Koni FSD Failures

[mdreuben]

My '05 S has now suffered it's second failure with Koni FSD's. The right rear has died and the car clunks horribly. The first failure came at 9 months (also the right rear) and the replacement has lasted less than three.

Koni replaced the first set (although I had to pay to have them installed) and I'm waiting to hear back about this second failure.

Should I give up on them or try something new? My driving is primarily city and I am looking for something to soften the ride somewhat.

Thanks!

Thanks for the info. The first I've heard of failures. Please keep us posted... I've had mine on for a few months and absolutely love 'em.

Never heard back from Koni as to the source of the failure. I just assumed that every once in a while things break, but now that I've had two bad units....

yeh,im thinkin' of runnin' a set on my car but dont noe yet??? doesnt sound to good...

Problem solved - mounting bolts at the top of the shock had come loose - just enough to bounce around.

My driver's side front is at Koni NA for evaluation; it was making knocking noise and damping had deteriorated. The strut nut was tight as well as all suspension and chassis fasteners; no fluid evacuation to indicate failure. The "knock" could be repeated off the vehicle.

I have my FSD's for about a month and so far i absolutely love them eventhough i think that the car has lost a bit of it's sharpness at extreme conditions..
But since my wife is pregnant at her 7th month i don't care that much for this..
It really does a magnificent job and i'm happy with them!

Hope they won't break down though..

Just as another data point, I'm very happy FSD customer with no problems after a year and about 16000 miles.

I heard there's a problem inside the shock when you lower the car more than 30mm?
Is yours lowered at all?
