If you're searching for a 2023 Nissan Altima 2.5 S Sedan for sale in Escondido, CA, this clean white example at Quantum Auto Sales deserves a serious look.

About This 2023 Nissan Altima 2.5 S

At just over 42,000 miles, this 2023 Altima is barely broken in. Most midsize sedans like the Altima are built to cruise well past 150,000 miles with proper maintenance, meaning this vehicle has the vast majority of its usable life still ahead of it. The crisp white exterior gives it a clean, modern look that holds up well in the Southern California sun, and as a 2023 model year, it still carries the latest generation Altima's refined styling and upgraded interior that Nissan rolled out during its full redesign. Whether you're commuting through downtown Escondido or heading out on the 78 toward the coast, this Altima is ready to handle daily driving with ease.

2023 Nissan Altima Performance and Engine

Under the hood sits Nissan's proven 2.5-liter four-cylinder engine, delivering a well-balanced 188 horsepower and 180 lb-ft of torque. Paired with Nissan's Xtronic CVT automatic transmission, this combination is tuned for smooth, seamless acceleration and excellent fuel efficiency — the Altima 2.5 S is EPA-rated at approximately 28 mpg city and 39 mpg highway, making it one of the more fuel-efficient options in the midsize sedan segment.

The front-wheel-drive setup is the right choice for most California drivers, keeping the weight down and efficiency up. The Xtronic CVT has a reputation for making highway merges and freeway cruising effortless, eliminating the gear-hunting that older automatic transmissions were known for. Around town or on the freeway, the Altima delivers a composed, comfortable driving experience.

Nissan Altima Features and Interior

Technology and Connectivity

The 2.5 S trim gives you a solid foundation of features that make everyday driving more enjoyable. You'll find an 8-inch touchscreen infotainment display with Apple CarPlay and Android Auto compatibility, so connecting your phone and accessing navigation or music is completely seamless. Bluetooth audio and hands-free calling are standard, along with a USB port and available SiriusXM radio.

Comfort and Cabin Quality

Inside, the Altima's cabin is one of the nicer environments in its class. Nissan focused heavily on reducing road and wind noise in this generation, and it shows — the interior feels quieter than many competitors at highway speeds. Cloth seating provides comfortable support for both driver and passengers, and the rear seat offers genuinely generous legroom, making this sedan a practical choice for families and rideshare-style daily use alike. Dual-zone manual climate control keeps everyone comfortable on warm Escondido afternoons.

Safety and Driver Assistance

One of the Altima's biggest selling points — even on the entry-level S trim — is the inclusion of Nissan Safety Shield 360. This comprehensive suite includes automatic emergency braking with pedestrian detection, blind-spot warning, rear cross-traffic alert, lane departure warning, lane keeping assist, and high-beam assist. Getting this level of active safety technology at this price point is a genuine advantage over older used alternatives.

Nissan Altima Reliability and Ownership

The current-generation Nissan Altima has earned a strong reputation for long-term reliability. J.D. Power consistently rates the Altima above average in dependability, and real-world owners frequently report low maintenance costs and minimal issues beyond routine service. The 2.5-liter engine is one of Nissan's most time-tested powerplants — simple, durable, and easy to service at virtually any shop in the country.

Ownership costs on the Altima tend to be reasonable. Routine items like oil changes, brake pads, and tires are competitively priced, and parts availability is excellent given how widely the Altima is sold. If you're looking for a used sedan you can depend on for years without major surprises, the Altima has a well-earned track record to back that confidence up.
