I switched mine over to the 0W40, my reasoning is since the 6.2 engine in the Camaros and Corvettes are using the 40 weight, and the truck engines use the same bearings.  Also GM is using the 40 weight for this recall.  Mobil 1 makes a 0W30 Dexos approved oil that a guy could use, as well the 5W30 is used in Europe in these engines so I don't think you can really go wrong with any oil you use, I just don't feel comfortable with the 20 weight.

the real issue here is Metaldyne Performance Group who supplies most of the powdered metal forged and machined rods ASSEMBLED by Tonawanda.  As recent as 2021, JD Norman Industries sued Metaldyne over

Update(s)   GM sent dealers a new special tool to use with an existing tool, the Picoscope (fancy high end oscilloscope plus a whole bunch of other fun stuff it can do).  Its a knock sensor

Just wondering about all the 6.2s in this recall range that failed after the original warranty and the owners had to pay out of pocket to repair them. Do you think GM will help them in any way?

Yes, if the individuals file for it like I did with my 2.7 emissions pump issue.

It says so right in the recall, so if you read it, it tells you how.

I have not yet received my letter in the mail and am the original purchaser, so I'd expect that to be arriving soon. However has anyone had their local dealership cold call them to schedule a service appointment regarding the recall?  Just received such a call about an hour ago, but wasn't able to answer so they left a detailed VM and extension to call back.

Mine called me then texted me days later. I finally called on Monday and scheduled it for Friday. Figured even though I changed my oil about 1500 miles ago I might as well get this out of the way. I needed a couple of warranty items looked at anyway.

Recall letter wasn't going to be mailed out until June 9th per info previously in this thread. It is also a staged roll out so not everyone will receive it at the same time so as not to overwhelm the dealers.

Please let us know what your result is after Friday. I'm interested in knowing if ANYONE, who has not had an otherwise obvious engine issue, is really found to need their engine replaced based on the Picoscope test.

Is someone going to start a poll on this just to find out how many passed and failed including year and mileage?

You're nominated. 😃

 

A member on the F150 Forums did that with the axle bolt failures for over a year. Lots of work.

My friends 2024 Yukon 6.2 with 12,000 miles went out 2 weeks ago. She wasn't even aware of the recall. It was making a terrible rattling. Called the dealership from the side of the road asking for a tow. Dealership asked is it drivable? Said technically yes, but it's not going to be pretty! As instructed she limped it to the dealership, who confirmed 2 days later that motor needs to be replaced. 

 

Dealership placed them in a brand new Acadia for a loaner, but this family has been buying trimmed out cars from this particular dealership every 2-3 years for a long time... So they likely get special treatment. Dealership says expect 2 months on waitlist..

 

Our 2021 Yukon 6.2L continues to run just fine, about to hit 70,000 miles. Recall says remedy not available, so we haven't gotten our pico test yet.. 2020 Sierra 6.2L (not under recall) at 80,000 and no issues (knock on wood with crossed fingers)..

Thanks for posting this. I'm concerned that if mine needs a motor that I end up in a loaner that won't be able to tow my bass boat, which is the whole reason I got this truck to begin with.

your future is my ecodiesel if you get the 0w-40 oil.  138,000 miles just roasted the rear main most likely based on noise next to the bell housing.  caught it immediately with the "new diesel knock" which isn't that easy to catch being a diesel.  drove it 60 extra miles to get the forbidden glitter on new oil and filter, jackpot bingo card on the glitter, she's dunzo.  as a matter of history, stellantis did a recall on the ecodiesel to reprogram the transmission shift points to removing low rpm lugging on the crankshaft and main bearings.  they also changed the oil weight to 0-40.   i didn't do oil analysis on it but i caught it immediately.  there was no extended warranty offered by stellantis and no engine replacement unless you were already under warranty.  i had 120,000 mile warranty and she gave up at 138,000.  2018 quad cab ecodiesel for sale, needs a bottom end rebuild.  few shops line hone them and put in oversized and wider bearings, coat the pistons, and use superior bearings from germany than the ****** ventormotori used, trash bi-metal.  top end, cam, all likely fine.  no rust.... and nobody will want it.

 

proceed with caution.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

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

      By Atlas · Posted

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
