NHTSA's website also lets consumers proactively search for recalls and get notifications. Already, NHTSA and the state of Maryland piloted a program that alerted consumers to open recalls when they renewed a registration, which uncovered almost a million open recalls between April 2018 and January 2020. And as part of a settlement related to the massive Takata airbag recall, some automakers used social media, advertising, and in-person events to track down owners of vehicles that needed their airbags replaced. CR's Wallace says that in addition to updating registration data, consumers should also update their addresses with automakers to ensure that they get timely recall notices. "Typically, you can change the address on file with a car company by going to the automaker's website, creating a new account or signing in if you already have one, and updating your personal information," he says.
