When traveling down the road you can hear a very audible squeak and clunk coming from the passenger rear of the vehicle. After arriving home I pulled into the garage to determine the location of the noise, I placed a jack under the rear door on the pinch weld and raise the wheel off the ground and removed the tire. Upon further inspection I noticed the the right rear subframe which connects to the rear frame of the vehicle was completely rusted from top to bottom with only a fraction of the metal remaining around the bushing. The driver side rear subframe connection is also rusted from top to bottom, the subframe on the driver is contacting about 90 percent of the bushing the passenger side of the subframe is contacting about 10 percent of the bushing. The rust on the rest of the vehicle frame and front subframe is slightly rusted. My vehicle is 2009 Nissan Murano with 160,000 miles. This is my main vehicle for transportation for my kids and family. This issue has been known to Nissan as many people have notified Nissan of this manufacturing issue. This had been an issue on the 2006 Nissan altima in which Nissan issued a recall for the rear subframe rusting which is the same issue this and many other Nissan Murano owners are having but Nissan has not yet issued a recall.
