It is most likely the adaptive valve. Some owners have had their OEM exhaust system replced due to this issue. Others have used a hose clamp to force it open to prove it is the culprit. I have also read there is a newer version OEM exhaust that replaces earlier built units, but haven't seen a bulletin on it.

 

Of course they had dealers that were willing to keep pushing for a fix. Good luck.

Someone was whining about the cupholder being too small. :freak:

 

Anyway, you can pull the rubber insert out and it's bigger by a good amount, if you just have to have 32oz's of pure cane sugar. :fart:

 

Maybe we should bitch that there's no microwave available in the center console.

Ohh man, I been looking front to back, top to bottom for that microwave and coffee maker.

Dealer told me I had to find them, that's why I bought the thing. Should I return it?

My 2014 Silverado now has 3800 miles. From day one the truck squeaks or chirps each time it changes from 4 to 8 cylinders. Wrote Jennifer as requested. Ended up with Jacqueline. She left me a voice mail basically saying the dealer could repeat the issue, but they have no fix. I've called her back twice, and she does not return my calls. The frustrating part is that GM does not know how to fix their factory defect nor do they show much interest in figuring out how to solve the problem. Any recommendations on next steps?

it is the adaptive valve in your exhaust system - they now know what causes that issue.

I just clamped mine open today and the truck doesn't sound like it has a turbo or chirps between v4-v8 modes anymore.

Mine doesn't chirp, but wondering what way you rotate it and how you know its open all the way? Wondering if opening it would help out on the black smoke at start up at all.

Adaptive valve has nothing to do with the black puff of smoke on startup. It does have to do with the direct injection on the new trucks.

Rotate it counter clockwise

I have contacted GM and have a case number. GM has contacted the dealer and things are in the works. This has soured the new truck experience.

I was reading today's issue of USA Today and came across the latest round of RECALLS from GM: 477 full-size trucks from the 2014 and 2015 model years for a tie-rod defect that can lead to a crash.

GM's district manager told the dealership to go ahead and fix the 25+items on the defect list. Fixing these items will mean taking the truck to a body shop and ripping apart the interior. Im pissed. Carfax claims to have 5 reports on this new vehicle. Wondering if I should spend the $40 to find out what it consists of?

I would have to say that I would not be able to sleep well unless I knew what was in those CarFax reports. It may be recall info that does not show up being checked br a GM dealer or something else.

There may also be some info that may help you in the endevor to have the truck repaired...

As unhappy as you are I would, if it were me, spend the money on the CarFax. Best of luck in you in your quest to correct the defcts.

Thanks. I'll probably get the report and post what it says.I'm surprised Jennifer is not trying to help.

X2 on getting you're own copy. No chance Carfax has recall info that Dealers do not.

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
