The 2008 Nissan Altima earns a 4 out of 5 star reliability rating from RepairPal, but that score depends heavily on consistent CVT transmission maintenance.
The 2008 Nissan Altima is a statistical paradox: it ranks #14 out of 28 midsize cars for reliability, yet its CVT transmission is the single most complained-about component of the entire fourth-generation (2007–2012) lineup. Whether this car treats you well or leaves you stranded comes down to one thing—how the transmission was maintained. Here is what the data actually says and what to check before buying or keeping one on the road.
How Reliable Is The 2008 Nissan Altima?
RepairPal gives the 2008 Altima a solid 4 out of 5 stars, placing it above average for the midsize class. That rating reflects the car’s strong bones—a well-built platform with capable engines—but it does not tell the full story. The headline number assumes the CVT fluid has been changed on schedule, which many owners neglected.
The car is available as a sedan or coupe with four powertrain choices. The 2.5 S and 3.5 SE trims that come with the 6-speed manual dodge the CVT risk entirely—those are the picks for buyers who want the car’s best reliability odds. Safety is a bright spot: the sedan earned a 5-star NHTSA rating for frontal and side impact protection, and front-seat side airbags plus side-curtain airbags are standard on every trim.
| Trim | Engine | Transmission Options |
|---|---|---|
| 2.5 Base Sedan | 2.5L 4-cyl (175 hp) | Automatic |
| 2.5 S Sedan / Coupe | 2.5L 4-cyl (175 hp) | 6-speed Manual or CVT |
| 3.5 SE Sedan / Coupe | 3.5L V6 (270 hp) | 6-speed Manual or CVT |
| 3.5 SL Sedan / Coupe | 3.5L V6 (270 hp) | CVT |
| Hybrid Sedan | 2.5L 4-cyl + Electric (158 hp gas) | CVT |
The Hybrid was sold only in eight states (California, Vermont, Connecticut, Rhode Island, New York, New Jersey, Massachusetts, and Maine) due to emissions regulations. The original basic warranty ran 3 years or 36,000 miles, so any surviving example is long past coverage.
The CVT: Reliability’s Make-Or-Break Factor
The continuously variable transmission is the biggest mechanical gamble on the 2008 Altima. Symptoms of a failing CVT include jerking or shuddering at low speeds, delayed acceleration, whining or grinding noises, and slipping gears. The root cause is usually a worn CVT belt or internal wear accelerated by dirty fluid or overheating.
Prevention is straightforward but non-negotiable: Nissan recommends servicing the CVT every 40,000 to 50,000 miles using genuine Nissan CVT fluid (roughly $20 per quart). Generic transmission fluid lacks the specific friction and heat-transfer properties this CVT requires, and using it is the most common—and most expensive—mistake owners make. Others who ignored the service schedule faced transaxle replacement well before 100,000 miles.
For owners already experiencing symptoms, an aftermarket transmission cooler can help control overheating when towing or driving in heat. If you are shopping for one, check whether the CVT fluid was changed on record—if not, budget for an immediate service.
Other Known Problems To Watch For
Beyond the CVT, the 2008 Altima has a handful of issues that show up with age:
- Engine mount failure. The right side engine mount wears out, causing excessive vibration and potential transmission strain.
- Check engine light. Often triggered by a failing catalytic converter near the cylinder head—ignoring it leads to costly repairs.
- Camshaft and crankshaft sensors. A known recall covers these.
- Steering lock failure. The electronic steering column lock can fail, preventing the car from starting or the wheel from turning.
- Dashboard melting and seat rocking. Cosmetic issues carried over from earlier models that affect comfort but not drivability.
- Fuel pump O-ring leaks. Can cause a fuel smell or hard starting; worth checking on any high-mileage example.

FAQs
How many miles can a 2008 Nissan Altima last?
With diligent CVT fluid changes every 40,000 to 50,000 miles and regular maintenance, the 2008 Altima can reach 250,000 to 300,000 miles. Neglecting the transmission typically causes failure well before 100,000 miles, which is why the car’s reliability reputation is sharply divided.
Does the 2008 Altima have transmission problems?
Yes—CVT-equipped models are prone to failure if the fluid was not changed on schedule. Symptoms include shuddering, whining, delayed acceleration, and slipping. The 6-speed manual versions have no CVT issues and are mechanically more predictable.
What recalls apply to the 2008 Nissan Altima?
There are four official recalls, including one for the camshaft and crankshaft position sensors. Owners should check their VIN at the NHTSA website to see which recalls remain open. The CVT failure itself is not covered by a recall despite being the most common complaint.
