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.

Yea I hope they do for you. Think with the low miles that your had to have this issue they would do it for you no prob.

      Trading 7.3 (Godzilla) for G.M.C gas

      By KARNUT · Posted

      It is a company truck. Not under warranty. Both companies I’m involved with usually buy trucks that are discounted when looking. Except what the owners drive. Being retired and minority owner. I don’t drive a company truck. If they have the new GM gas engine it would be in a service truck.

      2026 sierra bad brake controller

      By flattop · Posted

      Update!   Had the dealer look at the issue. First tech says no problem?? I said there was no voltage on the brake terminal on the 7 pin connector! He said he did not know what pin I was talking about. So they bring out a seasoned tech and I explain to him. He attaches a VOM and has me push the brake, and sees no voltage!!    Tom, the seasoned guy says lets go back to my service bay and look closer. We discover thru his on line system that the controller is a "smart controller" as it needs to detect a trailer connected before the brake voltage is allowed to the 7 pin connector!!! He also showed me a GM bulletin stating some trailers with LED lights have such low resistance the controller wont recognize them!!! I was thinking WTF, but thanked him for bringing me back into the service bay and explaining this all to me. He also plugged in a trailer simulator and it showed the brake controller was indeed working.   After my dealership visit I hooked up to an older camper with standard 1157 lights and the truck did connect and the electric brakes worked great!    Not to sure what I have to do with the equipment trailer with LED lights, I cant tow it with no brakes.   Why did something so simple for many years have to get so complicated!

      Do find out as that would be interesting if they have been using any L8T engines or for that matter have been running any of the Ford gas 7.3 to see how they have been panning out.    I assume your nephews engine replacement was on his dime as the regular warranty would have long past unless he had some form of extended warranty that covered such events. That shows though and may depend on the year of the build that failures are occurring with the valve train well beyond the warranty distance and more than likely so will others have that sneak up on them.

      I realize this is an old post and its probably been talked about since then on this forum and I may have mentioned it myself but the Chev multi flex tailgate on the HD trucks are all aluminum so there is that one item that I am aware of on a current GM HD truck that is aluminum but if its the standard tailgate then its still a steel unit as far as I am aware to current 2026 model year.

      Gas Prices

      By Chuck FB · Posted

      I am surprised it didn't pop back up some just in time for the end of school/summer holidays and July 4th time period. Here in Alberta it hit its low coming off the high back a week before the end of June or so and has been creeping back up some and would equate roughly to around 20 cents per gallon increase. Of course there are various factors and one is the games they typically play with wanting to capture that holiday vehicle movement but also our government directly causing our Canadian dollar to drop ( a polite way of explaining the real picture ) causing our prices to go up rather than continue down like it should have, and even though we are sitting on the crude.
