I am taking my LML into the dealer next week to get the smoke issue (when the truck goes into regen) addressed... I had heard that the repair is to replace the gasket and re-seat the downpipe behind the turbo on the exhaust... I was hoping someone would give me a good technical description of what it is that I want to the dealer to do incase they haven't seen this issue before..

 

The other thing is that I had heard there is a new Flash software update that addresses the issues with the Urea tank, where people's trucks are going into limp mode with a tank that's not empty.. anyone know anything about this? what's the best way to ask my tech to make sure I'm fully up to date?

 

thanks

you want to tell a tech how to do his job as a veh owner?good luck if ya get to the back lol

 

they have seen your concern lots,they have a techline to get help from,they dont need you telling them anything.

 

your confidence in your dealer is shitty at best or you are very anal and hence a big pain in the ass ..

 

the powertrain is under warranty for 5 years..relax

 

you will get nowhere thinking the way you are ..

 

if you were in my bay and started telling me ,you would be asked to go see the service manager before you finished thinking about what you wanted to say ,,

 

or if ya got to the back i would go get the service manager and he would politly remove you from the shop..

 

rant over

 

ps

 

has this worked for you before ??

Govtech.. wow.. you remind me of some of the mechanics I deal with in my line of work... "How dare a pilot tell me what' broken??"

 

Anyway..I called the dealer, and AT LEAST the service adviser seemed to have no idea what I was talking about, so I was hoping someone here could tell me what the two service bulletins were..

 

Do you seriously think that just because I have a warranty, that I am ok with being stranded someplace, or that I"m ok with smoke rising from my hood on a $60,000 truck? No, I want that stuff fixed NOW.. thanks for the help anyway..

 

 

PS.. And yes, that has worked before. I always do my homework before I go into a dealer (whom I NEVER have full confidence in)

 

 

700Sprotsman, will do...

sam,service advisors do not know anything,they write work orders and provide you with an estimate for repairs when not under warranty,, for warranty ,they again write it up using the correct codes ,the tech takes care of the rest,the advisor closes the work order,

 

towing is free

 

i wish you knew how the garage works and the system that is in place to get veh's fixed.

 

good luck sam,it should be fine

hey govtech4, stop now.

The individual wanted to know what was going to be done so that he could check that the work that was done was first done and then correctly. They also probably want to know what parts of the truck are going to be touched to know if something goes wrong after the work if the work done was at fault.

 

By the way, I was a body tech that got out of the business because of guys like you. Even when working with mechanic shops with my own vehicles, I want to know what was done and what caused the problem. Now, having a customer stand behind me while I work is not great, I have had it done and if it makes the customer more confident in the repair then so be it.

Now, if you never ever have made a mistake and can run a business from the front office by telling every customer "the repair is done, now take it" great for you. But I would first leave before you could lay hands on my car and would never let you even align a go-kart.

 

Good day sir.

 

I would like to hear about the turbo down pipe issue myself. I may be interested in a diesel in the future and I have only owned 3 vehicles that have been under warranty. And when techs fail to find codes, I usually go back to good old methods of tracing the problem.

cwendel, thanks for understanding me... I mean to be honest, I don't distrust mechanics as a profession, not at all... but people as individuals are an unknown quantity until you get to know them well... I have a mere 1600 miles on this truck and I have never worked with this dealer on anything .. the only experience I have with them is that (at least at the service advisor level), they know nothing about both of my issues....

 

I was hoping to find a knowledgeable mechanic on here that has worked both issues so I can go into the dealer with my "homework" done...

 

No offense was meant, and I hope none taken... Gosh, I always thought you Canadians were more laid back..

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      AFM Disabler Question

      By Grumpy Bear · Posted

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, the key seems to be with the half tons that if it has the Z71, then it definitely has the two speed. What got me was that the two speed AND the lower geared towing package option could not be chosen together the last few years unless it was mated up to the 6.2. Want the 3.0 duramax and 3.73 tow gears ... nope, can't get the two speed transfer case ( neighbor son realized that after he had bought his used 3.0 half ton .. where the frick is the low range ? ! ).    I am still unsure which truck series, the half ton or the HD truck that the original poster is referring to for sure other than yes his question is in the HD section of this forum but that doesn't guarantee the question got asked in the right section.
