Ford; Toyota Investigating Brake Issues With Hybrids

Ford is investigating a software issue with two of its hybrid vehicles, the Mercury Milan and Ford Fusions while Toyota is looking at similar problems with its popular Toyota Prius.

The automaker says the problem occurs in transition between two braking systems and at no time are drivers without brakes.

The decision to fix the 2010 model cars came after a test driver for Consumer Reports magazine experienced the problem as he was driving a Fusion Hybrid.

Ford spokesman Said Deep says braking power seems to drop away as the car makes a transition from regenerative brakes to the conventional system. The Ford hybrids have regenerative brakes, which capture energy from braking to help recharge the battery, in addition to a conventional system that stops the car using hydraulic pressure.

Deep says Ford will notify the car owners to bring their cars in for a software fix. He said there is no safety problem with the cars. The automaker called the repairs a "customer satisfaction program" and said it was not a full-fledged recall. Deep said Ford reported the problems to a U.S. safety agency, the National Highway Traffic Safety Administration.

The move comes on the same day that NHTSA began an evaluation of braking problems on the 2010 Toyota Prius hybrid. With the Prius, antilock brakes can fail momentarily while the car transitions between its gasoline and electric motors.

Ford told dealers about a fix on Thursday. They already had the software to repair it in case it came up, Deep said.

Toyota's woes keep getting worse, even with the head of the company finally offering a mea culpa and steps to prevent future problems.
