Toyota today announced that it will conduct a safety recall involving approximately 2.5 million vehicles to inspect and apply special fluorine grease to the driver’s side Power Window Master Switch (PWMS).

Toyota says the window can experience a sticky feeling during operation, which can lead to smoke or fire under some circumstances.

The “notchy” or sticky feel may be caused by an uneven application of the grease during the switch assembly process at the supplier. If the grease is not applied evenly, frequent use of the switch and normal operation may cause the grease to become carbonized and may eventually result in the deterioration of its lubricating properties, the company said in a statement.

The recall remedy will involve an inspection, switch disassembly, and application of special fluorine grease. The switch inspection and repair will be performed at no charge to the vehicle owner.

Owners of vehicles covered by this safety recall will receive an owner notification letter via first class mail starting in late October 2012. The repair will take approximately one hour depending on the dealer’s work schedule.

Today’s announcement is for U.S. market vehicles only. No other Toyota, Lexus, or Scion vehicles are involved, says Toyota.

“We are not aware of any vehicle crashes for this condition”, the company said.
