It’s been one series of problems after another for battery-car start-up Fisker Automotive. This time, the maker says it will have to replace potentially defective batteries in its Karma plug-in hybrid due to a manufacturing problem discovered by supplier A123.
Fisker itself plans to take steps to cover potential problems with the Karma, including offering owners an extended warranty.
The problem came to light earlier this month when a Fisker Karma delivered for testing to Consumer Reports magazine froze up and wouldn’t shift out of Park. It was quickly determined that the problem was the result of a short circuit in the battery that put the vehicle into failsafe mode.
Battery maker A123 now acknowledges that a manufacturing glitch at a plant in Michigan caused the problem – which also plagues five other battery car projects. The supplier won’t say who the other customers are, nor will it reveal the precise number of batteries impacted by the glitch but it announced the recall of potentially defective lithium-ion packs will cost A123 about $55 million.
