Currently, more than 63 million vehicles with open, unrepaired recalls are in use across the country, a 34% increase from 2016, according to Carfax.

The annual research also suggests that recalls affect nearly one in three vehicles in Texas, the highest rate in the nation. Behind Hawaii, the other Gulf Coast states of Mississippi, Louisiana, and Alabama round out the top five U.S. states with the highest vehicle recall rates.

In addition, people in California, Texas, Florida, Pennsylvania, and New York have the most vehicles with open recalls.

“Reducing the number of open recalls on the road is an ongoing effort,” said Larry Gamache, communications director at Carfax. “Safety is our number one concern. Carfax, manufacturers, and government are working together to make it easier for drivers to get accurate information and timely alerts about open recalls. It may be inconvenient, but people driving recalled cars should make getting them fixed a high priority.”

The new data also suggests that family life may be a factor for some vehicle owners not knowing about a recall or getting it fixed. Minivans and SUVs — family-oriented vehicles — are the ones most likely to have unfixed recalls.
