The car computer in my 2021 Tesla Model Y bricked 24 hours after updating to v14 Lite. 20% of the the people who responded to @wholemars’ poll so far have experienced their car computer failing. I highly recommend not installing FSD v14 Lite on your HW3 @Tesla.

So far i’ve seen 0 compelling evidence that V14 Lite causes overheating. I’m not saying it’s impossible, but seems to be speculation that everyone is treating as fact at this point. The computers are liquid cooled. I rode in @BLKMDL3’s car the night the first V14 Lite build came out. As far as I know the computer hasn’t suddenly exploded. @koby_pierce drove from Kentucky to key west in florida to the top of Alaska on V14 Lite and his computer was fine. If this was a common issue, he would have been toast early on. As far as I can tell this is not a widespread issue, and I have heard of people getting computers replaced long before V14 Lite. It feels to me like a more likely explanation is just that some of these cars are old and there’s a massive heatwave across the US and the world right now. It’s possible that a coolant leak or something might cause a problem. If there is an issue, im sure Tesla will fix it and replace peoples computers. But so far ive seen zero compelling evidence that this is caused by FSD 14 Lite rather than other factors. V14 Lite users, what do you think? Did this update break your computer?
