Parked my truck last night :tear: I can't drive it anymore. It basically vibrates over 70 km/h and when the vibration makes you sick its unsafe. Dealer doesn't seem to care. $60K lawn ornament.

Sounds like you should start a BBB claim

Really? How many miles are on the truck? Have you taken it to another dealership? Have you contacted corporate customer service? What about taking it to a real mechanic? :nopity:

I wish I had the money for another vehicle so I could park mine........ I'm not that lucky

Well my 2014 was a 6.2 and it didn't start vibrating until around 1500 miles. It wasn't as bad as some of the others out there but still annoying enough for me to trade out of it.

Hey Bill, I thought you were done with this place :P

 

I had given up on the lawsuit and being here for a while, but have started doing both again.

 

I'm now working with a law firm out of Boston to get the suit going. I have sent them a substantial amount of information including TSB's for the regular Vibration, the Active Fuel Management Vibration, and the radio issues a few of you have (I have). I have sent information, pricing etc. about those of us who paid for upgraded A/T tires, but did not receive them, I sent the articles that were published about the SUV buffeting and vibration, which show that GM has finally admitted to the vibration in their SUV's. As well as some other information that I felt would help with the case. They have been sent my current list of members who have sent me their information wanting to be part of any suit that comes about, and they also have the video's I took doing the water bottle test in my truck. I feel that those are pretty damning, but thats just me.

 

Hopefully this gets off the ground quickly and can benefit us sooner rather than later.

10000 kms, Working 14hr days to pay for truck and no time to screw around with other dealers unfortunately.

I don't have the money.. second vehicle is worth $300.

 

Update:

Dealer has picked up the truck and finally working on it. Lets see where this goes. Hopefully a real mechanic is working on it.

I can't help it, i'm addicted. I keep coming back in hopes tat there is a fix. You'd think i wouldn't care one way or the other as I drive a Tundra now but I"m still rooting for you all. I keep coming back hoping I will see IT'S FIXED !!!!

It would be nice if there was a way to put vibration sensors in multiple locations around the truck, tied into a diagnostic computer, and run down an ultra flat stretch of road and pick up the sensor with the most vibration and concentrate on that area for issues. Anybody tried replicating it on a dyno where only the powertrain and rear tires are the items that could be the cause? It Would eliminate both road surface, front end components from being the culprits. Or i guess it would eliminate the powertrain and rear suspension depending on the results. just a thought. I do notice my hood buffets at high speed but, i can't see it being that.

This is truly the step that needs to be taken, apparently GM or the dealer does not want to invest in the time required to do this. It would help locate the are causing the issues. You could do it with a single sensor and just move it from location to location. The problem for the average guy is a vibration analyzer with say 4 inputs the acclerometers and cabling is going to run about 10 grand on up. I used to work as a plant engineer and we had a unit made by SKF for balancing high speed turbo machinery (turbines, compressors, fans and such) it had 4 inputs and cost 30 grand although it had other features for balancing and shaft alignment. I've been looking into it and for the DIY guy your best bet is to find an old EVA2 unit, this is what GM used to use before the PICO scope. You can pick one up on ebay for about $400 bucks single input I believe but you could move it from corner to corner and different frame locations to help narrow down the source. As far as the wheel dyno goes, dyno time tends to be spendy and not readily accessible but would eliminate the road surface as a source. Right now as I type this my truck is down at a local tire shop and the tires are being trued and balanced on the vehicle if it still shakes after this I'm going to say it's almost impossible they are the source, and it might be time to purchase an EVA2 to find the source because the dealer surely isn't going to log in the time to do it.

I guess a place that offers vibe analysis would be spendy too. I am sure a dyno owner or the friend of a dyno owner may be able to give this a shot for not much investment. but like you say a $400 EVA2 would do the trick, perhaps. A dyno would be way sweeter though as you could eliminate so many variables and concentrate on a certain part of the truck instead of happlessly trying anything

Most people have trouble determining if the vibration in their vehicle is coming from the DRIVESHAFT or not. There are typically two types of vibration most vehicles would have. A fast cycle vibration or a slow cycle vibration, to help understand this lets say we put a bucket of water on the passenger’s floor. If the vibration in the vehicle produces small ripples on the top of the water this would be considered a fast cycle vibration. This type of vibration is usually a drive train vibration, things like the driveshaft, motor or torque converter. If the vibration puts waves on the top of the water or splashes, this type of vibration is a slow cycle vibration and usually is an axle or tire vibration. People have trouble determining where the vibration in their vehicle is coming from. Try the test below if your not sure.

Why, straight into the "NORMAL!" land. The truck vibrates as designed.

buy a tire crayon and mark the rim to tire in two locations on each wheel. Maybe these tires are spinning on the rims now and then? Friend mentioned to me that on his 6.2 Denali CC 2015 that the bar codes were working their way out of the wheel lip and sticking out. he couldn't understand how that's even possible. never ONCE thought the tire/rim were not bonded well enough to avoid slippage.. We're not talking about 10 second race cars lol.. I'm going to do it to mine.. My front right tire was badly out of balance (according to the dealer requiring a flip 180* out on the wheel) and all others were slightly out. imagine that this was causing more problems after or even before the original Root of the vibration (driveshaft, rear, shocks etc) have been repaired??

 

fix one problem, another rears it's head sounds alot like tire slipping on wheel.... i hope you guys try it and report back. make sure to get on the truck especially from a stop and low speeds, that should expedite the results as that's probably when the tire would slip most.

