2014 Tahoe LTZ w towing package. Vibrations...

[Mama1961]

Anyone else notice that their vehicle vibrates at 30mph and then. Again at 45?
Tech says it is normal for the engine transitions from 4 to 8 cylinders and back. I need some real info. Just bought this used, 32,000 miles and it has been in the shop 4 times already... Want to know if it is normal to feel these vibrations, because I can't believe it

I have the same vehicle, only a 2012 and I feel the vibrations as well. I have my display showing when my car changes from 4 to 8 cylinders and notice that the vibrations are when this is happening. You can change you display to see if that is when you feel this.

Thank you for responding. Could you tell me how to change the display to show the transition from 4 to 8?

My truck has a button on my dash that has a picture of a road on it. When I press it one of the things it show is the fuel economy and another show instant fuel economy and it changes from V8 to V4 while I'm driving. Check your manual for instant fuel economy. It helps me learn how to drive to keep it 4. This message shows where the mileage/ info center is.

Thanks again, I will look into that

I just looked up your manual. It looks like you have the same four buttons that I do. The top one in the road button, the one below it is a button with a picture of a car with an exclamation point. The top button is the one you press until it show you when you are using 8 or 4.
