Was it able to crank and start at all?  I think I remember some on here with some crazy error codes like that due to extremely low or discharged battery.   I've got a 2020 6.2 Sierra as well

I have to say.  Suttle Motors is not a bad place to do business.

Mines got a build date of 7/20 wonder if I’d be affected? 6.2 in mine also.

Yea the bulletin says June 1st thru Sept 15 production. 

 

I have 6XX miles on mine now and 20.3 engine hours. These seem to be failing right out of the gate. (197 and 316 miles in here)

Mine is a USA build.

So is this something I should mention to my dealer or let it play out see what happens? My truck is a ft. Wayne Texas truck it says on the door. All 6.2 motors are assembled in Tonawanda I think?

I would assume your dealer would not be of much help unless there is an actual engine light or running issue.  I guess I would be interested if they had a more precise breakdown of the issue by VIN #s or Mexico vs USA builds or the like...Which I guess is already pretty broken down by 6/1-9/15 builds of all V-8s Camaro, Corvette, HD trucks..

Be nice to read more in depth info on this. Like you mentioned maybe just a bad batch of valve springs. Maybe it could be traced back to vin #’s. My truck has 2700 miles been pretty solid few small issues like small back shifting issue and lifter tick that has seemed to disappear. Thanks

Yea with 2700 miles I would probably guess your in better shape, a couple in the corvette thread were like 50 miles and stalls.  I think the highest mileage of failure in the corvette thread was like 450.  

Still, yea the more we the consumer who spent alot of money on these can know the better.

That is troubling to hear... I'm really hoping they extend my warranty to 100k miles like they did for the OP.

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
