My car was 20 months old when I bought it. After developing two problems (sunglasses holder peeling off headliner, stereo power button started requiring long hard pushes) I decided it was best to pay for the extended warranty ($2000 CAD for me, lasting till August 2019 or 100,000 km net, whichever comes first), to get peace of mind. $2000 to extend by 4 years is $500/year which isn't too much for me.
My parents have Japanese cars, one 6 years old, one 13 years old, and never bothered with extended warranties. These cars are fully loaded with a lot of tech, but had no issues whatsoever. Japanese reliability is second to none. American reliability has improved a lot over the years (definitely beats European), enough for me to buy and love the Fusion, but it's not quite there yet
I suggest you hold off on buying an extended warranty for the Honda unless it starts developing gremlins near the end of the warranty. Heck, you can buy it long after the original warranty expires, if problems do occur!
