GM warns of potential battery degradation of up to 40% for Chevy Bolt EV
- DrScump 10y agoAn important qualifier is not consistent with the tone of the title: ... within 8 years or 100,000 miles 20-40% as opposed to an expected 10-20%. <But that’s not what GM says you should expect. It’s what is covered by the warranty. For comparison, Tesla warns that it does not cover battery degradation from “battery usage” under its warranty...> So, the content seems to counter to the clickbaity, negative-toned title.
- greglindahl 10y agoTesla's battery warranty activates at 70% up to 8 years/infinite miles. Needless to say, the expectation is that the overwhelming majority of cars won't see that much battery loss, and in fact the observed average is 10% loss at 150,000 miles. (This number, and this theory, are both from the article; I'm adding in the 70% number based on what Tesla has been telling consumers who ask about the warranty.) GM is probably playing out the same strategy: 40% is a loss rate that almost no Bolt owners will see.