Everyone please read these articles and email the editors so we can get some attention on our trucks. There is a gentleman named Daryl on the Facebook group that got the ball rolling. It's up to us to get attention on the trucks as well. Again please I'm begging everyone to do this. The SUV already has national attention!!!!!

 

I've even attached each editors email address (couldn't find the one for autoblog still working on it and will update when I get it).

Thank you for the links to the articles. I have updated my website. If it makes anyone else feel better, my website has had a couple of thousand views and almost two dozen people have confirmed not purchasing a GM because of what they have found on the website and the forums listed within it.

 

GM Customer Service called me this week to see how I was enjoying my replacement 2016 Silverado. I directed them to my website :)

    • If everything checks out at the MAF, then the MAF is BAD, new or not.   You don't need a signal generator to troubleshoot this. PCM needs ALL powers and ALL grounds able to light a halogen headlight bulb - if it can light the bulb bright, then the wiring is good enough to run the PCM.   Best thing you can do for yourself is spend some time here: scannerdanner.com - Check out all his YouTube videos on similar issues. If you decide to subscribe it's the best bang-for-buck ratio in the automotive world, hands-down. He's got TONS of free vids on YouTube, too.
    • Yes, I used my multimeter to probe all of the wires at the MAF, both with the sensor connected, sensor disconnected, key on engine off, key on engine running, etc etc etc. I probed all of the wires again at the PCM, at the connectors, etc. All voltages are what they should be according to the service manual/wiring diagrams. All grounds are good, less than 20 millivolts from the battery negative under load. Both at the connector of the MAF, at the PCM connector etc.      I know this throws a pretty big wrench into things, but this truck was acting up before the swap. I don't have very much information, if any on what was causing it, but if you cleared all of the dtcs it would do the same thing where it would crank, fire, then die. And it would do the same thing a dozen or so times, and eventually it would start and run, but the difference is that it would run and actually be drivable. Whereas now if you can drive it at all, it goes into reduced power mode almost immediately, and even then it's not running correctly. When you come to a stop at a light it stumbles down to for 500 RPM before catching itself and returning to the smooth idle. And if you go more than about 50% throttle then it immediately goes back to doing the misfire thing.    Like I said, I know that throws a wrench into things, and unfortunately I was not able to pull any data or anything like that before I did this work, so I don't have much to go on.    I'm trying to not fixate on one particular thing as the cause of the problem, but it seems like all avenues are pointing me towards the PCM. Like I said I have tested the wiring extensively (see above), and during cranking the sensor does produce seemingly legitimate values at least according to my multimeter, but as soon as the engine fires those values quickly descend into gibberish. I've tried it with multiple different known working sensors, I have done literally every test I can think of multiple times on the wiring (probing the signals, probing the pins with the sensors unplugged, probing the pins at the PCM, voltage drop, voltage drop under load, continuity, ohms, and double-checking everything against the wiring diagrams/ proper values in the service data.)    Another thing that pushes me towards a possible PCM failure is, I have noticed in troubleshooting a little bit taking a break and coming back, that when I leave the truck to sit for a while and cool off, it starts and runs smoothly when I first start it up. However once it warms up. It starts having problems. For example, when I went out to the truck this morning after it had been sitting overnight, I was actually able to drive it down the block. And then once I got on the throttle a Little bit after going about a thousand ft, it started misfiring again. I pulled it back into the driveway, shut it down, and started it back up. It idled smoothly. As soon as I touched the throttle it did the misfire thing again. From then on as soon as I started it it would misfire. I shut the truck off and went to go get a coffee and do a bit more research. When I came back out I started the truck up and it immediately went into the smooth idle. After a couple of minutes of playing around with it, it would not idle smoothly anymore. Let it sit a couple of hours, rinse and repeat. This makes me think with temperature change something is going wrong inside the PCM. I have the PCM out of the 2007 donor vehicle and I'm thinking of getting a one-day subscription to the ACDelco programming service to try and program that and see if it helps.   Like I said, I'm really trying to not fixate myself on one potential cause, but it seems everything is pointing me towards PCM failure. I would really like to try to confirm that, but unfortunately I don't have an oscilloscope or a signal generator to do the GM service procedure where you feed 5 khz into the signal pin. 
    • Ahh, sorry about that - I got some bad info. Newdude is correct. That's what I get for working 13 hours straight ... on my "vacation", lol.   Should've checked the files I had instead of the internet.   Anyway ... this is GREAT news, since this would've been an absolute friggin nightmare to get working.   I don't think the lack of VVT is causing this - you've got another issue. Wiring, I'm betting.   I'm telling you right now, your computer isn't bad. If it worked before the swap, it's working now. You need to do some more (better) diagnostics and figure out exactly what you're missing. Did you test every wire directly at the MAF? Have 5V reference? Ground? If you're reading ZERO g/s, your Hz isn't much use - it's going to be the wrong value anyway. The MAF is not working, and you need to find out WHY.   I got this off the net, so VERIFY first: Pin A: Black (BLK) wire, Circuit 552, serves as the Sensor Return (Ground).  Pin B: Tan (TAN) wire, Circuit 472, carries the Intake Air Temperature (IAT) signal.  Pin C: Yellow (YEL) wire, Circuit 492, is the primary MAF Sensor Signal output to the PCM. Pin D: Pink (PNK) wire, Circuit 339 or 539, provides Ignition 1 Voltage (Power).  Pin E: Tan/Black wire, Circuit 552 or similar, often associated with the Intake Air Temperature ground or signal return.  Global-A list: https://postimg.cc/KKJnQC85    
    • Correct....the end user can't reach to Realtruck directly like they can if they purchase a Bak, Undercover, etc...  It has to go through a dealer.
