Nice Car with a few defects
By Allen Lobb on


2006 Cadillac STS V6 4dr Sedan (3.6L 6cyl 5A)


Purchase the car used with 38,000 miles. Engine consumes a quart of oil about every 3000 miles. Using the oil recommended by Cadillac which is Mobil One-5w30. No signs of oil leaks, no smoke out of the exhaust pipe. Cadillac drive OK if you don't mind the popping sound in the driver seat when turning corners. Also, sometime the lights in the dash below the speedo/tach go out. Our third Calillac, the last two had electrical problems. After 8 years with Cadillac, this will be our last one.

Best Features

Great looking automobile, when we located it on the Dealer's used car showroom floor it appeared new.

Worst Features

Cadillac need to step up and recall these cars for the oil problems. We have owned other GMs such as our Corvette & Silverado and others for years and never had to add oil to any of those vehicles.

Mr. Loeb may not be aware, when he commented on the problem with the drivers seat, that there is Technical Letter for correcting that problem. There was a factory defect in the tolerance between the seat and the rail the seat travels on. I purchased my 2006 STS new and have had that correction performed satisfactorily.
