While not technically a bad car, the Accord Crosstour looked like a monstrosity - essentially an SUV stretched out and flattened down with some unwelcome Prius elements at the back.
Automakers still struggle to fit 6-7 people comfortably over three rows, so why Honda thought it could do so with just two rows is anyone's guess. The FR-V was bulky and cramped.
The CR-Z could have been great. It was an eco-friendly little hybrid, but it was underpowered and didn't handle as well as its looks suggested. It also wasn't all that efficient.
Honda made the odd choice to put the lever that adjusted the passenger seat reclining function on the driver's side rather than by the door, so people called it the "Pervert Lever."
While it could have been a proper rival to the acclaimed Mazda Miata, the Civic Del Sol suffered from reliability issues and poor build quality not to mention electrical faults.
Honda partnered with Austin Rover Group to try to break into the UK market, but it used the blunt instrument that is the Concerto instead of a precision instrument like the Civic.
While it was eventually redeemed, the Odyssey was a complete failure in the US when it launched. It was far too small to work in the market and it looked like a bloated Accord.
The 2nd-gen Insight was actually a great car with amazing fuel economy, but it suffered a horrible fate at the hands of the Toyota Prius's superior marketing and scorn by the liberal elite.
