DETROIT – DaimlerChrysler AG on Friday recalled all 460,000 of its popular, retro-styled PT Cruisers because of a fuel pump leak.

The PT Cruiser has been one of the most successful vehicles in the Chrysler Group’s lineup since it was introduced two years ago.

Officials discovered the leak after a government crash test in May, Chrysler spokeswoman Ann Smith said. The leak could ignite a fire if sparked, she said.

There are no known incidents or customer complaints related to the problem, DaimlerChrysler said. The company will install a secondary seal to the top of the fuel pump module.

A quarter of the 464,315 vehicles being recalled, all from the 2001 and 2002 model years, also need repair of a separate problem with the underhood fuel supply line, which may rub against the air conditioning service port.

That could result in a fuel leak, the automaker said.

Owners will be notified by mail.
