The 2012 Nissan Altima is a midsize sedan (also available as a coupe) that balances comfortable daily driving with good fuel economy and a relatively sporty feel for its class. It’s ideal for commuters, small families, and anyone who wants a roomy cabin and easy-to-find parts without stepping up to a larger full-size sedan. The 2012 model sits in the fourth-generation Altima run (2007–2012), making it one of the later, more refined versions before the full redesign for 2013. In the used-car market, it’s often cross-shopped against the Honda Accord and Toyota Camry for value, ride comfort, and feature content.

1) Engine choices: Most 2012 Altimas use a 2.5-liter inline-4 (around 175 hp), while the optional 3.5-liter V6 delivers stronger acceleration (around 270 hp). Both engines are known for smooth power delivery when properly maintained. 2) Transmission availability: Many 2012 Altimas came with Nissan’s Xtronic CVT automatic, while some trims/configurations offered a 6-speed manual (more common with the 2.5 and on certain models). Shoppers often seek the manual for simplicity, but CVT-equipped cars can be dependable with careful upkeep. 3) Fuel economy: The 2.5-liter models are known for strong real-world MPG for a midsize sedan, making the Altima a popular choice for high-mileage commuting. 4) Cabin space and comfort: A spacious front row, supportive seating, and a trunk that works well for groceries, luggage, or strollers make it an easy everyday car. 5) Common comfort/tech features: Depending on trim, you may find push-button start, Bluetooth hands-free calling, steering-wheel audio controls, and available Bose audio/navigation on higher trims.

Shoppers researching 2012 Nissan Altima problems and 2012 Nissan Altima reliability should know this is a generally solid midsize sedan, but it has a few repeat trouble spots that show up in owner complaints. 1) CVT transmission shudder, slipping, or failure: The most discussed 2012 Nissan Altima common issues involve the CVT. Symptoms can include shuddering on acceleration, RPM flare, delayed engagement, or overheating behavior, sometimes appearing around 80,000–120,000 miles (earlier in harsh driving/heat). Repairs can be expensive if the transmission requires replacement, so service history matters. 2) Excess oil consumption on some 2.5L engines: Some owners report the 2.5-liter using more oil than expected as mileage climbs, often noticed beyond 90,000–120,000 miles. If oil level isn’t checked regularly, low oil can accelerate engine wear and trigger warning lights. 3) Steering lock / push-button start no-start (intermittent): Some vehicles experience an intermittent no-crank/no-start condition tied to the steering lock module or related starting authorization components. It may present as the car not recognizing the key fob or failing to crank, sometimes without much warning. 4) Suspension and brake wear items: Front control arm bushings, struts, wheel bearings, and brakes can wear in the 70,000–120,000 mile range depending on roads and driving style. Clunks over bumps, steering vibration, or uneven tire wear are common clues.
