Shake or Vibration Issues

[Jesse Davidson]

It boggles my f*cking mind as to why people say "I've been lurking/ following this thread for a while and I just bought XXX and I have the vibe issue" If you've been following this thread, why the f*ck are you buying one of these pieces of sh*t? You have clearly seen the issues we are all having, what makes you think you're going to be so f*cking lucky that you won't?

 

On another note, I'm astounded that GM has come back to this thread, knowing how this has been going, I would think they would want to completely avoid this and pretend like they are capable of doing something for us, not that these reps have any authority to do sh*t, which is another issue I have with GM at the moment. Although, I am glad they made that post, because I have taken a screen shot of it and now sent it to my lawyer with the part about we shouldn't have to deal with issues on a '15 truck highlighted. So thanks for returning GM, I appreciate it, not that you will do anything to fix our trucks.

 

sorry for the rant, I just read the last 3 pages and got really pissed off with it

First year depreciation can be up to 25%, in some cases more, but average is around 20% of the purchase value on new vehicles. This applies to all vehicles. The more the vehicle costs, the larger the percentage depreciation dollar amount is. A 46K truck at 20% 1st year depreciation is now worth 36,000.00 on average. These numbers have little or nothing to do with the vibration issue some trucks are having here.

so you would agree that Ram and Ford dealers offering me 32-35k for my 62k truck with 700 miles at the time is absurd.... by the way, they specifically said its because of the issues GM is having. So GM not having their sh*t together is literally costing people money

 

By the way, Happy New Year Everyone... stay safe, and try not to vibrate off the road tonight

Yep, absurd.

 

Expect a dealer to attempt to capitalize on anything they can and give you any excuse to low ball every trade. That's just what they do, vibration or not. They'll give you any excuse they can along with their ridiculous trade in price in an attempt to justify it. Had you traded, they would've turned around and attempted to sell your truck in the 50's.

 

The typical Chevy dealer would've offered the same or near the same trade in value for either of those two brands under similar circumstances.

Did the same thing, lowered the pressure on my 10 ply tires from 42 to 32 and significantly lowered the vibrations as well. Problem is the truck now handles like garbage leans in the turns and just has a squishy feel to it.

 

 

Anyone else that has had the vibes for a while check the lower portion where the struts welds to the mounting eye that connects to the lower control arm. Mine are starting to crack. They are not the original Rancho's that came on the truck but 6 month old Rancho RS9000's, I contacted Rancho to see if they will warrant them. Just curious if anyone else with the vibes is seeing cracks in this location on the factory struts. Part of it is poor weld quality where there was a void left from the weld process that has helped facilitate the crack propagation. Rancho's "lifetime warranty" doesn't include their quicklift struts they are covered by a laughable 90 day limited for work and material defects. But I'm giving them a chance to stand behind their product. These things only have 8000 miles on them. We shall see how they handle it.

 

 

 

sorry, been in bed sick since sunday and havn't had a chance to look at them yet

I calculated that I should have been offered roughly 45-46k at a minimum, and I would have accepted that just to get out of this thing. I came to that by taking the MSRP, deducting the incentives, then deducting a full year of depreciation even though the truck was less than a month old with about 700 miles on it..... there was no chance in h*ll I would ever accept 32-35k for it. Now I'm suing GM instead of dealing with this bullsh*t, I have the 3 required repair attempts I need, I have documentation of fraud, I have documentation of deceptive practices, among other things. I am NOT letting them screw me on this.

Just saw this posted frame and body mounts to stiff on GM SUVs. As alot of us have thought this is the trucks problem.

First of all I hope you didn't pay MSRP for your truck because it truly is not a $62k dollar truck, just stickered as one. A large majority of people on here including myself got their truck for 25% off sticker. That is good for the buyer but not for those who are looking to trade or sell. The truck is also depreciating at 20% or so the first year and continues to do so. That would make your truck worth about $38k as a trade in and low $40's for selling out right. That's life when you buy a new machine made with the lowest contract priced parts (any company does this).

We need 40 vib trucks to give to the engineers that are working on the vib solution and make them drive them every day until a fix is found! I say they would be less donuts and coffee.Sorry for double post. Edited January 1, 2016 by WLC

Apparently many still believe that only a few people have this vibration problem with their vehicles and that vast majority of these trucks are trouble free.

does your tr

Does your truck have plow prep package? If yes, heavy duty cooling including transmission oil cooler, and heavy duty alternator should be a part of that package. If it overheats, I would try lower temperature thermostat, e.g. 180 degrees.

