3,369 miles: I first heard the chirping noise.
9,317 miles: I had Subaru replace the fuel injection pump, the source of the noise.
10,263 miles: The chirping noise came back
10,676 miles: Jim, Subaru Engineer, came down to inspect the car. We drove for 10 mins when the noise reoccurred, proving to him that it was indeed a problem. Jim said “the noise is not detrimental, but annoying” and asked me if I would like to replace it again for a better pump this time. So they replaced the part. Everything was good for about 10 days.
At 11,200 miles the chirping noise came back. FML!
I’m going to call Subaru first thing in the morning tomorrow and ask them if they have a permanent fix for this. Lets hope so.
