The 6 Mazda 6 Years To Avoid
Here are the six years that have caused the most headaches for owners. Each section explains the main problems, gives examples, and compares them to other years.
1. 2003 Mazda 6
The 2003 Mazda 6 was the first year for this model. Many people loved its sporty look and fun driving feel. But as the first generation, it had several issues that made it a risky choice.
Main Problems:
- Engine failure was common, especially after 100,000 miles.
- Transmission problems made shifting rough or caused total breakdowns.
- Rust appeared early, especially in the wheel wells and underbody.

Comparison:
Later years improved on these issues. The 2004 Mazda 6, for example, had fewer engine problems and better rust protection.
Non-obvious insight: Many buyers believe the first year of a model is better because it’s “new.” In reality, the first year often has more problems as manufacturers fix design mistakes.
Practical tip: If you must buy a 2003 Mazda 6, check for rust and ask for proof of engine and transmission repairs.
2. 2004 Mazda 6
The 2004 Mazda 6 continued some problems from the previous year. While Mazda fixed a few issues, new ones appeared, especially with electrical systems and airbags.
Main Problems:
