I purchased a Nissan Qashqai on 01/04/2007. I had a diesel leak on the injectors within 4 months, then, after 12months, new shockers on rear then another set of shockers at 20 months. I don't think it's the shockers at all. I think there is a problem with the rear void bushes. Nissan has checked this and say there is no problem found but there is a knocking noise from the rear. The whole rear subframe floats by this. I mean you can move the wheels and the body of the car doesn't move. Has anybody else reported this fault?
