I have a 2015 Chevy silverado LTZ 40k truck and I have the same problem. The squeeking churping sound is annoying. I have an appointment with the dealer Wednesday but it sounds like this may be a waste of time. My friends told me not to buy a Chevy I should have listened. Trading truck in for a Toyota. I swear I will discourage people to buy chevy!!

I have contacted corporate about this. It is getting on my last nerve. I hate driving around the city or even on the highway and when I go to hit the gas it sounds like a piece of garbage car squeakin

With all due respect Patsy G, the dealers aren't helpful at all. I've already refunded my extended warranty because they won't fix anything on my truck unless it's on fire and shooting fireworks into

I just noticed one difference between my dads truck and mine. I have the 3.08 rear axle and he has the 3.42. Could that make any sort of huge difference?

Well add me to the list. My 2015 5.3L with 13,000 miles just started doing this. I'll be trying the "clamp it open" fix to test what it does. After I get results I'll set up an appointment with my dealer.

GM replaced my exhaust system from the catalytic converter back today. It's nice and quiet now. I hope it lasts. It sure was nice driving home without the flapper noise.

It'll last about a month. (personal experience)

Brian,

 

Did Sutliff do that work? I am near Gettysburg but have not been happy with most of the dealers around here (not just for this problem or vehicle -- they have been terrible on my last 3 or 4 vehicles). It's about a 45 minute drive for me to Sutliff but it may be worth it.

Looking at how the flapper is designed I don't see where just replacing it would make it quieter. It's a valve and a spring. Not much to it. Unless the replacement is an improved design of some sort.

Yep Sutliff. They gave me a brand new Malibu LT with the 1.5L Turbo to drive for the day, what a fun car to drive!

I have this squeak on a brand new 2016. Picked it up two weeks ago. Didn't start doing it till it hit about 800 miles.

Had my muffler replaced under warranty today.

 

All it cost me was a nice door ding that I picked up while it was with them.

I have a 2016 GMC Sierra and this squeak that it makes is seriously annoying. I bought this truck brand new about 4 months ago, this is rediculous. Dealer said they've never heard of this, not getting much help. If I wanted a squeaky Truck I would have kept my old one. I want it fixed ASAP or refund my money.

Well I watched the readout on the DIC and confirmed that it happened every time the truck went from V4 to V8 mode. I climbed under the truck and bolted the Passive Exhaust Valve open like the previous post said and the sound stopped. Drove it all day today and didn't hear the chirp once!

 

It's going to the dealer this Friday for an oil change and inspection so I'll be showing them the PI for the problem.

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter

      My First Project and GMC has me stumped

      By asilverblazer · Posted

      I had an alternator fail that was shorted internally in such a direct fashion in addition to the larger gauge cables that it appeared like a VERY dead battery. Granted I think the car did power up, it definitely wouldn't start.   Rodent damage to wiring?

      Towing In Loose Gravel

      Using experience to justify bad advice is lazy and typical of someone incapable of articulating why their advice is prudent.    This immediately sets off the BS alert and the advice that followed certainly qualified.   Asking an idiot for help getting out of dumb situations because he is an expert... at getting himself into dumb situations.   Unless I've been living in an alternate universe - the first thing everyone does when getting into a sticky situation is shift to a higher gear 🤨.   Of course not, the torque multiplication, mechanical advantage and finer control typically afforded by the lower gear is far better suited for this scenario.   There ARE scenarios where a higher gear MIGHT be appropriate determined more by the drivers ability to control EXCESSIVE wheel spin versus applying torque to the ground.

      I'm not sure I agree with "extreme" low speed, high torque sentiment here with regards to the prescribed use of low range. How about...whenever it's needed?   A 2.72:1 transfer case and whatever differential gears these Silverados have (3.42's, maybe?) aren't producing "extremely" low crawl speeds. Or insanely high torque multiplication. Even with the 1st gear in these newer transmissions. But it does provide mechanical advantage and potentially better control at slower speeds. And with extra weight or towing, I think it adds mechanical sympathy for the truck as well.   Plus, traction control and the other assists generally turn off when you shift into low range. Those aren't needed here, they'll work against you if you need wheel spin. In high range you'll need to figure out how to turn off the various modes those assists provide. Depending on the vehicle, those things don't all automatically turn off or turn completely off.   While I agree that a farmer might have some great practical experience, a recommendation to "always" using one gear isn't very informed advice. If the farmer had said WHY and could explain the physics behind his prescriptive "always" I'd definitely listen. The way he's described here makes it sounds like he could either be uninformed or is telling everyone what worked for him, not necessarily that there could be a more advantageous way about things.
