Miles is entering the connected-car market with a small plug and a large promise: drivers can monitor where a vehicle goes, how it is driven and whether it needs attention without turning those details into a product for advertisers or data brokers.
The Miles Plug, which connects to a vehicle’s OBD-II diagnostic port, is presented as a subscription-backed alternative to tracking tools supplied by automakers, insurers and app makers. It uses cellular and GPS connections to send location, trip and driving information to an accompanying app. Its stated audience includes parents of new drivers, but the pitch reaches further: owners of older cars who want digital vehicle information without relying on a manufacturer’s connected service.
That combination makes the product’s privacy terms as important as its hardware. Miles cofounder Matt McGovren says the company will not sell vehicle, trip or location data, and says its app carries no advertising. Those are company representations, rather than independently verified findings, but they address a persistent concern around connected vehicles: data that can reveal not only where a car has been, but also patterns of life, driving behavior and maintenance needs.
A diagnostic-port device built around ongoing connectivity
The plug sits in the OBD-II port found in many vehicles, a connector commonly used for diagnostics. Miles says its device is compatible with most gasoline and hybrid cars from model year 2008 onward, along with some electric vehicles. That description is qualified by the company’s own compatibility checker, meaning prospective buyers would still need to confirm support for a particular make and model before assuming it will work.
Once connected, the device is meant to identify the vehicle and transmit information through the app. The reported feature set includes current or recent location, trip records, alerts tied to driving behavior and vehicle-health information. The app can log routes, distance, trip time and a driver identifier. It can also notify users when a car arrives at or leaves home, while alerts can flag events such as hard acceleration and hard braking.
Unlike phone-based family location sharing, Miles describes its tracking as connected to the vehicle, not the driver’s handset. The practical consequence is that the system is meant to stop tracking the person once they leave the car. That distinction could matter to families seeking information about a shared vehicle while trying to avoid continuous monitoring of an individual’s movements away from it. It does not, however, reduce the sensitivity of the vehicle’s own location history when it is in use.
The company says users can download their information, disable location collection and delete their account and associated data. McGovren has also said that vehicle and trip data are encrypted, with the most sensitive data end-to-end encrypted. The supplied information does not set out the technical design in enough detail to assess how those controls operate in every circumstance, how deletion is implemented, or what information may be necessary to retain for the service to function.
A short hands-on test found core alerts working
In a brief test described by The Verge, the device was installed in a 2014 Toyota Highlander. The reviewer reported an uncomplicated setup process, said the plug read the vehicle identification number and correctly recognized the car, and found the app straightforward to navigate. Over a couple of days, the system recorded trips and delivered arrival and departure notifications.
The test also generated alerts for hard acceleration and hard braking. Such notices are central to the device’s appeal for parents of less-experienced drivers, since they turn driving events into a shared record rather than relying on a parent’s impression after the fact. But the same feature can create a tension the product is explicitly trying to manage. A service designed to offer reassurance can also become a surveillance tool if drivers feel that every journey is being judged.
Miles’ answer is a shared-account model in which family members can use the app and each driver has a separate profile and alerts. The company’s stated intent is for parents and teenagers to see the same trips and notifications rather than creating hidden layers of monitoring. Whether that arrangement feels collaborative will depend on household rules and on how precisely the service attributes a trip when more than one phone is near the vehicle. The initial reviewer had not yet tested the product with a second driver.
The reported app also includes Miles Mechanic, an AI-based assistant intended to interpret dashboard warning lights, describe the urgency of a potential repair and estimate repair costs. In the limited hands-on use, the assistant answered questions in plain language about the test vehicle’s condition and upcoming maintenance. That could make vehicle data more understandable for drivers who do not routinely interpret warning indicators or maintenance schedules. It is not a substitute for a repair diagnosis, and the available account does not establish the accuracy of its repair assessments or cost estimates across different faults and vehicles.
Help is part of the pitch, but the operating details are thin
Miles lists crash detection or emergency accident response and roadside assistance among the product’s services. These features are likely to be among the strongest reasons a buyer would consider a subscription rather than a basic diagnostic reader: they suggest that the plug is not merely collecting information but could connect a driver to assistance when something goes wrong.
