1. Lack of OEM warranty: Aftermarket parts, including the Dorman 81654YGTM, don't typically come with the same level of warranty coverage as OEM parts. This means that if the part fails prematurely, you may need to pay for the replacement out of pocket.

2. Quality concerns: While many aftermarket parts are well-engineered and reliable, there is always a risk that the quality may not be as good as OEM parts. The Dorman 81654YGTM, for example, might not be manufactured to the same exacting standards as the original OEM part.
