How over-the-air (OTA) updates are changing car ownership

What are over-the-air updates?

Over-the-air updates allow car manufacturers to send new software directly to a vehicle using a wireless internet connection. These updates can include everything from minor bug fixes and infotainment improvements to significant changes in safety features, battery management and even performance.

Previously, updating your car’s software usually meant booking a service appointment and leaving your vehicle at the dealership. With OTA technology, updates can happen overnight while your car is parked at home. You can literally wake up to a vehicle that has new features or improved functionality without lifting a finger.

What cars offer OTA updates?

OTA updates were first made popular by Tesla, but the technology has now spread across the automotive industry, particularly with the rise of electric vehicles (EVs). Many manufacturers selling cars in Australia now offer some level of OTA capability, including major brands like BMW, Mercedes-Benz, Hyundai, Kia, Ford, Volkswagen and more.

The scope of what can be updated varies between brands and models. Some vehicles only receive OTA updates for maps and infotainment systems, while others can have their safety systems, driver assistance features and powertrain software updated remotely. If you’re in the market for a new car, it’s worth doing some research and asking the dealership exactly what OTA updates cover for that model.

Benefits for Australian drivers

OTA updates bring several advantages that make car ownership more convenient and potentially safer.

Convenience

There’s no longer the need to schedule a time-consuming trip to the dealership service department for many software related improvements. Updates can install automatically when your car is connected to Wi-Fi or mobile data.

Faster safety fixes

If a manufacturer identifies a software related safety issue, they can push a fix to affected vehicles quickly rather than waiting for owners to bring their cars in.

Improved features over time

Your car can gain new capabilities months or years after you bought it. Some EV owners have seen improvements to their vehicle’s range, while other models have received performance or driver assistance systems through OTA updates.

Reduced recall hassle

Software related recalls can often be resolved remotely, saving you time and reducing inconvenience.

For drivers in Sydney and across Australia, this means less time off the road and more confidence that your vehicle is running the latest and safest software available.

Things to keep in mind

While OTA updates offer plenty of benefits, there are a few considerations worth noting.

Internet connectivity

Your car needs a reliable internet connection to download updates. Some updates require Wi-Fi due to their size, while smaller patches may work over mobile data.

Update timing

Most systems let you schedule when updates install, but it is important to ensure your car is parked safely, and if an EV, has enough battery charge during the process.

Understanding what changed

Manufacturers usually provide release notes explaining what each update includes. It is a good idea to review these, so you know what has changed in your vehicle.

Not everything is OTA

Hardware issues, wear and tear, and many mechanical components still require hands-on servicing from a qualified mechanic like Leondis Automotive. OTA updates handle software, but your car still needs regular maintenance to stay safe and reliable.

How OTA updates work alongside regular servicing

OTA technology is impressive, but it does not replace the need for professional mechanical care. Your brakes, tyres, suspension, filters and fluids all require physical inspection and maintenance that no software update can provide.

Think of OTA updates as one part of keeping your car in top condition. They handle the digital side, while regular servicing takes care of the mechanical and safety critical components. Together, they help ensure your vehicle performs at its best and stays safe on the road.

Modern vehicles also rely on complex electronics and sensors that need expert diagnostics when something goes wrong. A workshop equipped with up-to-date diagnostic tools can identify issues that may not trigger a warning light but could still affect your driving experience or safety.
