Hill Stop Assist Question

Diverjer · February 29, 2020

I have had this 2014 Silverado Work Truck since May 2019 and put about 8,000 miles on it and until today never seen the HSA display come on or even knew it had such a feature. I looked it up and read about it, but wondered why I never had seen the display before. When I seen it today, it was actually in my driveway which is on a slight incline. The only thing that happened today that is unusual is that I went to one of those car washes where it pulls your truck through while it sprays water, soap ect. and blows dries on way out. Not often this trucks gets washed. Also, I even cleaned the inside good, was thinking I may have hit a switch or something, but according to manual HSA is not an option. Only thing I can think of is that it needed a good cleaning. Not sure of what use HSA is, I spent most my time with a manual transmission and use to hills, but guess it won't hurt as long as it works.

Sorry for stupid post, figured out what is going on. That HSA message doesn't come on unless I remove foot from brake and I guess I never did that until today when in driveway which is a slight incline. Guess it must have always done this and by the time I remove pressure from brake I am watching traffic- not the silly display? Don't see much use for it, why would a person ever stop on incline, leave in gear and remove pressure from brake unless they wanted to move? Guess I am just too old for all this new stuff trying to do the thinking for me?

Even better is if you leave it in that mode for more than a few seconds it unlocks & you roll backwards [emoji849]

Strange, got a steep hill out in a pasture I will try that out.

The feature allows you time to move your foot from the brake to the gas without a little roll back. It is a bit of a head scratcher, at first, for those of us coming from a history of manual transmissions. I can think of situations where this could prove handy but nothing I'd miss!

This is one of the better Silverado features for me.

It's nice when on a steep hill and or towing.
Like it was said already it allows you to go from the brake to the gas smoothly on a hill. I could see this feature being even more useful work a manual trans.
Overall I like it, just wish it was more consistent.

My tr6060 equipped 2010 CTS-V had it. It was pretty nice to get out on the highway from my side road as it's a decent upward incline. To be honest though the no lift shift so when you were ripping gears wide open was cooler... just keep your throttle foot planted. My trucks do the hill start too but it's not necessary... maybe if they offered a manual transmission it would be nice lol

I like it very much glad I have the feature.

Nash and Studebaker had a hill holder way back in the day. I'm old but not quite that old, so I've never seen one, just regurgitating stories from my Dad's generation. Apparently with the clutch fully depressed the brakes were applied to leave the left foot free to engage the clutch and the right foot for the gas, brakes came off with the engagement of the clutch. Any of you that have operated a manual transmission lawn tractor have seen much the same thing with the clutch/brake pedal. Way back in the 60's my HS driver's training teacher said to always right foot brake even with an auto transmission, I pretty much ignored that and have always left-footed braked auto trans and right-footed braked manual transmissions and never had any trouble seamlessly moving between the two. Guess I'm just old, but I see no need for this "hill holder" feature on an auto transmission, just another techo wizardry gizmo to go wrong.

Yup. That rendered this little feature utterly useless to me.

I love this feature on my 2014

I like it. In fact, I wish it would continue to hold until you press the accelerator pedal. But It only holds for a few seconds.

I find it useful on steep hills, especially when trailering. Because, even with an automatic transmission, the truck can and will roll backward on a steep hill.

I'm in my 60's and grew up with standard transmissions. I've owned quite a few trucks, cars and hot rods that were sticks. I kind of miss it a bit. They don't even produce Silverados with a stick anymore...that's ashame.

Back in the 80's I had an F250 with that granny (low) first gear. You could let the clutch out and it would roll along without giving it gas. Wouldn't stall, just roll along. Man that thing was geared to tear down a house. Lock in the manual hubs, put it in 4x4 low, drop it in first (granny) gear and the torque was amazing.

A real stump puller was she?

Reminds me of my '88 F-SuperDuty with the ZF 5-Speed and 5.13 gears. Had never heard of HSA but when I did I immediately thought of a time with that truck when I really really really really could have used it! LOL
