As it turns out, Fisker’s existing voluntary recall of 239 Karma sedans in December 2011 did not cover all the affected models.

Today, the California-based automaker issued a supplementary recall that adds to the list a further 19 cars manufactured from September 22, 2011, through January 20, 2012, ten of which have already been delivered to customers, according to Fisker.

“Within the high-voltage battery, cooling hose clamps may have been positioned incorrectly during the battery assembly process,” the company said in a filing to the National Highway Traffic Safety Administration (NHTSA).

“When positioned incorrectly, the battery compartment cover could interfere with the hose clamps and cause a coolant leak inside the high-voltage battery. If coolant enters the battery compartment, an electrical short could occur, possibly resulting in a fire,” Fisker added.

Fisker will fix the problem by replacing the high-voltage battery pack free of charge.

The automaker noted that even though no safety incident has been reported in regards to this issue, it has notified and instructed Karma owners not to charge or drive their vehicles due to the potential fire risk.

“Owners will be advised to contact an authorized Fisker dealer who will arrange transporting the vehicle directly to their repair facility,” said Fisker.
