Purchasing a used Mazda6 from the 2018 to 2022 model years can be an excellent decision for buyers seeking a midsize sedan that combines style, performance, and modern technology. Throughout these years, the Mazda6 earned a reputation for its sleek design, engaging driving dynamics, and an upscale interior that rivals many luxury competitors in its class. However, as with any used vehicle, it’s crucial to conduct thorough research and inspection to ensure you’re making a wise investment. This comprehensive guide will walk you through everything you need to know to confidently buy a used Mazda6 from these model years, highlighting key areas to inspect, common issues to watch for, and tips to get the most value for your money.

Overview of the 2018-2022 Mazda6

The Mazda6 underwent a significant redesign in 2018, introducing a more refined and premium appearance both inside and out. This generation emphasized Mazda’s “Kodo” design language, which features flowing lines and a bold front grille, giving the sedan a sporty yet elegant stance. Mechanically, the car continued to offer a choice between a naturally aspirated 2.5-liter four-cylinder engine and, from 2018 through 2021, an available turbocharged 2.5-liter four-cylinder engine that boosted power and torque for a more spirited driving experience.

Inside, the Mazda6 is known for its driver-focused cockpit, high-quality materials, and upgraded infotainment system. Apple CarPlay and Android Auto compatibility became standard or available options during these years, improving connectivity. Safety features such as adaptive cruise control, lane-keeping assist, and automatic emergency braking were also widely offered, making the Mazda6 a well-rounded choice in the midsize sedan segment.

Key Factors to Consider When Buying a Used Mazda6 (2018-2022)

1. Vehicle History and Ownership Records

Before purchasing any used car, obtaining a comprehensive vehicle history report is essential. Services like Carfax or AutoCheck can reveal vital information such as prior accidents, flood damage, title issues, odometer discrepancies, and maintenance history.

  • Accident History: While minor fender benders may not be deal-breakers, avoid vehicles with major structural damage or repeated accident reports.
  • Maintenance Records: Regular oil changes, tire rotations, and scheduled servicing indicate that the previous owner cared for the vehicle properly.
  • Number of Owners: Fewer previous owners often mean better continuity in maintenance and care.
  • Recall Status: Check whether the vehicle has any outstanding recalls and confirm if those have been addressed.

2. Engine Options and Performance

The 2018-2022 Mazda6 primarily comes with two engine options:

  • 2.5-liter Naturally Aspirated Inline-4: Produces around 187 horsepower and 186 lb-ft of torque. This engine offers a balanced mix of fuel efficiency and adequate power for daily commuting and highway driving.
  • 2.5-liter Turbocharged Inline-4: Available on select trims up to 2021, this engine increases output to up to 250 horsepower and 310 lb-ft of torque when using premium fuel. It delivers brisk acceleration and a sportier driving experience.

When inspecting the engine, listen carefully for any unusual sounds such as knocking, ticking, or excessive rattling. Check for oil leaks around the valve cover and oil pan, which can sometimes be an issue with higher-mileage models. The turbocharged variants should be checked specifically for signs of turbo lag or boost pressure irregularities.

3. Transmission and Drivetrain

The Mazda6 uses a smooth-shifting 6-speed automatic transmission, which generally performs reliably if properly maintained. During your test drive, pay attention to:

  • Shift Quality: The transmission should shift seamlessly without hesitation, jerking, or slipping.
  • Delayed Engagement: When shifting from park to drive, there should be no unusual delay.
  • Transmission Fluid Condition: If possible, have a mechanic inspect the transmission fluid for discoloration or burnt smell, which can indicate internal wear.

Note that Mazda6 models are front-wheel drive, with no all-wheel-drive option available. Consider your climate and driving conditions to ensure front-wheel drive suits your needs.

4. Infotainment and Technology Features

From 2018 onward, Mazda upgraded the Mazda Connect infotainment system to support smartphone integration features like Apple CarPlay and Android Auto, initially as options and later standard on higher trims. When evaluating a used Mazda6, make sure to test the following:

  • Touchscreen Responsiveness: Ensure the screen responds quickly and displays clearly without flickering or freezing.
  • Smartphone Connectivity: Pair your phone to test Apple CarPlay/Android Auto functionality, including calls, messaging, and navigation apps.
  • Audio System: Listen for distortion or static at various volume levels. Higher trims may include premium Bose audio systems worth verifying.
  • Other Electronics: Check that climate controls, power windows, seat adjustments, and other electronic features operate correctly.

5. Interior and Exterior Condition

Careful inspection of the vehicle’s exterior and interior can provide insight into how well the car was maintained:

  • Exterior Inspection: Look for dents, scratches, paint inconsistencies, and signs of rust, especially around the wheel wells and undercarriage. Check for uneven panel gaps that may indicate prior body repairs.
  • Tires and Suspension: Uneven tire wear could point to alignment issues or suspension problems. Confirm that tires have adequate tread depth and are of consistent brand and model across all four corners.
  • Interior Wear: Examine seats for tears, stains, or excessive wear. Leather seats may need conditioning, while cloth seats should be free of persistent odors.
  • Dashboard and Controls: Verify that buttons, knobs, and switches are intact and functional. Look for cracks or fading on the dashboard, which can occur due to sun exposure.

