We have Aug 2018 delivered 100D X. Dublin Service center is closer to us but based on mobile service tech feedback, I've set up an appointment at Berkeley. We have the shudder issue on hard acceleration and Dublin SC pushed back on my service visit last time to address. I even mentioned SB-19-39-001 to Dublin SC via the mobile app. I wanted to ask if people here have had a positive experience with Berkeley SC and do you think they would address the shudder issue ?
