The Japanese firm said the global recall involved its RAV4 SUV model produced between July 2005 and August 2014.
The fault means there is a possibility that seatbelts could be damaged by a metal seat frame part in the event of a crash.
Toyota said it had received two reports in which rear seatbelts separated following crashes but was unsure whether these incidents were linked to any injuries or fatalities.
Toyota sells about one million cars a year in Europe, with around 10% of those in the UK. That means it is possible more than 40,000 vehicles in Britain may need to be recalled.
Between 2005 and 2014, Toyota sold a total of 78,465 RAV4s to the UK market – equivalent to 7,847 per year.
Despite the recall, Toyota shares advanced 1.7% but they did lose some of their shine having been as much as 3.6% higher at the open.
