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.

      Fluid Change Questions

      By Z45 · Posted

      I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

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

      By Atlas · Posted

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.

      2027 GMC Sierra: Official Discussion

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.

      2027 GMC Sierra: Official Discussion

      Yes, you must have seen my thread on the Blazer. HOT GARBAGE, but I love them anyway. I'm convinced every car guy has a soft sport for an S/T series somewheres. Probably even a Panther too, if I'm being an honest car guy. That doesn't mean they aren't junk. And they definitely don't get better with age. I sometimes play with old cars, but that's by choice. I don't rely on them and they aren't my everyday fleet.   Derek plays the common man on Youtube and that's no doubt where he started. Now he has Youtube money (and Motortrend, etc). You think his crews and his wife ride around in old beaters when they're chasing him and his wrecks across the country? No he's got newer and nicer stuff for that, you'll see glimpses of it in the footage.
