Managers at Birmingham's Longbridge plant are understood to be considering plans to shut down car production lines until early 2010, the BBC understands.
Production of a special version of the MGTF is due to end in weeks, BBC Midlands Today's Peter Plisner said.
MG Motor UK Ltd said "no final decision has been made regarding a temporary shutdown of our production facility".
It added: "If such a decision is taken we are likely to make a statement at that time confirming our intentions."
The company added that its Longbridge-based engineering/R&D facility continues to work on future MG products, which "are being specifically developed for the UK & Western European markets".
MG Rover collapsed in 2005 with the loss of 6,500 jobs.
In May 2007 its Chinese owners opened a new car production line at Longbridge as a ceremony marked the official reopening by Nanjing Automobile Corporation.
Shanghai Automotive has since taken over the Longbridge operation.
