Which Kia Niro years should I avoid?
The Kia Niro build year that fails most for its age is 2019: index 108.2 (95% CI 104.9–111.6) against the model's own age norm of 100 (2019–2024, n = 31,242).
Build year matters for the Kia Niro: 2019 Kia Niros fail more than their age would predict, 2016 ones less.Years whose confidence interval includes normal are shown without a label.
