While driving I heard a popping sound and felt the vehicle sway slightly. The vehicle continued to making intermittent banging noises towards the rear passenger side. Upon stopping and investigating I found the rear control arm had failed on the passenger side. I also examined the driver side rear control arm. It was intact but has significant rust, which likely contributed to the passenger side failure, as it also has significant rust. Car has been parked since the incident. I would like to know if the manufacturer/dealer will replace both components free of charge. There was a safety bulletin for the same issue for the 2004-2007 model year of the vehicle (18V-278). A search on the internet found the same failures in my model year for the lower control arms.

The Rear suspension lower control arms were rusted and cracked to the point they were close to breaking into pieces. There were no warning lamps, messages, or symptoms that alerted us to this problem - we happened to look under the car one day and noticed this. This problem was inspected, confirmed, and repaired by a local mechanic and reported to Jeep via their customer service. I am aware that this particular part caused a recall for the 2007 Jeep Liberty (and I'm guessing this is correlated with similar recalls in other manufacturers, e.g. the 2007-2011 Honda CRVs were recalled due to corrosion in the lower frame due to de-icing agents).

The contact owns a 2009 Jeep Liberty. The contact stated while driving 20 MPH, he heard abnormal banging sounds coming from the rear of the vehicle and the vehicle was shuddering violently. The contact veered to the side of the road and exited the vehicle to determine the cause of the failure. The contact noticed that the rear tires had moved forward and were close to the wheel well. The vehicle was towed to an independent mechanic who diagnosed that all four rear control arms were fractured. The contact referenced NHTSA Campaign Number: 18V278000 (Suspension). The dealer and the manufacturer were not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 101,000.

The passenger side rumbles when in motion feels like your driving on a flat tire - but the tires are fine. This cause me to slow down 10 of speed before stopping or the car wombles more.

The body has a noticeable lean to the driver side. The driver side is one inch lower than the passenger side. I had new shocks and struts installed thinking that this would bring the body back to a level position. I also removed all extra gear from the vehicle to eliminate the possibility of extra weight, but the vehicle still has the same amount of lean to the driver side. The measurements are taken on level ground. The measurements are taken from the ground to the wheel well lip through the center line of the wheel. The driver side, front and rear is one inch lower than the passenger side front and rear.

In 2009 I purchased a Jeep Liberty (2009), for the past several months my car was making a strange noise. I've had a diagnostic test done on my vehicle (came back fine), oil changes, engine flushed, filers, transmission checked, all fluids the hole nine yards. Still I could here this noise. In January of 2013, we've had to replace ball bearings, the sun roof jammed, I put in my back tail lights 3times keep blowing out, the door locks started to jam. On March 5, 2013, . I was driving on the freeway and the engine light came on, the car jerked as I continued, then it slowed down and this load noise started coming from under the hood of my truck. I got over into the far right lane and told my wife that the car started to go slow by it self. As I came into a parking lot and wanted to park my truck it jerk again, as I began to park my reverse went out, so I had to park in such away that I did not have to use my reverse to get out of a parking spot. I was taking my wife to a job interview with the secretary of states office ( what are the odds that happening to someone). My wife went to interview we took the service drive and some back streets to get to our home. I got up the next day to take it to the shop and the hold transmission had gone out and all the fluids were in our driveway. I don't have 100,000 miles on the truck nor is this truck five or ten years old. Why are all these things happening, this truck just turn4yrs old? we brought this truck 03/03/2009. Someone please tell me how your transmission just die and we've never had an accident, just the usual maintenance on the truck. The dealership said I did not purchase the powertrain warranty (100,000ml/10yrs.) to repair, will cost me $5,000 to get a new transmission. My job put us on 30hrs a week.
