You may want to check if your motors are the new type 9V geared motor (#43362).
If so, please be aware it is prone to failure, the first sign being sticking. Pl

No amount of lubrication is going to help. In due course the motor will become
permanently stuck and useless. Such is the natural history.

Is this triggered by time or by usage? (i.e. will a motor that is run more
wear out faster?)

Both. Likely due to bad design and/or manufacture.
Someone at TLC is supposed to be looking into it. But I do not know what is the
outcome.
