Vibration at 60 - 70 mph in my seat. If I hold a pen up in my index finger and thumb on a new smooth road it shakes like I have a nervous condition. I had a 2012 LS that was smooth as silk on the road. My 2015 2SS is awesome but........ Known TSB's with Vibration issues in the chassis or drive line. Hopefully its just a wheel. It's been 4 business days and I miss my new girl. :((!!
Anyway just venting. They won't give it back to me until they isolate it since it did this right off the show room floor. I told them about it immediately. Lemon?? Hope not because she is a real beaut! The dealership gave me a 2016 Z71 to drive in the mean time. Its just not the same. I have a 2015 Silverado for the wifey. Crying in my beer right now.

Probably just a tire balancing issue.

You can get much the same thing by parking the car for an extended period without adding 5psi extra to the tires.
The tires can flatspot, and it'll vibrate until they warm up good.
Add 5psi before storage and there's no problem, just remember to air them back down to the correct pressure before you take it out of storage.

Thanks for the feedback. Its now day five. Since the car is brand new they are obligated to find the source. It is being handled as a pre delivery issue. As you can see it has factory installed upgraded wheels which is why I thought it was a wheel balance issue. The dealership said they want to make sure its not anything else because it's rare a car is shipped from GM with a balance issue. I am happy they are being careful but I barely had it a week. The vibration happens even after a good warm up and at all miles. The tires are all nitrogen filled.

Nitrogen doesn't matter. They could be filled with ANY inert gas or gases and it'd be fine.

Even new cars can have problems and issues. It sucks but at least they gave you a loaner vehicle...but they couldv'e given you a different 2015 Camaro SS while you wait for yours. I mean, these dealers use cars all the time for personal use. They could have thrown you one.

If balancing the tires does not fix the problem, you might ask them to check the drive-line. Cadillac had a similar problem years ago and the fix was to rotate the pinion yoke 180 degrees, if that did not fix it they would replace the pinion yoke....funny thing, they called it a "Drive Line Boom":surprise: :surprise:

The dealership said the tech was able to feel the vibe and after they checked all known issues with Camaro driveline/chassis they checked the tires and found two wheels out of balance. They did not just assume it was tires thankfully so I feel confident that they got it right. They had it on the rack for a week checking everything at least that is what they said. Other than that we will wait and see. They knew about previous problems so maybe its fixed(fingers crossed).
