Has anyone noticed that their Yaris seems to pull to the left sometimes when driving?

I'll bet that's the LTA activating. It's the function that keeps the car on the straight and narrow or more likely the slightly curvy. It feels like a tug to the left or the right on the steering wheel. The car most likely beeps a lot, too ?

Almost certainly it’s the LTA. It can be particularly annoying and sometimes frightening if you’re not expecting it. I find it more annoying if I’m driving on narrow roads or streets because it appears to get confused at times. But a lot of people find it useful on wider well delineated roads. If you don’t was to use it then you can cancel it, but it comes on automatically beginning of every new journey.

That's interesting because on my 2020 Launch Edition, if I cancel it on the steering wheel button, it STAYS cancelled until I next activate it with the same button; even between/after restarts. i.e. it remembers my last setting even after a power off.

That's definitely not how it is on the MY21, A long press on the LTA button will turn it off, but only till the next restart.

Yes, and it really annoys the missus as it tries to steer her back into the parked car she's going past.

And I know that if you indicate it won't activate the lta but who does that? 😀

The 'auto-steering'/lane guidance that the cruise control uses (short press toggles) is remembered, but the you're-crossing-a-dividing-line warning (long press toggles) resets to On every time the car turns on.

Lucky you Colin, I think it’s a pain in the posterior 😂

@Cyker has already partially clarified but just to clarify further, I was referring to a short press and not a long one but this part "you're-crossing-a-dividing-line warning (long press toggles) resets to On every time the car turns on" in my car, only flags up warnings and does not force the steering when Cruise Control (w/LTA assist) is switched off.

What I am meaning is that the LTA has two distinct modes of operation when Cruise Control is active. One whereby it will actively steer the car if drifting out of lane and another (CC still on) when it will just issue warning sounds and/or visual indications of drifting out of lane. This behaviour is changed by toggling the steering wheel control.

With respect, I think you are mistaken. The short or long press does toggle Lane Centring with Cruise control on, lane centring is not active if cruise control is off.

OTOH, LTA, unless it is turned off with a long press, will always try to keep the car "on the road" as opposed to "in the ditch". This is noted from page 220 onwards of the OM52N30E owners manual. Firstly there is a warning, default is the beep, but I switched it to steering wheel vibration that I hardly notice, then there will be a definite steering action in one direction or another.

TBH I find the LTA function globally nice to have and, now, I would not turn it off.

[Cyker]

Yeah, so there is the more overt trying to stay-in-the-middle-and-follow-corners mode that only comes on with the CC (short press toggles), and the more subtle gently-pushes-you-away-from-the-lane-edges-and-feels-like-tramlining that also beeps at you if you cross a lane marking (long press toggles)

If you have a long straight road you can make it gently ping-pong between the two lane markings (Don't do it with kerbs as there is a strong possibility it will kerb the wheels - The guidance is very gentle), but frankly it's about as consistent as the speed limit recognition so if you try this be ready to catch it when it suddenly just drives off the road

I think that the only mistake I have made is not explaining myself as well as you have. If you check my second paragraph, that was referring only to the situation when CC is on for both scenarios and I was never referring to a long press at all.

Point taken but, like you, I have changed it also to "steering wheel vibration" but I have never experienced any attempt by the car to pull on the steering wheel during any of these warnings whilst CC was off. I can only suggest that this may be because the car has never "thought" that it needed to take such an action whilst I have been driving it. I do, however, make use of LTA when on motorways when it comes into its own but I sometimes toggle it off (CC still active) when driving on delimited windy country roads as I prefer to be in full control of the steering in those scenarios.

As drivers, are we slowly being trained to accept self driving vehicles ?? 🙄

You could argue that there is some truth in that! 😉

That's understandable, each to his own. I leave LTA active, I get gentle tugs on the roads around here all the time, but oddly enough almost never when I deliberately cross the centre line, when I have clear visibility and no other visible traffic.

I rarely use the CC on the roads around here, I tried the limiter, but have used it so little that I forget to turn it off when I try to overtake, so I haven't fully learnt how to use it.

Yes, automobiles will event evolve into mobility solution. That is how most car manufacturers see the industry evolving into. 

[Spo2]

I don't put off any safety system. There would have been lots of R&D gone into this and they are certainly value added else they will not be there considering cost cutting is so prevalent in the auto industry. In my past car, LTA, collision warning, auto start on off etc everything thing worked perfectly. So far they looks good in C-HR too.

Road camber also has the Impact of steering pulling.

True, but not like the LTA effect.
