Traded a 96 Caddy for this in May. After driving a few days, found that the transmission whines loudly in the 15- 30 MPH range. This is the 4T80E transverse transmission which only comes with the 292 on the Super and the Cadillac DTS. GM has a bulletin out on this but a design change projected for early August did not come through. Totally unsatisfactory. GM knew about this way back in 2007 but didn't tell anybody. All other aspects of the car are really good except, as noted below and disappointing MPG. My Caddy got over 30 MPG on flat land and this only gets 25. My 1984 Olds 98 still gets 27. I guess that's progress for you.
Blind side detector, rain detecting windshield washers, lane switch notification, navigator, great power, nice ride except on rough roads, quiet.
Eliminate tach and use for electronic information which is now relegated to one at a time on the speedometer. Go back to digital gas guage and speedometer. Go back to electronic lock on gas door and trunk lid. Don't sell cars with a known problem.
