The vehicle went in for an inspection because there was a clunking noise from the passenger rear of the car. It turns out that the rear subframe and right rear sway bar has rusted completely off. The amount of rust by the technician has been found to be exorbitant in comparison to the amount of miles it was driven. The tech suggested that the car was submerged, but there was no record of it being so. I am the third owner of the car. I would like to file a complaint, for there seems to be a lot of this issue online, from Ford Focuses from 2000 to 2005.
