WASHINGTON — The National Highway Traffic Safety Administration is reviewing a request for a formal probe into 517,945 2003-'05 Ford Crown Victoria and Mercury Grand Marquis sedans for lighting problems.
The problem involves an alleged failure of the front lighting control module, resulting in a loss of headlights and/or all exterior lighting while driving, according to NHTSA.
The North Carolina Consumers Council requested the investigation.
Federal safety regulators looked into the issue in 2008 without demanding a recall.
"The petitioner notes that Ford recently extended the subject vehicle warranty for this part to 15 years or 250,000 miles, states that service replacement parts were not readily available for warranty repairs at the time of the petition submission and requests that a new defect investigation be opened," NHTSA said in its summary of the action.
NHTSA said it has opened a defect petition to evaluate the issue and make a "grant or deny decision."
Ford spokeswoman Kelli Felker told Edmunds the automaker will cooperate with the probe.
Edmunds says: Owners of these vehicles will have to wait for federal safety regulators to finish their work before taking any action. But if you have an immediate concern, it's best to contact your dealer.
