Of the more than 35,000 vehicles serviced each day by Valvoline Instant Oil Change, nearly 1 in 4 has an open manufacturer recall, according to an analysis by Carfax.

Thanks to a partnership between the two companies, Valvoline will now check vehicles serviced at any of its locations for open recalls using myCarfax.com to send a courtesy email to customers if any recalls are found.

“The sheer number of our customers who are driving vehicles with open recalls is surprising, and we’re happy to do our part to help,” said Rob Stravitz, vice president of marketing for Valvoline. “We have a great partner in Carfax that is a leader in the effort to keep people informed about open recalls. Powered by VIN-specific open recall information from myCarfax.com, this customer service initiative is a quick, easy and trusted way for us to contact affected customers and uphold our commitment to their safety.”

Carfax data suggests there are more than 47 million vehicles in the U.S. with unfixed recalls. Because drivers often are unaware of recalls on their vehicle, a link in the email they receive will take them to myCarfax.com so they can see more recall details and get notified of future recalls after setting up a free account.

“Staying informed about recalls and taking action on them is vital to maintaining the safety and performance of our vehicles,” said Vern Poyner, general manager at Carfax. “Almost 3 million people already turn to myCarfax.com for open recall information and other vehicle maintenance needs. Working with VIOC to alert their customers about safety recalls is a total team effort that will help keep our roads safe.”
