How To Tell If Your Car Is Bugged
-
01
Check under the car, in the wheel wells, and inside the tail lights first — most bugs go on the outside.
-
02
Also check the glove box, under the seats, and the OBD2 port for hidden devices.
-
03
Buzzing or clicking on your radio or phone can signal a hidden listening device.
-
04
A battery that drains fast or a check engine light that won't clear can point to a hardwired tracker.
-
05
Document the device before removing it, then contact authorities — never confront the suspected culprit yourself.
How to Tell If Your Car Is Being Tracked
Does your ex always seem to know where you are? Are you noticing strange noises like buzzing or clicking sounds?
This probably isn't "just paranoia." Your car could very well be bugged with a location tracking or voice recording device — and if so, you could be in danger.
In this guide, we'll walk you step-by-step through:
- Signs that your car is bugged
- How to remove the bugging device
- The next steps to take to ensure your safety
We deal with problems like this all the time. Read the safety note below before you touch anything if you suspect someone dangerous is involved — law enforcement has established procedures for these situations, and getting them involved early gives you the best shot at holding the right person accountable.
Bugged Car Checklist: Do These Things First
- Photograph the device in place before you touch or remove anything.
- Check the exterior first: under the car, in the wheel wells, and inside the tail lights.
- Check inside the car: the glove compartment, under the seats, the OBD2 port, and inside the dash.
- Check for unfamiliar wiring under the hood.
- If you can't find anything but still suspect a bug, use a bug detector.
- Contact authorities — especially if you suspect stalking or harassment — before or as soon as you remove the device.
- Once it's documented and reported, remove the device or cover it in tinfoil to block the signal. Never contact the suspected culprit yourself.
5 Tips On How To Detect Hidden Bugs In Your Car
1. Look For Unusual Devices
Start with the exterior — that's the most likely place the culprit will put it. Grab a flashlight if you need it and check:
- Underneath the car
- In the wheel wells
- Inside the tail lights
- On top of the car
Then check inside the car:
- The glove compartment
- Under the seat
- The OBD2 port under the steering wheel
- Inside the dashboard
2. Check For Unfamiliar Wiring
Examine the wires under the dashboard, in the trunk, or around the battery. Look for anything that doesn't match the colors described in your car's manual. If you find anything suspicious, photograph it and bring it to an auto body shop or contact the police.
Some tracking devices or listening bugs are disguised as part of your car's electrical system, which makes them hard to distinguish from other wires.
Pro tip: pulling and cutting wires yourself can seriously damage your car. We recommend taking it to a repair shop and asking them to check under the hood for bugs — it's worth the money.
3. Listen For Unusual Sounds
Buzzing or clicking on your radio or phone is a common giveaway. Listening devices tend to interfere with your car's electrical system, which shows up as fuzziness or static.
4. Monitor Your Car's Performance
Does the battery seem to die for no reason? Is the check engine light constantly on? Hardwired tracking devices wire directly into your car's power system and act like a parasite on your electrical system, so a device that's been running for days or weeks can drain your battery. If you're having battery or engine trouble, check under the hood or take it to a mechanic and explain the issue.
5. Use A Bug Detector
Bug detectors pick up the signals that GPS trackers, hidden cameras, or microphones emit. Scan it around your car — the detector gets more active the closer you get to the source. You need to get it close to the bug for it to register, so scan the wheel wells, under the hood, and other hard-to-reach places.
Pro tip: if this isn't the first time this has happened, get a professional investigator to help. They can track down who did it and help prevent it from happening again.
How to Remove Location Tracking Devices Once You Find Them
OBD2 Port Device
An OBD2 port device plugs directly into your car's OBD2 port, usually found under the dashboard on the driver's side (the same port used to diagnose problems).
Removing it is straightforward: reach under the dashboard, find the device, and unplug it. No special tools or skills required.
Hardwired Devices
These are trickier — usually found behind the dashboard, under the hood, or in the trunk. They're harder to spot and much harder to remove, so we recommend getting a pro to help.
If you attempt it yourself: turn off your car and disconnect the battery first, follow wires that don't seem to belong, and cut only the wires connected to the device — being careful not to cut anything else. Twist the cut ends together, wrap them with electrical tape, and reconnect the battery when done.
Pro tip: look for cables that are a different color than the ones shown in your car's manual.
Portable GPS Devices
These are the easiest to deal with — small, battery-powered trackers attached with magnets or hidden in compartments, chosen because they're easy to place and remove without installation. Pull it off, then switch it off if there's a switch, remove the batteries, or cover it with tin foil to block the signal.
What To Do Next
Whatever you do, do not contact the alleged culprit — that's only going to cause more trouble.
Contact The Authorities
Get in touch with local police and report everything, especially if you suspect stalking or harassment is involved.
Secure The Evidence
Photograph everything before and after removal, and place the device in a plastic bag without damaging it further. If you took it to a mechanic, get a statement from them too.
Be Vigilant For More Surveillance Devices
From here on, park in a garage when you can and always lock your doors. Installing a car alarm system can also help deter anyone trying to track you again.
Frequently Asked Questions
Can I Detect If My Car Is Bugged With A GPS Tracking Device?
Yes, you can use a GPS bug detector to locate GPS trackers on or in your car. These devices detect radio signals emitted by GPS trackers, alerting you to their presence. That said, many GPS tracking devices go into sleep mode when your car isn't running, which lets them dodge a bug sweep. That's why a detailed visual scan is still the best way to catch GPS spy gear on your vehicle.
Do Private Investigators Spy On Cars With GPS Bugs?
Yes. Private investigators sometimes use a GPS device when one partner suspects the other of cheating. Doing so without written consent can be illegal, so they have to be careful with their surveillance tactics. If you suspect a private investigator is bugging your car, contact law enforcement.
Can I Check My Car For Bugs Myself?
Yes, you can check your car for bugs yourself by looking for unusual devices, wiring, or listening devices inside the car. Bug detectors or endoscope cameras can also help you check for hidden devices. That said, we still recommend hiring a private detective or auto shop to perform the scan for devices hidden deeper in the car.
Is It Legal To Bug Someone's Car?
In most cases, no — bugging someone's car without their written consent is illegal. Law enforcement agencies may be able to place tracking devices on vehicles as part of an ongoing investigation with proper legal authority. If you suspect your car has been bugged without your consent, contact law enforcement and seek legal advice. This is general information, not legal advice — consult an attorney for guidance specific to your state and situation.
