It has been many years since I have had a new vehicle spend so much time in the shop. Almost immediately I had problems with the rear end. They performed a bulletin on it but it was back in the shop a few weeks after with the same problem. Then they replaced the whole rear end. Next it was check engine lights. Then they replaced the gas tank. Next the rear end problem came back. Then came more check engine light problems. And then less intrusive problems started happening like the finish chipping off the most used control knobs, problems with the driver's power seat, problems with the nav system. I was ultimately pretty disappointed in this great looking Cadillac.
The looks, handling, and power.
Fix the engineering problems with the rear end, use better quality materials on the dashboard, improve the gas mileage.
