Nearly Half of U.S. Drivers Skipping Critical Car Maintenance, CARFAX Reports

A new report from CARFAX reveals that 41% of U.S. vehicles are behind on at least one major maintenance service — an alarming statistic as millions prepare for holiday travel. These lapses include overdue brake, steering, transmission, and engine maintenance, as well as neglected air filter replacements and tire rotations. CARFAX warns that this widespread vehicle neglect increases the risk of accidents and breakdowns during one of the year’s busiest travel periods.

For insurance claims adjusters, this data is a clear indicator of potential surges in auto claims tied to preventable mechanical failures. From blown tires to engine stalls, the implications extend to liability determinations and subrogation opportunities. The report also highlights behavioral trends in vehicle upkeep that could inform underwriting models and seasonal claims forecasting. As drivers hit the road with vehicles that may be unsafe, adjusters should anticipate a rise in roadside incidents, especially in colder states where battery and tire issues become more acute.

The report underscores the value of education around routine maintenance — not just for vehicle longevity, but for reducing claims frequency and severity. With CARFAX offering free tools to help drivers track service needs, insurers might find collaborative potential in integrating such resources into policyholder engagement strategies.
