Cadillac outranks Mercedes and BMW in latest reliability study

Recent J.D. Power data for 2026 reveals an unexpected shake-up in the premium automotive segment. Cadillac secured fourth place in the overall reliability rankings with a score of 175 problems per 100 vehicles (PP100), surpassing both Mercedes-Benz and BMW and significantly beating the industry average of 204 PP100.

Mercedes saw its position decline due to numerous software and electronic glitches. The MBUX infotainment system, over-the-air updates, and complex touchpads have drawn particular criticism. An additional factor was plug-in hybrid models, which in 2026 were identified as the least reliable powertrain type, scoring 281 PP100.

BMW performed more consistently, with 198 PP100—slightly better than the industry average. Models equipped with the inline-six B58 engine show excellent mechanical reliability. However, even here, the push toward digitization and the removal of physical buttons have become a source of minor but frequent issues.

Cadillac benefits from a more conservative approach: proven GM platforms, naturally aspirated V6 engines, and a measured rollout of new technologies. The XT6 stands out, recognized as the most reliable premium midsize SUV.

In an era where automakers are betting heavily on complex hybrid and electric systems, simpler architecture has become an advantage. Cadillac demonstrates that reliability today isn't just about build quality, but also about striking a sensible balance with technology.

In the race for digital innovation, many brands risk stability, while a more restrained strategy can offer a genuine competitive edge.
