Ordered a 2024 RST.. WHAT DOES IT MEAN...

[Badbird2000]

So, i ordered a 2024 RST December 29th, 2023. Ordered it with the 6.2, max tow package, Glacier Blue, all stuff i wanted. Checked in with my dealer this week, no progress since it was submitted. he told me the 6.2 is on constraint. What does that exactly mean? Limited number of 6.2's being pushed out, no one gets a 6.2... I mean, they are still pushing Escalades out the door, assuming they all aren't getting the diesel motor. I know of the problems with the 6.2 and rod bearings. I would hope they would have fixed that by now.

Why not look on a lot somewhere, not like there are these out there options with chevy trucks these days. GM is literally today package 1, package 2, package 3. They probably have a few thousand Glacier Blue RST trucks with a 6.2 sitting on multiple dealer lots all across the country right now. I would also think you would get a better deal taking a truck already built off a dealers lot then ordering it from factory.

I can't find one with max tow package. I do searches about once a week still, maybe 4 or 5 pop up in 300 miles, and they are white, or not half the other options i want.

Rod bearings?

Jesus Christ I get tired of hearing about all these unsubstantiated problems. Rod bearings? Cmon man where do you get your info from Twitter?

Constraint is a pretty generic term. Could mean GM can not get any of one of hundreds of parts to assemble a 6.2L engine, could mean factory problems where the 6.2 is built, could be many other factors affecting RST production with a 6.2L engine. Have you gotten confirmation that Chevrolet has received your order or has assigned a production slot for your truck? Maybe you need a better answer from your dealer about why the 6.2 is "constrained". Cadillac Escalade production has nothing to do with Chevrolet RST pickup production. An Escalade costs about twice as much as an RST and probably generates twice as much profit for GM.

 

Let us know what your dealer says about this constraint.

I'm guessing you won't get your truck as you ordered it since I had seen the glacier blue color was already built out for the 2024 year. Constraint is usually a supplier issue, but in this case, they've decided to use the 6.2 in the higher trim trucks such as High Country, GMC Denali's and Caddy's.

Nope, my buddy who is a tech at the dealer i go to. He had a brand new Suburban in the bay next to him with under 1,000 miles with a 6.2, the number two rod was burned up. He said they see a handful a month, mostly low miles, under 5,000 miles with the same problem.

Hit up the GM technician pages on Facebook.  There's 4 that were just posted this week.  2022 and 2023 all low mileage.  Our sister store had 2 of them lock up last year.  Both under 10k mi.  Rod bearings.  One was a Yukon Denali, the other a Silverado LT Trail Boss.  The Denali locked right up on the guy doing 70mph on the highway.   

 

Bulletin on engines seizing - 23-NA-170 1..3 (nhtsa.gov)

 

We can't even get the L86 from 14-20 for replacements from GM.  Lack of cores because techs are re-assembling the cores to ship back and exposing a casting flaw.  The flaw?  The blocks are cast thinner on the outsides vs. the old LS 6.2s.  If the techs don't thoroughly clean out the head bolt holes before putting the heads back on, they can hydro lock the hole and it windows the block.  1200+ L86s on backorder too right now.

Here's the picture from that bulletin on the L86s.

Actually it is pretty well known to be an ongoing issue right now with the 6.2 as proven above me.

Good Lord, we get tired of hearing about all of the unsubstantiated support despite GM's continuing failures. C'mon man, where do you get your uninformed ignorance from??

I should clarify that this is happening only during engine core reassembly at the dealer level.  But yea, I assume to save weight and costs, there was some metal thinned out to the castings.  But they are definitely losing good L86 cores and its not good.  Plus they upped the cores I've heard to about the price of the long block.

Well I don't work at a dealer. First I've heard of this.

I'm sure it's just as bad as the lifter problems then.

So this happened to how many trucks? 1 in a thousand? Big deal.

It's far more than a thousand, my guess would be in the 10's of thousands. Most likely whatever facility created the castings wrong and GM has always proven to let it try and get passed warranty and fix the broken ones then throw parts out for fear of premature failure. Sucks but luck of the draw applies here, it certainly is a big deal to those with broken trucks, and GM under constraints for the needed fix.

 

Would you be happy making payments on your truck but stuck driving a rental Nissan Rogue for 3 months or how ever long it will take for GM to produce new engines? I bet it would then become a big deal to you.. Never mind the fact that now you are paying top dollar for a truck that had it's engine ripped out by Tony at the local GM dealer...
