Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 14 tested variants for this model year.
The dominant complaint pattern for the 2011 CTS centers on the powertrain, airbag system, and electrical system, with all three drawing similar complaint volumes. On the powertrain side, owners describe transmission concerns including rough shifting and engagement issues. The airbag complaints are notably centered on the passenger seat occupant sensor, multiple owners report the airbag warning light staying on, with some finding that replacement parts are no longer available from the manufacturer, leaving the system in a non-functional state. Electrical complaints frequently tie back to water intrusion: owners describe leaks entering the cabin from the driver and passenger sides, which then trigger persistent battery drain, radio and climate control malfunctions, and ignition switch problems. A smaller number of owners also mention underbody rust discovered during inspection.

With Injuries
By System
The 2011 Cadillac CTS has 3 recalls, the most serious being a driveshaft vibration problem on all-wheel-drive models that can trigger the roof rail airbags to deploy without warning, raising the risk of a crash and injury.
The ignition system also has a recall: if extra weight on the key ring causes the ignition to slip out of the run position while driving, the airbags may not deploy in a crash. Until this recall is repaired, owners should remove everything from the key ring except the ignition key itself, including the key fob.
