43: 2012 Honda Civic
The 2012 Honda Civic was one of the biggest blunders Honda has made in the last few decades. Critics panned the car for being too small and lacking the quality consumers have come to expect. This prompted Honda to do an emergency redesign the next year (via Car Talk).
There has never been a mess like this at Honda before, and the negative reaction to the Civic was not a good one. The 2012 Civic could have been designed correctly from the gate, but Honda rushed the design into production.
