2022 YUKON DENALI 6.2

[Fernando Escobar]

Thanks for the replies. I bought this truck cash at 12k miles from the auction. So warranty is out the window. It’s a risk I take. Anyways , at this point would yall replace the engine with a used engine or would yall rebuilt the existing engine with upgraded parts/specs? I have access to L87’s wholesale. I can replace it the engine with another one but it wouldn’t make sense if I’m going to run in to the same problem again. Or if you were to buy a used engine , what would you change more or less to avoid this factory issues?

used is probably cheaper but with this year engine luck it might be in the same shape. I prefer to rebuild to know what you put in it. so it really depends on your budget and time. I rebuild these engines but I take my time and for some customers time with out their car is valuable so used or new engine it is for them.

Lol and neither have you. Go ahead and try getting warranty service on a branded vehicle. It all has to get approved through GM - not a simple “oh you’re under X amount of miles and years so you’re g2g buddy!”

If it wasn’t enforced, then a lot more people would be buying salvage vehicles.

you are correct in that I have not done it with gm but have with toyota, not a word was said about it not being covered.
so it remains to be seen..... not just guessing

I’m not guessing either. I had a 2020 Ford Expedition. Took it to get the battery replaced. They called me 30 minutes later to ask me if I knew that the vehicle was branded(saw that I had temp tags). I’ve owned over a dozen branded vehicles. Friends and family have owned even more. Everyone knows that you won’t get warranty service if you have a salvage title.

gm doesn't zap anything, they plug in a obdii reader that pulls codes active or historic and the service writer prints it out. doing that also provides the vin & mileage
that's it. so unless someone went into the gm service computer and flagged the vin, they have no clue

When was it the last time you went into a GM dealer and saw this? I took mine in last month to get my parking sensor retrofit completed. First thing they did was come out with a tablet and scanner. Scanned the barcode on the B pillar right away. 100% sure that GM runs the vin etc before any kind of approval.

Even if they aren’t scanning anything, they still have to get permission from GM to warranty a repair since GM are the ones that are paying for it.

Back to the engine topic, I think that a 6.2L from something up to 2020 would be fine. I'm not aware of any changes that would prevent it from working in a 2022 year.

Or, do as another guy here did and put a 6.6L on it from an HD pickup. With HP tuners, you should be able to copy the spark map from a 2500hd with that motor, overlay it in your current ecm, and turn off DFM in the fuel economy tab. You may have to have someone tweak it for a different gear ratio, or you may be just fine.

I've compared my 2008 6.2L to a 2014 6.2L, and a 2015 6.0L. The maps aren't WAY different to the point of unusable. Just some tweaks from 2008 to 2014. The 2015 6.0L map is similar, just less spark advance.

That being said, if I ever run into that problem in a 2017-2020 model year, I would highly consider the 6.6L swap. The exhaust on a 6.2L should be big enough to work appropriately, compared to a 5.3L. The loss of vacuum assist pump for the brakes would be a god send. And a motor tuned for torque on 87 would be nice. I think it would be a dynamite setup.

Maybe some dealers do it differently mine scans it thru the obdii port (wireless) and then they print it out to give to the tech. I was there a week ago. The dealership has been around almost 100 years. Not sure how a dealer is going to get vehicle codes from scanning the vin thru the window or door sticker, that's not how it's normally done. Maybe there is some other wireless method or onstar, etc but as far as I have ever been informed as long as whatever is going on is a stock part and it's within range of warranty they just do it, they don't question much. I guess if you took it in there all smashed up they might say it was caused by the accident or something

Might be different in other states the only indication of a salvage vehicle here is to look at the title, theres no sticker or label or special tags or anything. Or of course checking dmv, Carfax etc. in general I don't think my dealer runs a vin thru DMV when it hits the service drive

The service writer doesn't scan for any codes, the techs do that. The service writer shoots the vin sticker with the little gun to help fill out the ticket because that automatically fills in things like vehicle year, made model, engine/ trans combo etc, they then type in all the "customer states" messages the techs laugh at in the back. The service writers don't give two craps about what codes are stored in the computer, it's not their job to.

I guess that's why my dealer's been around almost 100 years cuz they do things the right way and they absolutely scan it for codes and then they print it out. You can look at it if you want to or they just staple it to the work order and give it to the technicians. When they connect the OBD2 device. It also lights up every light so you can see if one is burned out or not, brakes reverse blinkers headlights and the dam thing, picks up some codes even if you cleared them already I was surprised it did that

So then "your" dealer does it different than every other dealer is the US.

I've lived all over (side effect of being the military for 20 years, you move a lot) and had several different brands of vehicles ranging from Chevy and Ford to Cadillac and Mercedes, never once seen a service advisor do anything other than type in the ticket, tell me where the customer waiting room was and maybe offer me a bottle of water.
...

 

[DontTaseMeBro]

All in all, it doesn’t matter how they do it. The bottom line is that they have to get approval from GM to warranty anything because that’s who’s paying for it.

i guess so, they have done that for as long as I can remember they even upgraded the system about 3 years ago, the new obdII readers are about 9" long, wireless. the old ones were wireless as well but only about 4" long.
I am not all "pro" dealer they all get you for every penny they can, but the dealer here is pretty good at there job
maybe that's why they get all the business they are a chevy dealer and there is a gmc dealer right around the corner from them and that place is a ghost town by comparison.
I went to the gmc dealer once in the last 25 years, they were dick's so I never went back.
And they will install customer supplied parts, I guess that's not a typical thing either.

Dealers only have to get approval from the regional rep (dealerships are independently owned, the regional reps are GM/ Ford/ FCA employees) if the dollar value of the warranty repair exceed a certain dollar value.

So if the warranty repair is cheap, the dealers can just perform the repair, submit the paperwork to GM,and expect to be paid. If the warranty claim is expensive, then the dealer has a choice to make, do the repair and risk it, or wait for approval from the OEMs regional rep, most will wait for approval.

In this case, it’s probably an engine replacement so it’s gonna have to go through GM.

UPDATE. ENGINE WAS DONE FOR. Opened up the oil pan and it full of metal shavings. The crankshaft , and bearings were extremely damaged. Turnaround time was way too long to rebuild the motor. so I’m buying a low mileage L87. Just strictly using 5W-30 or 10W30. My trusted mechanic said that he has been through several 6.2 at his shop , all them due to the incorrect oil. Per him , he said as long as I use 5w30 or 10w30 the motor will run long. Thanks for the help and advice guys.

The dealer I have been working with for years is similar to the one you describe.

When a vehicle comes in they scan the VIN then when it is ready to go to service bay they run vehicle through a gate that scans the exterior and underneath before service. The computer will analyze the pictures and give a report of what it sees, if you have scratches, dents or anything out of the ordinary. They even text the pictures and report to me so I know they are working on it.

They also install customer provided parts, tires and wheels. They also will price match tires if they can get them. Also they usually wash the vehicle after service if you /they have the time.

similar here they will price match tires, etc I think when covid hit and then the chip shortage right after there lot was pretty barren for a while and I think the car wash guy got dropped but I think a majority of the employee's are still there, they had also dropped the shuttle service for a while during all that but the service has been back again for a good year or so. you can take your vehicle there in the morning and they will drop you off at work or at home and then pick you back up either after work or when your vehicle is ready
a number of dealers around here do that, not sure if that is a common thing elsewhere. I can only assume it is.
And they will of course do a courtesy free inspection, when they are charging $479 for brakes I guess that is worth there time lol.

Wonder if he recommends 5-30 in the 5.3’s?
