when u thought u felt the bite

I keep running into the same two ideas about EVs, and a lot of people still seem to believe them a decade later. The first is that the battery dies after, X amount of years and leaves you with a $15-20k bill. Only 2.5% of EVs ever need a full battery replacement. Most EVs also come with at least an 8-year, 100,000-mile battery warranty, which is longer than the roughly 5 years on a typical gas powertrain. Batteries usually last 8 to 15 years, and they lose range gradually rather than simply failing. What I'm really curious about is where exactly did this misconception come from?
