NHTSA Complaint #11455890 — 2016 TESLA MODEL S

I took my car in for the tesla video card replacement voluntary recall. After the "repair," my display screen acts erratically and visually becomes distractive. So far the service centers are trying to UPSELL me a new system to replace the current "repaired" system for $1500. I have had no luck with them taking responsibility for this issue. The big screen flickers the navigation screen and also distorts the items on the screen. As of yet, they keep saying this is normal function/behavior and all I have been asking is to have the screen operate as it is intended. (which it was prior to the chip update). Also, I believe the issue is also affecting the audio in the car.....at times the sound has become distorted and think that sound is absent from the turn signals. I know the audio system must have been impacted by their "repair" because initially the system sounded twice as clear than before the chip upgrade.
