2012 Fisker Karma

Battery maker A123 has announced that batteries it supplied to Fisker Automotive for its Karma range-extended luxury sedan might have "misaligned" hose clamps for the cooling system, which could cause coolant to leak. Unabated, A123 admits the leak could cause an electrical short-circuit.

According to Bloomberg-BusinessWeek, the company has a fix for the issue, and luckily the issue was discovered when there are no more than 50 Karmas needing the repair. A123 provides batteries to several other OEMs, but only Fisker's batch appears to suffer from the cooling issue.
