A recent study by Recurrent Auto shows that EV battery replacements due to failure are quite rare, with only about 1.5% of EVs needing replacements, most of which occur under warranty. It was noted that higher replacement rates in models like the Chevrolet Bolt EV and Hyundai Kona Electric were due to recalls, while the overall rate for other models remains very low. Even older models like the Nissan Leaf, which had early issues, now show improved performance with few replacements needed (Autoblog) (GreenCars).

The study also highlights that Tesla’s Model S and Model 3 demonstrate strong battery longevity, with fewer than 5% and 1% of these vehicles, respectively, requiring replacements. This data alleviates concerns about long-term battery degradation, indicating that EV batteries generally maintain their capacity well over time, supported by robust warranties from manufacturers (Autoblog) (GreenCars).
