NHTSA's VIN data lists these trims for the 2012 CTS. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 67 complaints with NHTSA about the 2012 CTS. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2012 CTS over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) notified the agency on July 2, 2014 that they are recalling 554,328 model year 2003-2014 Cadillac CTS vehicles manufactured August 16, 2001, to April 28, 2014, and 2004-2006 Cadillac SRX vehicles manufactured March 20, 2003, to August 11, 2006. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Risk: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 15, 2014. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14172.
GM IS RECALLING CERTAIN MODEL YEAR 2012 CADILLAC CTS VEHICLES MANUFACTURED FROM OCTOBER 21, 2011, THROUGH OCTOBER 26, 2011. THESE VEHICLES MAY HAVE A CONDITION IN WHICH THE POWER VACUUM BRAKE BOOST PUSHROD RETENTION NUT MAY NOT BE TORQUED TO THE PROPER SPECIFICATION. IF THE NUT IS NOT TORQUED TO THE PROPER SPECIFICATION, THE NUT COULD LOOSEN AND ALLOW THE PUSHROD TO SEPARATE FROM THE BRAKE PEDAL.
Risk: THIS COULD RESULT IN A LOSS OF ABILITY TO BRAKE AND a vehicle CRASH WITHOUT PRIOR WARNING.
Remedy: CADILLAC DEALERS WILL INSPECT THE POWER VACUUM BRAKE BOOST PUSHROD RETENTION NUT, AND IF NECESSARY, TORQUE THE NUT TO THE PROPER SPECIFICATION. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON NOVEMBER 1, 2011. OWNERS MAY CONTACT CADILLAC AT 1-800-458-8006.
Carmakers sent NHTSA 1,565 service bulletins and notices that cover the 2012 CTS, the latest on Sep 4, 2026. They tell dealers how to fix known issues.
The parts they mention most: equipment (651), electrical system (306), engine and engine cooling (189), engine (154), power train (131).
NHTSA hasn't opened a defect investigation that covers this model year.
Maintenance
Oil
The owner's manual gives the oil and how often to change it. We show oil facts only once we've checked them against the manual, and we haven't yet for the 2012 CTS.
