Even if you can add fuel to your electric car to go for hundreds of miles, they're not fun if you don't have a good soundtrack. Fisker has enacted its second recall on its Karma in less than a month, this time for a software issue that causes the extended-range plug-in hybrid's entertainment and navigation system to malfunction, HybridCars has reported.

The company will stop sales on the Karma until the problem is fixed, Fisker spokesman Roger Ormisher told HybridCars. Neither the company nor the National Highway Traffic Safety Administration has released an official statement on the recall.

The recall represents another setback for closely held Fisker, which pushed back the initial delivery date for the Karma at least four times since the September 2010 deadline company co-founder and chief executive Henrik Fisker first set for the car's debut.

Fisker, which finally started selling the Karma last year, recalled the car in late December because of battery-related safety issues. Specifically, the batteries, which are made by A123 Systems, were found to have potentially caused coolant leaks because of the positioning of the battery cover relative to the car's hose clamps. Fisker and NHTSA officially recalled 239 Karmas that were built between July 1 and November 3 of last year.
