After months of thefts that have led to at least eight deaths, car makers Hyundai and Kia are offering free software updates to roughly 8.3 million cars that can be stolen with the aid of a USB-A cable.

The National Highway Traffic Safety Administration said Tuesday that the manufacturers' updates make it so affected cars require a key to be in the ignition switch to start. The cars' no-key alarms will also sound for one minute instead of 30 seconds. The updates should start arriving later this month, with phased rollouts over subsequent months for 3.8 million Hyundais and 4.5 million Kias.

According to news reports and at least one class-action lawsuit, the most-affected vehicles are Kias made between 2010 and 2021 and Hyundais produced between 2015 and 2021. Thieves typically break a back window to avoid alarms, expose the steering column, and fit a USB-A cable into a matching plug. Turning the plug with an inserted cable starts the car because the cars lack an engine immobilizer that prevents the engine from starting without a paired key.
