Is Your Car’s Wi-Fi as Secure as Password123 - That’s a Problem
In the early days of home Wi-Fi, routers came with default network names—something generic like “Linksys123” or “Netgear456.” Many people never changed them, not realizing that sticking with the default settings could make their network vulnerable.
Fast forward to today, and cars have followed a similar path. Many modern vehicles come with built-in Wi-Fi, often with a default SSID that clearly identifies the make or model. Some real-world examples include:
While specific default SSIDs for other brands like BMW and Toyota vary, they typically follow a similar pattern, incorporating the brand name or model. Just like early Linksys routers, these factory-set network names make it easy to connect but are rarely customized by owners.
The problem? If you wouldn’t trust Password123 to secure your home Wi-Fi, why leave your car’s network on factory settings?
From Basic Electronics to Smart Vehicles
For most of automotive history, cars were purely mechanical. The only real “communication” systems were dashboard warning lights and basic diagnostics. But by the late 20th century, technology began reshaping the driving experience.
1996: General Motors introduced OnStar, one of the first telematics systems, allowing drivers to call for roadside assistance via a built-in cellular connection.
Late 1990s: GPS navigation appeared in high-end vehicles, though maps were stored on CDs or DVDs.
Early 2000s: Infotainment systems started making their way into cars, offering screens for navigation and basic digital controls.
2007: The iPhone changed the tech landscape, creating demand for better smartphone integration in vehicles.
2010s: Features like Bluetooth streaming, Apple CarPlay, Android Auto, and built-in Wi-Fi hotspots became standard.
By the mid-2010s, cars had evolved into rolling smart devices, capable of real-time navigation, cloud-based updates, and even remote software fixes. Much like home networks became an essential part of daily life, in-car connectivity became an expectation rather than a luxury.
The Rise of the Rolling Wi-Fi Network
As automakers embraced connectivity, cars started behaving more like home networks. Many new vehicles now have their own SSID (network name) and password, allowing passengers to connect devices just as they would at home.
However, just like early home Wi-Fi networks, most vehicles ship with default network settings—preconfigured names and passwords that many owners never think to change. This may seem harmless, but just as unsecured Wi-Fi can pose risks, leaving your car’s network on factory settings can create vulnerabilities.
Cybersecurity in Connected Cars
Car manufacturers build in security measures, but a little awareness goes a long way in keeping your vehicle safe. A few simple steps can make a big difference:
Change Default Settings – If your car has a built-in Wi-Fi network, change the default SSID and password.
Keep Software Updated – Many modern cars receive over-the-air (OTA) updates that improve security, just like your smartphone.
Review Connectivity Options – Check your vehicle’s settings to control what data it shares and with whom.
Just as people learned to secure their home Wi-Fi networks, drivers should start thinking about their car’s connectivity settings.
What to Consider When Buying a Car
Buying a car today isn’t just about horsepower and design—it’s about understanding the technology inside. When shopping, it’s worth asking:
Does the car have a built-in Wi-Fi hotspot?
Can the default network settings be changed?
How often does the software update?
What security features does the manufacturer provide?
Being aware of these details ensures a safer, smarter driving experience.
Set Your GPS to Savings
The modern car is a mobile smart device, and just like with home networks, a little proactive thinking goes a long way in keeping it secure.
