The Massachusetts Bay Transportation Authority is going after the Springfield company under contract to produce new subway cars.
The Boston Globe reports a letter was sent to CRRC by MBTA deputy director Mark DeVitto which said there are a number of unresolved quality issues.
DeVitto alleged that CRRC has abandoned its commitment to supporting quality management, which has led to major disruptions to the new Orange and Red Line cars.
The letter came days before the T pulled several Orange Line cars out of service.
CRRC is maintaining that it continues to work with the T, and the company is blaming supply chain and workforce issues stemming from COVID-19.
Governor Maura Healey, in her inaugural address has called for a safer MBTA system.
