Welcome Moxie. I've spoken
Welcome Moxie. I've spoken with Honda Insight owners that have reported 8 years on their battery modules. I'd anticipate the same from Honda Accord, however, that's just an opinion. Yes.they are pricey. However, if you set aside your savings on fuel costs, I believe the Hybrid will $ pencil out for you. Ask your dealer for full disclosure on the actual cost of the replacement modules and, request a discount on the extended battery warranty in the negotiation of the purchase. In the case of " engine deceleration, and braking, yes, both actions send a charge back to the battery module. It's a great car. enjoy!
