Mr Toyota offered an apology to all current Toyota customers. The recall now spans some 4.2 million vehicles worldwide.
“I am deeply sorry,” said Mr Toyoda, the grandson of Toyota's founder.
The recall has caused the suspension of Toyota sales in some markets and has seen the Japanese giant now halt production of eight models.
Mr Toyoda said it was unclear when the ultimate solution for the recall would be available to customers and dealers, but did his best to reassure Toyota drivers that his company was 'still investigating' a viable fix.
When asked how the recall might affect Toyota’s reputation for quality, Mr Toyoda responded with “I would like for the people to trust us.”
Toyota has yet to officially address the public on the topic of the latest recall.
