Mazda CX-8: The Comprehensive Guide

The Mazda CX-8 is a mid-size crossover SUV primarily targeted towards Asian markets, offering a blend of Mazda's signature driving dynamics with the practicality of a three-row vehicle. Positioned as a slightly smaller and more affordable alternative to the CX-9, it caters to families needing extra seating without requiring the full size of a traditional SUV. This guide delves into the CX-8's history, generations, reliability, driving experience, and offers some helpful buying advice.

Generations

First Generation (2017-Present)

The CX-8 has only had one generation since its introduction in late 2017. While it hasn't undergone a complete redesign, it has received several updates and facelifts.

• 2017 Launch: The CX-8 debuted with a focus on the Japanese market. Key features included the Skyactiv-G 2.5-liter naturally aspirated petrol engine and the Skyactiv-D 2.2-liter diesel engine, both paired with a 6-speed automatic transmission. Seating configurations for six or seven passengers were available.
• 2018 Update: Minor updates included enhanced sound insulation and improved suspension tuning for a more refined ride.
• 2019 Update: Introduction of Mazda's G-Vectoring Control Plus (GVC Plus) for improved handling and stability. Slight interior trim updates were also implemented.
• 2020 Facelift: A significant facelift brought revised front and rear styling, incorporating Mazda's evolved Kodo design language. The diesel engine received upgrades to improve fuel efficiency and reduce emissions. The infotainment system was also updated.
• 2022 Facelift: This update included further refinements to the front fascia, new wheel designs, and enhanced interior features. Improvements were made to the i-Activsense suite of safety technologies.
• 2023 Model Year: Small tech improvements.

Reliability & Common Issues

The Mazda CX-8, based on the Skyactiv platform, generally enjoys a reputation for good reliability. However, like any vehicle, it has some potential problem areas to be aware of:

Diesel Engine (Skyactiv-D 2.2) Issues:

• Carbon Buildup: This is a common concern with modern diesels, especially those used primarily for short trips. Carbon buildup in the intake manifold can lead to reduced performance, increased emissions, and potentially costly repairs. Regular long drives at highway speeds and the use of high-quality diesel fuel with detergents can help mitigate this issue. Consider getting the intake manifold cleaned periodically (e.g., every 50,000 km).
• Diesel Particulate Filter (DPF): The DPF can become clogged if the vehicle is mainly driven in urban environments where it doesn't get the opportunity to regenerate properly. Look for warning lights related to the DPF. Forced regeneration by a mechanic may be required in some cases.
• Injector Issues: Diesel injectors are highly precise components, and they can be susceptible to wear and tear, particularly if exposed to poor-quality fuel. Symptoms include rough idling, poor fuel economy, and misfires.
• Timing Chain Stretch: Although not extremely common, some reports suggest potential for timing chain stretch in higher mileage diesel engines. Listen for rattling noises upon startup.

Petrol Engine (Skyactiv-G 2.5) Issues:

• Direct Injection Carbon Buildup: Similar to the diesel, direct injection petrol engines are susceptible to carbon buildup on the intake valves. While generally less severe than with diesels, it can still impact performance over time. Fuel additives designed to clean fuel injectors can help.
• Oil Consumption: Some owners have reported slightly higher than normal oil consumption, particularly in earlier models. Monitor oil levels regularly.

General Issues:

• Infotainment System Glitches: Some owners have reported occasional glitches or freezing issues with the infotainment system. Check for software updates, which often resolve these problems.
• Automatic Transmission: While generally reliable, ensure the transmission shifts smoothly during a test drive. Jerky shifting or hesitation could indicate a potential problem. Proper servicing according to the maintenance schedule is vital.
• i-Activsense System Calibration: The i-Activsense suite of safety features relies on sensors and cameras. Proper calibration is essential for these systems to function correctly. Ensure that all safety systems are working as intended during a test drive and check for any error messages.

Recommendation: A thorough pre-purchase inspection by a qualified mechanic is highly recommended, especially for diesel-powered models. Pay particular attention to the engine, transmission, and DPF.

Driving Experience

The Mazda CX-8 aims to deliver a more engaging driving experience than many of its competitors in the three-row crossover segment. Here's a breakdown of the pros and cons:

Pros:

• Agile Handling: The CX-8 benefits from Mazda's focus on driving dynamics. It feels relatively nimble and responsive for its size, with well-weighted steering and controlled body roll in corners. G-Vectoring Control (GVC) and GVC Plus further enhance stability and driver confidence.
• Refined Ride: The suspension is well-tuned to provide a comfortable ride, even on rough roads.
• Responsive Engines: Both the petrol and diesel engines offer adequate power for most driving situations. The diesel, in particular, provides strong torque for effortless acceleration.
• Premium Interior: Mazda interiors are known for their quality materials and thoughtful design. The CX-8's cabin is generally well-appointed and feels more upscale than some of its rivals.
• Relatively Compact Size: Compared to the CX-9, the CX-8 is easier to maneuver and park in tight spaces.

Cons:

• Third-Row Space: The third row is best suited for children or smaller adults on shorter journeys. Legroom is limited compared to larger SUVs.
• Fuel Economy (Diesel): While the diesel engine offers good fuel economy in highway driving, fuel economy can be poor when primarily driving in urban environments.
• Infotainment System (Older Models): The infotainment system in pre-facelift models can feel dated compared to newer systems. The screen is also smaller in these models.
• Engine Noise (Diesel): Some may find the diesel engine a bit noisy, especially under hard acceleration.

Buying Advice

Here's some advice to help you make an informed decision when buying a used Mazda CX-8:

Years to Look For:

• 2020 Facelift and Newer: These models benefit from the updated styling, improved infotainment system, and refined diesel engine. The i-Activsense system is also more advanced in these models.
• Consider 2019 Models with GVC Plus: If budget is a concern, the 2019 models with GVC Plus offer a noticeable improvement in handling compared to earlier models.

Years to Avoid (Potentially):

• Early Production (2017-2018) Diesels: These models may be more prone to carbon buildup and DPF issues due to being earlier iterations of the engine. However, this greatly depends on how well they were maintained.

Key Considerations:

• Diesel vs. Petrol: Consider your driving habits. If you primarily drive short distances in urban areas, the petrol engine may be a better choice to avoid potential diesel-related issues. If you do a lot of highway driving, the diesel may be more economical.
• Service History: Always check the service history to ensure the vehicle has been properly maintained. Regular oil changes and other preventative maintenance are crucial, especially for diesel engines.
• Pre-Purchase Inspection: As mentioned earlier, a thorough inspection by a qualified mechanic is highly recommended.
• Test Drive: Take the vehicle for a test drive in various conditions (city, highway, hills) to assess its performance and identify any potential issues. Pay attention to engine smoothness, transmission shifting, and brake performance.
• Negotiate: Don't be afraid to negotiate the price, especially if the vehicle has any known issues or high mileage.
