How’s the Model 3’s build quality and reliability now? I used to follow it more closely but gave up when it seemed apparent that they weren’t taking those things seriously more than a year into production. Much as I’d love to go electric, if I were in the market for a new car right now, I wouldn’t cross-shop a car famous for its longevity with a Model 3.

AFAIK Chinese-made Teslas are fine. EVs have pretty good longevity. The powertrain has fewer moving parts and isn’t exposed to air and vibrations. Tesla’s batteries generally age well, with 1-2% capacity loss per year. It’s gradual decline, they don’t just die. Also I’m hopeful that in 10-15 years when it’s time to replace the battery, there will be cheap upgrade options already available. This has happened with Leaf – it launched with a 24kWh pack, and a decade later you can get 40kWh for the same price, and there’s 64kWh option.

  It's more accurate to plot battery degradation as a function of miles, not time. And from what I've seen, 1% per 10,000 miles seems to be a common measure. So after 150,000 miles, you might lose ~15%. I dunno about you, but I wouldn't replace the battery just from 15% degradation. Even if I was, I'd be more likely to just buy a new car at that point.

    at what point in time (or after how many miles) does the battery must be replaced? does the weather the car is driven in matter on battery life?

      That's an individual judgement call. If you don't go on road trips, then even 50% degradation (representing over 500,000 miles of usage, an absolutely absurd number for someone that doesn't do road trips!) still leaves you with a usable car. I don't know how weather affects battery life. I know that very cold weather reduces charging speeds, but I don't know if it reduces the life. The battery is liquid-cooled, so temperatures are still controlled in hot climates. Generally, replacing the battery is not something any Tesla owner needs to worry about. Outside of failures that are typically discovered within the first year or 10,000 miles (and therefore covered by warranty), the battery will last FAR longer than any typical car. How many cars are driven past 300,000 miles?
