Is the O2 sensor covered under the Nissan warranty?

Over the past few months, I’ve noticed a rough sound when my car is idling, and I think it may be the oxygen sensor. I took it to my mechanic, and he said the same thing. Is the sensor covered under the Nissan basic warranty?

You’re right—that does sound like a faulty oxygen sensor. Luckily, the O2 sensor is covered under the
Nissan
Emissions Warranty for a set duration.
A faulty oxygen sensor could cause your vehicle to run irregularly or sound rough during idling. It can also interfere with your engine’s timing, combustion intervals, and other critical functions, and you may even notice stalling or slow acceleration.
So, let’s get your Nissan fixed up! Here are the details you need to know about the warranties that may apply to your car’s issue.
Federal Vehicle Emissions Control Limited Warranties:
  • Performance—2 years/24,000 miles
  • Defect—3 years/36,000 miles
  • Long-term defect—8 years/80,000 miles
California Vehicle Emission Control Warranties:
  • Performance—3 years/50,000 miles
  • Defect—3 years/50,000 miles
  • Long-term defect—7 years/70,000 miles
That said, warranty coverage does vary by model, so ensure you check your specific warranty for more information.
