Japanese automotive giant Toyota is due to recall 1.9 million Prius vehicles globally due to potential problems with the hybrid system's boost converter software that could lead to a lack of power or cause the car to stop completely.
Recalls involve 30,790 UK-registered Prius models manufactured between March 2009 and February 2014 and affected owners will be notified via a letter from the marque outlining the repair process.
A Toyota spokesperson said: "In limited cases, the hybrid system might shut down and the vehicle will stop, perhaps while being driven.
"The car may stop while driving, but not suddenly. It would slow down, eventually to stop."
"All the vehicles affected by this issue are being recalled so that the control software can be updated," a statement read on the company's UK blog.
Vehicle owners will be contacted by Toyota within the coming weeks by post or telephone and asked to make an appointment to bring their car to their nearest Toyota centre, in accordance with Vehicle and Operator Services Agency (VOSA) guidelines.
A Toyota spokesperson said in a statement: "The software update will take about 40 minutes to complete; the work will be carried out free of charge."
The latest recall joins a long list of defects that has plagued the brand over recent years. Toyota share prices fell considerably when 10 million vehicles were recalled in 2010 due to acceleration issues.
Despite this, Toyota remained the top-selling global car maker last year, with worldwide deliveries amounting to almost 10 million vehicles.
