I haven't posted on this for a while..My 14 sierra reg cab 4.3 2wd 61,000 miles 17" wheels. Still has the shakes, GM did give me a credit (1000.00) to purchase Michelins thru a dealer. what got me back on this is yesterday I worked on a friends truck..1994 chevy work truck  327,000 miles with original ball joints and my truck wasn't that nice riding when it had 17 miles on it, according to my dealer its the flatspots from sitting on the lot...(sat for about 2 weeks before I bought it). And my 02 Silverado that had 174,000 when I traded it in was like driving a Cadillac compared to this one. Oh well thanks for listening

to me vent..Its been awhile!

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Bought a '17 Sierra regular cab in December...came equipped with factory highway shake (bad).  

Was that "factory highway shake" standard equipment or an option?

Apparently it's a "surprise" option, installed randomly.  I wasn't even aware of the option before I bought the truck, figured it out on the long drive home.

Okay, so we're 797 pages into this thread and GM obviously isn't going to do anything to fix the problem... I have two vehicles, '17 Denali crew cab and a '16 Denali Yukon XL both with the shimmy/studder.  How many of you are planning to trade in for a '19 with the new design, or are you done with GM and going another brand?... and if so, what are you looking to move to?

looks like I'm part of this "club" too... I've got 1k miles on it and about 68-73 mph I get a little bit of a wobble. Steering wheel is a little off center so I'm hoping its just that

I wonder if this symptom is unique to short bed trucks.  My 2015  GMC  2500  4 x 4 with Duramax

Diesel long bed truck with 25k miles is smooth as glass. No vibes,  best truck I’ve ever owned and I’ve owned all three brands.

Same here. My '07 Sierra before buying my current '16 Chebby shaker was a great riding and driving truck, but turning into a rust bucket.  I feel violated #metoo LOL.  Not funny at all but wtf, GM isn't stepping up...

No way in hell I'll go for a '19.  That said, when the time comes to replace my '16 shaker I'll do in depth research before buying, which I did not do before buying my '16. 90% of the trucks I've had in the past 40 or so years have been GMs.  All but my current '16 were either trouble free or fixable.  Yeah I know, every brand has its issues and prolly every manufacturer might or will try and wiggle out of a warranty fix.  But GM has basically said flat out go fark yourself.

For those planning on purchasing a 2019 T1  GMC or Chevy,  Make sure you get it up to about 100 on the highway during the test drive.

Then maybe the decision of staying loyal or jumping ship to another brand will be easier to make. Although I hear this happens with Ford and Ram as well. Not sure about Toyota or Nissan.

I have a slight shimmy/shake only between about 70-80mph and I only see it when I look over at the passenger seat moving if empty. No steering wheel or console shaking.

Nothing like some report here or videos I have seen.

Never did I get above about 65 on my test drive.

On our '16 Yukon XL Denali (60k miles), we noticed the shimmy at 80 mph when cruising down the interstate.  Started first with checking the rims and sure enough, all 22" rims had some sort of out of round condition.  The dealer had a matching set of 22s in stock with factory wheels that we had to purchase for $3000 and that fixed it.  Then came the drivetrain shudder at 1200-1500 rpm when at speed (50-60mph and coasting in 8th gear with AFM engaged) and the engine AFM is switching from 4 cyliinder to 8.  Both my Yukon and Sierra have this studder, which feels exactly like a slipping torque converter.  I've taken my Sierra (17,000 miles) to the dealer 5 times since 14,000 miles now.  They replaced the engine mounts, fixed a broken valve spring (wtf), flushed the tranny, replaced the torque converter, and reprogrammed the ECM to learn mode.  Both vehicles have the 6.2L with the 8 speed tranny.  I've driven them in manual to override the AFM and it doesn't seem to help.  It seems there are multiple issues, both electronic and powertrain-wise going on and I'm not confident they'll get it fixed.  There's a lot of ideas within this thread in how to fix with aftermarket parts, but it seems there are varying differences in what exactly each vehicles studder/shimmy/shake is.  I've been a die hard GM owner due to their reliability and I just think the quest for getting too cute in winning the mileage game with competitors has made the future of GM trucks an unreliable risk I'm not sure I'm willing to take, especially at the price tags we're paying for these vehicles.  I wish I had just kept my '06 Duramax and drove it into the ground.

So is this bulliten NOT the fix? https://www.revbase.com/BBBMotor/TSb/DownloadPdf?id=198437

Would like to know before I schedule a service. 

 on my 2016 Silverado LT Crew
Thannks!

Didn't work for either of my vehicles. In fact, on my Sierra, they flushed the tranny and it was worse after I left the dealer even though they reported to me that it was fixed.

