Nissan Altima (L33) Buyer's Guide
CVT Reliability and Oil Consumption
The L33 Altima (2013-2018) was Nissan's volume-leading midsize sedan, known for class-leading fuel economy and a spacious interior. But its reputation is defined by the CVT transmission — the single biggest factor in used Altima pricing.
Powertrain: The 2.5L QR25DE four-cylinder makes 182 hp and pairs exclusively with Nissan's CVT. The 3.5L VQ35DE V6 (3.5 SL) makes 270 hp and is considerably more reliable. The 2016 refresh brought updated styling and improved CVT calibration.
What to look for: CVT condition is everything. Ask for CVT fluid change records — every 30,000 miles is ideal. The 2013-2015 models had the highest CVT failure rates. Post-2016 CVTs are improved but still need diligent maintenance. The 2.5L had oil consumption issues through 2015. A V6 Altima with a well-maintained CVT is the hidden gem of this generation.

Frequently asked questions
Is the Altima CVT really that bad?
Early L33 CVTs (2013-2015) had a higher-than-acceptable failure rate. Post-2016 CVTs improved significantly. The key is maintenance — fluid changes every 30,000 miles make a huge difference.
Should I buy the 2.5 or 3.5 Altima?
The 3.5 V6 is more reliable (no CVT issues unique to it) and more enjoyable. But it's rare and gets 22 MPG combined vs the 2.5's 31 MPG. For most buyers, a well-maintained 2.5 is the practical choice.
What's a good price for a used L33 Altima?
The Altima depreciates faster than Accord or Camry — a $12,000-16,000 L33 with 60k-80k miles is a solid value. Budget $1,000-2,000 for CVT fluid changes over ownership.
