Hi All,

 

I can understand the concern and frustration that everybody is experiencing. As we do work on a case by case basis for vehicle concerns, I would recommend working with your dealer to attempt to get your concerns addressed. If you have attempted to work with the dealership, and are still experiencing an issue, we would be happy to look into your situation further. We document each concern, and report it to the appropriate parties in order for them to work on vehicle fixes, and continue to better our products. If anyone would like assistance setting up a case and working with a dealership or would just like their vehicle concern documented within our system, feel free to PM us your full name, contact information, VIN, current mileage, and involved dealership.

 

Sincerely,

We appreciate your reply BUT the dealers are waiting on GM to give THEM direction on this persistent problem....Can you not have the GM tech/engineers read this forum topic and surely they are smart enough to see they have a problem....Please do what you can to get the GM gurus involved and then they can inform the DEALERS about the possible fix! It seems that one arm of GM doesn't know what the other arm is doing and we keep running into a wall of "see your dealer, register a complaint, etc!" REMEMBER IT IS NOT THE LOYAL CUSTOMER'S RESPONSIBLITY TO FIGURE OUT A FIX - - IT IS GM'S RESPONSIBILITY TO ACT IN A PROFESSIONAL MANNER AND GET THIS RESOLVED AND SOON!!!!!!!!!!!!!!

I dropped $1800.00 on new rims and tire and tps sensors and new tires had a road force balance done. Truck acts the same as before. I started this topic and from what I've been reading I don't think my issue is as bad as some. My steering wheel is good unless I pull a light aluminum trailer. What I really notice is a feeling in the seat, left to right and somewhat of a bounce at times but mostly a gyrating feel in the seat base. The other day I was going down a hill that I go down at least once a day and I left of the gas and the truck bounced like I had flat spots on the tires. Funny thing is it wasn't like that before the hill or after. It almost seemed like it had to do with coasting under low rpm's. I really like to get this figured out because I'm afraid to sell my old tires and rims incase GM does decide to fix this and blames my issue on my aftermarket rims and tires. I was banking on it being tires and selling the old ones to help pay for the new, so now I still have an crappy riding truck and I'm broke!

 

I constantly analyze my truck while driving and since the tire and rims weren't the issue I think it's not just one thing but possibly a combination of many. GM said they made this frame stronger then the last right? They said it was lighter too. Then with mine I have the stiff Rancho shocks too. I think with the old trucks the frame might flex more and take up some of the road imperfections. Could this stiffer frame be like a tuning fork in a sense? Then why are they not all doing it, right? Well if you read the posts, people that notice it have test drove many (one guy drove 7 different trucks) and they all had a vibration including me (just tested one other). I think the people that feel it could get a someone else's truck that they feel is "smooth as glass" and feel the same thing that there own truck has.

Of coarse with any line of trucks there will be some vibrations from a tire or a wheel out of balance and new tires or a balance will fix. Not all the 14's that have a vibration are going to be the same issue but I think the majority are. Im not holding my breath that GM will fix this issue, after all they can't even seem to fix a loose seat cushion!

You bought even new wheels? Why? Rims are very easy to check for any problems when spun on a balancer. Assuming your tires are good quality and PROPERLY balanced, there must be some other root cause for the vibration issue. I mentioned before that some cheap rotors and brake drums are not even balanced and if they are not they could be a source of vibration too. Did you check your brake rotors for tell tale sign of metal being removed form the edge of rotor to balance it? And weights welded on the brake drums?

 

If it isn't brake rotors or drums, then I would start suspecting the vehicle frame for being the root cause. So they made it lighter? The only way you make a steel frame of certain dimensions lighter if you use the same steel is by making it thinner or removing extra bracing. Maybe GM is quiet because they already know that some trucks have frame issues?

Obviously after the 23th page the point is not getting across to gm. I understand his frustration. Gm support on here has been of no help and they are suppose to get the point to gm.

Update:

Just got my truck back from the dealer (second dealer, third trip) this is the dealer I purchased it from and that did the first road force and replaced one tire. After three days they said two more had excessive road force and replaced them (not sure how they passed the first time). Driving two hours home and the problem is worse than before. Feels like a wheel is going to come off ant 80, you can see and hear my stuff in the back seat shaking. While stuck in traffic for an hour I could even feel it at 5-10 miles an hour.

 

One funny note: Under cause of vibration they listed a faulty fuel pump and replaced it. Service guy never said a single word about that. Just mentioned the section about the two new tires.

