### **Pros and Cons of buying a 2024-2025 Mazda CX-90 (DGAT-66-170A) with Blind Spot Monitoring, TCS, i-Stop, and Control Switch**

1. **Premium Luxury SUV Experience**

The CX-90 is positioned as Mazda s flagship luxury SUV, offering a refined cabin with high-quality materials, ergonomic seating, and a spacious interior. The attention to detail such as soft-touch surfaces, premium audio systems (often Bose or Bang & Olufsen), and ambient lighting enhances comfort and prestige.

2. **Advanced Safety and Driver-Assistance Features**

The inclusion of **blind spot monitoring** (with rear cross-traffic alert) and **traction control system (TCS)** improves safety, especially in challenging driving conditions. The **i-Stop** (intelligent stop-and-go) system enhances fuel efficiency in stop-and-go traffic by automatically stopping and restarting the engine. The **control switch** (likely referring to the adaptive cruise control or lane-keeping assist) further supports semi-autonomous driving, reducing driver fatigue on long trips.

3. **Powerful and Efficient Engine Options**

The **DGAT-66-170A** designation suggests a **2.5L turbocharged engine** paired with an **automatic transmission** (likely an 8-speed or 10-speed). This setup delivers strong performance (around **200 250 hp**, depending on trims) while maintaining decent fuel economy for a luxury SUV. The turbocharged engine also provides better torque for towing and highway passing.

4. **Spacious and Versatile Interior**

The CX-90 offers **seating for up to seven passengers** (with a third-row bench or optional third-row seats) and a **large cargo area** (up to **22.5 cu. ft.** behind the third row). The sliding door design and panoramic sunroof add to the premium feel, making it practical for families or those needing extra space.

5. **Mazda s Skyactiv-Technology**

Mazda s **Skyactiv engine and transmission technology** ensures reliability, fuel efficiency, and smooth power delivery. The **i-STOP** system (engine stop-start) further improves fuel economy in urban driving, which is a notable advantage for city commuters.

6. **Strong Resale Value**

Mazda SUVs, particularly those with advanced features and luxury appeal, tend to hold their value well. The CX-90 s reputation for quality and reliability contributes to a favorable resale market.

7. **Comfortable Ride and Handling**

The CX-90 balances **smooth ride quality** (thanks to its suspension tuning) with **precise handling**, making it suitable for both city driving and highway cruising. The **adaptive damping system** (in higher trims) further enhances comfort on rough roads.

8. **Tech and Connectivity Features**

The CX-90 comes equipped with a **large touchscreen infotainment system** (often with wireless Apple CarPlay and Android Auto), a **digital instrument cluster**, and **premium audio**. Some trims include **360-degree cameras** and **parking sensors**, adding convenience for maneuvering.

9. **Available Hybrid Option (Potential Future Upgrade)**

While the **DGAT-66-170A** appears to be a **gasoline-only model**, Mazda has been expanding its hybrid lineup. If you re considering long-term ownership, the **CX-90 Hybrid** (when available) could offer better fuel efficiency and lower emissions without sacrificing performance.

10. **Mazda s Reputation for Reliability**

Mazda has consistently ranked among the most reliable automakers, with the CX-90 benefiting from **proven engineering, robust build quality, and strong aftermarket support**. This reduces long-term ownership concerns compared to some luxury brands.

---

1. **Higher Price Point**

As a **top-tier luxury SUV**, the CX-90 comes with a **premium price tag**, often starting above **$50,000 $60,000** (depending on trim, options, and market). This makes it less accessible compared to mid-size SUVs like the Mazda CX-5 or CX-60.

2. **Limited Third-Row Space**

While the CX-90 is spacious, the **third row is tight** for adults, offering limited legroom. It s better suited for **children or occasional passengers** rather than full-sized third-row seating.

3. **Fuel Economy Trade-offs**

Despite the **i-Stop and turbocharged engine**, the CX-90 s **fuel economy is not exceptional** for a luxury SUV. Expect around **18 22 MPG city / 25 30 MPG highway** (varies by trim). A hybrid version would improve this, but the current model is not the most efficient in its class.

4. **Competition from More Feature-Rich Rivals**

Luxury SUVs like the **Volvo XC90, Audi Q7, or BMW X5** offer **more advanced driver-assistance systems (e.g., full self-parking, advanced driver monitoring)** and **higher-end interiors**. The CX-90 is excellent but may lack some cutting-edge tech found in German or Scandinavian rivals.

5. **Resale Depreciation (Compared to Non-Luxury SUVs)**

While Mazda SUVs hold value well, they may **depreciate faster than some non-luxury brands** (e.g., Toyota, Honda) over time. If you plan to sell early, the CX-90 may not retain as much value as a more mainstream SUV.

6. **Limited Off-Road Capability**

The CX-90 is **not an off-road-focused SUV**. While it has **AWD and some traction control features**, it lacks **serious off-road tuning** (e.g., skid plates, higher ground clearance) found in vehicles like the **Land Rover Defender or Toyota Land Cruiser**.

7. **Discontinued or Phased-Out Features (Potential Confusion)**

The **DGAT-66-170A** code may refer to a **specific engine-transmission combination** that could be updated or replaced in future models. If you re concerned about long-term availability of parts or software updates, this could be a minor drawback.

8. **Some Trims Lack Luxury Brand Exclusives**

While the CX-90 is luxurious, it may not have the **same level of opulence** as a **Mercedes GLE or Genesis GV80**. Materials and finishes are high-quality but not always as lavish as those in ultra-luxury SUVs.

9. **Potential for Higher Maintenance Costs Than Compact SUVs**

As a **larger, more complex vehicle**, maintenance costs (e.g., tires, brakes, suspension) may be higher than those of a **Mazda CX-5 or Honda Pilot**. However, Mazda s reliability helps mitigate this concern.

10. **Limited Availability of Certain Trims/Options**

Some **high-end features (e.g., premium audio, advanced driver aids)** may require **additional options packages**, increasing the final price. Availability can also vary by region and dealership.

---

The **2024-2025 Mazda CX-90 (DGAT-66-170A)** is a **well-rounded luxury SUV** that excels in **comfort, safety, and refinement**, making it an excellent choice for those seeking a **premium, reliable, and spacious** vehicle. Its **advanced driver-assistance features (blind spot monitoring, i-Stop, TCS), strong engine performance, and Mazda s reputation for reliability** are major selling points.

However, its **higher price, limited third-row practicality, and fuel economy trade-offs** may not appeal to budget-conscious buyers or those prioritizing off-road capability. If you value **luxury, safety, and long-term reliability** over extreme performance or off-road prowess, the CX-90 is a **strong recommendation**.

For buyers who want **better fuel efficiency**, consider the **CX-90 Hybrid** (when available). If you prefer a **more affordable yet still luxurious SUV**, the **CX-60** (Mazda s electric SUV) or **CX-5 Touring** could be alternatives. But for those who want **the best of Mazda s flagship SUV**, the CX-90 remains a **solid and enjoyable choice**.
