Toyota is having to recall more than 45,000 cars after noticing a defect with the vehicles' seat belts.
A Toyota UK spokesman said that the fault applied to all 2006 and 2007 Yaris models and owners will receive letters explaining the problem and the action required by the customer.
The problem lies with the car's seat belt pretensioner, which is a safety measure locking a seat belt in place when there is a collision. The spokesman said it could heat up, causing a fire in a high speed head-on crash.
Although there have not been any reported cases of this happening, the company is taking the precaution of recalling the vehicles.
The spokesman added: "We can use chassis numbers to identify the cars involved and then trace the owners through the DVLA to ensure the right people are sent letters."
