The problem identified arises when the cars fail to enter 'failsafe driving mode as intended'. In this mode, the car's speed is limited at 30-45MPH, which prevents further damage to the engine but allows the driver to vacate the road.
While these cars were created to enter this mode in response to certain hybrid system faults, this may not operate as intended. The carmaker stated that no actual accidents have been recorded so far.
Approximately 290,000 of the affected vehicles have been sold in Europe with the majority being purchased in Japan and North America during the six-year period. If that happens at higher speeds, there is an increased risk of a crash.
The automaker said that it was not aware of any crashes due to the issue in Japan.
Toyota Australia said it would contact all affected auto owners to advise them to book into a Toyota dealer to have the software fixed free of charge.
Should this occur, the vehicle could lose power and stall, although functions such as the power steering, brakes and lights would still work.More news: The Los Angeles Dodgers will win the NL Pennant - here’s why
Toyota Ireland also said that there are no reported incidents in Ireland.

Separately, Toyota on Friday also announced a recall covering certain 2018 to 2019 Tundra pickup trucks and Sequoia SUVs, as well as 2019 Avalon cars, to fix an airbag defect.
A UK Toyota spokesman told Express.co.uk the company would contact all affected auto owners in due course after retrieving owner information from the Driver and Vehicle Standards Agency (DVSA).
The process should take about 40 minutes on average.
It's one of the largest recalls for Toyota unrelated to Takata Corp airbags or 2009's unintended acceleration crisis.
