## FAQ:

- How does Dodge warranty evaluation work if a product fails?: Failed units go to Dodge's US plants for evaluation — about a week in transit plus one to two weeks of analysis, and you get the findings either way. Warranty covers workmanship and material defects; failures caused by the application (lubrication, installation) fall to the customer, but the failure analysis tells you the root cause so it doesn't repeat.
