NHTSA's VIN data lists these trims for the 2011 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 108 complaints with NHTSA about the 2011 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 2011 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.
General Motors LLC (GM) is recalling certain model year 2011 Cadillac CTS vehicles manufactured October 18, 2010, to June 2, 2011. In the affected vehicles, vibrations from the drive shaft may cause the vehicle's roll over sensor to command the roof rail air bags to deploy.
Risk: If the roof rail air bags deploy unexpectedly, there is an increased risk of crash and injury to the occupants.
Remedy: GM will notify owners, and dealers will replace the rear drive shaft assembly, free of charge. General Motors distributed an interim letter to owners on August 27, 2014. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14233.
Carmakers sent NHTSA 1,525 service bulletins and notices that cover the 2011 CTS, the latest on Sep 4, 2026. They tell dealers how to fix known issues.
The parts they mention most: equipment (630), electrical system (305), engine and engine cooling (191), engine (147), power train (135).
