Shake or Vibration Issues

[Kickapoo]

Dropped my 2015 high country with 28500 miles off at the dealership yesterday. They road force balanced the tires and said that helped, but still vibrates. They kept it overnight so they can put it on a machine and see if they can pinpoint the issue.

So I'm needing a little input here.. I previously had a 2014 Chevy Silverado that hat a little bit of the shake that this thread refers to and I traded it off on a Ram 1500. Now that the new 2017 are out I'm thinking about going back to the Silverado. Nothing wrong with the Ram, just liking some of the new stuff on the Silverado. Is it still hit or miss about getting a new Silverado that shakes? Should I just keep the Ram?

Keep your Ram. Take another look when the 2019 drops.

Keep your Ram untill 2018 model, there is the new 10 speed tranny, as well as a new frame, that will possibly help solve these vibrations!

 

I too am holding off untill they solve this issue....not gonna drive a vibrator...no way!

Just picked my truck up from the dealership. Road force balance and balanced my drive shaft. Did a pico test and everything came under .02g. It's better, but I feel it could be smoother. Service techs words were "it's as good as it's going to get".

Skip the idea for now. I drove 7 (Seven!) different 2017 models between service loaners and new potential replacements. Each one shook in it's own special way (albeit to a lesser degree than my own). GM has a law suit coming its way from my attorney. Really a let down as I am not interested in the other Makes.

The Torque Converter was replaced due to some shudder in V4 switching to V6 under light throttle. I was excited hoping that some of the other random vibes were shudder also, they were not.

 

Still vibrating.

 

I took the truck to a Sierra dealership and just sat down with a service analyst....

 

They have 4 trucks that they are currently working to fix. They are swapping parts out one by one according to GM's direction. Run the PICO, GM analyzes and provides repair options. Wheels, tires, axles, axle housings, transmission, torque converters, driveshafts, front drive shafts ..... all replaced on a customer's vehicle with no solution to the vibrations.

 

Confirmed some 2014, 2015, 2016, 2017 have this problem.

 

Confirmed GM has no idea what the problem or a solution is

Back to the dealership today.

Good luck.

If I had the budget, time, and the tools Gm engineers have, these vibration issues would be sorted by now!

 

However if they exist in the engine (v4-v8 mode) switch, transmission (shudder) from torque converter being locked up early for mileage claims, and possible a wierd transfer driveline imbalance.

They will not redesign internal hard parts at or nearing the end of model year run.

 

A successful company always, continuesly keeps improving their products. GM however is selling these trucks with full knowledge of these mechanical, and vibration problems.

 

I personally believe their is a stacking problem of critical rotating parts not machined correctly, add that to a high tensile frame, which allows frame beaming to occur and transfers all this energy to the cabin and passengers.

Well if GM don't know what is causing it now then who is to say next generation may be more of the same .

The Next generation will have revised Cab Mounts! They are fully aware of the problem.....mitigating the small disturbances that are transcended through the Frame and cab structure is all they can do....It's not a safety issue and trucks do ride rougher than cars.

 

Everybody laughs but I did a cheap ass non-scientific experiment and I am fairly certain it's the problem. Isolating the engine like the older "W" bodies with cradles would have cost more but significantly reduced the new powertrain VIBES! It ruins the on road steering feel but the isolation was needed for these powertrains and the Electric steering ruined the feel anyways.......

 

Last I heard from a birdie they were looking at both for new Generation mainly the "Cab Mounts" It will ultimately be a money thing in the end........

My guess is GM engineers know what the cause is and what the fix is. Guess also the fix is expensive. Maybe too expensive for GM to step up and make it right. Fuk you GM for selling me a $45K truck that you knew had issues.

Pretty Much! Ford is selling the Ecoboost with same intentions/ thought process! Pick your poison?
