2012 Chevrolet Impala LTZ 4dr Sedan (3.6L 6cyl 6A)
Decided to purchase the Impala from my local Chevy and Buick dealer. The car had 15,000 miles when purchased. The car was first put into service in Hawaii as a rental . When I turned the radio off I could hear a whistel or buzz from 2100 to about 3000 RPM. Turns out there is a service bulliten on the 3.6 for buzzing, humming or whisteling from 2000 to 4000 RPM, bulletin PIP4956A. This covers the replacement of the intake manifold. Just picked the car and and no more noise. All work was performed under warranty. I really do like the car and who can complain about 300+ HP on tap.
Get up and go, front seat room, remote start- great when its below zero- just push the button. Beutiful looking car.
More rear seat leg room. My spouses '13' Equinox has great leg room. I would prefer 6" less trunk room and more back seat leg room.
