DETROIT -- U.S. safety regulators have cleared the 2012 JeepGrand Cherokee after an investigation into possible engine fires.

TheNational Highway Traffic Safety Administration began checking 107,000of the SUVs in July after getting complaints about power steering hosescoming loose and leaking fluid onto the engine.

The agency found24 cases of loose hoses. The problem was traced to a defect inside thehose that was fixed at the factory shortly after the SUVs went intoproduction. The agency says none of the leaks caused crashes or fires,and it's unlikely that leaking fluid would reach any ignition sources.

The agency says the problem hasn't caused an unreasonable safety risk. It will continue to monitor the SUVs.

SUVs with the problem were fixed under warranty by Chrysler, which makes Jeeps.

All of the problems happened in Grand Cherokees made between Nov. 22, 2011 and Dec. 23, 2011.

"Therehave been no reports of loss of steering control, crashes or injuriesas a result of this condition," NHTSA said in documents posted on itswebsite Tuesday. "There is no indication of loss of motive power orunreasonable safety risk associated with the alleged defect."

NHTSAsaid that changes by the company that makes the hoses have eliminatedthe likelihood that the hoses will come loose. Still, the agency said itwill continue to monitor the vehicles.

The investigation found five reports of engine fires, but NHTSA determined that all were caused by other factors.
