PORTLAND, Ore. -- Daimler Trucks North America announced it was recalling all 110,000 of its 2006-2013 Freightliner, Western Star and Sterling trucks equipped with Detroit Diesel 13-, 15- and 16-liter engines.

Daimler and Detroit will fix a defect the National Highway Traffic Safety Administration said could cause accidents, fuel leaks and fires.

A Daimler spokeswoman said the company reported the possible problem and recall to NHTSA in late February and also sent a Defect Information Notice to the Transportation Safety Board of Canada.

Daimler reported that the engines "pump-to-rail high-pressure fuel line (HPFL) support system is sensitive to assembly torque and may be damaged during service and maintenance procedures."

"There have been no related accidents or injuries," the spokeswoman said. "DTNA is implementing a proactive and voluntary safety campaign."

The trucks involved include 95,853 sold in the United States, 13,479 in Canada and 1,079 that were exported.

"Company officials estimate that less than 1 percent of this vehicle and engine population is affected by the reported defect," according to the spokeswoman.

Detroit Diesel reportedly sold 518 of the engines with the possible defect to other vehicle manufacturing companies, but their identity was not available.

"Inspection of the HPFL support system and replacement, if required, will be performed at authorized Detroit Diesel repair facilities," the Daimler spokeswoman said.

In a letter from NHTSA to Daimler, the safety agency wrote that, "as a result of other repairs [beyond the one described by Daimler], the line supports may loosen, potentially leading to fuel line cracking and a fuel leak."

In a separate paragraph, the letter says: "A fuel leak could create a road hazard, increasing the risk of a crash. Also, a fuel leak in the presence of an ignition source can result in a fire."

NHTSA said Daimler would perform the repairs, where needed, free of charge.