6. Safety Features and Ratings

The Mazda6 from these years is equipped with a suite of advanced safety features, many of which contribute to its strong safety ratings from organizations such as the Insurance Institute for Highway Safety (IIHS) and the National Highway Traffic Safety Administration (NHTSA).

  • Standard Safety Equipment: Features like blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, lane departure warning, and automatic emergency braking are common, especially on higher trims.
  • Crash Test Ratings: The Mazda6 consistently earned top marks in frontal and side crash tests, making it one of the safer choices in the midsize sedan category.

When buying used, confirm that all these safety systems are operational and have not been disabled or damaged during prior accidents.

7. Test Drive Tips

A thorough test drive is the best way to evaluate the Mazda6’s condition and driving dynamics. Consider the following:

  • Acceleration and Power Delivery: Whether naturally aspirated or turbocharged, the car should accelerate smoothly without hesitation.
  • Steering and Handling: The Mazda6 is praised for its responsive steering and composed handling; make sure the steering feels tight and centered without excessive play or vibration.
  • Braking Performance: Brakes should engage firmly and evenly without noise or pulsing.
  • Ride Comfort: The suspension should absorb bumps and road imperfections without harshness.
  • Noise Levels: Listen for excessive road, wind, or engine noise that could indicate worn seals or insulation issues.

Common Issues to Watch For

While the Mazda6 is generally reliable, some issues have been reported by owners and professional reviewers. Being aware of these can help you avoid costly repairs:

  • Infotainment Glitches: Some owners have reported occasional software bugs in the Mazda Connect system, such as freezing or delayed response. Ensure the system is updated to the latest firmware.
  • Brake Wear: Premature brake wear has been noted in some cases, so inspect brake pads and rotors carefully.
  • Turbocharged Engine Concerns: On turbo models, watch for signs of oil consumption or turbocharger issues, especially if maintenance records are incomplete.
  • Interior Wear on Base Models: Lower trims may have less durable materials that show wear more quickly, especially on seats and door panels.
  • Windshield Cracking: Some owners have experienced windshield cracking due to the design and type of glass used; check for chips or cracks before purchasing.

Trim Levels and Options to Consider

The Mazda6 from 2018 to 2022 was offered in several trim levels, each with varying features and price points. Understanding these trims can help you decide which model fits your needs and budget:

  • Sport/Base: The entry-level trim includes the 2.5-liter engine, cloth upholstery, and basic infotainment. It’s a good choice for budget-conscious buyers but lacks some advanced features.
  • Touring: Adds leatherette or optional leather seats, upgraded wheels, and additional driver assistance features.
  • Grand Touring: Features leather seats, premium audio, advanced safety tech, and the turbocharged engine option (on models prior to 2022).
  • Signature: The top-tier trim includes Nappa leather upholstery, wood interior accents, premium Bose audio, and exclusive exterior styling elements.

Note that the turbocharged engine was discontinued after the 2021 model year, so 2022 models come only with the naturally aspirated 2.5-liter engine. Buyers seeking the turbocharged powertrain should focus on 2018-2021 models.

Pricing and Value Considerations

Used Mazda6 prices vary depending on model year, trim, mileage, condition, and location. Generally, these sedans hold their value well due to their reliability and desirability. To get the best deal:

  • Compare prices across multiple listings and dealerships.
  • Look for certified pre-owned (CPO) Mazda6 vehicles that come with extended warranties and thorough inspections.
  • Negotiate based on mileage, condition, and any needed repairs or maintenance.
  • Factor in insurance costs, fuel economy, and potential maintenance expenses.

Maintenance and Ownership Tips

Once you’ve purchased a used Mazda6, proper maintenance is key to ensuring it remains reliable and enjoyable to drive. Here are some recommendations:

  • Regular Oil Changes: Follow Mazda’s recommended service intervals, typically every 5,000 to 7,500 miles depending on driving conditions.
  • Tire Rotation and Alignment: Rotate tires every 5,000 to 7,500 miles and check alignment annually to ensure even tire wear.
  • Brake Inspection: Have brakes inspected regularly, especially if you notice any squealing or reduced responsiveness.
  • Software Updates: Visit a Mazda dealer for any available infotainment or engine control unit (ECU) software updates.
  • Turbocharged Engine Care: For turbo models, use premium fuel as recommended and avoid aggressive driving when the engine is cold to preserve turbo longevity.

Conclusion

The 2018-2022 Mazda6 stands out as a midsize sedan that offers a compelling combination of style, comfort, technology, and driving enjoyment. When buying a used model from these years, paying close attention to the vehicle’s history, mechanical condition, and features will help you find a car that delivers excellent value and dependable performance. Conduct a thorough inspection, take a detailed test drive, and consider certified pre-owned options to maximize peace of mind. With proper care, a used Mazda6 can be a rewarding daily driver that blends practicality with a touch of sportiness for years to come.
