Nissan Rogue Sport Owners Face Engine Destruction From a Simple Fan Failure

A seemingly minor part—the radiator cooling fan—is causing catastrophic engine failures in Nissan Rogue Sport models from 2017 to 2022, according to a new class action lawsuit. The 48-page complaint, filed June 10, 2026, alleges Nissan knowingly sold vehicles with defective fans that can trigger total engine meltdown, leaving drivers stranded in dangerous situations.

The suit claims the problem isn't just inconvenient—it's a safety hazard that can strike without warning.

Here's how it works: The fan is supposed to keep the engine cool, especially in stop-and-go traffic. But the lawsuit says Nissan used faulty materials in manufacturing, so the fan fails and engine temperatures spike immediately. Even one overheating incident can permanently warp cylinder heads, blow gaskets, and cause the car to stall unexpectedly in traffic.

There's another nasty side effect: when the fan dies, the air conditioning system also stops working. That means on a hot summer day or during a heavy rainstorm, drivers and passengers are stuck in a rapidly heating cabin with no way to cool down.

The most troubling part of the case is what Nissan allegedly knew and when. Consumer complaints to the National Highway Traffic Safety Administration date back to at least July 2020—before many of these vehicles were even sold. The suit claims Nissan should have caught the defect during pre-production testing.

Instead, the automaker has not issued a recall and, according to the filing, is replacing broken fans with the same defective parts. At least one owner reported their replacement fan failed again. By allegedly ignoring the root cause and failing to warn buyers, Nissan has left Rogue Sport owners facing thousands of dollars in engine repair costs—or a totaled car.
