The Infiniti M30d, a diesel-powered variant of the popular M series, offered a blend of luxury, performance, and fuel efficiency. Choosing the right year model can significantly impact your ownership experience, avoiding potential pitfalls and maximizing the car's strengths. This guide provides a comprehensive overview to help you navigate the used Infiniti M30d market and make an informed decision.
Infiniti M30d Model Years: A Quick Reference
| Feature | Description | Considerations |
|---|---|---|
| Production Years | Typically 2010-2013 (depending on the market). The M30d was primarily sold in Europe. | Check specific market availability. Ensure the model year is compatible with your region's emissions standards and vehicle regulations. |
| Engine | 3.0-liter V6 Turbo Diesel (Renault-Nissan V9X engine). Power output varies slightly depending on the year and market, but generally around 235-240 hp. | This engine is known for its decent power and fuel economy. However, like all diesel engines, it requires regular maintenance, including oil changes and filter replacements. Watch out for potential diesel particulate filter (DPF) issues, especially in cars used primarily for short trips. |
| Common Issues | DPF clogging, injector problems, turbocharger failures, electrical gremlins (especially with infotainment systems), suspension wear (especially on models with adaptive suspension), and potential issues related to the AdBlue system (if equipped). | Thoroughly inspect for these issues before purchasing. A pre-purchase inspection by a qualified mechanic specializing in diesel engines and Nissan/Infiniti vehicles is highly recommended. Pay attention to any warning lights on the dashboard. Check service history for evidence of regular maintenance and repairs. |
| Infotainment System | Early models may have less advanced infotainment systems compared to later years. Navigation systems can become outdated. | Consider the features you require from an infotainment system. Check the functionality of the navigation system, Bluetooth connectivity, and audio system. Aftermarket upgrades may be available, but consider the cost and compatibility. |
| Trim Levels & Features | Various trim levels were available, offering different levels of luxury and technology. Features could include leather upholstery, heated seats, navigation, a premium sound system, adaptive cruise control, and lane departure warning. | Research the specific features offered in each trim level. Consider which features are essential to you. Check the condition of all electronic features and ensure they are functioning correctly. |
| Reliability (General) | Generally considered reliable with proper maintenance. However, diesel engines can be more complex and potentially more expensive to repair than gasoline engines. | Regular maintenance is crucial for longevity. Factor in the potential cost of diesel-specific repairs when budgeting for ownership. Look for models with a well-documented service history. |
| Fuel Economy | Excellent fuel economy for its class, especially compared to gasoline-powered alternatives. | Real-world fuel economy can vary depending on driving style and conditions. Consider the cost of diesel fuel in your region. |
| Market Availability/Price | M30d models are less common than gasoline versions, especially in certain markets. Prices can vary depending on condition, mileage, and location. | Be prepared to search for the right vehicle. Compare prices from different sources. Factor in the cost of transportation if you need to purchase a vehicle from another region. |
| AdBlue System (if equipped) | Some later models were equipped with an AdBlue system to reduce NOx emissions. | The AdBlue system requires regular refills. Malfunctions in the AdBlue system can trigger warning lights and potentially limit engine performance. |
Detailed Explanations
Production Years: The Infiniti M30d was primarily produced between 2010 and 2013, with availability varying by market. Confirm the specific model year and its compliance with local regulations and emissions standards before making a purchase. European markets were the primary recipients of this diesel variant.
Engine: The heart of the M30d is the 3.0-liter V6 Turbo Diesel, also known as the Renault-Nissan V9X engine. This engine generally produces around 235-240 horsepower, offering a good balance of performance and fuel efficiency. Regular maintenance, including oil changes and filter replacements, is crucial for its longevity.
Common Issues: Potential problems include DPF clogging (especially in vehicles used for short trips), injector problems, turbocharger failures, electrical issues with the infotainment system, suspension wear (particularly on models with adaptive suspension), and, for later models, issues related to the AdBlue system. A thorough pre-purchase inspection is essential to identify any existing or potential problems.
Infotainment System: Early M30d models may feature less sophisticated infotainment systems compared to later versions. Navigation systems can become outdated over time. Evaluate the features offered and their functionality, considering whether aftermarket upgrades might be necessary.
Trim Levels & Features: The Infiniti M30d was available in various trim levels, each offering different levels of luxury and technology. Common features included leather upholstery, heated seats, navigation, a premium sound system, adaptive cruise control, and lane departure warning. Carefully consider which features are essential to you and verify their condition.
Reliability (General): The M30d is generally considered reliable if properly maintained. However, diesel engines are more complex than gasoline engines, potentially leading to higher repair costs. A well-documented service history is a good indicator of responsible ownership.
Fuel Economy: The diesel engine provides excellent fuel economy compared to gasoline-powered alternatives in the same class. However, real-world fuel consumption will vary based on driving style and conditions. Factor in the cost of diesel fuel in your area when assessing the overall cost of ownership.
Market Availability/Price: M30d models are less common than their gasoline counterparts, which can make finding the right vehicle more challenging. Prices will vary depending on the car's condition, mileage, and location. Be prepared to expand your search area and compare prices from multiple sources.
AdBlue System (if equipped): Some later M30d models were equipped with an AdBlue system to reduce NOx emissions. This system requires regular refills, and malfunctions can trigger warning lights and potentially limit engine performance. Ensure you understand the requirements and potential issues associated with the AdBlue system.
