Digital Auto Care Factbook 2018 - 48

Replacement Rates for Motor Vehicle Parts and Jobs
Replacement rates reflect the percent of cars that had a relevant part replaced or service performed during the year. Vehicle age has
a significant impact on the rate at which different components are replaced. Newer vehicles typically do not experience component
failure to the same extent as older vehicles, while vehicles in an intermediate age ranges often require much more maintenance and
repair as their mileage increases. Vehicles in the oldest group also need work, but owners tend to avoid non-essential repairs and
therefore rates decline.
