Yes, you can sue someone for putting a tracker on your car in most situations. Secretly attaching a GPS device to a vehicle you own typically supports civil claims for invasion of privacy, trespass to your property, and in serious cases intentional infliction of emotional distress. The same conduct is a crime in many states, which strengthens the civil case. What you can recover, and how quickly you have to act, depends on your state’s laws, who planted the device, and how well you preserve the evidence.
The Civil Claims You Can Bring
Three causes of action do most of the work in unauthorized tracking lawsuits. You can plead them together.
Intrusion Upon Seclusion
This is the core privacy claim. You have to show that someone intentionally intruded into your private affairs in a way a reasonable person would find highly offensive. Secret GPS tracking almost always clears that bar. Courts recognize that continuous location monitoring reveals medical visits, personal relationships, daily routines, and other intimate details. You don’t need to prove a dollar of financial loss for this claim. The invasion itself is the harm.
Trespass to Personal Property
Physically attaching a device to your vehicle without permission is interference with your property. You don’t have to show the tracker damaged the car, only that someone intentionally placed a foreign object on it without consent. The Supreme Court’s reasoning in United States v. Jones reinforced that attaching a tracker to a vehicle is a physical intrusion on a constitutionally protected effect, which supports the trespass theory in civil litigation.1Legal Information Institute (LII) at Cornell Law School. United States v. Jones
Intentional Infliction of Emotional Distress
If the tracking caused severe anxiety, fear, or psychological harm, you may have a standalone emotional distress claim. Courts set a high bar: the conduct has to be extreme and outrageous, not merely unsettling. Sustained covert tracking by a stalker or abusive ex-partner tends to meet that threshold. Isolated, short-duration tracking by a suspicious spouse is harder to win on this theory alone, though it can still support the other two claims.
What Damages You Can Recover
A successful lawsuit can produce several types of monetary awards, and they can stack.
- Compensatory damages cover actual losses: therapy costs, lost wages from time spent dealing with the situation, expenses for professional vehicle sweeps, and the cost of security measures you took in response.
- Emotional distress damages compensate for anxiety, fear, sleep loss, and diminished sense of safety. You don’t need a medical diagnosis, but counseling records make the claim significantly stronger.
- Punitive damages punish particularly malicious or reckless behavior and deter others. They aren’t tied to your actual losses and can be substantial.
- Statutory damages, available in some states, provide a fixed award for privacy violations without requiring you to prove every dollar of loss.
Most tracking cases are won or lost at the damages stage. People who document nothing recover far less than people who keep records from the start. Save receipts for every related expense, keep a journal of how the tracking has affected your daily life, and start counseling early if you’re experiencing anxiety, both for your wellbeing and because those records become evidence.
How Long You Have to File
Every state imposes a statute of limitations on civil claims, and missing the deadline ends your right to sue. For privacy torts like intrusion upon seclusion or trespass to personal property, the filing window ranges from one to six years depending on the state and the specific cause of action.
Many states apply a discovery rule that starts the clock when you actually find the tracker, or reasonably should have found it, rather than when the device was first planted. This matters because trackers are designed to be hidden and you might not discover one for months. Even so, once you find a device, move quickly. Consulting a lawyer within a few weeks protects your filing deadline and your ability to preserve evidence before it disappears.
What to Do the Moment You Find a Tracker
The evidence you collect in the first hours after discovery can make or break your case. Sequence matters.
Photograph everything before touching anything. Take close-up photos and video showing the tracker’s exact position, any identifying marks or serial numbers, and how it’s attached. Use your phone’s timestamp feature and include a wide shot that clearly shows the device in context on the car.
Call the police and file a report. Even if you’re unsure criminal charges will follow, a police report creates an official record with a date and case number. Officers may want to collect the device themselves or connect it to an ongoing investigation. Don’t remove the tracker before talking to law enforcement. They may prefer to leave it in place temporarily to gather intelligence on whoever is monitoring the signal.
