### **Pros and Cons of Buying a 2015 2020 Acura TLX (A145J1) with Electric Power Steering (EPS) Rack Assist Issues**

#### **Pros**

1. **Strong Engine and Performance**

The TLX (2015 2020) comes with a **2.0L turbocharged direct-injection engine (K20Z2)** paired with a **9-speed automatic transmission**, delivering strong acceleration and smooth shifting. The turbocharged setup provides adequate power for daily driving and highway performance, especially in the **Type S model** (when available).

2. **Comfortable and Refined Ride**

The TLX is built on a **subframe-mounted front suspension** and features **adaptive dampers** (in higher trims), which improve ride comfort on both rough roads and smooth highways. The cabin is well-insulated, reducing road noise, and the seats are supportive for long drives.

3. **Modern Infotainment and Tech Features**

The **2015 2017 models** come with a **7-inch touchscreen** (later models upgrade to **8-inch**), while higher trims (Type S, Sport, etc.) include **Apple CarPlay, Android Auto, and a premium audio system**. The **AcuraWatch infotainment system** (on later models) is user-friendly, though some users report occasional lag.

4. **Safety and Driver Aids**

- **AcuraWatch (2016 )** Lane Departure Warning, Forward Collision Warning, Adaptive Cruise Control (2017 )

- **Blind Spot Monitoring (2017 )**

- **Rear Cross-Traffic Alert**

- **Stability Control and Traction Control**

These systems enhance safety, though some features require higher trims.

5. **Good Resale Value for a Luxury Compact SUV**

Compared to competitors like the **Lexus NX or Honda Pilot**, the TLX holds its value reasonably well, especially in well-maintained examples. The **2017 models** with updated tech and safety features are more desirable.

6. **Reliability of the Turbo Engine (When Maintained Properly)**

The **K20Z2 engine** is known for being **durable if properly maintained**, especially with **regular oil changes (synthetic, 5W-30 or 0W-20 recommended)** and **coolant flushes**. Many owners report **150,000 miles** with no major issues if serviced correctly.

7. **Spacious and Practical Interior**

The TLX offers **good cargo space (30.5 cu. ft.)** and **three-row seating in the Type S (2017 )**, making it practical for families. The **panoramic sunroof** (on higher trims) adds to the premium feel.

8. **Available AWD (Super Handling All-Wheel Drive)**

The **SH-AWD system** (2016 ) provides **better traction in snow and wet conditions** compared to FWD, making it a solid choice for those needing all-weather capability.

#### **Cons**

1. **Electric Power Steering (EPS) Rack Assist Issues (Common Problem)**

The **most significant and widespread issue** in the **2015 2020 TLX** is **EPS rack assist failures**, particularly in the **2015 2017 models**. Symptoms include:

- **Heavy steering effort** (feels like manual steering)

- **Clicking or grinding noises** when turning

- **Steering wheel vibrations**

- **Complete loss of power assist** (rare but possible)

- **Check Engine Light (CEL) with P0500, P0501, or P0502 codes**

The **EPS rack assist motor** (or its wiring/harness) can fail due to **poor quality control, electrical issues, or wear**. **Acura issued a recall (2017, Campaign #17V237)** for some 2015 2016 models, but **many affected vehicles were never fixed**.

- **Repair Cost:** **$800 $1,500** (parts labor) if the rack needs replacement.

- **Prevention:** Some owners have had success with **aftermarket EPS controllers** ( $200 $400), but these are not officially supported and may void warranties.

2. **Turbocharger and Oil Consumption Issues**

- Some owners report **oil consumption** (burning oil at **1 quart per 1,000 miles**), which can lead to **low oil levels and engine damage** if unchecked.

- **Turbocharger failures** (exhaust leaks, wastegate issues) have been reported, though less commonly than EPS problems.

- **Solution:** **Strict oil maintenance (synthetic, frequent checks), and monitoring for blue smoke (exhaust) or white smoke (coolant leak).**

3. **Transmission Issues (9-Speed Automatic)**

- A few reports of **rough shifting, delayed engagement, or transmission fluid leaks** (especially in higher-mileage examples).

- **Symptoms:** Jerky acceleration, grinding in gear changes.

- **Solution:** **Regular transmission fluid changes (every 60K 100K miles)** and **checking for leaks**.

4. **Infotainment Glitches and Slow Response**

- The **AcuraWatch system (2016 )** can be **slow to respond**, especially when navigating menus.

- **Bluetooth connectivity issues** (pairing problems, audio cuts out).

- **No wireless CarPlay/Android Auto** (until 2018 models).

- **Solution:** Software updates (if available) or aftermarket head units ( $300 $600).

5. **Interior Quality and Build Variations**

- Some owners report **plastic feel in lower trims** (2015 2016) compared to **2017 models**, which have **better materials and stitching**.

- **Sunroof leaks** have been reported in some examples.

- **Rear seat comfort** is decent but not as plush as competitors like the **Lexus NX**.

6. **Rear Visibility and Parking Difficulties**

- The **TLX has a narrow rear window**, making **rear visibility limited**, especially in tight parking spots.

- **Blind spots are larger** than in some competitors (e.g., Honda Pilot).

- **Solution:** **Backup camera (standard on 2016 ), but some owners still struggle with parking.**

7. **Higher Maintenance Costs Than Japanese Rivals**

- While the **K20Z2 engine is reliable**, **Acura dealership labor rates are among the highest** in the industry.

- **Independent mechanics may not be familiar** with Acura-specific repairs (EPS, turbo, transmission).

- **Parts can be expensive** compared to Honda or Toyota equivalents.

8. **Resale Depreciation**

- The TLX **lost popularity after 2017** when Acura shifted focus to the **MDX and RDX**.

- **2015 2016 models depreciate faster** than 2017 due to **EPS issues and outdated tech**.

- **2017 models hold value better** but still lag behind Lexus or Genesis.

### **Ending Conclusion**

The **2015 2020 Acura TLX** is a **solid luxury compact SUV** with a **strong turbo engine, comfortable ride, and good safety features**, but it comes with **significant drawbacks**, particularly the **EPS rack assist failures** a **major pain point** that can turn a $25K $35K purchase into a **$3K $5K repair bill** if not addressed early.

**EPS rack assist already repaired** (or a used rack available)

**Proper service records (oil changes, transmission fluid, turbo checks)**

**No oil consumption issues**

**A higher trim (2017 with adaptive dampers, better tech)**

then it can be a **great value** for the price.

**Unexpected $1,000 repairs** within the first 50K 100K miles

**Frustration with infotainment lag and safety feature limitations**

**Higher long-term ownership costs** due to Acura s premium labor

---

### **Final Recommendation**

1. **You find a vehicle with a pre-owned EPS rack assist** (ask for proof of repair or a used rack).

2. **You are prepared for potential turbo/oil maintenance** (stick to **synthetic oil, check levels monthly**).

3. **You prefer Acura s styling and tech** over competitors like the **Lexus NX, Honda Pilot, or Genesis G80**.

4. **You can afford dealership repairs** (or have a trusted mechanic familiar with
