1. **Potential Counterfeit or Low-Quality Copies** While Dorman is a reputable brand, purchasing from untrusted sellers (e.g., third-party marketplaces) could result in counterfeit or substandard parts. Always buy from authorized dealers or well-reviewed suppliers to avoid this risk.

2. **Limited Longevity Compared to OEM** While Dorman parts are durable, they may not last as long as genuine OEM components, especially in high-mileage or heavy-duty applications. However, for most drivers, this part should provide reliable service for years.
