2 walk-away risks, 6 serious faults documented for this generation, weighted by severity and repair cost. Biggest factor: qr25de pre-cat breakup and oil consumption. Score methodology.
The 2005-2008 Nissan Altima is worth buying only when the expensive known faults are checked before price is agreed. The main risks are QR25DE pre-cat breakup and oil consumption, QR25DE head-gasket overheating, Early CVT hesitation or flare, corrosion or water intrusion, and trim-specific electrical faults. The safest example has closed recalls, boring service history, no hot drivetrain symptoms, dry carpets, dry underbody and a scan that supports the seller story.

- Simpler drivetrain/trim with documented fluid and oil service.
- Dry low-rust car with matching tyres and clean scan data.
Inspect hard
- Automatic/CVT cars for hot shift quality and stored codes.
- Turbo, diesel or direct-injection variants for oil, timing and emissions history.
- High-spec cars for roof, camera, infotainment and body-module faults.
Avoid

Next checks
Before you contact the seller
Check the car's history first. Then bring the right tools if it still looks worth viewing.
Primary next step
Check history, title, and recall status
The faults above matter more if the car also has accident history, finance flags, missing service records, or open safety recalls.

Engines and trims
Which Nissan Altima should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.

BUY WITH OIL/CVT PROOF
The volume engine is cheap only when oil and gearbox history are clean.

STRONG BUT HARDER ON DRIVETRAIN
More power means more mount, clutch and CVT load.
