1. Transmission Problems:
This is arguably the most commonly reported problem with the 2005 Sentra. Issues can range from rough shifting to complete transmission failure. The cause is often attributed to low transmission fluid, a failing torque converter, or internal transmission wear. Regular transmission fluid changes according to the manufacturer's recommendations are crucial for preventative maintenance. Ignoring this can lead to costly repairs or even replacement.
2. Engine Issues:
While not as pervasive as transmission problems, engine-related issues have been reported. These can include:
- Engine knocking: This often points to low oil levels, worn piston rings, or other internal engine problems. Addressing this promptly is essential to prevent catastrophic engine failure.
