I love or should I say "loved" this car for the many years I have owned it. The car performed perfectly until 55,000 miles when it began drinking up a qt of oil every 1,000 miles. No leaks, and No Smoke, just a quart of oil gone.
The worst part about it was I didn't figure this out until the car was down 4 qts and started to make lots of noise. No LOW oil level or pressure indicator.
Sorry GM, I traded in the CTS for a NEW Lexus ES350. Maybe I'll be back in a few years, but for now I'm gone.
Radio, trip computer, comfy seats, great performance
No place for my sun glasses! Where did all my oil go? They should do better testing on these engines before putting them into production. Do your research before buying a 2004-2008 CTS with the 3.6L
