When one thinks of Japanese automobiles, the word “reliability” often comes to mind. However, even in the land of the rising sun, there have been instances of vehicles that fell short of the reliability standards expected from Japanese manufacturers. Which Japanese car is the least reliable of them all though?
Our lead image is that of the Mazda RX-8, a car that is synonymous with the words ‘apex seals’ for good reason. Unlike most engines that seem to go almost indefinitely so long as they’re well maintained, the RX-8’s rotary engine requires new apex seals almost like clockwork. We’re talking about replacing them well before most engines hit 150,000 miles.
If we want to focus on transmission issues the list gets a lot longer a lot faster than if we focus primarily on engines. The JATCO continuously variable transmission in a plethora of Nissan vehicle seems to have serious design flaws. In fact, Nissan settled a lawsuit to the tune of $277 million to resolve defective transmission claims.

The settlement included the Rogue, the Pathfinder, and the Infiniti QX60, so it was a widespread issue. It’s not a new problem either. Nissan’s original Murano had similar issues with its CVT. Instead of having the option to rebuild a slipping or failing CVT, customers are often stuck with simply replacing it altogether.
In recent months, it’s become clear that the Toyota GR86 and Subaru BRZ have some oiling issues that may cause catastrophic engine failure. We’re still in the early stages of that potential problem but online forums are buzzing about it worldwide.
Let’s point out that the only cars we’ll count are those from Japanese brands with Japanese drivetrains – so no A90 Supra there. That’s the only rule though so by all means, have at it otherwise. Tell us, what’s the least reliable Japanese car in history. Be sure to vote for your favorites too.
