A U.S. brand attached to a vehicle that could not be fixed by the manufacturer within the requirements of the issuing state’s requirements. The definition of a lemon varies from state to state, but once a vehicle is branded a lemon, there are various legal remedies available to the consumer, which may include the manufacturer buying back or replacing the vehicle. Note that the warranty was likely nullified when this brand was applied.
As lemon brand issued by one jurisdiction may not carry over to another, the vehicle may still be considered safe for operation on public roads in another jurisdiction.
We would advise that you get the vehicle inspected to verify its current condition and that you speak with your provincial motor vehicle registration authority for more information regarding the ability to register and operate the vehicle in your province.
