Over-the-air (OTA) updates allow vehicles to receive new software without visiting a dealership. They can fix problems, improve existing systems and add features, but they may also leave a vehicle temporarily unavailable if the process starts at an inconvenient time.
The first step is to check the message displayed on the multimedia system. If the car is only offering the update and allows it to be postponed, drivers who need to use the vehicle soon should choose that option.
If the installation has already started, the vehicle should remain parked while the instructions on the screen are followed. Drivers should not attempt to drive away, disconnect the battery or stop the process by force, as doing so may cause software failures.
The Hyundai Kona’s manual states that an update can be postponed before installation begins. Once the process has started, it cannot be canceled, and the vehicle cannot be used until the installation is complete.
For the Leapmotor C10 REEV, the instructions call for the vehicle to be in Park, with the parking brake engaged and at least 20% battery charge. Some functions become unavailable during installation, and the car cannot be driven. If the vehicle does not return to normal operation after a failure, the manual recommends contacting an authorized dealership.
