Nissan vehicles pass California smog reliably in most cases, but CVT transmission-related OBD codes on Altima, Rogue, and Murano models are the most common source of unexpected readiness monitor failures.
- 2013-2018 Altima with CVT: CVT fault codes P17F0 and P17F1 affect transmission control module communication with OBD — can cause 'not ready' status or active fault state
- 2007-2012 Murano CVT: similar CVT code patterns; address CVT health before testing
- Rogue 2.5L (2014-2020): generally reliable, but EVAP monitor is slow to set on some model years after battery work — drive 100+ miles before testing
- Frontier and Titan V8: strong compliance history; elevated HC readings on high-mileage examples warrant O2 sensor check before testing
- Nissan Leaf (BEV): fully exempt from emissions testing; no smog inspection required
- Pathfinder 3.5L VQ35: catalytic converter degradation after 120,000+ miles is the primary watch point
