Are (U.S.) automakers required to maintain an infrastructure of spare parts for 15-years (in the U.S. or in California)?
Reading about the GM EV-1:
The EV1's discontinuation ... to avoid potential losses in spare parts sales (sales forced by government regulations)
... maintaining a parts supply and service infrastructure for the 15-year minimum required by the state of California ...
i cannot find any any such law, either in California, the U.S., Canada, or anywhere.
Are automakers required to maintain spare parts infrastructure for 15 years?

When the EV1 leases came due, GM collected all the experimental cars and had most of them crushed to avoid liability issues and parts-availability regulations.
