2. **Transmission Problems (6T70)**

- Some **2016 2018 ATS models** report **rough shifting, delayed engagement, or transmission fluid leaks**.

- **Transmission fluid should be changed every 60,000 100,000 miles** to prevent failure.

- **Wind and road noise** can be noticeable, especially at highway speeds.

6. **Depreciation and Market Availability**

- The **Cadillac ATS has seen declining popularity**, meaning **parts and service may be harder to find** compared to more common luxury sedans.

- **Used market competition** is high, so **pricing can be aggressive** buyers must **inspect thoroughly** to avoid lemon purchases.

7. **Potential for Hidden Maintenance Costs**

- **Suspension components (struts, bushings, control arms)** wear out around **80,000 120,000 miles**.

- **Brake systems (pads, rotors, calipers)** can be expensive to replace if not maintained.

- **Exhaust leaks** (especially near the catalytic converters) are common due to **heat damage**.
