So, lately I've been noticing my truck (2015 Silverado 1500 5.3L V8 Crew Cab) has been sluggish while accelerating. Not all the time; it is intermittent. Could be from a stop or from a crawl usually. I'll hit the gas and I'll feel like a hesitation and no "oomph" and then it feels like the engine seems to lurch/stagger and then I'll get the regular acceleration and then it seems to be a non-issue.

 

Any thoughts would it could be? Truck just rolled into 50,000 kms and I've got a CAI and Borla exhaust - if it matters.

 

Thanks!

My '16 does the same thing. Once the engine gets around 2,500 rpm the stumble/stutter goes away. Way to go GM, make a $50k truck run like a $500 jalopy with a cracked distributor cap on a rainy day. I'm ready for the day the warranty is up so I can get a proper tune.

I want to tune mine too; waiting for the same reason. No point in throwing out the warranty by doing a tune early. I drive my dad's 2012 Silverado and it doesn't seem to have this issue...

Jack Nicholson said "You can't handle the truth" The truth is that the torque management system is keeping you from roasting the rear tires at every takeoff and twisting the driveshaft plus grenading the transmission. At least until the factory warranty is out. Thanks Jack loved the redrum movie man.

+1 on the torque management. sometimes i feel as if the torque management is more intrusive and then other times it feels as if its more cooperative

I wouldn't say I'm driving aggressive at all, yet I can still feel a significant difference between my truck and my dad's older Silverado which doesn't have this issue.

I have a 2016 Chevy Z71 with the 5.3. I added the Airaid MIT with the air filter. I disconnected the battery and reset the computer and have been running the truck now for almost a year. Just seems like a lot of the time that the transmission shifts wrong and is to high in gear. Really no get up and go. Anyone else have this issue?

The trucks throughout GM's history have the absolute highest warranty claims submitted. Is there lots that is legitimate, sure! Is there lots that are abuse, absolutely!

 

So, of course the older trucks don't feel this way because they aren't made to feel this way. The 14+ have the torque management software. GM is trying to reduce warranty cost with this addition. It is normal practice for any manufacturer to do so. Reducing cost, more in their pocket. Does it suck? Sure it does. Is there much we can do about it? Not unless you get it tuned. This problem is bigger than any dealership or even this forum. I suggest people get on the phone with GM headquarters and complain. Don't call the GM customer service line, they don't even work for GM. They are Hewlett-Packard employees that just take calls and read from a script, that also saves money for GM. Now, me personally, I love my truck and really don't let the torque management bother me. If it's that bad for you, go try another brand and see if you like it better. Can you imagine if any manufacturer took every single persons opinion into account before a product was launched. Nothing would ever hit the public. Mass produced vehicles will have their faults. Personally I think GM is one of the better ones when it comes to recalls and service bulletins and keeping customers in the loop about changes.

A little dirt, paint strip in the road, moisture and an empty bed and if you don't have posi ..... lots of HP to get to the ground and TM. If you tune it out you be amazed how these trucks perform.

I have the adjustable pedals, so pretty sure that won't work for me. I also didn't feel the flex in the pedal either.

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      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.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
