2016 Silverado 1500 5.3 8 speed

so yesterday coming up to a light, doing about 50, someone crossed into my lane as the light turned red. Stopped a lot harder than I like but when I did, the truck just turned off, only the engine all of the electronics stayed up. It refired so I pulled over and just checked fluid levels as a precaution. everything was fine and no issues since. Anyone else ever had this happen or know what might be the issue here

The only time I had this happen was in a different vehicle that had a cylinder head issue. Not trying to raise alarms by any means; it's likely an apples to oranges scenario, mine vs. yours.

My friend had this happen to him when someone ran a red light. He smashed his breaks as hard as he could and when he stopped his truck had shut off. It started right back up. Maybe it's some kind of safety feature? Btw...truck has never stalled since.

If they have a vacuum booster for the brakes, slamming the brakes will suddenly deplete the engine of vacuum and screws up the air-fuel mixture...I had older vehicles do this, but it's been nearly 30 years since I had anything with vacuum assist brakes.

The vacuum has nothing to do with the air/fuel mixture. This is calculated by the ECM from oxygen sensor readings and yes, the vacuum is supplemented by the vacuum pump that runs on the belt from the crankshaft, it isn’t electric.

Ok, so it may not affect these newer EFI engines, but it will cause stalling when the engine is used for a source of vacuum...again, been out of a vacuum brake deal for over 30 years.

 

My bad, I won't try to help again...

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
