NHTSA's VIN data lists these trims for the 2015 XTS. 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 14 complaints with NHTSA about the 2015 XTS. 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 3 recall campaigns for the 2015 XTS 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.

General Motors LLC (GM) is recalling certain model year 2015 Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain vehicles. The affected vehicles have front seat-mounted side impact air bags whose inflator may rupture upon its deployment.
Risk: In the event of a crash necessitating deployment of one or both of the side impact air bags, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. Additionally, if the air bag does not properly inflate, the driver or passenger is at an increased risk of injury.
Remedy: GM will notify owners, and dealers will replace the side impact air bag modules, free of charge. The recall began on October 19, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, Cadillac customer service at 1-800-458-8006, or GMC customer service at 1-800-462-8782.
