20: Honda Passport
Again, here comes Honda with the rebadging. The Honda Passport was originally nothing more than an Isuzu Rodeo. Considering Honda has built a reputation around reliability, it was odd to observe the automaker do this. There was nothing remotely appealing about the Passport to separate it from the Isuzu sibling (via Motor Trend).
In fact, the Passport had to be recalled due to frame rust, and it cost Honda millions to do the repairs. The debacle caused Honda to shelf the Passport nameplate for two decades before it was revived much later on. Just goes to show you that even the best Japanese automakers in the world can make a mistake.
