A car owner says a routine car dealership visit took a disturbing turn after their phone began sending repeated alerts: “Unknown Hey Tag detected with you.”
In a Reddit post shared by user Infinite-Ad-5576, the driver detailed how they ultimately discovered not one, but two tracking devices magnetically attached to the inside of their rear bumper after picking up their vehicle from a dealership service appointment.
“Hello, I found two trackers on my vehicle yesterday. They are different types and were right next to each other, attached with magnets to the inside of the rear bumper,” the Redditor wrote.
According to the post, the driver’s phone showed they were tracked throughout a road trip, matching the exact times the vehicle was driven and then parked for the night.
“The next day (Sunday), I was tracked starting at 5:46 am, exactly when I started driving the car and ended when I removed the battery from the smaller one after I tapped the ‘play sound’ on my phone and located it while it was audibly chirping,” they wrote.
What is a Hey Tag?
A Hey Tag is a small Bluetooth-enabled tracking device similar to Apple’s AirTag. These devices connect to nearby smartphones to relay location data to their owners. Modern smartphones can detect unfamiliar tracking devices traveling with a user and issue safety alerts, such as the “Unknown Hey Tag detected” notification the Redditor received.
Unlike more advanced GPS trackers, which can transmit data directly to cellular networks through subscription services, Bluetooth-based tags rely on proximity to phones to update their location. The Redditor said the smaller Hey Tag was distinct from a second, larger device they found mounted beside it.
“From the research I’ve done, it seems the larger one has the potential to send information directly to a cell tower with the owner having a subscription of sorts,” they wrote. They added that the larger device briefly blinked green while they were driving at night and had no visible way to power it down.
The driver admitted they initially ignored the warnings because they use tracking tags in company vehicles at work and had grown accustomed to dismissing such notifications.
Timeline concerns
The vehicle had been out of the owner’s possession from Monday through Friday while at the dealership for servicing ahead of a planned 1,200-mile weekend trip. The car was reportedly parked in an unsecured lot during that time.
They drove straight home after picking up the vehicle Friday evening and began their road trip Saturday morning, when the tracking alerts started appearing. Infinite-Ad-5576 said the dealership told them the tracking devices were not theirs.
Commenters on the thread urged immediate caution. One warned the situation could be linked to burglary planning, suggesting the driver may have mentioned their travel plans at the dealership. The commenter advised setting up home security immediately, especially if the trip was ongoing.
Another speculated that someone at the dealership — or someone who overheard conversations there — could have planted the trackers to monitor when the home would be vacant. They encouraged contacting law enforcement, noting that dealerships have customers’ home addresses. “Sounds like some amateur burglary operation,” one commenter wrote.
The Redditor said they have already contacted the police and provided all relevant information. “I have a very small circle and no known stalkers at this time,” they wrote, adding that they have many unanswered questions about who placed the devices and why.
