I believe it’s all to much with the engine switching cylinders on and off the transmission with 10 speeds and auto stop I can’t tell it’s a V8, unless you run off auto stop, shift using manual paddles and gas it!

I believe it’s a software and hardware issue!

Dump the Junk let Bitchin fix it!

For $76k I want my money back GM and Chevrolet so I can buy a truck that works!

it’s not enough that I spent my lifetime buying and collecting corvettes and other vehicles from GM only to buy my last vehicle and get banged on my Final Truck Purchase!!

there a GM service bulletin covering this issue they are aware! It involves Trucks built with the 5.3/6.2 engines with 10 speed automatic transmissions!

it time for the huge Lemon in the bed and park it across the street from my dealer!

oh I’m a disabled combat veteran!

I have had this exact same issue with my 2023 Chevrolet 1500 5.3 10 speed. It is absolutely awful to drive and is so annoying. I can’t believe they are letting these off the lot like this. I’ve had the fluid changed/pan dropped/torque converter changed/valve body changed. Nothing has helped. After the valve body change didn’t help the dealer just said well I guess it’s just going to be how it is. I cannot accept that. I paid for a brand new truck, there should not be issues like this. It is not right. What else can someone do besides seek legal advice?

I am having the exact same issue as others here with low speed vibration/shudder around 1200-1500 rpm.  I also took it back to the dealer, twice in the first 10000km and, just like the others, the tech said they could not replicate the problem.  Also like the others, it’s a 2023 Sierra Elevation 5.3. I also described the issue to the tech as similar to driving a standard transmission and shifting too early, resulting in a shudder.  Considering the number of people with the exact same problem getting the exact same response, I am in agreement that they are fully aware of this issue and just not addressing it.  

Otherwise, the truck is amazing on the highway, has no issues under higher speeds, even at the same rpm, but this low speed shudder is driving me nuts to the point where I’m wondering what kind of loss I would take selling a less-than-year old truck with 11000km on it.  

*unsatisfactory update from the tech at my dealership:   He says this is the DFM cylinders deactivating and the transmission is responding. The combination results in the vibration/shudder.   
Considering how many people are annoyed & dissatisfied by this, you would think GM would have a fix by now.  Nothing they can do in the meantime while we all wait for GM to come good on this.

I was totally against cylinder deactivating. I’ve since experienced it done right. I’ve seen it engage for extended periods of time. Unlike my experience with my GM truck. So can it be done right? Yes. Can it be done without affecting longevity? Yes.

Need an American sourced Torque Converter instead of those little donuts made in Mexico! They are total junk!

I traded my 1900 miles 23 Silverado HC 4x4 in on a 24 Tahoe HC 4x4 with a 6.2 and Wow nice smooth ride!

2024 GMC Sierra 1500 5.3 w 10 speed here and I’ve had vibrations and shudders at 40 mph and 65 mph since I bought it. Can’t be normal right? I’ve had my tires replaced by the dealer - thought it was a wheel balance issue, but the shuddering persists….

So I have a 2023 gmc Sierra 1500 elevation model with the 5.3l and 10 speed, when I just maintain speed around 40-47 miles and hour it rumbles and slightly vibrates, almost like running over little bumps. And happens in lower speeds as well. I’ve drove in L9 in which the problem leaves, so I know it has something to do with DFM. But I’ve seen other post talking about it being DFM, that was fixed with the transmission valve body being replaced. And was wondering if it was a common fix for this issue and if it’s worth bringing to the dealers attention, thanks.

My '23 sierra x31 (40,000 km) is starting to display these shuddering symptoms. Seems to be when I'm driving at a constant speed under 60km/hr (1000-1500 RPM) or around 100km/hr.  It will stop shuddering if I quickly shift to neutral. Definitely rules out alignment or tire issues.

GM mechanic rode along with me and could feel it also. Said he thinks it's likely the torque converter.  Appointment next week to have it replaced. We'll see what happens...

Mine started on day one! 4 dealerships said it’s ok it drives like another one that the Chevy Rep drives; it’s normal they all said!

 

Thank you Chevrolet for this P.O.S. 2023 Chevrolet 1500 Silverado 4x4 5.3l High Country! Lost $10k.

My 2020 GMC ZRX does the same thing and sometimes it doesn’t wanna shift gears, up or down. Said they couldn’t make the truck do it again and it was shifting fine. Well it’s not by any means. Mostly 4th to 5th or 5th to 6th. I’ve heard it’s the DFM but also heard of similar problems being corrected by replacing the valve body in the transmission. I hope I don’t have to buy another transmission like I have my past 2 trucks. Did they ever resolve the issues with your truck?? Or any of y’all’s trucks?? If so, what did they do?

I have the same issue. I have 2022 suburban vibration starts when the truck was 25000 miles. It is vibrating when you maintain the speed it it very annoying. I took it multiple dealers and done some work but still the same. New tires, Transmission body valve, torque converter, fuel injections, fuel pump, drive shaft all replaced but vibration still there. Even dealer is tires of it. I am giving up please if someone know how to fix it share it.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
