Yes they did: These 6 GM vehicles are ending production.
Hmmm - I think you’re confusing “Volt” for “Bolt”. The Chevy Bolt is not listed as one of the 6 cars (per your link) being cancelled and the total units of the Chevy BOLT is around 40,000 units....a long way from 200,000.
Chevrolet has significant plans for EV’s and it wouldn’t make sense to discontinue the Bolt at this time.
