Modern cars are technological marvels on wheels—smart, connected, and always a few steps ahead of their drivers. While this progress offers convenience, safety, and a touch of luxury, it also hides a surprising reality: many of these high-tech features can be controlled or accessed remotely, often without the driver’s full awareness. In a world where connectivity rules and data flows endlessly between devices, vehicles are no longer mere machines but rolling computers that can be switched on, off, or manipulated with a tap from miles away.
For some, this level of control feels like an innovation; for others, it sparks an uneasy sense of being watched. As more cars plug into the digital grid, it is worth understanding which features might be accessible to others—sometimes without the owner even realizing it.
1. Engine Start and Stop
Remote ignition systems have become one of the most popular modern conveniences for drivers eager to pre-warm or cool their cars. Many car manufacturers now include smartphone apps or fobs that allow the engine to start or shut down with just a signal sent over a network. However, this same system can potentially be accessed by manufacturers, service providers, or even hackers if security measures fail. An unsuspecting driver may never realize someone else has the power to cut the engine while the car is parked—or worse, while it is idling in a driveway. This feature, while practical, reveals just how vulnerable a connected car can be.
2. Door Locks and Unlocks
Gone are the days when unlocking a car required a physical key inserted into a door. Most vehicles today have smart locks that respond to wireless signals from a fob or mobile device. Auto manufacturers, roadside assistance services, and sometimes law enforcement can remotely unlock doors if needed, bypassing any physical barrier. This functionality is undeniably convenient in emergencies or lockouts but raises privacy concerns about who else might gain access. The quiet reality is that the locks on modern cars are as digital as they are mechanical.
3. GPS Tracking
Many modern vehicles come equipped with built-in GPS tracking for navigation, fleet management, or emergency services like stolen car recovery. Owners often sign up for this feature for safety and peace of mind, not realizing that the vehicle’s location can be pinged at any time. Automakers, insurance companies, and even rental agencies have the power to track where a car goes and when it arrives. For some drivers, this level of surveillance can feel intrusive when revealed. Yet it remains an integral part of many connected car systems.
4. In-Car Microphones
Voice command systems have become standard as drivers embrace hands-free technology to send messages, change music, or get directions. What is less obvious is that these in-car microphones can be remotely accessed by manufacturers for diagnostic or customer service purposes. In some cases, law enforcement with the right warrants can also listen in, turning a private cabin into a potential audio surveillance zone. While active eavesdropping is rare, the technology makes it technically possible. Drivers may never suspect that their casual conversations could be heard beyond the dashboard.
5. Cameras and Dashcams
Modern vehicles often come with multiple cameras for parking assistance, lane-keeping, or enhanced security. These cameras can sometimes be activated remotely for software updates or diagnostics. Some luxury car brands even allow owners to view their car’s surroundings via smartphone apps, which means the video feed is accessible via the internet. This level of access, however, creates potential for misuse if hackers or unauthorized parties gain entry. Few drivers think twice about the silent eyes perched on their bumpers or windshields.

6. Infotainment System Access
The sleek touchscreen in a car’s dashboard is more than just an entertainment hub—it is a connected computer with links to apps, calls, messages, and sometimes banking details. Automakers can remotely update or troubleshoot these systems, occasionally accessing them without notifying the owner in real-time. Hackers have demonstrated the ability to breach these systems to control various car functions or gather data. Drivers might assume their infotainment console is just for their enjoyment, but its connectivity makes it a hidden doorway for remote access. Once inside, outsiders can glean surprising amounts of personal information.
7. Climate Control
High-end vehicles often boast climate control systems that can be adjusted remotely for the driver’s comfort. A quick tap on a phone app can warm up the cabin on a freezing morning or cool it down before a scorching afternoon commute. Yet, like other connected features, this control can be exercised by technicians or third parties during maintenance or upgrades. If the system’s security is weak, unauthorized access could disrupt more than just the cabin temperature. Few owners think of their AC or heater as part of the remote network that shapes the modern driving experience.
8. Braking and Steering Assistance
Advanced driver-assistance systems (ADAS) include semi-autonomous braking and steering to help prevent collisions and keep the car in its lane. These systems rely on complex software that can be updated or fine-tuned remotely by the manufacturer. While these updates are generally for safety and performance, they also demonstrate that fundamental aspects of vehicle control can be influenced from afar. There have been documented tests where researchers remotely manipulated steering and braking to expose vulnerabilities. Though these scenarios are rare, they prove that critical driving functions are not entirely beyond remote reach.
9. Over-the-Air Software Updates
What once required a trip to the dealership now happens invisibly over the air. Automakers routinely push software updates to fix bugs, enhance features, or address security gaps without the driver lifting a finger. These updates can modify performance, alter settings, and even disable or enable features overnight. Owners may wake up to find their cars have changed subtly without any clear notification beyond a vague update note. This silent control highlights just how much power remains in the hands of manufacturers long after the car leaves the lot.
10. Speed and Performance Monitoring
Performance monitoring is no longer just for high-end sports cars. Many new vehicles include telematics that track speed, acceleration, and driving habits for insurance discounts or parental controls. These systems can be accessed remotely by insurers, car companies, or fleet managers, sometimes influencing policy rates or usage restrictions. Drivers who think they are off the grid when they hit the gas might be surprised to learn their every burst of speed could be recorded. Remote oversight of performance turns the modern car into a data goldmine on wheels.
The Trade-Off Behind Convenience
Cars today are more connected and capable than ever before, blending high-tech convenience with unseen levels of remote control. For drivers, these features can save time, protect against theft, and keep families safe on the road. Yet they also come with hidden strings, quietly linking vehicles to networks that others can tap into at will. Understanding which parts of a car can be accessed remotely is the first step in protecting privacy and ensuring security. What features did this list make you reconsider?
