### **Pros and Cons of Buying a 2025 Mazda CX-90 with the Specs: 6K LKQ440031645 (6-Speed Automatic Transmission)**

1. **Premium Brand Reputation** Mazda is known for reliability, driving dynamics, and a strong resale value compared to many competitors. The CX-90 is positioned as a luxury crossover, offering a refined interior and sporty handling.

2. **Spacious and Practical Interior** The CX-90 is designed for families or those needing extra space, with a large cargo area (up to 95.5 cu. ft. with seats folded) and a comfortable three-row layout. The third row is more practical than some rivals, offering decent legroom for adults.

3. **Strong Engine Options** The 2025 CX-90 is expected to come with a **2.5L turbocharged 4-cylinder (250 hp)** or a **3.5L V6 (300 hp)**. The V6 option provides strong towing capacity (up to 5,000 lbs) and better acceleration, making it suitable for those needing power without the complexity of a diesel or hybrid.

4. **Advanced Safety Features** Mazda s **Skyactiv Technology** ensures fuel efficiency and reliability, while standard safety tech like **i-Activsense** (adaptive cruise control, blind-spot monitoring, lane-keeping assist, and automatic emergency braking) enhances safety. The CX-90 also earns high ratings in crash tests.

5. **Comfortable Ride and Quiet Cabin** The CX-90 is designed for a smooth, quiet ride, with good sound insulation and well-tuned suspension. This makes it ideal for highway driving and long trips.

6. **Luxury Amenities** The CX-90 offers premium materials, heated/ventilated seats, a high-quality infotainment system (likely with wireless Apple CarPlay/Android Auto), and available features like a panoramic sunroof and ambient lighting.

7. **Good Fuel Economy for a Large SUV** The 2.5L turbo engine achieves around **20-22 MPG city / 27-30 MPG highway**, which is competitive for a three-row SUV in its class. The V6 will be slightly less efficient but still reasonable ( 18-20 city / 24-26 highway).

8. **Resale Value** Mazda SUVs hold their value well, and the CX-90 s positioning as a premium alternative to German brands (without the maintenance costs) makes it a smart long-term investment.

9. **Available Hybrid Option (Expected)** While not confirmed for all markets, Mazda has hinted at a **hybrid variant** for the CX-90, which would improve fuel economy and reduce emissions without sacrificing power.

10. **Strong Aftermarket Support** Mazda has a loyal following, and parts, tuning, and maintenance are widely available. The 6-speed automatic transmission (6K LKQ) is a common and well-supported unit.

---

1. **Higher Price Tag** The CX-90 is positioned as a luxury crossover, meaning it will be more expensive than mainstream competitors like the Honda Pilot or Toyota Highlander. The V6 model will be significantly pricier than the 4-cylinder.

2. **Third Row is Narrow** While functional, the third row is tight for adults, especially in the rear seats. Passengers may feel cramped on long trips compared to vehicles like the Ford Explorer or Chevrolet Traverse.

3. **Transmission Reliability Concerns (6K LKQ)**

- The **6K LKQ** is a **6-speed automatic** used in several Mazda models (CX-9, CX-5, CX-30, etc.). While generally reliable, some owners report **rough shifting, delayed engagement, or electronic issues** (e.g., transmission control module failures).

- If this transmission has been in a previous vehicle, it may have **wear or fluid degradation**, leading to future problems. Always check service records.

- Mazda s **Skyactiv-Drive** transmissions are known to be more precise than traditional automatics but can be sensitive to neglect (e.g., low fluid, dirty filters).

4. **Limited Off-Road Capability** Unlike the Subaru Ascent or Jeep Grand Cherokee, the CX-90 is not marketed as an off-road SUV. It has **standard AWD (if equipped)**, but traction control is more for light snow and mud than serious off-roading.

5. **Infotainment System Limitations** While the CX-90 s touchscreen is user-friendly, some users report **lag or occasional glitches**. The lack of a digital gauge cluster (in base trims) may feel outdated compared to rivals.

6. **Fuel Economy Trade-Offs** The V6 model sacrifices efficiency for power. If fuel costs are a concern, the 2.5L turbo may be a better choice, though it lacks the V6 s towing capability.

7. **Dealer Markups on New Models** Like many luxury SUVs, the CX-90 may come with **high dealer fees or optional packages** that inflate the final price. Always compare MSRP vs. actual quoted price.

8. **Limited Availability of Parts in Some Regions** While Mazda has a strong global presence, certain trim-specific parts (e.g., rare interior fabrics, specific lighting) may take longer to source in some markets.

9. **Resale Depreciation** While Mazda SUVs hold value well, luxury crossovers still depreciate faster than smaller cars. If you plan to upgrade frequently, this could add up.

10. **Potential Early Model Teething Issues** As a **2025 model**, there may be **unreported bugs or software glitches** that get fixed in later production runs. Buying early in the model year could mean dealing with minor issues before they re resolved.

- **Transmission History** If this transmission (6K LKQ) has been in a previous vehicle, **request a full service history** and consider a **pre-purchase inspection (PPI)**. Check for:

- **Fluid condition** (should be fresh, not burnt or dark).

- **Shift smoothness** (no jerks, hesitation, or delayed engagement).

- **No check engine or transmission warning lights**.

- **Test Drive Focus Areas**

- **Transmission response** (accelerate from a stop, check for smooth upshifts).

- **Braking and handling** (listen for unusual noises, check for vibrations).

- **Third-row comfort** (if applicable, ensure it s usable for your needs).

- **Financing vs. Leasing** The CX-90 is expensive, so weigh whether **buying outright, financing, or leasing** makes the most sense for your budget.

- A **used CX-90 with a known good transmission** (e.g., 2022-2023 models).

- A **competitor like the Honda Pilot (9-speed auto), Toyota Highlander (8-speed), or Subaru Ascent (CVT)** for different trade-offs.

You prioritize **reliability, comfort, and driving dynamics** over raw off-road capability.

The **transmission has a clean service history** (fluid changes, no major issues).

You re okay with **higher upfront costs** for a premium SUV with strong resale value.

The **2.5L turbo engine** meets your power needs (or the V6 is essential for towing).

You **test drive thoroughly** and confirm no transmission or mechanical red flags.

The **transmission shows signs of wear** (rough shifts, delayed response, burnt fluid).

You **need a more spacious third row** (consider the Ford Explorer or Chevrolet Traverse).

You re **sensitive to luxury SUV pricing** and can find a well-equipped alternative at a lower cost.

You **plan to modify the vehicle heavily** (Mazda s warranty may not cover aftermarket changes).

---

- **For a New Buyer:** If you re purchasing directly from a dealer, **negotiate hard** on the price (especially if the model is new and may have incentives). Ensure the dealer provides a **full warranty** and **transmission service records**.

- **For a Used/Pre-Owned Buyer:** If buying a **2024 or 2023 CX-90 with the same transmission**, verify its history and consider a **PPI** to avoid transmission-related surprises.

- **Alternative:** If transmission reliability is a major concern, look for a **CX-90 with a different transmission** (e.g., the **6-speed ZF 6HP26**, used in some European-market Mazdas) or a **competitor with a proven automatic** (e.g., Toyota s 8-speed, Honda s 9-speed).

**Bottom Line:** The Mazda CX-90 is a **well-built, comfortable, and capable
