Thinking of selling my new 6.2L Denali...

[PPV_2018]

Theres more than 39 complaints of engine failure on this forum alone. I guarantee its in the 100's of thousands of failures...

You guarantee? How could you guarantee something that you can’t prove ?

Hundreds of thousands implies multiple hundreds.. like 200k+

200k of 800k is 25%.. if a quarter of T2 gen trucks had already suffered engine failures then every day when you got on the interstate the shoulders would be littered with broken down T2 trucks like soda cans and candy wrappers

If there were 1000 complaints on the forum, it is still closer to 39 than 800k.

What weight oil would you consider for the 6.2

There's no way there are only 39. My engine just let go at 34K miles and I know for a fact I'm not on that list of 39. The 39 complaints are 39 owners who filed formal complaints. I was trying to figure out how I put my name on that list but no clear answers at least on the internet.

I think we’ve had probably well over 20 of those failures reported just here alone. Heck, mine had its engine replaced before I bought it.

For all the 6.2l owners that have "6.2l Range Anxiety", not how long between fill up, how long between engine failure, Suggestions for "Range Anxiety"

I am right there with you. My 22 is in for an engine replacement and I am debating on whether or not I keep it. I was on the fence of buying another truck, but this puts me in more of a position to give it strong consideration. My biggest problem is not knowing the full scope of the issue and which model years are most effected by the issue. Because I would also be looking at a 6.2l truck.

Normally I would agree that such a move is a rash decision. However there is a disquieting number of folks who have had a second and even third engine fail.

There is no dealer out there regardless of manufacturer who is having techs clear 16 hours on an 8 hour actual time with warranty jobs.

I literally hang out and drink with a dealer tech occasionally that gets 12 hours of pay/ day working anywhere between 4-8 hours /day. And AFAIK he doesn't discriminate between warranty and non-warranty, he takes whatever.

His dealer has a board that the service writers put the job paperwork/ keys on. The techs go up to this board and pick the job they want to do (assuming they have the appropriate certifications for that job). And its first-come -first pick.

Dude gets to work between 9:00- 10:00 in the morning, goes up the board , grabs whatever jobs are left that no one else has picked (which are usually the least desirable), rushes through them to get his 12 billable hours that day (because that's management policy, max of 12 hours billable/ day), then leaves. Sometime he leaves at 2:00pm because he's maxed out his billable hours for that day,.

Blame whomever you like for the the way it is,,, but there is no troubleshooting, and no understanding, and really no thinking about the actual issues the vehicle are brought in for happening,,,, there is only following what the screen says.

Well, that may be how he and his colleagues work. I know it is not that way at every dealership. Here's the thing:
-At some point, if the service completely sucks, and people cannot reliably get their vehicle fixed at a given service shop...they ultimately will go elsewhere.
-Now, is it possible that this particular dealership, where your friend works, has enough business, and GM has enough issues that this ship will stay busy infinitely, yes.
-But, when the surveys get back to GM, and GM decides this dealership has major issues w/ Customer Sat...then maybe things change. Maybe they dont.
-I personally have used a local, smallish town dealership, where the peple have pride in their work, have been there 25+ years, and actually care theat the custoemr is satisfied, the vehicle is fixed, and they have pride in their work...and guess what, I drive 20 miles out of my way to go there...might this be the exception to the rule? Sure.

What you say may be true at a large number of dealerships...but, perhaps, it could also be that there are those out there who really actaully want to do a good job, take pride in what they do, and may actually be fast at what they do and get paid 12 hours for working 6...anything is possible...sounds to me like at the dealership you mention...maybe they need a new service manager..or maybe they don't care and eventually will run out of customers. Or, maybe, it is just all about the money and they will survive...time will tell.

Won't call the dude a friend per se, our kids play on the same school sports team, so we just both have reason to be at the same places at the same time.

And for away games, well, he's belly'ed up to same hotel bar as I am in the evenings.

It has been my experience that service and pride in ones work, regardless of the industry, is pretty much no longer in existence (maybe it never has been, IDK). Not just car mechanics, buts roofer, carpenters, plumbers, tax preparers, medical doctors, you name it,,, good luck even getting a call back, much less actual quality work done.

Some call it a cultural shift or "new normal", but taking pride in ones work and doing a good job are now seen as what the suckers do because you can get paid the same (or more) for doing less.

Is he a mouthbreather too?

I used to be a dealer tech for almost a decade. Prior to that worked in an independent shop for even longer. My entire social circle and family were techs either running a shop, working in a shop, or in a dealer.

Your occasional drinking buddy either has the sweetest gig in all of automotive history or is embellishing for dramatic effect or the dealership has an exceptionally strange way of managing workflow.

Assuming the jobs are posted at random (they should have a dispatching system), there is no way he is not discriminating in some form or fashion.

For instance...

engine light on silverado truck. Diag time pays .5 hr. hook up scan tool see what it says. Fire it up in your bay to recreate the issue. Nothing found or can't replicate the issue?

See ya.

The tech isn't going to devote their life to it like it is a science experiment that will alter the course of humanity.

Are we seriously expecting a tech to spend a whole or half day for .5 hours of pay (some dealers pay 1 hour and fight with the OEM about it later on) diagnosing an issue that can't be easily replicated, or that "tech support" can't offer any guidance, or TSBs and SSMs aren't covering the issue.

If the tech closes it out at this point the job won't come back to him if the issue reoccurs. If he pursues it further to an actual scope of work, and it doesn't fix the problem, then he has to do it for free. There is a huge risk here.

Lets say the tech spends a bit more time (maybe an hour or hour and a half with the issue) in hopes of finding a probable cause that could turn out to be a decent job that he is confident in.

So in this example say it is an oxygen sensor is showing up dead as a doornail. Low risk. fairly easy job.

Put truck on lift. 5 minutes.
Order parts. 5 minutes.
Check over the O2 harness see if rodents got to it. Looks good. (15 minutes)
Take o2 sensor out using a special tool snap charges criminal amounts for. 30 minutes after you are done fighting with the connector.
Parts finally show up 20 minutes later.
You check to make sure it is right part. (5 minutes)
Replace o2 sensor and reconnect (10 minutes.)
Pull truck down off lift (5 minutes)
Fire up truck and check to see if the sensor is reading (5 minutes)
Pull truck up to front parking area (5 minutes)

So you have about 195 minutes devoted to something that will pay you a flagged hour of 30 minutes and about 25 for the O2 sensor job. So 55 minutes out of 195.

This isn't an issue with the tech it is the system they operate in.
