I'm going to post something I wrote in another thread.
Check the warranty booklet that came with your car. If your car's designation is AT-PZEV, I'm pretty sure you have the same warranty as me (very likely since you said you bought your car in MA, a PZEV state). If so, you have a factory warranty that covers the IMA system for 15 years/150,000 miles (the battery itself is warrantied for 10 years/150,000 miles). This is a Honda warranty that doesn't come from the dealership or a third party. More over, it doesn't cost anything.
With that said, the AT-PZEV warranty is not a bumper to bumper warranty. It covers major emissions related parts, the most important being the IMA components.
Here's a link to the original warranty page on the Honda Owner's Link website. You can check what warranty comes with your car.

Because of this comprehensive factory warranty, I didn't see the need for any additional warranty.
Hope this helps.
