Check engine Light just pop up , vehicle has been stalling and running a little ruff for a week, I have to take it to the dealer not sure how long they will have it there, Had On Star run a diagnostic check they also told me to contact the Cadillac Dealer so that they can check it out it seem to have something to do with he emission according to the On star results. You can, enjoy you vehicle because it always in the shop for one thing or another I already have an appointment for Two not One Recalls on this vehicle You just fell like your begin rip off all the time. I've already had this vehicle in the shop on Two prior occasion thank goodness i have the warranty to cover these issues because their is no way that you could afford these cars.

CTS Performance 3.6L

  • Automatic transmission

check engine light came on, poor idling, poor MPG. Took to the Dealer to be inspected, ruled out the emission system needed to be serviced. Replaced Defective/shorted Air Injection Pump. Repair was covered under Cadillac BRB limited 50k 5 year warranty.
