Not on my 2016, all the lights come on except for the headlights, like turning on the parking lights.

Well, yeah, that's to be expected of parking lights.

My 2018 has an anti-sleep function and built-in seat and steering wheel massage.   To activate the anti-sleep function, just get up to cruising speed on the highway.  The vibrating and deep

I couldn't figure out what what going on when my high beams started turning on by themselves, I later found out that if you double tap the brights it turns the auto high beam feature on/off.

No it’s just from turning on the fogs only. Same for 2018.

That's what I was trying to say, when I turn on the fogs the other lights come on except for the headlights, as if I turned on the parking lights, but I didn't.

Yessir. Agreed. I was clarifying for the gentleman’s post in between ours that the trigger is the fogs.

Welp, yesterday I opened the passenger side door to work on something while talking to a friend and hung out for a minute before deciding to remote start my truck. Hit the lock button and then remote started it.  Reached across and put my keys in the ignition. Stood chatting for a moment and when I went to walk around my truck to get in, I closed the passenger door. An hour of idling and waiting later, AAA to the rescue. 

There IS a remedy for this, actually. I have two keys and the only time both keys are inside the truck, is when I'm inside the truck. I try to always keep a key in one of my pocketses.

New to this forum, thanks everyone for your input.  Here’s one I experienced last fall after crossing the US/Canada border in my ‘17 Sierra SLT - switching the speedometer from MPH (US) to KM/H (metric) also changes ALL other displays to metric.  Cabin temp, transmission temp, and outside temp displays all go from degrees F to C, tire pressure and oil pressure go from PSI to KPa, fuel economy goes from MPG to L/km, etc.  I ended up toggling back and forth often to stay within speed limits and still have an idea of fuel economy.  I was pulling a travel trailer and L/km didn’t help me much.  Thankfully, it’s pretty easy to swap between modes.

I read all 29 pages of this thread...  here's what I would like to know:

Several people in here have mentioned how to turn Grade Assist Braking OFF.  I want to know how to turn it ON in my 2016 Z71

 

I drive in rush hour traffic down a significant hill daily.  I'd love for this feature to be able to be activated the same way I count with the low speed hill climb...   But sadly I don't see a way to do this.  I'd love to be able to be rolling at 20-35 mph down a grade in traffic and set the grade assist to that speed going down the 1.5 mile hill instead if constantly hitting my brakes.  Shifting into manual helps some, but by no means does it do what the grade assist.. but ONLY on hot days (I think brake temp factors into the equation).  I wish someone had a sequence to activate it on my commute daily!

 

Have a good day all.

Stay safe.

So there’s grade braking which as far as I know will only activate at a certain grade and a certain speed (I don’t know what either of those are tho but I have seen it turn on driving in on one particular off ramp near me. I can take note of the grade and my speed next time I see it and let you know. It doesn’t happen all the time tho.

The other is hill descent control which the all terrains (and I’m not sure what other models) have. That can only turn on below 15 or 20 mph and I think is not what you’re looking for. But that is condition and button activated.

From just driving experience & in no way backed up by technical knowledge I believe the grade braking only functions above a certain speed & likely measures time with brakes applied vs speed reduction (or lack thereof).
All it does is change down gears as far as I can tell so you are as well to stick with your manual shifting.

TFL Truck on you tube test grade braking and I believe GM had the worst scores , if you put it in tow mode its active ,But I may be wrong , I only had hill decent pop on at low speeds

Here’s the thing. It only activates for me in San Diego when it’s > 85* outside, and as I’m going down the grade I’m lightly dragging the brakes. The DIC Chime’s and says grade braking activated. At this time, it maintains my current speed with no throttle input. If I hit the brake, it disengages. If I throttle up, i speed up, if I let off it will hold the speed at which it activated. It’s a totally different experience than putting it in M3 and using the throttle to maintain speed. I wish I could get to my target speed then select cruise control, and then do something like hold down the hill descent braking lever in my truck to force it to activate the grade assist feature at the speed.

I could be wrong but I thought putting it in tow/ haul mode activated grade braking.

Grade braking is active by default. You hold in the tow haul button for like 5 seconds to toggle it on/off. It is then reset to on with every key cycle. The owners manual is great for things like this you know....

HDC is different and separate from grade braking. HDC uses vehicle brakes and grade braking uses the transmission.

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
