THE INVESTIGATION: In July, the National Highway Traffic Safety Administration began investigating the 2012 Jeep Grand Cherokee after getting reports of fluid leaks and engine fires.
THE PROBLEM: The safety agency traced the problem to a defective power steering fluid hose that could come loose and leak fluid.
THE RESULTS: The agency closed its investigation without issuing a recall, saying that the SUVs don't present an unreasonable safety risk. The agency says none of the leaks caused crashes or fires, and it's unlikely that leaking fluid would reach any ignition sources. All the problems occurred within seven months of when the SUVs were sold, and all were fixed under warranty by Chrysler, which makes Jeeps.
