NHTSA's VIN data lists these trims for the 2015 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 49 complaints with NHTSA about the 2015 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 4 recall campaigns for the 2015 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.

Risk: An inflator rupture may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.

General Motors LLC (GM) is recalling certain 2014-2015 Cadillac CTS-V Sport vehicles equipped with 3.6L Twin Turbo V6 engines. The roll pins in the rear-axle differential may fracture.
Risk: If the roll pins fracture while the vehicle is in motion, the rear wheels may lock up and the driver can lose control of the vehicle, increasing the risk of a crash.
