Toyota says its U.S. sales fell 16 percent in January as the Japanese automaker halted sales of its most popular vehicles during the final week of the month.

Other automakers have been reporting stronger January sales compared with a year ago, when sales fell to a 26-year low. But worries about faulty gas pedals forced Toyota last week to suspend sales of eight models, including top-sellers like the Camry, the Corolla and the RAV4.

Toyota has recalled 2.3 million of the vehicles in the U.S. and on Monday stopped production of the affected models. It has begun shipping a fix to dealers and will resume selling the affected vehicles once dealers install the repair to vehicles on their lots. It will resume production next week.
