Toyota said Monday its dealers should get parts to fix a sticky gas pedal problem by the end of this week as the automaker apologized to customers and tried to bring an end to a recall that has affected 4.2 million vehicles worldwide, according to The Associated Press.

The company said in a statement that it has begun shipping parts and is training dealers on the repairs. Some dealers will stay open around the clock to fix the 2.3 million cars and trucks affected by the recall in the United States.

Technical bulletins on how to install the new parts should arrive at dealers by midweek, the company told dealers in an e-mail. It was not clear exactly when repairs would start, although dealers have said they'll begin as soon as possible.

The automaker also said Monday it would suspend production of eight U.S. models affected by the recall this week, with factories restarting on Feb. 8.
