Is it possible – car radio changes stations by itself? You are probably wondering – why is it that my car radio keeps changing stations on its own? There are a variety of reasons why your car radio continues to change stations on its own. The most typical cause is that the driver pressed a button on the steering wheel by accident, or that the driver grasped the knob to change stations and spun it instead of pushing it.
Car Radio Changes Stations By Itself – Common Problems
This can also happen if your stereo system has a stuck knob. Another reason could be that you have too much static electricity in your vehicle as a result of not wiping off the water before getting in or using an air dryer to blow away humid air after washing your windows. Since none of those sound like they could be the source of your problem, there could be a problem with the wiring in your vehicle’s electrical system.

Here are some solutions to the problem, no matter what the cause is:
Button Pressed Inadvertently
This is the most prevalent reason for the problem we’re discussing. If the radio controller in the steering wheel is excessively sensitive, the button may be pressed without your knowledge.
Before moving on to the following phase, where we’ll discuss alternatives, attempt to keep your hands away from the radio control buttons on the steering wheel. This will allow you to be certain that the difficulty is not the result of a wrong button.
The Stereo’s Sticky Knob
This could be the cause of the problem if your stereo buttons are old. This problem can force your car radio to change stations by itself! In this scenario, use rubbing alcohol and a soft cloth to clean the buttons. After a press, dirt might cause the buttons to cling inside, causing the system to receive continual input. If this is the case, you’ll need to swap out the keys on your car radio.
Many stereos include replaceable faceplates that you can replace with a faceplate from the stereo’s maker. This is the preferable option for DIYers because replacing buttons necessitates extensive system disassembly as well as tinkering with wiring and circuitry. It’s not a good idea for a first-timer to try this!
Electromagnetic Interference (EMI) is a type of electromagnetic interference that occurs when
There could be some electromagnetic interference if the radio keeps changing channels without your interaction. This occurs when the audio system’s power source is with a bad connection or has a high impedance wiring arrangement.
This could also happen if your alternator fails, causing electrical problems with your vehicle’s electronic equipment, such as speakers and radios. The alternator or battery failure, on the other hand, will cause your car’s entire electric system to fail, not just the car radios. As a result, we’ll discuss that in a subsequent piece.
Instructions How To Fix Car Radio Changes Stations By Itself
You must take the following steps to resolve this issue (car radio changes stations by itself):
- Double-check the grounding
People frequently make mistakes with car stereo grounding since it’s difficult to connect to the parking brake. If you didn’t properly ground the stereo, or at least connect the ground wire to a metal item, you’re in for a lot of trouble. - Look for any exposed wires.
If the grounding is good, the electromagnetic interference may have an open wire. To find this, take the stereo apart and look for any exposed wires in the rear.
If not, check the cables that are in relation to it for any tears or cracks. When wires come into contact with any metal item, their insulation might break and create an electromagnetic field. If you detect a damaged wire, replace it. If there are any open wires, tape them up completely so they don’t get in the way. - Verify Humidity
This could be exacerbated if you live in a humid or moist environment. When there is too much humidity, the open wire connections that are close together can short out and create an electromagnetic field.
This problem can be solved by keeping some desiccant in the car, particularly near the radio.
Malfunctioning Radio Controller Wiring
If your car stereo constantly changes stations, it could be a problem with the system’s wiring. It’s possible that your stereo system will have trouble if you’ve recently been in an accident or if there’s been any damage caused by water working inside. It’s possible that the wiring has been broken, which is causing the problem.
In this scenario, you must determine the source of the problem and rectify it. If you’ve connected the cords incorrectly, that should solve the problem. If the wire is with some type of problem, simply replacing it will solve the problem.
Bug in the software
Due to firmware problems, you may have the station switch issue in the car radio even if everything is properly installed. You can resolve this by resetting your stereo to its factory preset settings.
If it doesn’t work, go to the manufacturer’s website and look for a new firmware to replace the old one. You should be all set to go!
Let’s conclude
What do we learn about the common problem – car radio changes stations by itself? Whatever the cause, you should be able to find a solution if your car radio keeps changing channels. The causes for this can vary depending on what’s wrong with your vehicle or electrical system, but it doesn’t have to be difficult!
It could be something as easy as improper grounding or connection to a metal object, an open wire causing electromagnetic interference, or high humidity in your location, among other things. Fixing these issues is frequently simple and does not want sophisticated knowledge or professional assistance!
