lines on the dash indicator disappear. Something is wrong with his LC or…

It doesn't happen every single time so dealer will do nothing about it. Just like my other issues if they can't replicate it easily these vehicles don't seem to store much useful information. That or dealers near me are useless.

My icon never disappears. Are you talking about the one with the lane and the car crossing it? I believe it's specifically "LDA" that's causing the issue for me. It's what blinks and beeps and changes my steering input despite turn signal on.

I can only guess it has no idea where the lane is that I'm changing into is or thinks there's no lane there so tried to steer me back? No clue I've turned it off now after dealer said it's all working as "normal" In there eyes.

That’s not normal at all, definitely worth a trip to another dealer. Mine is set not to correct, but it does beep. When the turn signal is on it won’t even beep at me.

I think Dubdub is talking about the lanes that you see if you have cruise control info screen on the main dash. Green lines on that screen that represent lane centering disappear when turn signal is used.