Consider a professional vehicle sweep. A Technical Surveillance Countermeasures inspection checks for devices you might miss on your own. Some trackers are hardwired into a car’s electrical system or tucked inside body panels. A sweep runs between $500 and $1,500 depending on the vehicle and how thorough the search needs to be. That cost is a recoverable expense in a civil lawsuit.
Your phone can also help. Apple and Google jointly developed an industry standard for detecting unwanted Bluetooth trackers. iPhones running iOS 17.5 or later and Android phones running version 6.0 or later will alert you if an unknown tracker like an AirTag has been moving with you.2Apple. Apple and Google Deliver Support for Unwanted Tracking Alerts in iOS and Android Not every GPS tracker uses Bluetooth, so these alerts won’t catch every device.
Criminal Charges and Protective Orders Run Alongside the Lawsuit
A civil lawsuit is how you get compensated. A criminal case punishes the person who tracked you, and the two tracks reinforce each other.
At least 26 states and the District of Columbia have passed laws addressing unauthorized location tracking. In roughly a dozen of those jurisdictions, tracking someone without consent falls under stalking statutes. Another nine states specifically prohibit installing a GPS device on a motor vehicle without the owner’s consent as a standalone offense.3National Conference of State Legislatures. Private Use of Location Tracking Devices – State Statutes A criminal conviction strengthens the parallel civil suit by establishing the tracking was unlawful. States without tracker-specific statutes often cover the conduct under general stalking or harassment laws.
Federal stalking law applies when someone uses interstate commerce infrastructure to place you under surveillance with intent to harass, intimidate, or injure, and the conduct causes substantial emotional distress or reasonable fear of serious harm.4Office of the Law Revision Counsel. 18 USC 2261A – Stalking Trackers that transmit location data over cellular networks use that infrastructure.
If you know who placed the tracker and fear for your safety, a protective order gives you immediate legal protection while you pursue the lawsuit. Emergency orders can be granted the same day without the other person present. A judge evaluates whether you face an immediate safety threat, and sustained GPS tracking by someone with a history of threats, controlling behavior, or domestic violence is the kind of evidence that persuades judges to act fast. Once in place, the order can prohibit contact, approach, and any electronic monitoring of your location.
A protective order also raises the stakes for the tracker. Under federal law, committing stalking in violation of a protective order carries a mandatory minimum of one year in prison.5Office of the Law Revision Counsel. 18 U.S. Code 2261 – Interstate Domestic Violence
When the Tracking May Actually Be Legal
Not every tracker on a car supports a lawsuit. A few situations create legal authority, or at least a defensible argument, for placing one.
Police can attach a GPS tracker to a vehicle during a criminal investigation, but they generally need a warrant issued by a judge on probable cause. Jones established that attaching a GPS device to a vehicle is a Fourth Amendment search requiring judicial authorization.1Legal Information Institute (LII) at Cornell Law School. United States v. Jones
Employers are generally within their rights to track company-owned vehicles for legitimate business purposes like route management and fleet safety. Several states require written notice to employees before activating GPS tracking on work vehicles. Tracking an employee’s personal vehicle, or monitoring off-duty movements, exposes the employer to the same privacy claims covered above.
Some jurisdictions allow a vehicle co-owner to place a tracker on a shared vehicle, which comes up in divorce and custody disputes. Co-ownership doesn’t override stalking or harassment laws. A co-owner who uses tracking to intimidate, control, or harass the other owner can face criminal charges and civil liability regardless of whose name is on the title.
Some rental car companies install GPS devices in their fleet vehicles. Several states require rental companies to disclose tracking capabilities in the rental agreement and obtain your consent before monitoring for anything beyond theft recovery. Undisclosed tracking may violate state privacy or consumer protection laws.
Private investigators have no special exemption. A PI who physically attaches a tracker to your vehicle without consent faces the same criminal and civil liability as anyone else, and the client who hired the investigator can be held liable too.
