Toyota has announced another recall involving more than one million cars in the US and Canada with potentially faulty engine control systems.

丰田宣布在美国和加拿大再次召回100多万辆轿车，此次召回的车辆可能存在发动机控制系统问题。

The recalls have cast a shadow over Toyota in 2010

The models affected¹ are the Corolla and Matrix made between 2005 and 2008.

The Japanese carmaker said three unconfirmed accidents were "alleged²（宣称，断言） to be related" to the problem, one of which resulted in a "minor³ injury".

Last month, Toyota recalled 700,000 cars worldwide and has now recalled about 10 million in the past year.

The two recalls in July were due to steering⁴（操纵，指挥） and engine problems, while those earlier in the year were because of sticking accelerator pedals（油门踏板） .

Engine failure

The latest recall involves 1.1 million cars sold in the US and Canada.

The problem with what Toyota calls the models' engine control module⁵ may result in a crack in solder⁶ points or on some electronic componentry（元件） .

If a crack appears, the engine may not start or, "in limited instances, the engine could stop while the vehicle is being driven", the carmaker said.

"This recall is an example of our commitment to standing⁷ by our products and being responsive to our customers," said Steve St Angelo, Toyota's chief quality officer for North America.

"Our goal is to help ensure that Toyota drivers are completely confident in the safety and reliability⁸ of their vehicles."

Toyota was harshly（严厉地，刺耳地） criticised for not acting⁹ sooner over the accelerator pedal recalls, and was fined $16m by US authorities.

Recalls in the car industry are common, but the extent of Toyota recalls is unprecedented¹⁰ - the firm has now issued 14 recalls in 2010.
