Cars have become increasingly connected. Modern vehicles can communicate with smartphones, cloud services, navigation systems and other devices, while many also rely on software to manage important functions. This technology brings convenience, but it also creates a new question for drivers: can your car be hacked through car hacking techniques??
The answer is yes, connected vehicles can face cybersecurity risks. However, that does not mean every modern car is easy to hack or that drivers should be constantly worried. Automakers are investing heavily in vehicle cybersecurity, while regulations, security standards and software updates are becoming increasingly important.
In 2026, car hacking is no longer simply a futuristic idea. It is an important consideration as vehicles become more connected and software-driven.
How Can a Car Be Hacked?
A modern vehicle can contain numerous electronic control units, communication networks, sensors and wireless connections. These systems need to work together to operate different parts of the vehicle.
Potential entry points can include connected infotainment systems, Bluetooth connections, mobile applications, telematics services, wireless networks and other communication interfaces.
The important point is that an attacker does not necessarily need physical access to every part of a vehicle. Depending on the vehicle’s design and security protections, vulnerabilities in a connected system could potentially provide a path towards other vehicle functions.
The U.S. National Highway Traffic Safety Administration describes automotive cybersecurity as protecting vehicle electronic systems, communication networks, software, data and other components from malicious attacks, unauthorised access or manipulation.
Why Are Modern Cars More Exposed?
Older vehicles were largely mechanical and had fewer connections to external networks. Modern cars are different.
Connected services allow vehicles to perform functions remotely, receive information and communicate with external systems. Software-defined vehicles can also receive over-the-air updates, allowing manufacturers to fix problems or improve features without requiring a workshop visit.
These capabilities are useful, but every additional connection has to be properly secured.
The automotive industry is therefore dealing with a larger cybersecurity landscape involving the vehicle itself, mobile applications, cloud platforms, suppliers and software updates.
What Could Happen During a Cyberattack?
The consequences depend on what system is affected.
A cybersecurity incident might involve access to personal information, disruption of connected services or interference with infotainment functions. In more serious situations, vulnerabilities involving vehicle control systems could create safety concerns.
This is why vehicle cybersecurity is not simply about protecting someone’s music settings or navigation history. Cybersecurity can also become a safety issue when digital systems are connected to functions that influence how a vehicle operates.
NHTSA specifically focuses on ensuring that vehicle systems work as intended and are designed to mitigate cybersecurity-related safety risks.
Keyless Entry Is Another Area to Watch
Wireless key systems have made getting into a car much more convenient. Drivers can often unlock and start their vehicles without taking the key out of their pocket.
However, wireless systems can introduce additional security considerations. Criminals may attempt to exploit weaknesses in keyless entry systems using techniques designed to interfere with communication between the vehicle and its key.
This does not mean keyless systems are inherently unsafe. Manufacturers use different security technologies to protect them, and vehicle owners can take simple precautions such as keeping keys away from easily accessible exterior locations at home.
Over-the-Air Updates Bring Benefits and Risks
Software updates are becoming a normal part of vehicle ownership. Manufacturers can use over-the-air updates to fix software problems, improve functionality and address security vulnerabilities.
At the same time, the update process itself needs strong protection.
A recent 2026 discussion from Tata Motors Passenger Vehicles highlighted the importance of secure boot, code signing, hardware-based trust and ongoing monitoring when vehicles support OTA updates.
This illustrates an important principle: the more software-dependent a vehicle becomes, the more important secure software management becomes.
Can Electric Vehicles Be Hacked?
Electric vehicles are not automatically more vulnerable simply because they are electric.
However, EVs often rely extensively on software and electronic systems for battery management, charging, energy consumption, connectivity and other functions. This makes cybersecurity an important part of EV development.
Connected charging systems can also introduce additional communication points between the vehicle, charger, network and other digital services.
As EV adoption increases, manufacturers need to consider cybersecurity across the entire ecosystem rather than focusing only on the vehicle itself.
What About AI and Autonomous Driving?
Artificial intelligence and advanced driver-assistance systems are adding another layer to vehicle cybersecurity.
Modern systems can use cameras, radar, sensors and software to understand what is happening around the vehicle. If these systems are compromised or manipulated, the consequences could potentially be more serious than a simple infotainment failure.
Research published in 2026 has also highlighted emerging security concerns around AI systems used in self-driving vehicles, demonstrating why cybersecurity is becoming increasingly connected to automated driving safety.
As autonomous technology develops, manufacturers will need to protect not only vehicle networks but also the data and algorithms used to make driving decisions.
How Can Drivers Reduce the Risk?
Drivers cannot control every aspect of vehicle cybersecurity, but they can take some sensible precautions.
Keep vehicle software updated: Install manufacturer-approved updates when they become available. Security patches may address vulnerabilities as well as improve vehicle functions.
Protect connected accounts: Use strong, unique passwords for vehicle apps and associated accounts. Enable additional security measures when available.
Be careful with third-party devices: Avoid connecting unknown or untrusted devices to the vehicle.
Secure your key fob: If you own a keyless vehicle, consider storing the key in a location that reduces the possibility of unauthorised wireless communication.
Watch for unusual behaviour: Unexpected changes in connected services, vehicle apps or electronic functions should not simply be ignored.
Use authorised service providers: Software and electronic systems should be diagnosed and updated using appropriate equipment and manufacturer-approved procedures.
Is Car Hacking a Major Risk for Every Driver?
Not necessarily.
The existence of cybersecurity vulnerabilities does not mean that every connected vehicle is likely to be hacked. Modern manufacturers invest in multiple layers of protection, including secure communications, authentication, software controls and monitoring.
The bigger issue is that cybersecurity must evolve alongside vehicle technology.
As cars become more connected, manufacturers have to continuously identify vulnerabilities, test systems and respond to newly discovered threats. In 2026, cybersecurity is increasingly being treated as a core part of vehicle engineering rather than an optional feature.
The Future of Vehicle Cybersecurity
The future car will likely contain even more software, connectivity and automation. That means cybersecurity will become increasingly important.
Vehicle manufacturers, technology suppliers and regulators are working to address these challenges through security standards, testing, monitoring and software updates. Industry discussions in 2026 are increasingly focused on securing software-defined and AI-enabled vehicles as these technologies become more widespread.
For drivers, the biggest change is awareness. Buying a technologically advanced vehicle also means understanding that its digital systems need protection and maintenance.
Final Thoughts
So, can your car be hacked? In theory, connected vehicles can be exposed to cybersecurity vulnerabilities, just like other connected technologies. But manufacturers are continuously developing security measures to reduce these risks.
The rise of car hacking concerns is closely linked to the rapid growth of connected, software-defined and increasingly automated vehicles.
For drivers, keeping software updated, protecting connected accounts and paying attention to unusual electronic behaviour are simple steps that can improve security. As cars become more like computers on wheels, cybersecurity will become just as important to vehicle ownership as traditional maintenance.
