The Mitsubishi Diamante, a mid-size sedan produced from 1990 to 2004, offered a blend of Japanese reliability and upscale features. Choosing the right year can make a significant difference in your ownership experience. This guide provides a detailed look at the best and worst years for the Diamante, helping you make an informed decision.
The Diamante aimed to compete with more established luxury sedans. Its strengths included a smooth ride, comfortable interior, and relatively affordable price point. However, like any car, some model years are more reliable and desirable than others.
| Model Year | Key Features/Improvements | Potential Issues/Concerns |
|---|---|---|
| 1992-1994 (First Generation) | Introduced with a focus on comfort and a spacious interior. Offered with a 3.0L V6 engine. Available features included automatic climate control, power seats, and a premium sound system. Notable for its unique styling. | Early models can suffer from electrical issues and rust, particularly in areas with harsh winters. Parts availability can be a challenge due to the car's age. |
| 1995-1996 (First Generation, Minor Updates) | Received minor styling updates and improvements to the interior. Engine remained the same. | Similar issues to earlier models, although some minor improvements in build quality might be present. Rust remains a concern. |
| 1997-1999 (Second Generation) | Significant redesign with a more modern and aerodynamic exterior. Improved interior quality and updated features. Introduction of the 3.5L V6 engine, offering increased power. Enhanced safety features, including dual airbags and ABS. | The 3.5L engine, while powerful, can be prone to oil leaks and timing belt issues if not properly maintained. Some reports of transmission problems. |
| 2000-2003 (Second Generation, Facelift) | Received a facelift with revised front and rear styling. Minor interior updates. Engine options remained largely the same. Further improvements in reliability compared to earlier models. | Oil leaks and potential transmission issues remain a concern, although less prevalent than in earlier second-generation models. Parts availability is generally better than for first-generation models. |
| 2004 (Final Year) | The last year of production. Generally considered one of the most reliable years due to incremental improvements throughout the second generation. Limited production numbers. | Finding a well-maintained example might be challenging due to its age and limited production. Potential for age-related issues in rubber components and electronics. |
| Years to Potentially Avoid (1990-1991) | Early production years often have more teething problems. Prone to rust and electrical gremlins. Parts are more difficult to find. | Higher probability of encountering major mechanical issues due to age and wear. Rust is a significant concern. Parts availability is very limited. |
Detailed Explanations
1992-1994 (First Generation): These early models introduced the Diamante to the market. They were known for their comfortable ride and spacious interior, powered by a 3.0L V6 engine. The design was distinctive for its time, but these models can be prone to rust and electrical problems. Due to their age, finding replacement parts can also be a challenge.
1995-1996 (First Generation, Minor Updates): These years saw minor updates to the styling and interior. The engine remained the same. While there might be some minor improvements in build quality compared to earlier models, the fundamental issues of rust and parts availability persist.
1997-1999 (Second Generation): This generation represented a significant redesign for the Diamante. The exterior was modernized, and the interior received upgrades. The introduction of the 3.5L V6 engine provided more power. However, the 3.5L engine can suffer from oil leaks and timing belt issues if not properly maintained. Some owners have also reported transmission problems.
2000-2003 (Second Generation, Facelift): This period saw a facelift with revised front and rear styling. Minor interior updates were also implemented. The engine options remained largely the same. These models generally offer improved reliability compared to the earlier second-generation Diamantes. While oil leaks and transmission issues are still potential concerns, they are less common.
2004 (Final Year): As the last year of production, the 2004 Diamante is often considered the most reliable. This is due to incremental improvements made throughout the second generation. However, finding a well-maintained example can be difficult due to its age and limited production numbers. Age-related issues in rubber components and electronics are also a possibility.
Years to Potentially Avoid (1990-1991): The earliest production years are generally best avoided. These models are more likely to have teething problems, rust, and electrical issues. Finding replacement parts for these early models can be very difficult, making repairs challenging and expensive.
Frequently Asked Questions
Which year of Mitsubishi Diamante is the most reliable? The 2004 model year is generally considered the most reliable due to incremental improvements made throughout the second generation. However, finding a well-maintained example can be difficult.
What are the common problems with the Mitsubishi Diamante? Common problems include rust, electrical issues (especially in early models), oil leaks (particularly in the 3.5L engine), and potential transmission problems. Regular maintenance is key to mitigating these issues.
Is the Mitsubishi Diamante expensive to maintain? Maintenance costs can be moderate, but parts availability can be an issue, especially for older models. Regular preventative maintenance can help minimize unexpected repairs.
Is the 3.5L V6 engine in the Diamante reliable? The 3.5L V6 is generally reliable, but it can be prone to oil leaks and timing belt issues if not properly maintained. Ensure the timing belt is replaced according to the manufacturer's recommendations.
Are parts readily available for the Mitsubishi Diamante? Parts availability can be a challenge, especially for first-generation models. Aftermarket parts are available, but sourcing specific components may require some effort.
Conclusion
Choosing the right year of Mitsubishi Diamante can significantly impact your ownership experience. While the 2004 model year is generally considered the most reliable, later second-generation models (2000-2003) also offer a good balance of features and reliability. Thorough inspection and a detailed service history are crucial when considering a Diamante, regardless of the model year.
