### **Pros and Cons of Buying a Used Acura TLX (2016 2019) with a Left-Driver Door Mirror (VIN: 770921AB)**

#### **Pros**

1. **Reliability and Build Quality**

The Acura TLX is known for its solid engineering, particularly in the 2016 2019 models, which were built on a refined platform shared with Honda s 8th-gen Accord. The V6 engine (3.5L) and 9-speed automatic transmission are generally dependable, with fewer major issues compared to some competitors. The suspension and handling are well-balanced, offering a comfortable yet sporty ride.

2. **Strong Performance and Power**

The 3.5L V6 produces **306 310 hp** (depending on the year) and **262 268 lb-ft of torque**, delivering strong acceleration and a smooth power delivery. The 9-speed transmission (introduced in 2017) shifts smoothly, improving over the older 6-speed in earlier models. The TLX also offers a **sport-tuned suspension** (available in higher trims) for better road feel.

3. **Luxury and Comfort**

The TLX comes with premium interior materials, including leather seats, ambient lighting, a high-quality infotainment system (with Apple CarPlay and Android Auto in later models), and available features like a **head-up display, ventilated seats, and a premium audio system**. The cabin is spacious, with good rear legroom and cargo capacity ( 15.6 cu. ft.).

4. **Safety Features**

- **AcuraWatch** (2016 2017) or **AcuraWatch Plus** (2018 2019) with **forward collision warning, adaptive cruise control, and lane-keeping assist**.

- **Blind-spot monitoring and rear cross-traffic alert** (higher trims).

- **Stability control and multiple airbags**.

These systems are well-regarded and help reduce accident risks.

5. **Resale Value and Brand Prestige**

Acura maintains strong resale value compared to many domestic brands, and the TLX holds its value well due to its reputation for reliability and luxury. The brand carries a premium perception, which can be appealing if you value Acura s engineering heritage.

6. **Fuel Efficiency (Compared to V8 Alternatives)**

While not a hybrid, the V6 offers **better fuel economy than a V8** (e.g., 20 22 MPG highway vs. 16 18 MPG for a V8). This makes it a more practical choice for daily driving than a muscle car.

7. **Available AWD (2018 2019 Models)**

The **Type S and higher trims** (2018 ) offer **all-wheel drive**, which improves traction in snow and wet conditions a useful feature if you live in a region with harsh winters.

8. **Aftermarket and Maintenance Support**

Acura has a strong dealer network, and parts are widely available. The V6 engine is a common powertrain, so finding mechanics familiar with it is easier than with some niche luxury brands.

---

#### **Cons**

1. **Higher Maintenance Costs Than Japanese Competitors**

While Acura is more reliable than some American brands, its maintenance costs are **higher than Honda/Acura s smaller siblings (e.g., Accord, Civic)**. The V6 engine, while robust, requires **regular oil changes (synthetic, every 5,000 7,500 miles)** and may develop **carbon buildup** over time, which can reduce performance if not addressed. Some owners report **timing chain stretch** (though rare in these years), which can be expensive to fix if it occurs.

2. **Infotainment System Limitations (2016 2017 Models)**

The **2016 2017 TLX** uses an older **7-inch touchscreen** with a clunky interface compared to later models. While it supports **Apple CarPlay and Android Auto (2018 )**, earlier versions lack wireless charging and have a slower response. Some users find the **navigation system outdated** compared to competitors like the Lexus ES.

3. **Rear Seat Comfort and Visibility**

The **rear seats are firm and less supportive** than in some luxury sedans, which may be uncomfortable for long trips. Additionally, **rear visibility is limited** due to the tall roofline, making it harder to see out of the rear windows.

4. **Noisy Cabin (Especially in Wind)**

Some owners report **wind noise at highway speeds**, particularly with the **soft-top roof** (available on Type S). The **hardtop reduces this but adds weight**. The **V6 can also be louder than a turbocharged 4-cylinder** in competitors like the BMW 3 Series.

5. **Transmission Issues (Early 2016 Models)**

The **2016 TLX with the 6-speed automatic** (pre-2017) has had **more reported transmission problems**, including **rough shifting and delayed engagement**. The **9-speed (2017 )** is significantly smoother and more reliable. If buying a **2016 with the 6-speed**, ensure it has a **clean service history** and consider a **pre-purchase inspection**.

6. **Higher Insurance Costs**

As a luxury midsize sedan, the TLX has **higher insurance premiums** than a Honda Accord or Toyota Camry. The **Type S trim (with sport suspension and performance tires)** will cost even more to insure.

7. **Limited Availability of Certain Features**

Some **premium features** (e.g., **360-degree camera, head-up display, ventilated seats**) are **only available on higher trims** (e.g., **Type S, Luxury Package**). If you want these, you ll need to pay extra.

8. **Potential for Carbon Buildup in the V6**

The **3.5L V6 is prone to carbon deposits** on intake valves, which can reduce power and efficiency over time. This is more common in **high-mileage examples** and may require a **carbon cleaning service** (costing **$300 $600**) if symptoms like **rough idle or loss of power** appear.

9. **Resale Depreciation (Compared to Hybrids)**

While the TLX holds value well, **hybrid luxury sedans (e.g., Lexus ES Hybrid, Toyota Avalon Hybrid)** often depreciate slower due to fuel savings. If fuel efficiency is a priority, a hybrid may be a better long-term investment.

10. **Sporty Ride May Not Suit All Drivers**

The **Type S and sport-tuned models** have a **firmer suspension**, which can make for a **bumpier ride on rough roads** compared to a plush luxury sedan like the Lexus ES.

---

### **Key Considerations Before Buying**

1. **Check the Transmission History**

- **2016 models with the 6-speed** have had more transmission issues. If buying one, **verify service records** and consider a **pre-purchase inspection**.

- **2017 models with the 9-speed** are far more reliable.

2. **Inspect for Carbon Buildup**

- If the car has **over 80,000 miles**, ask the seller if **carbon cleaning has been done**. Symptoms include **rough idle, hesitation, or reduced power**.

3. **Test the Suspension and Handling**

- Listen for **clunks or rattles** when driving over bumps.

- Check if the **suspension feels too stiff or too soft** some buyers dislike the **Type S s firm ride**.

4. **Verify Maintenance Records**

- **Oil changes every 5,000 7,500 miles** are critical for the V6.

- **Timing belt replacement** (if applicable) should have been done at **105,000 miles** (though the chain is more durable).

5. **Consider the Trim Level**

- **Base TLX (2016 2017):** Decent but lacks some tech.

- **LX/Luxury Package (2018 ):** Adds **premium audio, ventilated seats, and better infotainment**.

- **Type S (2018 ):** Best performance and sporty feel, but **noisy and firmer ride**.

6. **Test Drive for Comfort**

- Sit in the **rear seats** if they re too firm, long trips may be uncomfortable.

- Check **rear visibility** some find the tall roofline obstructs vision.

7. **Budget for Potential Repairs**

- **Average annual maintenance cost:** $800 $1,200 (higher than a Honda Accord but lower than a BMW).

- **Major repairs (transmission, suspension, carbon cleaning)** can add up.
