A genuinely "connected" car in 2026 typically includes an embedded cellular data connection (not just phone mirroring), over-the-air (OTA) software updates that can improve features after purchase, a companion smartphone app for remote lock/start/status checks, and in many cases subscription-based services for navigation, Wi-Fi hotspot, or advanced driver-assist features after an included trial period. The key things to check before buying are which features require an ongoing paid subscription after the first year or two, and whether the automaker has a track record of pushing meaningful OTA updates rather than just security patches.
At a glance
| Connected feature | What to check before buying |
|---|---|
| Embedded data connection | Confirm how many years of free connectivity are included before a paid plan is required |
| Over-the-air (OTA) updates | Check whether updates are limited to infotainment or can also improve powertrain/features |
| Companion app | Test remote lock/start/locate features and check app store reviews for reliability |
| Subscription services | Identify which features (nav, Wi-Fi, ADAS extras) require ongoing payment after any trial |
| Data privacy disclosures | Review what driving/location data is collected and how it's used or shared |
Connected doesn't just mean CarPlay
Phone mirroring like Apple CarPlay and Android Auto is now standard on most new cars, but that's a different feature from a truly "connected" car, which has its own embedded cellular connection independent of your phone. This built-in connectivity enables features phone mirroring can't: automatic crash notification, remote start/lock via an app from anywhere, live traffic and software updates pushed directly to the car, and in some cases, diagnostics sent automatically to your dealer.
Over-the-air updates: what to actually expect
Some automakers can push meaningful feature updates or bug fixes to a car's infotainment, and in a smaller number of cases, powertrain or driver-assist software, without a dealer visit. Others limit OTA updates to minor infotainment map or security patches. Since this capability varies significantly by automaker and even by model year within the same brand, it's worth researching a specific automaker's actual OTA track record rather than assuming all "connected" cars behave the same way.
Companion apps and remote features
Most connected cars pair with a smartphone app offering remote lock/unlock, remote start, vehicle location, fuel/charge level, and maintenance alerts. App quality varies significantly — some are fast and reliable, others are slow or plagued by server outages during high-demand periods. Checking recent app-store reviews for the specific automaker's app is a practical way to gauge real-world reliability before buying.
Subscription costs to watch for
Many automakers include connected services free for an initial period — often one to three years — after which certain features (navigation with live traffic, in-car Wi-Fi hotspot, remote start, or advanced driver-assist packages) can require a paid ongoing subscription. This is a real, recurring cost that's easy to overlook at the point of sale, so ask specifically what happens to which features after the included trial expires.
Some subscription features are tied to the car, not the original owner — meaning if you buy the car used, you may need to re-subscribe or the previous owner's account may need to be transferred before certain features work. Confirm this before buying a used connected car.
Data and privacy considerations
Connected cars generally collect data on location, driving behavior, and vehicle diagnostics, some of which may be shared with third parties (insurers, marketers) depending on the automaker's privacy policy and your account settings. Reviewing the privacy disclosure and adjusting data-sharing settings in the companion app is a reasonable step for privacy-conscious buyers.
