2021 Denali High Miles

[todayusay]

If you haven't already, I'd see if you can get a GM service history report on it. If nothing else - peace of mind one way or the other.

We had a 21 AT4 - bought the last day of 2020 - sold it in the spring of 22 with 45k on it. Had a lot of mickey mouse stuff keep popping up but never stranded.

Almost all 21s had to have the extra vent hose for the sunroof to drain properly - added after the fact. If that hasn't been done (there's a TSB on it) I'd check and see if your dealer could "proactively" fix it before you end up with water in your floorboard.

Air ride is the only thing else I could see potentially having a problem with further down the road.

That's high mileage?

Geez. Cars are so disposable any more. Sad times we live in. Back in my day, as with the '01-'14 generation of trucks, "high mileage" wasn't until closer to 200K.

It's pretty high mileage for being 2 years old. I'm sure that's what he means

It is “high” for a 21…30k/year…

I didn't read it like that at first, but that does make more sense. Apparently, I don't have an accurate idea of what normal mileage is. I drive 60K a year and have always kinda had it in my head that 20K a year was normal/average. Add in a vacation road trip or two and you're at mid- to high 20s. Of course, with some of the issues this generation has, one might consider 30K high mileage and near end-of-life.

A four year old vehicle with 250,000 miles is far more likely to have been well maintained than a vehicle that hasn't yet hit 250,000 miles in over 10 years.

Too many Lincoln Town Cars & Clown Vickys are STILL running around NYC as livery cars.
Every single one's got at least 250,000 miles and counting ...

Check the engine hours, and if possible, check the engine idle hours.

1676 hours of runtime

 

[Marky Dissod]

60,000 miles
1676 hours running
35.8 MpH (the higher the better, til it starts to strain credulity.
Even without knowing engine's idle hours, not bad at all.

Service the ATF. If AWD or 4WD, service the front differential too.
Basically, just maintain its parts anywhere between 20% - 33% more prematurely than the manual suggests.
The manual's writers want that vehicle to be unserviceable as a whole in 10 years or less.
If you don't agree, maintain it as such.

My 21 Tahoe Z71 just passed 71K miles 1782 hrs

2020 Yukon XL Denali: 93k and counting.

Baloney.... I have a 7-year-old Jag that only has 39K on it and it's in pristine shape and still gets annual maintenance. Same vehicle with 139K on it? I wouldn't touch it....

Which one would you rather buy used?

 

[Marky Dissod]

Jaguar ... which Jaguar? Which engine?
Think about what I said:
A vehicle HAS to be well maintained to accrue 62,500 miles a year for four years, or it'd've broken something major beforehand and never made it that far.
Most owners of vehicles driven so, have maintenance records to prove it, a critical underlying concern.
The other concern would be the price, which is obviously MUCH lower at that mileage.

I cannot afford a 7 year old Jag - Jag what? - with 40k miles, in pristine shape with annual maintenance.
Most people who are selling a Jag - Jag what? - with 139K do not love & did not maintain it well enough; that's got something to do with why they're selling it.
It stopped 'being a Jag (what?)', and likely was neglected for the latter half of its life.
I likely cannot afford to fix a 7 year old Jag whatever that has been neglected for 3.5 years either, so I won't buy it.
Also, Jag likely stopped designing their cars and parts to last much more than 150K - except MAYBE their turbodiesels?
Are their any 'prestige' brand cars left that are still mechanically sound after 150,000 miles?
Think I'd prefer an old M-B W126 to anything younger.

Since this is a Tahoe / Yukon / Suburban forum ...
I will not buy any GM vehicle without definitive proof of when the cylinder deactivation mode was at least disabled in the software, preferably physically deleted, in addition to the rest of the maintenance records.
When this Tahoe's engine finally fails, I may prefer to replace the engine instead of buying a younger GMT900.
