"Toyota will implement a recall in Europe for this matter," the automaker's United Kingdom office said in a statement.
Toyota has not specified just which or how many European-market models will be affected, although it said that a "running change in production using different parts has already been implemented model-by-model in the European production."
"We want to get the message out that there will be a recall but data is still being collated as to which exact models and exact number of cars," a spokesman told London's The Times.
