Three of the nation's four major rental car companies refused to agree to a blanket pledge to not rent or sell unrepaired recalled vehicles, safety advocates said Tuesday.
Sen. Barbara Boxer, D-Calif., said only Hertz Global Holdings Inc., with 8,500 locations in 150 countries, had agreed to the pledge.
She urged the other three major companies to follow suit.
"You can just see the loopholes being created," Boxer said at a Capitol Hill press conference. "I'm going to keep the spotlight on."
Enterprise Holdings, parent company to Enterprise, National and Alamo, wants an exemption to rent some unrepaired vehicles if customers get notice first.
