what problems does the 2012 altima have?

Question

Accepted Answer

The 2012 Nissan Altima is actually one of the better years of the fourth generation (2007-2012), but there are still some issues worth knowing about—especially at 128,000 miles.

**The Big One: CVT Transmission**

This is the primary concern with this generation. The Xtronic CVT can fail, and when it does, replacement runs **$3,500+**. The good news? The 2010-2012 models were the most reliable of this generation with fewer CVT issues than the 2007-2009 models. That said, at your mileage, listen carefully during a test drive for any whining, humming, or jerking during acceleration. If you notice those symptoms, walk away—transmission repairs are costly.

**Other Common Issues to Watch For:**

• **Oil cooler gasket leaks** – Oil drips on the passenger side of the engine. The gasket is cheap (~$20), but it's labor-intensive to access (1.5-2 hours). Very common on both 4-cylinder and V6 models.

• **Catalytic converter failure** – Check Engine light (P0420), reduced power, possible sulfur/egg smell. Expensive repair when it happens.

• **Ignition coils** – Misfiring, shaking, CEL (codes P0300-P0306). Coils are inexpensive and easy to replace on the 4-cylinder.

• **Crankshaft/camshaft position sensors** – Can cause stalling or no-start. Nissan has a recall—check if this car qualifies.

• **Coolant leaks** – Radiator, plastic filler neck, or hoses can leak at higher mileage. Keep an eye on coolant levels.

• **Wheel bearings** – Humming noise at highway speeds that gets louder when changing lanes (~$280-400 per bearing).

• **Brake master cylinder** – Can leak fluid; look for the brake warning light. Nissan issued a service campaign.

• **Electronic Steering Column Lock (ESCL)** – Check for recall PC516.

The 2.5L QR25DE engine itself is solid and can last well beyond 200k miles with maintenance. A friend at a Nissan dealership mentioned regular CVT fluid changes (every 50k miles with Nissan fluid) helped his Altima hit 175k+ miles on the original transmission.

**Bottom line:** The 2012 is a decent choice if the CVT feels smooth and the service history shows regular maintenance. But budget for that potential transmission risk—or consider an extended powertrain warranty.
