U.S. safety regulators have cleared the 2012 Jeep Grand Cherokee after an investigation into possible engine fires.

The National Highway Traffic Safety Administration began checking 107,000 of the SUVs last July after getting complaints about power steering hoses that came loose and leaked fluid onto the engine.

The agency found 24 cases of loose hoses. The problem was traced to a defect inside the hose. NHTSA 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. The defects, according to NHTSA, were fixed at the factory shortly after the SUVs went into production. NHTSA says it will continue to monitor the SUVs.

SUVs with the problem were fixed under warranty by Chrysler, the manufacturer of Jeeps.
