I recently purchased a 2015 Sierra Denali quad cab Standard Box 2wd. 62L
I have a violent shudder during light acceleration seems to occur around 30MPH between trans shift points during light acceleration, once the shudder occurs you can remove or increase throttle pressure and it will go away.
The shudder feels as if it is power train related, I first noticed it at 233 Miles and at 7600 miles it is still there. The dealer stated that they had called a tech advisor at GM and had been advised that it has come up and so far they think it is an exhaust vibration and once they figure it out they will schedule me back in. I do not feel it is an exhaust vibration as the entire vehicle shudders as if the converter is trying to lock or as if there is friction disc chatter, It feels like a definite powertrain concern yet no codes or faults.
Anyone experience this or know the solution ? I had an 08 Sierra Denali 6.2L and never had any type of concern like this.
