During accel and cruise at around 17-2100 RPM there is a pronounced harmonic vibration felt.
Any Ideas?
Car has 18000 miles and is an Auto V6

Did you know that every Mustang V6, 2005+ vibrates around the speed of 70 mph?

I had the answer if it was a stick..... Flywheel. at least that's what it was on mine!

In addition to my 2007 V6 Mustang Convertible I have a 2007 Altima 2.5S and compared to the Altima I think my Mustang vibrates at all RPMs. Despite the fact that my Mustang is a much "rougher" ride, I still enjoy it more. At the same time, going from the Altima to the Mustang it feels like I need to balance the tires. My "93 Ford Ranger had the same vibrations.

Isolate it and then get back to us. It could be anything, it really varies car to car.

May be the driveshaft. All of our cars do it pretty much.

I would take the vehicle into the dealer right away under warranty and have it check out!
Test drive it with the service manager at your side! IMO