I spoke with the engineer on this and this would not do any good. The problem is when the truck reaches 40mph it creates a vacuum and sucks the air from the engine compartment out through the radiator(GM put the truck in the wind tunnel and found this out after the truck was built). I came out of a 2013 with the same options and the plow was transferred to the 2015. Never had a overheating problem with the 2013. The difference I see between the 13 and the 15 is the 15 eliminated the holes in the front bumper.

Another approach you could try is more powerful radiator cooling fans, perhaps with a manual control switch. Can you modify the existing bumper and cut some holes out in it, or get an after market bumper with proper cutout for air flow? Is the truck truly overheating, i.e. the computer goes into the limp mode, or does it just register higher on the temp gauge? (Apparently, eliminating those holes in the bumper saved GM $ 1 per truck)

after driving 4 of these, in these, with trailers, full loads, highway, smooth rough etc etc: a, 14 CC/AT 5.3 (6 speed) 4x4, 15 Denali 6.5ft bed 6.2 4X4, 15 CC Silverado LTZ short bed 6.2 4X4 Max trailer, 16 Dbl Cab/AT 5.3 (8spd), I am convinced GM is perplexed because the (full size pickup trucks) frames/body mounts/design, are built upon a poorly engineered (for the EXPECTED ride comfort/quality of today's standards) configuration.

 

Maybe it's as tough as nails (we all remember the frame twisting of the F150 so bad that the pickup bed wouldn't open vs the chevy that didn't budge on that offset suspension compression demonstration) but for ride quality (which is SUBJECTIVE, but majority posting here it feels like it's OBJECTIVE, i understand I am one of you lol) it's terrible...

 

We have become so accustomed to a smooth riding pickup that in OUR heads this truck should haul, handle and float down the road like a Dump truck, Corvette and Cadillac Coupe De Ville...... I get it. I leased my truck, i love my truck, but I would NEVER buy this truck because even though the vibration can be "masked" with a variety of solutions like tire brand/model change, Shock valving it isn't changing the end result.. something in this design is not bringing the truck TOGETHER.... it's trying to do all and failing MISERABLY at only one... The "Cadillac" part... it handles great, hauls great and rides like crap...

 

My friend's Denali has Mag ride, the Silvy has max trailer package and the AT those Rancho shocks and they ALL exhibit different ride characteristics but they ALL still feel "jittery" even on smooth roads if the surface isn't IRON BOARD FLAT... I have experimented as recent as two days ago, my friend with the Silvy (Eagle LS2's and maybe 7k miles) is in california and I told him I wanted to see how his truck compared to mine on same roads at same speed so i took it out and it's similar in that at a constant cruise the chassis just doesn't seem settled enough to make you "RELAX".... the Denali to me, being a bit lower in ride height and having mag ride does the best at this but remember it HAS THE 6.5ft BED.... longer wheelbase, more forgiving..

 

 

telling you, it's the design, nothing can be done to ELIMINATE IT, if there was GM would've done it by now, 3rd model year with an MCE??? some are incompetent, no way they're this piss poor... i bleed gm blue btw.. it's painful to me that my truck, which rides so great around town cannot be the hwy cruiser I want it to be so that it enrages me on the open road.. so much for having a full size truck and driving to florida, or the corvette museum in comfort.. i misjudged the ride.. i have been in these trucks for THREE YEARS and maybe the one tire of mine being out of balance brought me into this thread and skewed my view of them but i am not happy..

 

I got rid of my '08 AT (the first year they made them) because it was an extended cab and i could FEEL the frame twisting over rougher roads in between the front and rear door because there was no "B" Pillar... now i am wishing for the ride of that truck back lol..... we are our own worst enemy... we ask ask ask and BAM! we get these...

 

 

Somebody mentioned that they spoke with an engineer and how the engineer complained that people want these trucks to handle like corvettes etc etc.. and I think that's what happened... they made the chassis too unforgiving and we own them so deal with it or lemon law it... anyone else have a better idea? i have 38 mos left (probably 34 or so given their pull aheads) so i will just grin and bare it as i only pay $378/mo without a penny out of pocket on a $51k truck.. Had my payment been $450 or more? it would probably crush me (mentally) and i would get out of it.. but for $98 bucks more a month than I was paying for my wife's Equinox LTZ that stickered at $36k HOW COULD I COMPLAIN? btw, she LOVES the truck so what am i doing here? I have my own daily and a Vette lol......

