Automatic Emergency Braking Applied During Vehicle Break-In Period!

I'm extremely upset right now. We just got a new 2019 Forester and I've been driving extremely careful regarding acceleration and braking. Well, the system doesn't know that I'm the type to continue driving towards a vehicle at full speed when they're turning and it slammed on the brakes!

I'm really worried. The book says to avoid hard braking!

What is the reason for the manual saying to avoid hard braking? What could go wrong because of it?

Thank you all in advance.

Better to brake hard than not at all!

Hard breaking leads to excessive break pad wear. Note your 3/36 warranty covers replacement, probably for just this reason! I wouldn't be too concerned. Enjoy your new ride and give folks a bit more room so the car won't throw a fit.

New brake pads are seated within several gentle stops. After that you are good to go with whatever.

Nothing to worry. Exactly the same thing happened to me. A guy realized that he wants to turn to the store parking lot when he had almost passed the turn. I was not pleased but it prevented a crash. I will take that on anything else.

Unfortunately, the system isn't intelligent...yet...so it reacts to what is in its field of view without anticipating what an object may do.

However, if you weren't driving with adaptive cruise control activated you should have received a sound and visual warning before the brakes were applied and then there should have only been moderate braking for a few seconds before the brakes were applied with full force. If you'd manually braked, accelerated, or swerved during the warning, or moderate braking stage Eyesight would have cancelled the response.

If you haven't already done so I urge you to read the Eyesight manual and watch the DVD (if there is one). The system has limitations and quirks you need to be aware of.

You might also want to reconsider your driving style. Eyesight sometimes highlights problematic driving habits. Most of us have one or two bad habits.

I don't remember a notification before the braking, just one after letting me know that it had braked.

It did give a notification about an hour earlier when getting close to someone (and it didn't brake that time) but went off after turning.

You're correct on that for sure. I'm going to need to learn to drive more safely by Subaru's standards.

@New_Subaru - I think the real problem is driving ahead at full speed assuming that a car ahead will turn...
You should be prepared to stop, even if you don't have to.
What if something happens to prevent the car from turning?
Like a kid runs out in the street and the car has to wait...
Using your brakes doesn't cause any long term damage but an accident will.

You're correct.

I'm going to need to work on giving more distance.

You should be worried, as should those who share the road with you.

If I misread your post that you worded, sorry.

If you are using the cruise control, it's doing what it's designed to trying to maintain a safe following distance. Not all vehicles with turn signals on as they slow can complete the turn for reasons ... like sudden oncoming car, etc.
One day …. your habit (if it is that as I read it) is gonna lead to a world of hurt.





My Bad … I see you have already been chastised.

...and do have a Safe Trip!

I'm relearning a lot as my teens learn to drive. I had totally forgotten that proper distance when stopping, from the car ahead of you, you should be able to see their rear tires contacting the ground. If followed, getting rear ended shouldn't make you rear end the car in front of you.

Thank you all for your responses.

I'll try to work on giving the vehicle ahead more space.

For now, I've been turning off the emergency braking. It kind of scared me.

Hopefully it didn't hurt the Forester. I've been trying to be careful with it.

Dude, don't do it. Work on your driving imperfections. I have a lot of gripes about electronics in Subarus. But EyeSight is one piece of equipment they have nailed it. It is not overly intrusive. You must have been dangerously close to the car in front of you, if the system applied brakes for you.

I've had more than enough of those close calls where you expect someone to turn and they don't for some valid reason or not. I try hard to avoid the situation where a car in front must complete a maneuver in order for me to proceed in my lane; slowing down so that I don't crush the car in front or get crushed by the car behind me. I start thinking about all the time, energy an $ it will take if I am in an accident and I don't want to go there.

Okay, take a deep breath ...you need to chill. What are you going to do when the first scratch or dent shows up?

Nothing ...NADA, Zippo ..is going to happen, the sky is not going to fall and you are not going to warp your rotors from one slightly aggressive stop.

In fact, when you replace brake pads and/or rotors, you need to use some level of aggressive stopping. Below are just three sources all basically saying the same thing. You can look up online the "bedding procedure for pads and rotors" and find a lot of information about this.
