Summary

The 2005 Nissan Sentra, while generally reliable, experiences some common issues related to the engine (oil consumption, catalytic converter), transmission (slipping), suspension (strut mounts, sagging), and electrical system (power windows). Many of these issues are age-related. The severity and cost of repair can vary greatly depending on the specific problem and the extent of the damage. Rust on the exterior and cracks on the dashboard are also frequent complaints.
