Toyota has announced recalls for another 1.6 million cars with fuel line and brake problems as of Oct. 15.

This is yet another blow to the automaker, which, as The Wall Street Journal noted in its coverage, “has been working to restore its reputation after recent safety troubles.”

In the past year, the company has recalled more than five million vehicles in the United States alone. Other auto giants, such as Honda and General Motors, have also issued recalls covering an unprecedented number of vehicles, leading to greater scrutiny of the auto industry across the board.

Faulty Fuel Pipes

The flaw that applies to more American-owned vehicles has to do with the fuel delivery system in 759,000 Toyota and Lexus cars. Of those, 423,000 are located in the U.S.

Recalled models include Toyota Crown, Toyota Crown Majesta, Toyota Mark X, Lexus IS, Lexus GS and Lexus LS vehicles manufactured between January 2005 and September 2010.

The fuel pipes in these vehicles may leak, increasing the risk of fire.

The flaw was first identified in a 2010 report, but officials say a single report was not considered adequate cause to issue a mass recall.

Master Cylinder Flaw

The other recall is regarding a flaw in the master cylinder of some cars’ braking systems.

Brake fluid levels are one of the two preventive brake system checks drivers are encouraged to have done regularly. The other aspect of regular brake maintenance, changing brake pads, should be done before the pads are one-eighth of an inch thick.

However, Toyota officials say that the affected cars have a faulty rubber seal ring that could cause cars to hemorrhage brake fluid, presumably too quickly for drivers to notice the problem in the course of regular maintenance.

This could compromise braking ability, as Ashlee Kieler noted drily in her article for Consumerist. “Here’s the thing about brakes, they’re supposed to actually stop a vehicle,” she wrote the day of the recall.

The recall applies to roughly 802,000 Crown Majesta, Crown, Noah and Voxy models from between June 2007 and June 2014. The Crown Majesta and Noah are both sold in the Asian market.

An additional 190,000 cars are being recalled in Japan over their fuel evaporative emission control units.

Toyota maintains it is not aware that any fires, crashes, injuries or deaths have been related to manufacturing problems in the recalled models.
