Motors need maintenance to keep running at their best. Minimum is flushing through with motor sparay, and using a comm cleaning stick on the commutator and brushes. If the motor is rebuildable, a commutator skim on a lathe, with new brushes, will normalyy make the motor as good as new.
Other possibility is a mechanical problem, something may have got trapped in the drivetrain, come loose, or been damaged.

-sticking brush in motor?
-car's bearings have gotten jammed, needs servicing
-something stuck in a belt
-connection/contact problem
-charger not charging your batteries fully
-batteries have gone to sleep (especially NiMH)
-bent axle?
