'23 down; massive oil leak | suv's don't get lz0's?

[steiny93]

Future inlaw's, really liked the wife's diesel denali so they bought a pair of them, one in a pickup and one in a suv (both diesels both '23's).

The pickup has been the usual new vehicle stuff; pretty solid, all happy in pickup land.
The suv just went down (sub 3k miles) with a massive oil leak (towed out of garage type of leak), dealer is thinking rear seal (or something) but they are stuck in a holding pattern for more intel from GMC as to what todo.

"I thought" the oil leak topic was an issue with the early 3.0's (lm2) and not the later 3.0's (lz0). But, it appears the '23 suv's get the lm2 and not the lz0 engine like the pickups get.
Is that correct?

The interesting part is these folks came from a competing brand, their first foray into the GM experience. Just under $200k into a pair of vehicles and the dealer is giving them noise about a loaner as they are looking at an unknown eta on the fix. These people aren't necessarily upset as they have other options, rather they are puzzled that this is the expected experience and people are ok with it.

Something to know about GM and diesels. We run into this with just about all of our vehicles with diesels in them. First thing they have to do is hookup the Tech Tool, screenshot all the update dates in memory. They want to make sure you have not tuned it at all, and if so, automatic denial on any powertrain related warranty work. I know Ford does this as well as Ram. Once they send it in showing there have not been any tweeks, they will get authorized to fix it. GM started doing this in 2006, Ford in 2012, and RAM I am not sure of, but the baby Cummins we have in a few trucks we have run into RAM checking them now as well. I have a Ford sitting at Ford for the past 2 weeks awaiting approval, they sent the screen shots in, just waiting for a nod that nothing was programmed on it.

Rear main sounds right. A friend of mine who works for an engine development company in MI said awhile back they were hot testing every 3.0L in dyno cells before they went to the line because of RMS leaks while GM was trying to find a solution. That was awhile back, but maybe the fix isn't perfect yet?

Do they actually think they bought Lexus service?

I’ve had both and I know the difference and expectations ……

Here's the article.. Is there a way to decipher what the date of the change was? Same with the historical error codes.. it's all there.

Have you read the marking materials for GMC lately? They are setting expectations incredibly high.

Some quotes from GMC
- THE GMC Sierra. It’s THE Truck.
- Another level of technological innovation.
- Enjoy first-class luxury all the way.
- Denali Ultimate is the most advanced and luxurious pickup in its class.
- and they just continue.

If you base your expectations on what GMC is saying, they are set very high.

In 2004 I bought a brand new 2004 Cadillac SRX V8 AWD. As they pulled it up it had a 1" dent over rear wheel well... so no car till Monday. They fixed that.

Then, within a few days I had oil dripping on garage floor. After 3 engine tear-down/fix over 3 weeks it was finally fixed.

Then, after a month a rear oil leak appeared. They said the differential gasket was never seated and floating in the body of the differential.

Over all - they gave me a rental 4 times in 2 months and finally got a working car. I didn't realize it at the time but this violated the CA lemon law and I could have asked for a different car. I wonder if this applies in this case - e.g. a lemon law activation.

it was not a good experience and this thread makes me think about all that trouble with was I imagined as buy and drive....

Fast forward today - I still have the vehicle, done many things with it, and even though it's been a pain with many fixes over the years it has never broken down or left me stranded. It's at 170,000miles but has recently become the 2nd car as we just bought a used 2021 Yukon Denali for towing reasons.

None of what is stated above applies to, or is implied to translate to, dealership/service expectations or experiences.......

I think there's an emotional aspect to the purchase of an American vehicle. Like Harley Davidson, no one buys an FLH because they're the best at what they do.

I would have them approach service manager about vehicle to drive if no satisfaction owner of dealership.
If vehicle is down for a while, they should be afforded a vehicle.

Nah.... I bought this vehicle because it the last decent diesel SUV out there along with the size of vehicle that met my needs. If Lexus made a Diesel big SUV, you could bet I would have taken a hard look at it too. This is the 1st GM vehicle I've owned since the 1990's. While a lot more complex... so far, the experience has been mostly positive.
I buy the best vehicle fit for the purpose... no matter who makes it....

Well, I'm pretty sure people buy the HD FLH for the same reason they buy the Yukon Denali diesel - There's nothing else like it. But with $200k spent on two new vehicles I'd think any dealer would do whatever it takes to keep that customer satisfied. Strange times in the USA automobile markets these days.

Have one, also a baby diesel, it gets double the miles that the denali does due to the interior being nicer.

Are you serious?

This quote doesn't speak to dealership/service expectations "Enjoy first-class luxury all the way."

What kind of mileage ?

mileage is very similar

it gets double the miles (usage) as the denali

It's no different than buying a highly touted top-of-the-line appliance, lawn mower, or yacht. It can be embellished as the best of the best but has zero to do with how its supported.

I have Wolf and Subzero appliances in my home. When I called for service about a year ago on my range? 6 weeks before they could come look at it and only Factory Authorized technicians can repair it....

I am serious. Sales tactics, and eventual support rarely go hand in hand....

Sales people aren't always the most truthful and the service dept didn't sell you the vehicle.. Often times, one needs to re-align their expectations with reality. And I'm speaking for myself as well.

Doesn't mean we shouldn't complain about it vociferously and let others know what to expect. It's false advertising. Ultimately, it's bad for shareholders, too, and should result in less vehicle sales. You can only pull the BS so long, before it catches up with you.

But yeah, there is a reason we only have one GM vehicle and we didn't waste our money on the "cache" of GMC, or High Country. Got only the Chevy trimline required for DMax, 360 camera, and panoramic roof (plus I went for the RST style). Wish I had paid more attention to the delete options. I could have done without descent control.
