How long would you like them to warranty it? No manufacturer warranty's their car after 100,000 miles. GM has already stated that they expect a 20% degradation of the battery after 100,000 miles. It's a battery, it degrades over time.Quote from pspr:
No dealer will probably take it in a few years because it has that big toxic battery. GM only warrants the battery for 8 years or 100k miles and the range is probably down 10-30% by then.
