The car developed a vibration between 65-75 miles per hour. Similar to problems expressed by others on this site. Car was down to last 3,000 miles or warranty, so I took an aggressive approach with the dealer.
The dealer first recommended new tires. I put on the same brand (Michelin Symmetrys) as original equipment. Also replaced two slightly bent wheels. Didn't help. Dealer installed new control arms. Didn't help. Dealer power balanced the tires. Didn't help. Dealer installed new trans-axles (drive shaft from the transmission to the wheel). FIXED IT!!
I agree on Cadillac losing it's touch for quality in some vehicles. But they were phasing out old designs and messing with new ones, so it's standard. I have a 90 DeVille. I love it. Nothing wrong with it, but a switch in the driver's door jamb, and that's understandable, seeing as it's used every time you open or close the door.
