Is it penny and Giles control system?
If so yes they wear out...
Can be replaced though.

Wheelchair manufacturers dont know or do very much. They buy in wheels (the
wrong ones usually) tyres (also the wrong ones) batteries (ditto) and
control systems such as the Penny and Giles ones above where they
(powerchair manufacturer) typically aim cheap and too small (amps). They
also buy in inhibit switches, seating actuators etc. plugs and sockets,
cables, bolts, motors etc.
They are only really responsible for the overweight badly designed bracketry
that holds it all together. The frame. And the seat. So most of this stuff
is available better and cheaper elsewhere.
It could be a P&G controller, though if it's a reasonably late-model it
will more than likely be one of prides QLogic controllers.
