NHTSA complaint #10236155, filed 2008-07, 59,000 miles“I have a Jeep Liberty renegade 4x4 with only 38,000 miles on it. I was driving on the quickway (hwy 17 in middletown, ny) when my car dropped dead in the road with no indications of anything wrong with it. It had gas in it, it's fluids were all changed, etc. I found out later that the spring broke causing the rocker arm to drop out therefore causing major damage to my vehicle.
