My 2014 Silverado is at 120,000 and running just as good as day one, not one issue with it. I know there’s problems out there, but complaining to others saying “should of bought a ford” doesn’t help

You'll be leaving blue oval quick enough.. they are not any better.

Just got this from a buddy at my local dealer. Looks like Chevy is aware and they are working on a fix. Sent from my iPhone using Tapatalk

Here is mine.  
 


Yep that’s it. I really don’t think it’s anything to do with the engine, It has to be that fuel pressure check valve or exhaust. This is on every motor across the half ton GM segment, I’ve heard the 6 cylinder do it and 5.3 and 6.2

Yep another good clip of it. I'll try to make a video of mine just to have. But yeah I agree. If one of you guys has good luck at your dealerships I will just call a different one than I went to yesterday and be more forceful in wanting the line replaced

So my truck still makes the noise. Fuel feed pipe didn’t work. It sounds like it’s literally right below my feet. Most annoying sound in the world. Bummer too because it’s such a nice looking truck.

Dropped mine off this morning and showed them the TSB.  Talked to a technician and he said they have dealt with the fuel line issue before, and exhaust leaks where the y-pipe joins the rest of the exhaust.  Service manager said they replaced a fuel line last week and so far haven't heard back from the folks so hopefully it was fixed.  I am slightly optimistic this will resolve my issue, and will report back when I get my truck.  As a back-up plan, there are good deals on Ram trucks right now!

I could have sworn I’ve seen a fuel check line exactly like the one in the TSB underneath the truck driver side right where the sound comes from, I bet that’s the source of the noise.

Please don’t forget to update us!! I’m going Wednesday and might not mention it if you didn’t get it resolved.

The line in question is between the high pressure pump and the feed line from the tank.  I took a stethoscope to the line in the engine and at the tank and there was a loud pulsation sound.  I could feel the line at the tank vibrating with my hand.  I am really hopefully this is the fix.  I really like my truck except for this sound.

I know that’s what is in the tsb but I’m saying I’ve seen a line like that underneath the truck also. I hope it is the fix but I’m not holding my breath either now since packerchev said it didn’t help his. Did you listen to this at idle? Cause mine is quiet until I’m in drive pressing the gas, it does it every once in a while on a cold start up though.

Did you check it with the light acceleration? because your video definitely represents the sound well, I just don't think you'd be getting it at idle

In the cab, I don't really hear  it at idle.  I can sometimes hear the buzzing part of it when I turn the truck on and it revs up.  I can hear it under light acceleration too.  Slow speeds, cruising speeds, it doesn't matter as long as throttle is being applied.  Much louder when towing my 5000lb boat. 

 

With the stethoscope, I could hear it at idle for sure.  I made my son rev the engine for me and the clicking got faster, and above about 2000rpm it was a buzzing.  The fits what I hear when the truck is being driven.  Its more of a chugging at lower RPMs and a buzzing at higher RPM.

Yeah, like I said your in cab video captures the sound well. I think I will try to poke around with my stethoscope and have someone find that low rpm spot where it really clicks. Maybe check under the truck where MOhunter mentioned there is a similar fuel line on the driver side

It really clicks at idle with the stethoscope, just can't hear it in the cab.  There are several of those black braided flex hoses in the fuel system.  Everywhere it make a bend they have one of them.  I don't suspect that any of the rest of them have faulty/clicky check valves in them.

      Transmission Woes :-(

      By newdude · Posted

      You need a better code reader/scanner.  You are missing codes.  Did the dealer give you a copy of the SAVI scan from that visit?     If the fluid hasn't been changed, change it.  Shudder will likely go away.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By newdude · Posted

      TLDR to my other post...   Hard. Pass.  Too many what ifs.     Are you set on a 3.0 Duramax?  Have you considered anything not GM just in case?  If you don't have to have a pickup, lots of other options for $27,000 out there.

      I see some red flags.   - No mention in the Carfax if the oil pump belt was changed.  LM2s had a 150,000mi service interval, and its got 164,245mi on it.  So right out the gate it needs about $3000-3500 for that to be done before driving it another 150,000mi.  Belt is at the rear of the engine.     - If something happens to the transmission valve body, the special coverage is expired by mileage.  That will likely be an out of pocket expense, with zero or near zero GM participation if something happened even though its in by time.   - 2020 LM2s seem to need timing chains after 80,000mi at some point.  They fixed this end of 2020/starting 2021 model year engines.  They will usually set a P0016 I think?  There is another $8000-10,000 if it needs a chain.  The main chain is at the back, secondary at the front so the pump belt would be done at the same time if it needed chains.     - Long oil change intervals.  7,000-8,000mi on average, probably close to 0% or perhaps to or beyond 0% on the OLM.  Lots of them not at the dealer which makes me wonder how much of the oil ran through that truck was the proper Dexos D rated 0w20 oil and not just gas engine 0w20, which is not the same at all.     - Long fuel filter changes, again likely taking the fuel filter life to 0% or more.  First one went 28,603, second was done 43,094 miles later at 71,697, from there another 46,452mi to 118,149mi, and then the most recent one 37,026mi later at 155,175mi.  So counting its original fuel filter, its had only 4 fuel filters on it.  No bueno IMO.         Good news?    - It has had only two warranty trips to the dealer.  The first free service (end of December 2020 on the Carfax), and the transmission reprogram recall (end of August 2025 on the Carfax).     - Truck did a LOT of moving, so that might explain the lack of emissions related repairs like bad NOX sensors, bad exhaust temp sensors, bad glow plugs, etc.         The "emissions system checked" could just be how something was flagged for Carfax.  GM dealers have to do SAVI reports for warranty repair orders so they scan the truck.  So its possible that is there for that?

      Thank you, @Z45!   NOTE - No all repair shop/Dealers reports to Carfax   That is my main concern.  The CARFAX looks way too clean for a 6 year old anything with 164,245 miles.  Even something known for reliability (like many Toyotas) typically has a lot more replaced, like a Nav screen, interior trim, shock/strut, or brake pads.  And surely the last set of tires (installed at ~58k miles) would be bald unless those were all highway miles.   I'm tempted to pay a local dealer to look up the VIN, but am not sure if that will be worthwhile.  Last time I did this, it was 100% useless, and I felt scammed - they noted the bumper was replaced years ago and that's it.  A 5-year old could spot the accident damage, even though nothing was on the CARFAX.   After giving the dealer a call, the truck may have a hard shift, but they have to verify with their mechanic if that's even a concern.  And I've test driven about a dozen of these now, many near Chicago, and half the trucks shift hard/odd at all throttle positions.  The ones with aftermarket lifts/larger tires shift terrible, and 3 stock trucks shifted so violently I thought the transmission valve body was going out.   At this point I'm conflicted, as I need a vehicle, and am coming up short locally.  Northern trucks in this price range tend to have either multiple owners, a lot of mods (lifts/oversized tires without re-gearing), and are generally in rougher shape.   If this truck showed up in your neighborhood for $27k and you had to purchase it sight-unseen, with the possibility of needing a 10L80 rebuild, torque converter, or rear end - would you do it?  I'm convinced most of the 10L80 trucks I test drove are broken, they can't all shift so bad, with massive flares/slipping/lurching and mis-matched downshifts like a teen driver learning stick.

      2027 GMC Sierra Spot Shots + Undisguised Interior (BIG Changes!)

      By Griffin Donovan · Posted

      From the spy shots, the front end does look like it's borrowing some styling cues from the Canyon. I'm more interested in the powertrain news than the screens though. If the 3.0 diesel survives into the next generation, that alone will keep a lot of current owners interested.
