That's false advertising if I have ever seen it! Between engines spinning bearings and kicking rods out the block to transmissions that can't even make it out of warranty, GM should be ashamed of themselves.

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 that is wired to be used with the Pico.  This is for recall N252494000 which is still in "incomplete/remedy not available" status.  

 

Trucks with N252494001 are still the verify P0016 is not set, if not, switch the truck to 0w40.

 

N252494002 has been appearing as "open" on some VINs.  This one is the put an engine in it recall #.  The one we have that is currently already getting an engine actually has this recall as open status now so GM knew by VIN that either the original or the replacement engine are/were suspect and therefore it was given the 002 recall version and to put an engine in it.  

Thank you for posting these upates. I, for one, really appreciate you keeping us in the loop.

Do we really believe this has been fixed for the 25 model years? Let’s say your dealer wanted to do you right and traded you into a 25. Would you have concerns?

Don't see why not 🤷‍♂️

 

GM knows the window for the problems, March 1, 2021 to May 31, 2024.  Post May 31st 2024 they had the improved production in place for whatever concerns were going on.  Is it possible that one bad one could sneak out here or there?  Sure, can with any of the engines they have, but I'd imagine if one popped up that GM would nip any issues in the bud quickly after this whole fiasco.

So my engine build date is 21 Feb 26 ... Truck build date 03/21 and it is on the list.

Is the recall for Engine build date or Truck build date? My build date was 6 days after yours on 3/27.

Sorry to hear. That’s the next thing. Lots of opportunities for them to screw things up during such an invasive repair. I could never get dealers to do the simple things correctly let alone something like this. They completely destroyed multiple pieces of the interior on my Silverado fixing the rear window leak twice. And then the Ram “wing” of the same dealership installed a shock backwards on my other truck and destroyed that. $1200 repair they had to eat at least. 😂

I'd trade in a heartbeat! My local dealer has a 25 that's an exact duplicate to mine and I would not hesitate if they offered me a real good deal

I believe it is the engine build date. There is a sticker on the back of the left side engine cylinder head with the date code. The engine build date will precede the truck build date but not by much, natch. A few days, maybe a week.

Does it matter in terms of the recall?

My truck is on the recall list by the vin # and the engine built date is Feb. 21.

Per the NHTSA 25V-274 (N252494000) document....

 

"GM’s updated field data analysis identified a build period from March 1, 2021, to May 31, 2024..."

      OCI, not when but why?

      By KARNUT · Posted

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      By ShotgunZ71 · Posted

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.