Yet the available reporting does not document an actual crash-detection, emergency-response or roadside-assistance test. Nor does it specify the terms under which help is dispatched, the response process, coverage limits, exclusions or the circumstances in which an alert might fail to result in assistance. The product can therefore be described as offering those stated features, but not as having demonstrated emergency help in the reported test.
There are similar limits around the hardware’s long-term operation. The reviewer said the device had not been in use long enough to assess whether it affects the vehicle’s battery. McGovren said the plug sleeps when the car is inactive, waking periodically to synchronize, and said that use should not materially affect the battery. He also advised removing it if the vehicle will not be driven for an extended period. That is useful guidance, but it remains a company assertion pending longer-term testing in different cars and conditions.
Miles has also discussed a future connection to broader home or AI systems through an MCP server that was described as being in beta. The proposition is that owners could make their car’s information available to an AI or home assistant of their choice, asking questions about fuel level or maintenance. No launch integration was evaluated in the reported hands-on account, so it should be treated as a planned capability rather than a tested part of the service.
The membership price is also the company’s durability argument
Miles says the plug costs $99 and that a one-year membership costs an additional $180, for $279 upfront. It also offers a three-year package, including the plug, for $396 upfront. The company says plans do not renew automatically, and it offers a 60-day money-back guarantee.
The figures translate to $15 a month for the one-year arrangement and roughly $11 a month over three years. The source presents those monthly amounts as shorthand for upfront plans, rather than separate monthly billing. It does not explain whether taxes, discounts or other charges can affect a buyer’s final total, so the stated monthly rates should be read as approximate comparisons rather than a complete account of checkout pricing.
McGovren’s broader argument for charging a membership fee is that cellular connectivity, tracking, assistance and related services need a funding model from the start. The supplied context contrasts that approach with Automatic, a prior OBD-II service that offered tracking, mileage and crash monitoring but later shut down. Miles’ founders previously worked at Wink, another connected-device company that suffered outages, bankruptcy and a sale. Their past experience does not guarantee longevity for Miles, but it informs the company’s case that upfront membership revenue is intended to support the service.
For consumers, this is the central trade-off. The plug is not simply a $99 accessory: meaningful use depends on a prepaid service plan. A buyer must decide whether the value of tracking, alerts, vehicle information, roadside support and the company’s claimed privacy posture justifies that continuing relationship. The three-year plan lowers the implied monthly cost, while also asking customers to pay further ahead for a young service’s future operation.
Privacy claims deserve scrutiny alongside the convenience
Miles is arriving in a category where confidence hinges on both engineering and governance. Location and driving records can help families coordinate, reveal risky driving patterns and make an older vehicle easier to understand. They can also expose sensitive routines. A promise not to sell that information is therefore consequential, especially when it is paired with controls to stop collection, export data or erase an account.
Still, the available account offers only a short test of the basic app experience and the company’s own descriptions of its policies and service design. It does not independently verify the company’s data practices, encryption claims, compatibility across the stated vehicle range, battery performance, AI repair guidance, second-driver behavior or emergency and roadside response. The report has not been independently corroborated.
That uncertainty does not negate the early results: the reviewer reported that vehicle identification, trip logging and several notifications worked in one car over a short period. But it leaves the more consequential questions open. Buyers considering Miles for a teen driver, a shared family car or an older vehicle would be relying on a product whose most important promises—privacy, durability and help in an emergency—extend beyond what the available test establishes.

Reporting notes
What is confirmed: Miles says its plug supports many 2008-and-later gasoline and hybrid vehicles and some EVs. It says users can control, export and delete data.
Why this matters: The service asks consumers to trust a young company with sensitive driving and location data while promising not to sell it.
What remains unclear: Emergency-response performance, roadside-assistance terms, battery impact, data-practice implementation and multi-driver behavior were not independently tested. This report is based on one source and has not been independently corroborated.
