The first time I tried ACC was in a loaner Forester while my Tribeca was getting service. ACC was doing its thing following a car in the right lane. I had the ACC set to 75 but the car in front was only traveling about 65ish. My exit came up and I proceeded to enter the exit lane, a short exit lane... You could imagine my surprise when the Forester suddenly accelerated back toward 75 while I was about to enter an off ramp with a 20mph speed limit.

After that, I have my ACC set to Comfort for the Ascent and Legacy.

Surprise may be an understatement! In my area we have several on and off ramps with little to no transition merge space. What you experienced is one of the biggest differences between a conventional cruise control and the ACC. Normally you would have touched the brakes to slow down deactivating your cruise control because of the slower car. ACC does that for you sometimes so gently you don't even notice until EyeSight loses the target vehicle. Now every time I get into heavier traffic I hit the cruise button once to deactivate but not completely turn off ACC until I'm in less congested traffic. ACC is a good system but it does have its limitations. Thanks for sharing.

This is true! And if anyone needs a case for RTFM I think Eyesight and all of it's associated functions is certainly a prime example.

I've had a few scary situations with the lane centering in my 2021 (and in my totalled 2020), to the point that I won't be using it any more.

The most recent instance this past weekend, was essentially the same as the other times. Normal road...no construction, well defined lines, etc. I had my hands on the wheel, but I could feel the lane centering tugging to the right (I was in the the right-most lane). I thought...'why am I fighting this thing? let's see what it wants to do.' So I barely take my hands off the steering wheel and it immediately swerves to the right, which at 65-70mph is pretty scary, and woke all my passengers up. I took control immediately and turned it off, but basically I've lost all trust in the feature.

Good thing it was a forester so it didn't accelerate all that fast!
been there, done that... I've followed people off the interstate onto 35mph side roads with it still set at 75, then I get bored and pass the person doing 30 in front of me and have to slam on the brakes. I swear people think I'm brake checking them but I promise I'm not!

My 21 Touring hugs the center line too close for me. I kind of like it but I'm not comfortable using it.

Regarding Lane Centering - on my 2019 Outback LTD and Ascent Touring I find it annoying. Instead of centering, it seems to bounce me from side to side. In most cases it's off. We have a 2017 Honda CRV with Lane Keep Assist (LKA) that does a much better job.
ACC on the other hand, is super! I use it often, even in heavy traffic it slows, stops and starts just like I'd expect it to.

Neither has Lane Centering, and if you are not providing active steering input, that's exactly what LKA is designed to do. It will pull you back into the lane and stop assisting until you start to head over the opposite line.

Outback got it in 2020.
Ascent got it in 2021.

Lane Keep Assist button looks like this (a car surrounded by two dashed lines that represent lane markings)

Lane Centering button looks like this (a steering wheel surrounded by two curved double arrows)...

Hope that helps explain why lane centering isn't working (you don't have it).

This! Also Comfort mode will give me more time to "correct" any unforeseen adjustments that I encounter. Especially for my Legacy XT.

LOL, it was fast enough when you come to the realization that you only have a few more feet of straight road ahead of you!

I did my first long drive in my new Subaru Ascent of almost 500 miles in the last couple of days. I experienced many of the features like Lane centering and Adaptive cruise control and found them to be awesome. At the same time, I wish to share couple of my experiences with these two features. Curious to hear from fellow Subaru users if they felt the same way + any tips.

Lane centering
When I went through those single lane highways(with barricades on the sides owing to road construction), I felt the car was trying to sharply turn the car to sides, even though lane markings were visible on either side of the road. I was going at 50-60mph and it felt like someone else was also holding the steering and turning randomly against my will. Maybe, the car was doing a its job, but I did not want to disbelieve my instincts. So, I turned off Lane centering in those kind of roads after I experienced this couple of times.


Adaptive Cruise control
If I do 2 quick speed increments of the cruising speed(say at 50mph), the car accelerates to 60mph at a breakneck speed. This aggressive acceleration sometimes scared fello passengers. I experienced the same behavior when I pass a car which had slowed down a fair bit.

You can adjust the cruise acceleration with the I-set buttons. Yours is set wrong. I use the standard mid setting.

Lane keep is wonderful, lane centering is dangerous and utterly useless. It's not a self driving vehicle and never will be. I turned off the lane centering and now I love the lane keep assist by itself.
*Lane centering will pull you to the middle of the lane when passing vehicles on the highway. It won't kindly let you drift to the left edge of your lane when going around a vehicle to the right. It feels like its forcing you towards the vehicle you are passing. It actually is, its pushing you towards the center of the lane. Horrible feeling, not natural AND YES I WAS USING MY BLINKER.

Agree with this, I do not like the feel of lane centering. It's too aggressive and requires too much force to overcome, IMO. In the few time I've used it there were way too many oh shit moments. I do however like lane keep assist, so I did the same and turned the centering off.

I've tried it in an Outback, and loved it. I haven't had the chance to try it in an Ascent yet. I am not surprised though, that they act differently - the Outback steering is definitely a very different feel than the Ascent steering.

Thanks Robert - I did not know they were separate features! I logged 2000 miles this past week and used LKA as its name implies, as an assist tool.