So is this a constant always at the same speed shake/vibration or does it come and go for people? 

mine doesn't start until it hits 70 mph, then until about 76 it starts to die down, but like someone else said, this shouldn't be happening to a 45k + vehicle, especially for how long they've known about it. I've got a 2018 with 1000 miles on it BTW

      Seems to be Missing a lot of Updates

      By newdude · Posted

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features. OnStar and Wi-Fi may not work after remote start CarPlay may not automatically reconnect Part of the Driver Attention messaging screen may be in English even though the language is set to something else XM may not work After a dead 12V the radio may set to Arabic at each startup Bluetooth contacts might not be able to sync with the vehicle During an OTA the 12V battery may drain Customer might see a screen telling them to return to the dealer After changing the Wi-Fi SSID or password a device may not disconnect If a device is connected on the 2.4Ghz band, nothing will connect to the 5Ghz one, which could show as slow Wi-Fi speeds Customers might have noticed Wi-Fi dropping in certain areas and reconnecting later Customer might see the top of the screen blinking during Android Auto Android Auto may not connect CarPlay audio might momentarily cut out The "Add Phone" button may be grayed out The radio may not start up   V167 Most Notable Improvements:   Outside Air Temperature is incorrect. -You may see a popup message for Engine Shift. (Corvette Only) After changing the exhaust sound they get a popup that "mode change not applied", even though it was. -When changing volume, the volume bar is for Traffic instead of Audio. -(Corvette Only) Improvements to the placement of buttons and text. -If the customer receives the message "Apple CarPlay Could not connect", the cursor might move in the opposite direction than expected when using the control knob. -Android Auto automatically starts playing their music, even though they have turned that off in settings. -Intermittently they have a red OnStar LED with no OnStar function and/or no audio. -The minimum length of the Wi-Fi password was increased to 12 characters. -The popup message "Driver Attention Check, check your mirrors or Super Cruise will shut down" may not have come up on the display when it should have. -Startup animation added for 20th anniversary of the V-Series on Cadillacs. -The Navigation app received location improvements when going under long underpasses. -In the Navigation app there are filters for charging points that the vehicle cannot use.   V164 Most Notable Improvements Most notable improvements contained in this release may include: Apps Intermittently, an “SD Card Removed” message will pop up in the Navigation app. While in the audio app, the radio may stop working. Trailer Tire Pressure sensors may not be learned in the Trailer app. Not being able to return to the home screen while in the Camera app. After an ignition cycle, the radio might go to a black screen or stop working if using Sirius XM. Spotify icon truncated on Audio app.   SXM When changing power modes with the ignition switch, the HVAC pop up might appear. During startup, the radio will show the brand splash screen then go blank. Receiving a confirmation pop-up when changing drive modes. A “Return to Dealer” message may appear on the radio screen. SuperCruise setting toggle may not work. System After an ignition cycle, the radio might go black or stop working if using Sirius XM (SXM). Settings When performing a factory reset, the radio may stop working. After performing a factory reset, the radio may stop working when trying to switch users. When trying to go into the Language section quickly after startup, the radio may stop working. Projection Wireless CarPlay cannot be connected after unpairing another wireless Android Auto device. When the Android Auto screen comes up to connect wirelessly, the screen may freeze if the Cancel button is pressed. Removed the Apple CarPlay Cannot Connect screen when a device fails to pair during the autoconnect process. CarPlay information may not show up in the audio app. Near Field Communications (NFC) chime may be heard when NFC does not work. The Cannot Connect screen does not pop up after the first connection on wireless CarPlay fails. Apple CarPlay is now functional in Guam. Over the Air (OTA) When a software update is cancelled, the downloading logo may still be displayed. Energy When using the Energy app, the radio may stop working. When plugging in the vehicle, the display might show “Now” instead of “Charging Upon Plug In.” Instrument Cluster Voice recognition can be started while on an OnStar or phone call. When downloading contacts, there is a progress bar and circles on the Recents page of the cluster. The temperature on the cluster and the display may be different. After receiving and ending a call on the secondary paired phone, the cluster may get stuck on the phone menu. Bluetooth Intermittent Bluetooth connection loss.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.

      What did you do to your "other" car (aka musclecar) today

      We try to make cruise the coast. It’s where our favorite casino is. I only want to spectate. Never took a car. Always had one to take. I belonged to a club once. Even when I used to drag raced. It was during test and tune. Probably because I’m not a night owl, party person.

      By Atlas · Posted

      Good looking Olds, and TRX!   I haven't been into car shows either. I'm probably not a convert but I did push myself this year to attend a few select events to challenge some assumptions and try to experience car-based social clubs in a different way. I joined up with the local Hagerty group for some cars/coffee events, group drives. A month ago I showed my '94 Camaro I rescued last fall at Radwood. Had a good time, but, there was some sitting around with the car and that's the part of shows I don't enjoy as much. I prefer to be a spectator, walk the show, grab a burger, go home.   Radwood was the only era-limited event, but where it had strict model year limitations, it made it up in variety. Having Jason Camissa there was also a hoot.   Where I see old 50's car shows, doo-wop and winga dinga music stuff fading out, same with "only" vintage muscle clubs, it seems to be the activity-based clubs/events which are gaining strong popularity. Places where all cars and interests come together.
