General Motors Corp. and the United Auto Workers union reach a tentative deal that could end a 2-week walkout at the auto maker’s critical Malibu assembly plant in Fairfax, KS.

Voting by Local 31 on the new pact was slated for today. GM says it could resume operations as early as tomorrow.

GM reportedly also was negotiating with union representatives at the Orion Township, MI, plant about adding a third shift to increase Malibu production there. GM would not confirm whether an additional shift is under consideration.

Orion reportedly builds about 1,000 cars per day, including 220 Malibus and 780 Pontiac G6s.

Meanwhile, GM has resumed full production this week at its Arlington, TX, fullsize SUV plant and started one shift up at its Moraine, OH, midsize SUV facility.

The two plants were among more than 20 assembly and components operations affected by the strike at supplier American Axle Mfg. & Holdings Inc. UAW members employed by AAM currently are voting on a tentative deal to end the 3-month strike there.

GM had hoped to restart a second shift at its Wentzville, MO, van plant, but that remains on hold.
