The warranty on an engine typically begins on the date the customer purchased the equipment new. This date is significant because it establishes a clear starting point for the warranty period, reflecting the commitment of the manufacturer to provide support and service for a specified duration after the sale. Customers expect that their warranty applies from the time they acquire the product, as this is when they assume responsibility for it and integrate it into their operations.
Starting the warranty from the purchase date aligns with consumer protection laws and standard business practices, ensuring that the customer can rely on the manufacturer for assistance regarding any defects or issues that may arise during normal use. It also guarantees that the manufacturer is held accountable for their product's performance from the moment the customer takes possession of it.
In contrast, other potential starting points like the date of manufacture or when the OEM made the equipment do not consider the actual ownership and operational context the customer experiences, making them less relevant for warranty purposes.
