CARFAX reports that its maintenance data shows nearly half of vehicles on the road are overdue for a tire rotation and about 30% of vehicles are overdue for an oil change.

In addition, about one in five vehicles on the road has a safety recall that hasn’t been repaired.

“A well-maintained vehicle will last longer, cost you less during ownership, and be worth more when it’s time to sell,” said Paul Nadjarian, General Manager of CARFAX Car Care.

Automakers base their recommended service intervals on time or mileage, whichever comes first.

“It’s troubling to know about one in five cars is overdue for both an oil change and tire rotation,” says Nadjarian.

“This routine maintenance makes your vehicle more reliable. Our free Car Care program helps vehicle owners stay on top of their vehicle’s unique maintenance schedule with helpful reminders for upcoming service recommendations.

“Our goal is to help drivers make their maintenance decisions with more confidence.”

In addition to just running better, also consider CARFAX data shows that a well-maintained car is worth an extra $2,000 om average in resale value over one that hasn’t gotten its TLC.

CARFAX Car Care is a free tool to help consumers to better understand when it’s time to service a car. It tracks service needs, with timely service reminders and notifications of new recalls.
