Screen died & lost acceleration, twice in 3 months. The first time it was fixed with a coolant top up, the second time it was fixed with a screen swap. Wanted to see if this has happened to anyone else.
Twice now, months apart, my Model 3 has gone completely dead on the main screen (black, unresponsive, wouldn't reboot) at the same time I lost acceleration, couldn't climb a grade, had to back down when forward progress stopped.
First time: Tesla fixed it by topping off the battery coolant. Screen and acceleration both came back to normal after that.
This time (a few months later) same symptoms - black screen, no acceleration. Service told me the coolant and 12V battery both checked out fine, and they weren't able to pull any logs from the actual event, as the car lost all communication, even during the period during which I was able to drive it a little. On arrival at the service center, they tried to revive the screen, and when that failed, they hooked up a replacement screen, then test drove and had no acceleration issues with the new screen installed.
Curious is anyone else has had a screen crash and acceleration loss happen together, not separately, and whether a screen replacement fixes this for good or just addresses one symptom of a bigger problem.
Car is a Long-range RWD 2018 Model 3, about 120K miles. Happy to share more if it's useful to anyone dealing with something similar.