 

And for anyone swearing it's this or that causing the RIDE to be unsettled as it is at times over certain surfaces (which is what many of you are complaining about, rightfully so but we may be misrepresenting some of these calling it a "vibration"), you're making yourself believe something to feel better... it's the design and that's it.. because all else would be absorbed in the suspension/frame/body bushings/mounts etc and it would be acceptable... these trucks are so quiet inside now that we notice EVERYTHING.....

 

unsettled ride = "vibration" as the suspension tries to cope with the issue.. jitteriness is how i best describe my truck's ride... it feels like it's riding on top of the tires and road and if you jerk the wheel you would just "slide" but in actuality it handles extremely well and is planted as far as the tires will take it.. I can't imagine how ridiculous one of these on the 22's handles... must be (feel) as good as my vette...

 

the jitteriness of the ride makes the water shake in the glass in the center console cup holder on the hwy.. which i watched on youtube a hundred times and caught myself looking at in my own cup holders.. that's not vibration, that's a jittery ride... and given all these trucks have different spring loads and shock valving, they all have that "jitter".. some combinations hide it better than others. that what comparing 4 of these in different configs has shown me..

 

there are 100 other reasons for "vibrations" including tire/balance driveshaft etc etc, but i honestly believe after experiencing this issue myself then being able to go BACK and drive my friend's trucks and speak with them about these issues as recently as last night (none of which who are happy with their trucks as all exhibit some form of resonance in the chassis at different speeds they also refer to it as "vibration") we (GM really, but whatever) are only trying to "treat" the symptoms we tell them we are experiencing with our own SUBJECTIVE interpretations of this disharmony within this generation/design..

 

tough... to accept. it really is.. as we love this company and we are loyal. you're either a GM guy or you're not.. I have owned many others but GM outnumbers them probably 5 to 1 in this household and my family/friends... hopefully they get the next one more pinned down. or i will never do this again, not even at that ridiculously low monthly payment (maybe that's why they had $3k lease cash on top of all other rebates last month on a few trucks lol)

Stiffer is not always better with truck frames, some degree of frame flexing is actually desirable - maybe they should go back to more flexible C channel (not fully boxed) frames and softer body mounts.

No I absolutely did not pay MSRP, however, MSRP is what GM considers their selling point of their vehicles, incentives are basically a sale price, because incentives change and dealers act differently depending on where they are in their monthly quota, MSRP is considered the legal Value of the truck (Thats why GM uses MSRP to MSRP trade on a buy back).

 

Basically you never know if you will be able to get the same deal, so the highest value is the accepted value. Don't get me wrong, MSRP is generally not what you'll get out of a manufacturer if you fight with them. Most people don't want to fight and will what they paid for it.

 

There are methods to recover more in damages ie: the current replacement cost. For example, and I have no problems admitting this, I got the deal of a life time on my truck, I caught the dealer with a screwed up listing and and got 41.94% off the MSRP, but then added some protection packages at the time of purchase. I will NEVER be able to get that again, so the replacement cost/ "value" is much higher than what I paid, and legally I am entitled to that.

 

If you want to use a lower value than MSRP for the truck, the legal method would be "replacement cost" and this is to include all taxes and fees associated with replacement.

 

I won't get into all of the legalities of it, as I could go on and on, but here you go

I don't know, but if I had know about this problem/ forum/ thread before I bought, even with the deal I got, I still wouldn't have purchased this POS. You're supposed to enjoy driving a new vehicle.... I dread it

[paxtonman]

I disagree with the thinking we are all buying trucks to either pull or carry massive amounts and everything had to be made stiffer. My Crew Cab 1/2 ton short box is a people hauler and throw some luggage in the box, dog kennal, etc. They know this. I don't know about the rest of you but like jesse, I absolutley hate this thing. I went from a vibrating Sil to a vibrating Sierra with no headlights. GM had projected profits 3 qtr of $1.16 per share, actual was $1.50. They made an incredible amount of money from people like us and now just want us to go away and shut up. I am tired of the "it's normal". No, it's not. If it is normal why don't the Ram, F150, Tundra all drive like this? In terms of "driving" they should all be about the same. Forget the motors, options, bed size ,etc. They should all "drive" the same. My 14 was perfect and I guess I was naïve when I bought the 15 thinking this was a small issue. But to anyone buying one of these now who admits to reading this forum, WTF are you thinking???
