WASHINGTON — Toyota suspended U.S. sales of some of its most popular vehicles — including the best-selling car in America, the Camry — to fix sticking gas pedals that could make the cars accelerate without warning.

In another blow to the world’s No. 1 automaker, Toyota Motor Co. said Tuesday it would halt some production at five assembly plants beginning the week of Feb. 1 “to assess and coordinate activities.”

The company said it would stop selling eight models of cars and trucks, a significant portion its fleet. The suspension comes after Toyota recalled the same models last week, involving 2.3 million vehicles.
