Vibration Under Hard Acceleration?

[nvedamuthu]

I have a 2011 Yukon Denali Hybrid and any time I accelerate hard from a standstill there is a vibration above 3000 RPM. Has anyone else experienced this?

I don't know if I would call it a vibration, however I have a weird sound coming from the passenger side like a rattle sound like something inside the cab is loose. Describe your "vibration".

I had a vibration under acceleration also.
For me it turned out to be a bad rear universal joint.
Replaced it, put Lucas Sticky Red grease in the slip-yoke.... no more vibration.
Hope this helps.

Yup, vibration, rattle, from passenger side.

OK...after readin ur last post..... realized that there wasn't a vibration that you could feel as if a wheel was unbalanced.... rather a piece of metal is vibrating/rattling..... totally diff. "vibration" all together.

Uhhmmm.... Warranty???

GM Customer Service... Sucks

Thanks for all your "help". I sent you a message more than a month ago and haven't gotten a reply. Not the type of service I expect for buying such a nice truck.

Yup 2008 tahoe hybrid. Same noise under acceleration sometimes. Kind of a vibration/rattle from the passenger side.

Sad to see GM customer service totally dropped the ball on this one... and to see the problem exists through a spectrum of years.
Why DO they wait for people to crash due to sloppy design flaws before they consider helping loyal customers out???
