The 2014 Nissan Altima comes standard with a 2.5-liter inline-4 engine designated as the QR25DE. This naturally aspirated engine produces 182 horsepower and 180 lb-ft of torque, paired with Nissan’s Xtronic CVT transmission. The QR25DE features dual overhead cams, variable valve timing, and a drive-by-wire throttle system. This engine is known for decent fuel economy, achieving EPA ratings of 27 city/38 highway mpg, but requires regular maintenance including oil changes every 5,000 miles and timing chain inspection around 100,000 miles to ensure longevity.

The 2014 Nissan Altima shares most parts with the 2013-2018 model years, as they belong to the same fifth-generation platform. Engine components from the 2.5L QR25DE are largely interchangeable across these years, including intake manifolds, exhaust systems, and most sensors. Body panels, interior trim, and electrical components are typically compatible within the 2013-2015 range, with some minor changes occurring in 2016. However, always verify part numbers as Nissan made running changes throughout production. CVT transmissions are compatible across 2013-2018, though software calibrations may differ slightly between model years.

The 2.5L QR25DE engine in the 2014 Altima is generally reliable when properly maintained, but has some known weak points. The engine itself can easily reach 200,000+ miles with regular oil changes every 5,000 miles and timing chain maintenance. Common issues include crankshaft position sensor failures around 80,000-100,000 miles and occasional oil consumption after 150,000 miles. The bigger reliability concern is the CVT transmission, which has a poor track record for longevity. To maximize reliability, change CVT fluid every 60,000 miles despite Nissan’s ‘lifetime’ fluid claims, and address any transmission shuddering immediately to prevent complete failure.