 

He also said his shop foreman and service manager drove the truck and that it drove "normally". It would take someone passed out on drugs not to feel this truck vibrate and shudder. I'm sure GM is aware of this issue and working with the dealers to cover it up or prevent addressing the real problem. Probably due to $$$$

 

1500 miles on the truck and I absolutely don't want it. Miserable to drive and I'm tired of playing this game!

 

I am filing a complaint and contacting a lawyer, this is ridiculous. GM will make you take this all the way to the end with a lawyer before they even offer to replace or buy back the truck.

I just picked up my 2014 chevy siverado LTZ few days ago and noticed a vibration also at 70 mph and did a search on google and found this:(

I really like the truck

I called GM made a complaint and made my first appt already for this saturday for a wheel balance

 

It has 20s...continental tires..any help appreciated

I bet this topic scares a lot of people. I had a bad shake in the seat/floor the first time I took it up over 70mph. Took it back to the dealer right away and they took care of it, no issues since(wheel balance they said). I sure hope they find a solution soon for the ones having this issue, this kind of nagging issue makes it real hard to enjoy that new truck smell.

Just saw this.. GM this is just the beginning..Im glad we could save one.

 

 

Hey guys,

 

So after putting much thought into it, I decided to cancel my '14 Denali order.

 

I was really excited and eager to get it and it was due any day now, but looking at the recent threads and seeing how many people are having issues - everything from the sliding seats, warping dashes, vibrating hoods, uneven tailgates, vibrating back seats, etc...I just don't want to risk putting in $60k into this and then having to "live with the issues".

 

Now, I know some of you will say "you only see the negatives" and that may be true, but I don't feel right dropping that kinda coin and having to "live with it" or having a dealer try to fix something that shouldn't have to be fixed in the first place.

 

GMC's profit is about $12,000 per truck...they could have put a little more effort to ensure these things don't happen or hell...raise the price up and i'll gladly pay for it...I just don't want to live with the bullshit.

 

All in all, after much research...I'm most likely going to grab a '14 Ram Limited or wait a year and get a '15 Denali once they iron out the kinks.

This morning I even noticed it was shaking at at 45 mph and real bad at 70..*..This sux.truck is 2 days old and only 80 miles

A couple things: it isn't uncommon to have shaking on cold tires until they're warmed up, keep that in mind. Secondly, I noticed some vibrations SOMETIMES at certain speeds on my 2014, which now has nearly 6,000 miles. I have recently added new 20" rims and Michelin snow tires...I have not noticed any vibration since adding the new wheels and tires.

It is very possible the vibration people are experiencing is from the crappy tires & not the truck itself. Just throwing that out there.

Many have replaced their tires and rims and still experienced the issue. That said I don't know the quality of the rims and tires that were put the truck. In with you though I believe this is a tire issue....

The best way to eliminate wheels/tires as the root cause would be to have the dealer swap the wheels from another truck that does not have the vibration problem and test your truck with known good wheels.. This way you could at least eliminate one variable and start looking elsewhere.

Vibration prolblems are definitely among the most frustrating issues, especially when you cannot pinpoint the cause.

Ok..got to the dealer today for my vibration. .has 189 miles and continental tires.

The mechanic a friend of mine Thank god took very good care of my new ltz

He found tires off balance and 2 tires with bad road force so he ordered two new tires will be coming in soon

 

He drove it before anything performed couldn't believe how bad it shakes..badly between 60-70 mph..

 

Hopefully new tires fix it..

    • Hey guys, sorry for the confusison about this. This wasn't my experainnce, it was copied and pasted fom the net. 
    • The problem with failure rates or increase failures are there’s people who don’t have a problem. What are you doing wrong they say. We had 4 5.7 GM diesel’s in the family when they came out. One was flawless. My uncle who happened to be the most abusive. Early rotary engines were known to use oil. I abused my first car so bad in six months I replaced the clutch, transmission and rear end. It didn’t use oil. My brother in law has a 2013 Tahoe and an older Yukon. The Yukon has 280K miles. The Tahoe around 175K. He runs them to about 300K. If his lifters fail before that time he would consider it a failure. My Hondas, I know people hate it when I mention them. Identical engines. One with cylinder deactivation one doesn’t have it. One shudders when the eco light goes on or off. Cylinder deactivation. But wait! According to the web. It can happen with lock up too. So now people in the know are changing the oil and transmission fluid more often. Then you read it could be a programing issue. So what do you do? There’s lots of money involved. I see three ways to deal with it. One only works if you don’t drive lots of miles. Lease, never get out of warranty. Or only buy older vehicles with a good track record. They all have bad runs. Usually when there’s a change. Even Toyota and Honda. 
    • Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/        
    • UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update  
    • GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.
