The final cut of TMC Podcast #29 is available now with topics time-stamped. We discussed the Tesla Cybertruck's expected 1 MW Ultra-Fast Charging capability, the Tesla Semi Delivery Event, the coming Model 3 refresh (project "Highland"), and more. You can watch it now on YouTube.
Good news and bad news. The bad news is that this may be a hardware issue. The good news is that the sort of artifact you're seeing usually is just the connector between the hardware rendering the image and the actual display (think of it as the cable between your computer and monitor, or on a laptop the cable in the hinge connecting the screen to the rest of the hardware). It's possible the connector is simply loose or failing, and with any luck Tesla can just reattach it for you or acquire a new connector cable.
Unfortunately, this $4 connector may only come as part of the $1,500 "screen assembly". You'll want to talk to Tesla about this.
Hey @Tezla1 All M3's come with 4Y comprehensive warranty or 50K miles, whichever comes 1st. You also get 8Y and 120K miles warranty for the powertrain (battery and motors) since you have the AWD model with dual motors. So unless you've driven more than 50K miles, you're all set.
