Radio Shuts Off When Put In Drive Or Reverse – updated 2023

It might not be enjoyable when your radio turns off when you put your car in drive or reverse. You might be unlikely to listen to songs, news reports, or any other auditory entertainment while driving due to this problem.

My car radio turns off while driving? First, try unplugging the trans’s top-mounted Park/Neutral switch sensor. Under the hood, this is near the cable for the transmission. Check to see whether the radio is now operational after unplugging it. If so, swap out the Park/Neutral switch and restart.

This post will look at the various reasons for this problem and several solutions.

Causes of Radio shuts off when put in drive or reverse:

Car radio shuts off while driving? Knowing the root causes of this problem is very important, so here we describe some possible causes for you related to this problem.

1. Loose or Damaged Wiring:

Why does my radio keep turning off while driving? A radio frequently shuts off when shifting gears due to loose or broken cabling. The radio may lose power due to loose connections temporarily disconnecting due to vibrations when starting the broadcast.

2. Faulty Ground Connection:

Radio turns off while driving? When shifting gears, a bad ground connection might interrupt the electrical current and turn off the radio. The ground connection offers the electrical route required for the radio to function correctly.

3. Interference from the Transmission:

Radio keeps turning off while driving? Radio and transmission system interference is a possibility in some cars. The radio might turn off due to electrical impulses generated during gear changes interfering with electronics.

4. Faulty Ignition Switch:

Radio turning off while driving? When shifting gears, an inconsistent power supply to the radio due to a bad ignition switch may cause sudden shutdowns. The radio is one of several car electrical parts powered by the ignition switch.

5. Inadequate Power Supply:

Radio turns off and on while driving? A weak power supply is another potential reason a radio would turn off when you put it in drive or reverse. It could happen if the radio consumes more power than the vehicle’s electrical system can handle, especially when the load is high, such as while shifting gears.

6. Electrical System Issues:

Why does my radio turn off while driving? In rare cases, the radio turning off when changing gears may signal more serious problems with the vehicle’s electrical system. Alternator, battery, or voltage regulator issues might disrupt the radio’s power supply and result in unanticipated shutdowns.

How To Fix Radio shuts off when put in drive or reverse?

Now we know the possible causes of this issue. Let’s discuss fixes for the radio shutting off when put in drive or reverse

1. Inspect The Wiring Harnesses:

Radio turned off while driving? Look for any wear, fraying, or loose connections in the wire harnesses around the gear shift and radio. It is advised to seek expert assistance to repair or replace the impacted parts if you discover any broken wiring.

2. Check The Ground Connections:

The radio’s ground connection is often near the back of the device; check to be sure it is firmly attached. Use a wire brush to remove any corrosion and replace the ground connection if required. It is advised to visit a qualified technician if the issue continues.

3. Install A Noise Filter:

To reduce interference, use a noise filter or a ground loop isolator. These tools aid in the reduction of undesirable electrical impulses and guarantee the radio’s flawless operation. For help choosing and installing the right equipment, speak with an audio or automotive industry expert.

4. Replace the Ignition Switch:

If required, have a qualified mechanic examine the ignition switch to see whether it has to be replaced. They will be qualified to test the ignition switch accurately and ensure it operates as intended.

5. Check Electrical Systems:

Make sure the electrical system can support the radio’s power requirements. Verify that the battery is in excellent condition and ultimately charged.

To supply enough power to the radio, consider increasing the electrical system by adding a larger battery or alternator. The optimal course of action for enhancing the power supply to the radio can be determined with the assistance of an automobile electrician or audio professional.

6. Inspected by Trained Technician:

Have a trained technician carefully examine the electrical system in your car. They’ll locate any underlying electrical issues and fix them. It may include fixing or replacing problematic parts to get the radio’s power supply working correctly.

1. Why does my radio suddenly turn off?

A receiver will automatically shut down if it does not receive enough current. The receiver may turn off on its own if there is not enough current if it shares a wall outlet with another high-current equipment (such as a heater, air conditioner, refrigerator, or vacuum).

2. Why does my radio turn off when I brake?

You may have a shaky connection that breaks down occasionally. The radio turns off when you are braking the car. A loose connector that disconnects while braking, a loose loudspeaker that slides about when braking to the point where one of the wires hits the chassis, etc., are wiring problems that might cause this.

3. Why are radio signals interrupted sometimes in a moving car?

There are sporadic interruptions in the radio signal that we hear when driving. There is a report of radio waves that interfere. Multipath interference between a radio wave and its reflection is a typical type of interference.

4. Does a fuse control the radio?

A vehicle radio typically features at least one fuse to safeguard the device against power surges or other electrical problems. This fuse will blow out and cut the circuit if the audio system receives too much current, protecting the primary radio.

5. How do you fix radio frequency interference?

Due to proper grounding, RF noise is carried away to the earth and not released as radiation. The simplest ways to stop radio frequency interference in electrical circuits are shielding, filtering, and grounding.


It might be annoying when your radio cuts out as you shift gears, but with this troubleshooting guide, you can figure out the likely causes and apply the proper repairs. Remember that it is always advised to visit a qualified technician or auto audio specialist who can identify and resolve the problem if you feel uneasy carrying out these tests yourself. You and your passengers will have a more relaxing and comfortable ride once your radio operates again.
