I have no mods....
Took my car in for the shudder, dealer replicated, called subaru, opened a tech case, was told there is no known fix, returned car with shudder.
Called subaru, and told them about my experience, was told that there is no fix AND that it is normal operating procedure. I replied that the car did not come with shudder, starting happening 3-4 months into mu ownership and had it been normal, why was that fact not disclsoed to me verablly by the delared and why is it not in the manual? Got nothing from them.
Hung -up and retained a lawyer who took the case with absolutely no cost to me. Says it is a slam friggin dunk. Do not accept this from subaru. We did not buy these cars with problems, they should have none. I am fed up, all I want is a car that workfs as it should, flawlessly.
