Reliability ranking: Lexus, Kia and Tesla lead up to five years

Published on July 30, 2026 | Translated from Spanish

What Car? magazine has published a reliability analysis for vehicles up to five years old, evaluating brands based on failure data and repair costs. Lexus, Kia, Tesla, and BMW achieved scores above 94%, positioning themselves as solid options for those looking to avoid costly mechanical issues. The study helps buyers make informed decisions, highlighting that trust in a car depends not only on price but on its real-world durability record.

Technical data: what the reliability ranking actually measures 🛠️

What Car?'s methodology is based on owner surveys and workshop records, analyzing failures in engine, transmission, electronics, and suspension. Brands like Lexus stand out for their conservative engineering and rigorous quality controls, while Tesla shows consistency in its electric powertrains. Kia, for its part, has improved thanks to standardized manufacturing processes. In contrast, Alfa Romeo and Land Rover appear at the bottom of the rankings, with low scores due to recurring problems in electrical and mechanical systems, suggesting that their aesthetic appeal does not compensate for a lack of robustness.

The Alfa Romeo drama: Italian beauty with a workshop soul 😅

If your dream is to own an Alfa Romeo, get ready for an intense relationship: you look at it, it breaks down. While Lexus and Kia go years without visiting a mechanic, Alfa owners develop diagnostic skills that would rival an engineer. Sure, nobody denies the Giulia is beautiful... when it's not on the lift. In the end, choosing reliability is like choosing a partner: better to have someone who works every day, even if they're not the flashiest.
