#### **Cons**

1. **Limited Brand Variety** Since it is a widely used part, the market is dominated by a few suppliers, which can sometimes lead to inconsistent quality depending on the seller. Buying from untrusted sources may result in counterfeit or subpar replicas.

2. **Potential Wiring Issues** In some cases, the wiring harness may not match perfectly with the vehicle s original setup, requiring slight adjustments or additional soldering. This is more common in older or modified vehicles.

3. **Not Universal** While the DLT-137 fits many Toyota/Lexus models, it is not compatible with every vehicle. Buyers must verify compatibility with their specific year, trim, and model to avoid purchasing the wrong part.

4. **Mixed Quality Control** Some users report receiving units with loose internal components or minor manufacturing defects, particularly if purchased from less reputable sellers. Inspecting the part upon arrival is advisable.

5. **Potential for Overheating** In rare cases, users have experienced the actuator overheating or seizing due to prolonged use or electrical issues. Proper installation and regular maintenance can mitigate this risk.

6. **Limited Warranty Options** Unlike OEM parts, aftermarket actuators like the DLT-137 often come with shorter or no warranties. Buyers should research seller policies before purchasing to understand their recourse in case of defects.
