(July 26, 2010) Volvo SUVs are being investigated by U.S. safety regulators for intermittent electronics defects in components such as headlights and turn signals, which may raise the risk of a crash, Bloomberg News reported today.

Volvo XC90s for model years 2004 and 2005 have been the subject of 21 complaints about intermittent malfunctions of the components in city driving and at highway speeds, the National Highway Traffic Safety Administration said today on its Web site.

The defect isn't linked to crashes or injuries, NHTSA said. The model years include about 93,487 vehicles, according to the agency. When the unit controlling the electronic parts was replaced, the flaws were corrected, NHTSA said, citing the complainants.

“We will provide all the information that NHTSA asks and we'll work closely with the agency to make sure the issue is resolved,” said James Hope, a U.S.-based Volvo spokesman.

Volvo is being bought by Zhejiang Geely Holding Group Co. from Ford Motor Co. for $1.8 billion. Ford expects the sale to be completed this quarter.
