I bought my Trax in early February and absolute love it, BUT hate the "safety feature" of brake assist. While coasting (foot off the gas), rolling in traffic, and/or braking lightly, the Trax will automatically assist with my braking...causing the RPM's drop in and out of gear and the car seems to jump when I accelerate again. You can feel the car also jerk forward as if I was applying the brakes hard, which I'm not.

Is anyone having this problem? If so, is there a way to disable the brake assist feature?

Thank you!
Danny

Yes! I purchased mine in September and work at a dealership. Just asked my service dept about it and am taking it in tomorrow. Thought I'd google to see if I could find anyone else experiencing and here you are!

Yeah mine "locks up and like stalls /jerks" at the 27mph mark when I accelerate and when I am decelerating it like grabs the brakes or slows down a lot harder after 27 and below if I coast it's like it grips the breaks.

Giving this some more thought, I was wondering if those who seem to have this problem, are using the M instead of D setting on the shifter.

If you are driving in the Manual mode the transmission will shift harder and it will stay in gears longer than designed, it will also downshift hard.

Try using the car in the M if you are not using it see if there is a difference.

I thought brake assist was designed to brake when there was an object sensed in front of the car that the car is approaching too fast. Am I misunderstanding the purpose of this feature?

I don't think that you will find that feature on a Trax, that is found on vehicles that have adaptive cruise control.

Mine is doing the exact same thing when stopped in gear. I was wondering if it's by design to take the load off the engine to stretch the fuel mileage. I've learned to avoid the jerking by not accelerating too fast from a stop.
Edit: I just tested the rollback issue on a very steep road, it did not roll back at all after releasing the brake at a full stop, but there were a few times I was stopped on a slight incline and it did roll back a few inches.

Hill assist is designed to give you a chance to take your foot off the brake then step on the gas and not roll back.

When you are stopped press the brake, if the hill is steep enough the car will not roll back for a few seconds

Its a better feature for manual transmission cars, years ago Studabaker Champion had the same thing on their cars it was more manual operating than the newer electronic stuff of today.

On a 2013 honda accord I had it worked on the down hill as well, I can't see why you would need it with a auto trans.
