Summary Verdict

The 2008 Nissan Sentra presents a mixed reliability profile. While the chassis and basic components are generally robust, potential owners should be aware of common issues such as oil consumption in both engine variants, CVT transmission failures, and electrical gremlins related to the BCM. The 2.5L engine, in particular, has a higher propensity for head gasket issues. Exterior paint degradation and interior wear are also noted. Regular maintenance, especially monitoring oil levels and addressing any transmission anomalies promptly, is crucial for maximizing the lifespan and reliability of this vehicle. Despite these potential drawbacks, the Sentra can be a dependable car if these common issues are proactively managed.
