2025 Consumer Reports list of least reliable Japanese models

Consumer Reports names the least reliable Japanese models for 2025, including Honda Prologue, Infiniti QX80, Mazda CX-90/CX-70, and Toyota Tacoma. Learn why.

Consumer Reports has published a list of Japanese models with the weakest predicted reliability for 2025. Even though Subaru, Lexus, Toyota, Honda, Acura, and Mazda occupy the top six places in the overall brand rankings, some of their models underperformed.

The Honda Prologue and Infiniti QX80 were among the least reliable, tying for fourth from the bottom. The electric Prologue, built on the Chevrolet Blazer EV platform, turned out far less dependable than expected. The Infiniti QX80’s troubles were linked to its latest version and technology faults following the refresh. When lineups are updated, early production issues are common, and both examples show that.

Next came the Mazda CX-90 and CX-70 with the same score. Despite the brand’s strong standing, both fell behind rivals on reliability—proof that brand strength does not automatically transfer to every model.

A genuine surprise was the Toyota Tacoma, one of the most popular pickups in the United States. The new generation proved less reliable than the Ford Ranger and Jeep Gladiator, a result affected by several recalls. Popular models can stumble when early fixes pile up.

At the bottom of the list were the Mazda CX-90 Plug-in Hybrid and CX-70 Plug-in Hybrid. Their plug-in versions were named the most problematic among Japanese vehicles.
