Trim / Codes

The 2009 Nissan Altima Hybrid continued with its 2.5-liter four-cylinder engine paired with an electric motor and lithium-ion battery pack, with only minor trim and equipment updates for the model year. It was sold in limited markets, primarily certain U.S. states. Common service considerations include monitoring hybrid battery health, CVT transmission fluid condition, and the inverter coolant pump, which can fail with age. The regenerative braking system reduces brake pad wear, though calipers and rotors should still be inspected for corrosion.

  2009

  The 2009 Nissan Altima Hybrid pairs a 2.5-liter QR25DE four-cylinder gasoline engine with an electric motor and a continuously variable transmission (CVT), producing a combined output of roughly 198 horsepower. Typical maintenance focuses on CVT fluid changes, spark plug replacement, and the hybrid battery's cooling system, including its intake filter and fan. The 12-volt auxiliary battery and inverter coolant pump also warrant periodic inspection. Regenerative braking generally extends brake pad life, though pads and rotors should still be checked at regular intervals.
