Ours must be twice that age. Nevertheless, the coating of the inside pan is completely intact and we haven’t noticed any degradation at all in quality.

For anybody who wants to invest in a decent rice cooker but is concerned about the cooker having a limited life, this is what I learned years ago (2013?) from a conversation (MrLapLap served as my interpreter) with a knowledgeable Toshiba representative at the Rice Cooker section in Yodobashi Camera in Akihabara.

Don’t wash/rinse your rice in the cooking pot - not only is the rice abrasive, but the rice bran you wash away is abrasive in itself.
Don’t use it to cook brown rice (use something else, perhaps a pressure cooker)
Try to stick to just plain rice and keep additional ingredients (such as millet) to a minimum.
If you do combine rice with other ingredients in there, never use oil.

The other workaround is to try and obtain a spare inner pan at the same time you obtain your rice cooker. Some brands allow you to purchase this as a spare part, but your chances of obtaining one diminish the more time elapses from when the cooker was originally released.
