perhaps start with including the make/model/year truck you have. And have you perused the owners manual to see if there is any info in that about the parking brake?

 

I’d assume you have a 2019 or newer but you know what happens when u assume

 

If nothing else there’s prob a fuse for it u could pull that or just take the negative battery terminal off for a min reconnect 🤷‍♂️

 

I think the same engineering students that designed the electrical system on the Titan sub are designing for GM.
Snowflakes, Millennials, and Ivy Leaguers.
Not car guys.

 

@roorancher I am offended

 

You know exactly who im talking about, and you didnt go to school on the left coast.

 

My truck is a 2023 Chevy Silverado

 

Couldn’t agree with you more about the designers of bees new trucks. I would totally guess these new models were designed by my millennial stepson and his little snowflake friends

 

Since we're doing the guessing game here, I'd guess a lot of the nanny things designed for new vehicles are due to the litigious nature of the US society and not so much about what the millennials think, do or where they went to school.

Just sucks that sometimes the features don't work properly or the owner doesn't know or isn't aware of how to use them.

 

Don't you know me better by now, Tomi? I can turn your argument into Swiss cheese in a NY minute:

"But the parking brake was supposed to set automatically! It's not my fault that the wheels were facing the wrong way on Telegraph Hill, and the car rolled downhill, taking out 10 other cars and a homeless encampment!"

"But officer, my blind spot warning system must have malfunctioned! It's not my fault I slammed into that big rig, causing it to flip and spill cheetos all over the interstate!"

 

So please clarify for me: I have a ‘23 Sierra Denali. My parking brake sets automatically every time I put the truck in park?

 

excerpt from the 2023 owners manual;

If the vehicle is shifted into P (Park) on a hill, the Electric Parking Brake (EPB) may apply automatically. The driver may not be able to release the EPB using the EPB switch. It should automatically release when the vehicle is shifted out of P (Park).

So it sounds like it did not automatically release when shifting out of park. One of those features that is somewhat nice when it works, extremely frustrating when it doesn't. Is this an ongoing issue, or did it happen once?

 

I bought this vehicle back in April. I have never engaged the parking brake as I am never parked on a hill since I have owned it. Only in my own driveway which has a very slight incline. However every time I am parked in my driveway the vehicle has seen fit to engage the parking brake on its own even though it is an exceptionally slight incline. And every time I have started it and shifted, the parking brake will never and has never disengaged without having to step on the gas which causes the tires to do it burn out in my driveway.

 

What does the dealer say about the issue? You’ve taken it to them to have it checked to confirm whether it’s a malfunction or a user error, right?

 

I haven’t had time to take it over. I am a contractor so during the week is very difficult for me to be without the vehicle for any length of time especially right now because I am very busy. It will have to wait until I get a little bit of free time from work to be able to drop it off. In the meantime I can start making up a list of everything else wrong with it so I can take it in and have it all done at the same time. By the looks of it, will probably in there for a week. The last thing I thought I would have to be doing purchasing a brand new truck.

 

My 2022 Silverado does the same thing. Here's what I've learned, well, what I think to be correct. If the PB automatically sets, it automatically releases when you put it in gear. I THINK if you manually set the PB, you have to manually release it. Try it a few times to see if this is true.

Anyway, what I have found myself doing is when it automatically sets, I'm pushing the button about the same time it is automatically releasing, so I end up setting it! Or, if I think I need to set it, I find myself pushing the button about the time it automatically sets, so I end up releasing it! So, I just leave it alone and check that it has applied when I think it needs to apply.

The bad thing about something like this is it will EVENTUALLY fail, after someone has learned to depend on it. And then it will roll down the hill because the driver didn't check, or the driver will be so brain dead that he/she won't know how to set it!

 

Not directly related, but wifey’s Outback has the parking brake motor. It failed YEARS ago and is the subject of an extended warranty. After all these years the part is still on back order.

 

I have 2023 Silverado 1500 that intermittently self applies parking brake in driveway with slight grade. It will not release when put into "Drive or Reverse", nor when you hit park button. I need to apply pressure to accelerator to move vehicle before it will release. Vehicle was manufactured in MX delivered to in March 2023. It has 6400 miles. Annoying at best. I too would love to turn "this life saving feature off!"

 

Mine will activate the parking brake whenever I put the truck in park and it "rocks" after. It takes very little throttle pressure for it to release in drive, a little more in reverse but hardly annoying.

 

Is that the hill assist thing engaging?

You can't be suggesting that the OP go to the dealer without having his ducks in a row. And just so you know there is no reference to this in the Owners manual that I can find.
I have a 2023 High Country that I am having the same concerns with. Sometimes the Park Brake will set automatically when I put it in Park, and sometimes it doesn't.
There must be a fine line in the parking angle that causes the parking brake to automatically set. I know the grade of my driveway is not consistent, so depending on where I stop, sometimes it sets, sometimes not, major PIA.

That’s what a new vehicle warranty is for, but of course there no harm in asking. Which I never said there is.

But… Maybe we’ll never know what he did, if anything, since he hasn’t been here much since posting this thread a year ago.

 

I understand your frustration, I couldn't find anything about this "feature" in the owners manual. Depending on where I park in my driveway sometimes it sets, sometimes not. And when I push the button to set the park brake sometimes it has been set automatically, and then I am releasing it. The nanny's either need to do it, or not do it, just be consistent, and forget the built in Inclinometer.
