Carmakers don't typically ask prospective customers how long the warranty should be on their new car. That decision is usually made based on how much the manufacturer thinks longer warranty coverage will cost and what its competitors might be doing. However, as we enter the era of electrification we are dealing with a major new factor: the battery packs.

Nissan has priced its upcoming Leaf EV very aggressively, hoping to undercut the still-unpriced Chevrolet Volt. General Motors, on the other hand, is still being cagey about the Volt price but came out swinging with an eight-year/100,000-mile warranty for the battery. Nissan quickly followed that up with a survey sent out to people who have signed up for the $99 Leaf reservation list to get their thoughts on battery warranties. So, how long do you think the battery warranty should be? Thanks to Chris for the tip!

How long should EV battery warranties be?
10 years / 150,000 miles 1 (20.0%)
8 years / 100,000 miles 1 (20.0%)
5 years / 60,000 miles 1 (20.0%)
3 years / 36,000 miles 1 (20.0%)
battery warranty doesn't matter 1 (20.0%)
