How to Tell If Your Vehicle Has a GPS Tracker

If you suspect someone is tracking your vehicle, don’t ignore it. GPS trackers are used in auto theft targeting, domestic surveillance situations, and corporate disputes. The good news: there are clear signs and safe next steps.

Common signs your vehicle may be tracked

  • Unusual behavior from someone who shouldn’t know your schedule (showing up “randomly” in the same places)
  • Strange battery drain (some trackers are hardwired or plug into OBD ports)
  • New noises or loose trim after a service or unknown access
  • Evidence of tampering near the undercarriage, wheel wells, bumpers, or OBD-II port

Where GPS trackers are commonly hidden

Most trackers are placed for speed and concealment. Common locations include:

  • Undercarriage (magnetic trackers attached to metal)
  • Inside bumpers or behind plastic trim
  • Wheel wells or splash guards
  • OBD-II port under the dashboard (plug-in trackers)
  • Behind interior panels or glove box areas

Do NOT do this

  • Don’t rip parts off or start tearing down panels (you could destroy evidence)
  • Don’t “test” suspicious devices by powering them on
  • Don’t confront anyone if you suspect a real threat

Safe steps you can take right now

  1. Visually inspect under the vehicle with a flashlight (don’t crawl under if unsafe).
  2. Check the OBD-II port for a device plugged in that you didn’t install.
  3. Document anything suspicious with photos/video and the date/time.
  4. Call a professional sweep if you want certainty and proper documentation.

When you need a professional vehicle sweep

If you’re a high-risk target (legal dispute, custody/divorce, executive, or high-theft vehicle), a professional sweep is the fastest way to confirm what’s happening. A proper inspection includes magnetometer scanning, RF detection, interior/trim inspection, and evidence handling.
