1.at about 12000 miles, the right rear of vehicle began to make a knocking noise while going over bumps, braking or accelerating is more evident at low speeds but is still present at higher velocities. 2.the failure is currently still existent, the right rear of vehicle has about 1/4 in loose play before the rear strut binds. This affects handling of vehicle during turns or emergency maneuvers as the suspension is not well controlled by strut binding. When coming to a stop, one can feel the right rear corner of vehicle settle and hear a knocking sound. This issue twice sent the vehicle out of control while turning to the left on bumpy roads and fortunately no one was injured and no damage was done. This defect has been talked about at great length in various Subaru Impreza sti forums and is referred to as the"rear strut clunk" and it can affects both sides of vehicle. Model year 2004 and 2005 Subaru Impreza sti are involved in this. It is possible that my 2006 and 2007 are as well but I haven't checked. 3.the dealer has replaced the upper strut mount a few times to no avail. The defective parts are still on the vehicle.

Rear struts (and possibly front) are making a clunking noise when car is driven at slow speeds. The noise is quite apparent and would not be items inside the trunk and/ or car.

Rear struts stick and will not rebound after a compression stroke. Causes rear to sag and handling feels very loose. Very noisy. Subaru of America know about the problem, which is either a design or manufacture flaw, and does nothing to issue a recall. There are hundred if not thousand of documented cased on the internet of this problem. I have had three rear struts replaced, so far...and once car is out of warranty, repair costs are $500 per strut labor included to replace.
