Spain’s aging car fleet drives up fatal crash risk

A study by the Fundación Línea Directa in collaboration with Centro Zaragoza found that Spain’s average passenger‑car age has risen to 14.6 years, a 58 % increase since 2010. Vehicles with poor mechanical maintenance present a five‑fold higher likelihood of fatality in accidents, and the death toll linked to such neglect reached at least 670 between 2015 and 2024, with more than 23,000 injuries. Older cars also show 70 % more defects than vehicles less than four years old, and repair costs have risen 22 % over the past five years, prompting many owners to delay essential work.

The report also notes that 17.9 % of inspected cars fail the first ITV (technical inspection) and average two serious faults. Meanwhile, European manufacturers are extending oil‑change intervals—now often 20‑30 000 km—thanks to advanced synthetic lubricants, though drivers are urged to adjust schedules for heavy use, off‑road driving, or short trips that prevent the engine from reaching optimal temperature.

These findings highlight the safety implications of an aging, under‑maintained vehicle fleet and the need for more rigorous maintenance practices to reduce road fatalities.
