Toyota Motors announced a global recall Wednesday of 7.43 million cars due to a power window problem that poses a fire risk.

The automaker said that the driver's side power window switch on some models may feel "notchy" or sticky during operation. The problem is caused by an uneven application of grease during the switch assembly process, and if commonly available lubricants are applied, a fire could result under some circumstances. No accidents or deaths have resulted from the problem, the company said.
