Top 10 Common Nissan Altima Problems and How to Fix Them
The Nissan Altima is known for its comfort, style, and reliability. However, like any vehicle, it can encounter issues. Here, we explore the top 10 common problems with the Nissan Altima and provide guidance on how to fix them.
1. CVT Transmission Failure
Symptoms:
- Hesitation during acceleration
- Shuddering or shaking

This can be due to a faulty camshaft or crankshaft sensor. Replacing these sensors is relatively straightforward and can often resolve the issue.
3. Excessive Oil Consumption
Symptoms:
- Low oil levels despite regular top-ups

Fix:
Excessive oil consumption may indicate worn piston rings or valve seals. This is a more complex repair, often requiring engine disassembly. It's best handled by a professional.
