We are setting up this topic to share information on any impact the current COVID-19 virus has on the auto parts industry. Sourcing, distribution, parts availability, and business impact. General questions and sharing of knowledge are welcome.
The WHO has designated this a global pandemic that is already affecting many industries, including most sectors in the automotive industry. Corporate and Independent automotive parts stores are being impacted by repair shop businesses slowing down. As you know, many parts come from China and other parts of the world, which are affected by the current pandemic.
Please share how this is impacting you and what you are seeing.
Who else is seeing industry shortages and inflation issues causing price and availability issues on auto parts? Manufacturers are short staff, supplies, and materials. Containers from China are backlogged and getting more expensive and add on top of that inflation, prices have and will continue to go up.
Chip shortages and user car prices going up, means more more for everything. New car prices are getting over sticker in some cases. Its all relative because even groceries are going up in price. Gas and oil prices as well. 🥵
