Although it is annoying when an RC freezes or runs slowly, the issue is frequently something very basic or straightforward. Take a deep breath and review each of these frequent and reasonably simple to remedy trouble areas before you start tearing your RC apart (or smashing it to bits).
Always verify the obvious and the easy thoroughly—you never know what you could find. Alternatively, you can rule out straightforward issues before attempting more difficult fixes and modifications.

Verify the On/Off Switches.
Even though it may be embarrassing, there are occasions when the issue is as easy as not turning on the transmitter (if it has a switch) and the remote control car. To clearly distinguish between which way is on and which is off on some RCs, you might require a flashlight. Always double-check this. Additionally, before tinkering inside your RC, make sure the switches are in the off position if simply flipping on the switch doesn’t work.
Changing the Batteries
In electric RCs, changing the batteries can get pricey and cumbersome.
Many RC issues are frequently caused by the batteries. Battery-related issues can result in running only extremely slowly, halting abruptly, or not functioning at all.
lack of batteries: Verify the transmitter and RC.
improper installation: Ensure that the batteries are properly positioned, facing the appropriate way, and fully seated in their tiny slots.
expired batteries: Consider using new batteries. Or try a new brand if you’re using a poor brand of batteries. When utilizing a battery pack, check sure it is charged completely and correctly.
Corrosion: There may be some corrosion if the car has been sitting for a while or the battery compartment has been exposed to air and moisture. Clean the battery connections in addition to changing the batteries.

Examine your antennas.
Make sure the RC’s telescoping antenna is fully extended if it is located on the transmitter (or the vehicle). An unextended antenna might not stop the RC from functioning at all, but it might reduce your range or make it run strangely.
Make sure your RC’s reception antenna is securely fastened, not bent or broken, not in contact with any metal components inside, and not dragged on the ground.
Examine your servos.
If the RC only obeys some commands from the transmitter but not others, for example, the wheels will revolve but it won’t move ahead, this could be a clue that your servos are malfunctioning.
Consider disconnecting your servos from the receiver and replugging them into a different receiver that you are certain is functional (be sure to match the frequency of the receiver and transmitter). Your servos, not the receiver or transmitter, may need repair or replacement if the RC still doesn’t respond.
Try taking the RC to a hobby store or RC club and asking for some testing assistance if you don’t feel like fiddling with the internal components or don’t have a known working receiver on hand.
Reattach the Wiring
Numerous issues might arise as a result of loose or damaged wiring. A loose wire from the engine may be blamed if the steering works but the RC won’t move.
A loose wire to the steering servo may indicate a lack of steering. If the RC doesn’t seem to be receiving any power at all and the batteries are known to be in good condition, the issue may be a loose or disconnected cable from the battery pack or battery compartment. The issue might be resolved by resoldering wires (a little more difficult) or reattaching frayed connections.
Reset Your Gears
Gear slippage may prevent your RC from operating. Your gears might not need to be changed unless they are stripped. It may only be necessary to tighten the pinion gear and realign it with the spur gear. If the RC is making a grinding noise and is immobile, this is the issue.
Fix a shattered steering arm
If the RC starts up, but it wobbles, one of the steering arms may be broken. Near the front wheels, search inside for a length of plastic that resembles the tie rods of a real car. Is one damaged? You could swap it out for a stiff piece of wire (like a coat hanger).
