WASHINGTON, D.C. --- Kia is recalling 6,680 MY 2008-2009 Rondo LX and EX vehicles equipped with a 2.4-liter engine, the National Highway Transportation Safety Administration said.

The fuel pump may not operate properly, resulting in not enough fuel getting to the engine. Poor engine starting, engine hesitation and other impairment may result, the NHTSA said.

Dealers will replace the fuel pump sub-assembly with an improved part. The recall is expected to begin this month.

Owners may contact Kia at (800) 333-4542.
