In the first part of May of 2012, a United States senator representing the state of California sent a letter to the four largest car rental agencies in the nation, requesting that they discontinue the rental of vehicles that have been recalled for safety issues but not repaired. Of the four leading rental car companies in the United States – Hertz, Enterprise, Avis, and Dollar/Thrifty – only Hertz had adopted the policy previous to her sending the letter, which promised to publicly name any companies that did not adopt the policy before the imposed 30 day deadline is reached. Recently, Enterprise Holdings Incorporated announced that it will join Hertz in ceasing the rental of all cars affected by safety recalls that have not been resolved. According to a letter sent in response to the senator’s request, Enterprise Holdings, which owns and operates Enterprise, Alamo, and National rental car agencies, said that it would no longer rent recalled vehicles with unresolved safety issues. The company’s representatives added that Enterprise Holdings will work for the passage of a federal regulation that requires all rental car agencies to adopt this policy. According to a spokesperson for Enterprise Holdings, the company had previously allowed recalled vehicles to be rented when the National Highway Safety Administration’s recall notice suggested an interim measure that could reduce the danger created by the potential safety issue until it could be take in for repairs.
