I have had continuos problems with the clutch on my 1998 suabru Outback. Since the car has been purchased I have had the cluch replaced 3 times, and it is now due to go in again. A common problem is "bucking" under load (1st & second). There are countless similar storied available on the internet. Subaru needs to be held accountable for this issue as it affects the majority of Subaru owners.
Subaru Outback (1998) clutch failure. Notorious problem! replaced entire clutch assembly, fly wheel, master cylinder and slave cylinder at my cost!!! dealer would not cover. The clutches on Outbacks are lemons! class action suit from all owners is a real possibility because Subaru has not taken advantage of a "recall". This is a terrible thing (money and time and worry) to see over and over on the internet forums, and experience personally.
Clutch chatter on my 98 Subaru Outback wagon. Problems from day one. Subaru 'fixed' the problem a few time under warranty, but to this day, there is severe chatter in the clutch.
