GM's mild hybrid battery problem?

Malibu hybrid: Plagued by battery problems?

This morning AutoWeek ran a story regarding a recall of GM's mild hybrid vehicles, such as the Chevy Malibu hybrid. Turns out the Cobasys NiMH batteries used in the hybrid cars had an internal leak which caused the hybrid powertrain to shut down. Reps from both GM and Cobasys stated the problem had been resolved.

Even though Chevron owns many NiMH battery patents, I guess they don't know as much about batteries as they think they do!
