Can I deactivate hill assist in my 2019 Holden Colorado, I think it's playing up; it activated even on flat ground
Answered by CarsGuide
17 Jan 2024I'm curious to know what happened when the hill-start assistance kicked in on the flat. Since this system holds the car on a hill so you can move off easily, it should deactivate as soon as you press the throttle to move. Which means, on a flat surface, you shouldn't be able to feel the system at all. Are you sure this is what's happening. Could the problem instead be a brake caliper that is sticking on, or a hand-brake that is dragging?
In any case, the hill-start system is controlled by sensors that detect that you're parked on a slope and then apply the brakes to stop you rolling back. If any of these sensors is kaput or not sending the correct signal back to the computer, the set-up won't work properly. Conceivably it could engage on the flat but, again, I don't know how you would know.
But the solution is a simple one; take the vehicle to a Holden dealer who will be able to figure out what's wrong and then fix the problem under warranty. Your car is covered by a five-year warranty, so make the most of it.
By the way, disconnecting safety gear is not the best way to go as it can (obviously) make the car less inherently safe and, in some, cases even render the vehicle technically unroadworthy.
