Hill Start Assist?

Has anyone disabled the hill start assist and noticed that the Jeep gets moving faster from a stop?

The reason I ask is I disabled it on mine a couple of days ago and it does not feel "tight" when I take off. I use to randomly check my e-break when taking off because it felt the break was on for a moment or I was dragging something under the car, but now that I disabled the HSA it feels better taking off from a stop. I don't know if this all in my head, break in, or just me getting use to the way it drives.

I turned mine off one day. And noticed right away that with driving stick, it felt waaayyy better turned off. Like how it should be to drive the jeep. With it on, I would stall out here and there from releasing my foot off the clutch too early or soon, and it would try to kick in the HSA. I thought I was just being sloppy shifting and I need to learn my new jeep. I've been driving stick for 15 years in several cars. I like the feel of driving my vehicles and with the HSA off, I get a better feel of the jeep itself. Like how it's supposed to be.

Hill start holds the brake on to keep from rolling backwards, so you are dragging the brakes as you pull out. It is pressure sensitive. The lighter you hold brake when you press clutch pedal, the lighter Hillstart holds brakes on. It still sucks, much better without it.

You should also be able to find it in your manual, at least my 2009 has it.

No one has popped if with this yet, so allow me:

"Hill Start Assist is genius, I love it, I use it all the time, I never have a problem with it. Unless you're a Sasquatch footed idiot, you should use it and love it too."

Yeah, so, it still sucks. It's nice that they made the effort..sad that the current HSA is the best they could do.

I couldn't be happier that the Premium EVIC allows this to be shutoff with ease, driving without this nanny device is full of enjoyment now. Thank you Jeep!!

Apparently it just adds to the cost of the Jeep and makes Fiat more money?

So you can eat up rear brake pads more often and Chrysler can make more $$$ replacing them for you. I turned it off before I even left the dealer lot, and don't plan on turning it back on.

It is stuff like this that makes no sense to me... I actually started thinking something was wrong with the Jeep before I turned this off. Why would Jeep want this wpexperience for their customers?

Guess I'm the only one that likes it. I turned it off once but I prefer it on. And yes I know how to drive a stick. Been driving one for 20 years.

The only time I notice the HSA is if I'm on a steep incline. At first I didn't like it. Made it tough to find the "sweet spot"'without over revving while on inclines.

I turned it off. I didn't really notice any difference on flat land but starting on inclines was now traditional with the slight roll back.

I ended up turning it back on after it was suggested on these forums that it can be a useful feature to have while off road and is worth the effort to learn to drive with it on.

Maybe I'll turn it off again to see if I notice any difference while on flat starts.

What is the purpose of HSA with automatic transmission? Doesn't the Jeep automatic have the hill hold capability of almost all other automatic transmissions? If not , it sure is a poor substitute.

Am I the only one that holds the car with the clutch? I can take off from a hill without rolling backwards all day every day, without the hill assist. That's the way I was always taught to do it back in the day.

Foot on the brake
Let out clutch till the vehicle damn near stalls.
Let go of brake, vehicle will inch forward.
Push in clutch and let off brake until your foot is totally of the brake and the vehicle isn't moving forward or backward anymore.
Put about 3k on the tach and let the clutch out and give it gas.

I tried to shut off the HSA in the EVIC, but it wouldn't let me. I'm going to try it the other way, but why wouldn't it let me just turn it off??? I could set every other feature with no problem, just not the one I really wanted to change.

I think its only part of the premium EVIC, I don't think all the models have that option.

Yeah, this is only my 2nd auto and the first thing I learned when driving a stick (I was in 6th grade) was how to start off on an incline, it is not that hard.

I used to do this all the time in my Mitsubishi Eclipse but it's actually not good for the clutch.

Obviously only doing it on the occasional hill isn't going to instantly wear it out but combine that with off road (where I try to not use the clutch but sometimes have to) so I'm trying to keep the disc from wearing as much as I can.

I've tried it on and off. I don't NEED it, but it doesn't hurt a thing, and could be a huge help for less experienced drivers. If someone is having issues with HSA they are doing something wrong. It works perfectly and if you are using the clutch right will never know it is there.

I'm quicker than the ABS release, so that statement is false. Unless you expect me to wait before leaving, which I see no reason to do so, its a nanny device for those who never learned to drive a stick properly.

I hate it it's been off since about day 3 of my jeep I don't like the feel of it and the noise it makes when you start going sounds bad I've been driving a stick for enough years that I don't worry about rolling on hills, I will say for someone just stating to learn to drive a stick in heavy traffic it's a smart thing to keep on

I guess I'm old... the above is called "Riding the Clutch" and I was taught NOT to do that as you'll wear out the clutch sooner. Never mind the heat that generated by slipping it. I can get going with only a slight roll backwards on any hill.

I don't mind HSA most of the time. When I usually feel it drag is when I forget and I take off like I would on any other rig without HSA. If I just take my foot of the brake and then give it a little gas slowly, it works fine and you can feel it release. It will hold you for a good 2sec if you let it. Besides, as close as some idiot driver like to park on my rear at a light, it's probably not a bad thing.

Agree. I was taught not to ride the clutch too. I had to park almost bumper to bumper in a tiny, steep driveway a ton. Appreciated not having even a slight roll back before taking off.

HSA on a manual kicks in on a 3% slope, just 1.7 degrees!
On an auto, it kicks in on an 8% slope, 4.6 degrees.

So, manual drivers are experiencing HSA on just tiny slopes, while those of us driving an auto might appreciate it stopping rolling backwards on a steeper incline.

I think bent jeeps comment was taken a little to literal. Those of us who learned to drive on a stick don't have a problem with hills but sheltered drivers like my wife who does not know how to drive one would benefit but then she would come to rely on it and never learn how to do it. HSA is for lazy driving and bad habits. I always referred to riding the clutch as when you are cruising and are resting your foot on the clutch. And the whole point of the clutch is to slip, with in limits.
