Summary Verdict

The 2019 Cadillac ATS demonstrates good overall reliability, with the 2.0L Turbo engine being the most common source of reported non-wear-and-tear issues, primarily related to the turbocharger and cooling system. The 3.6L V6 and manual transmission variants are generally very robust. Transmission issues with the 8-speed automatic are infrequent but can be costly to repair. Electrical gremlins, particularly with the infotainment system and occasional battery drain, are also noted. The suspension, exterior, and interior components are largely free from widespread problems. Regular maintenance and addressing early signs of the aforementioned issues can ensure a dependable ownership experience.
