1. Cost: OEM parts can be more expensive than aftermarket alternatives. This switch may cost more than a comparable aftermarket part from a different manufacturer.

2. Availability: OEM parts may not be as readily available as aftermarket parts from various suppliers. You may need to order it online or visit a dealership to purchase it.

3. Longer Lead Time: Since the part is an OEM part, it may take longer to arrive. Dealerships may have to order it from the manufacturer, which can add several days to the delivery time.
