Hi folks, new 2023 sierra 1500 owner here, and my first GMC. Question about the parking brake. The times at which it engages automatically when I shift into park versus not, and disengaging automatically when I shift a reverse or drive, seem to be somewhat random. Sometimes it does, sometimes it doesn’t, and I have to manually do it. Are there any tricks here or something I’m not noticing or a setting somewhere? Thanks for your help.

mine works the same way, i have a steep driveway and sometimes i pull in i let it creep to a stop to see if it will roll backwards, most of the time the brake will come on and other times it does not and the truck will roll

Taking foot off the brake or just a slight touch of the gas pedal should release it if shifting doesn't.

I think GM is trying to keep owners from using the "parking pawl" in the transmission to hold the vehicle in place on anything other then flat ground. I have noticed the same thing.  If the ground if flat it won't engage, park on a hill and it will.  Also, I noticed if you're stopped at a light you can press the park button and then you can take your foot off the brake. The truck will stay in place and all you need to do is touch the go pedal and it will turn off the parking brake and you're off.

If you park on flat ground without applying the parking brake then get out and rock the vehicle back and forth the e-brake will auto apply. Happened to me several times.

No need to manually release the parking brake. Just bump the throttle once and it'll release.

I haven't completely paid attention but I believe if it auto-sets (due to an incline), it will auto-disengage when you put it in gear.  If you set it manually, it will disengage when you touch the gas, if you don't manually disable it.

I believe it senses went trailer is hooked up and will make you manually release the brake. This is how mine is. When I have nothing hooked up the parking brake will set and if I need to release it I put it in drive or reverse it releases, but when I’ve got my trailer hooked up I always have to manually release it. When I have the trailer hooked up it will set the parking brake no matter if I’m on flat ground or incline/decline but I have to manually release it.

I was confused about all this when I first got my 2022.  I went back and reread the Owner's Manual section about the parking brake and they describe all the ways it gets automatically set and released.

 

I don't really like it.  I have had situations where the truck sets the parking brake itself and then out of habit, I pressed the Park button (intending to set it) and unintentionally released it.

 

Part of the problem is having the same press-in button being used to set AND release the Parking brake. That's a very bad design. There should be a switch or lever that has an ON and an OFF direction that is not the same.  So if the truck turns it ON and I press the switch in the ON direction again, it stays ON (instead of releasing).

 

I doubt any GM design engineers read all this stuff here, but they should change it.  I predict they change it AFTER they lose a big lawsuit where the victim proves their faulty design caused a serious accident.

The whole refresh is a bad design in my opinion.  Wish I would have stuck with my 2020.

Piano black=sucks
Shifter is unintuitive (full forward should be PARK, not reverse)

This G damned parking brake automatically turning on.  Save a parking pawl, ride an e-brake?
Loss of space due to floor shifter
Front end's Chevy logo is up too high
Front end missing the turn signal lamps, independent of the DRLs isn't as nice looking

 

But hey.... we have a pretty screen

Adding insult to injury when the 'refresh' HD's finally arrived ( 2024 model ) the owners rant; being subjected to the stupid console shifter.

Has anyone had the parking brake disengage by itself as you are walking away from the truck? This has happened many times and it doesn't matter if the truck is on flat ground or on an incline.  I usually get about 50 feet away and I can hear it disengage and then see the truck roll up against the parking pin which eventually stops it.

Any help or ideas would be great. I've taken my truck to the dealer for this at least 10 times in 18 months for this and they can't find it or duplicate it since it doesn't happen all the time.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
