Most RC cars that stop working have not broken — they have a corroded battery contact, a jammed steering servo, or hair wrapped around the rear axle.
Battery handling comes first. Toy-grade cars on AA cells should have the cells removed after every session, because leaking alkaline cells corrode the contacts within weeks. Hobby-grade NiMH packs should be discharged to about 1.0 V per cell before recharging. LiPo packs must be balanced-charged, stored at 3.8 V per cell, and never left charging unattended.
The three most common mechanical failures are the steering servo, the differential gears, and the motor brushes. Hair and carpet fibres wrap around the rear axle and stall the motor; a monthly check with tweezers prevents most of these stalls. Gears wear faster on sand and gravel, so run on smooth surfaces when possible.

Cleaning should be dry. Wipe the chassis with a soft brush, never rinse a car with electronics under a tap. A paintbrush reaches the gearbox and motor vents. After wet or dusty runs, let the car dry fully before storage to avoid rust on steel screws and bearings.
Failure order on a toy-grade car used twice a week is predictable: battery contacts corrode within 3–6 months if cells are left in, the steering servo fails or jams after 6–12 months, and the differential gears strip after 12 months or after a single run on gravel.
On hobby-grade cars, all three failure points are replaceable parts. On toy-grade cars, the servo is often integrated with the receiver board and the gearbox is sealed, so a failure usually means a new car.
