LOS ANGELES – Toyota Motor Corp. is temporarily halting sales and production of eight models, including the top-selling Camry and Corolla, that it has recalled because the accelerator pedal can stick and cause unwanted acceleration.

The automaker announced the recall of 2.3 million cars and trucks late last week. That came just months after Toyota launched its largest-ever recall because floor mats could trap the gas pedal and also cause sudden acceleration.

Tuesday, Toyota informed its roughly 1,200 U.S. dealers to immediately halt sales of both new and used models of the affected vehicles: the 2009 to 2010 RAV4, 2009 to 2010 Corolla, 2009 to 2010 Matrix, 2005 to 2010 Avalon, 2010 Highlander, 2007 to 2010 Tundra and 2008 to 2010 Sequoia. It also is halting sales of certain 2007 to 2010 Camry sedans, depending on where those vehicles were manufactured.

Toyota also said it would stop production of those models on assembly lines in Indiana, Kentucky, Texas and Canada, effective Monday.

The automaker did not say how long it would freeze sales of those vehicles, which represent the majority of its sales, by volume, in the U.S.

“At this point, we don’t know,” Toyota spokesman Brian Lyons said about a remedy for the problem. He said that Toyota had never before issued a “stop sale” order. “I’m not going to speculate on how long this will be in effect.”

Aaron Bragman, an auto analyst for the consulting firm IHS Global Insight in Troy, Mich., said Toyota typically sells about 65,000 Camrys and Corollas per month, and the suspension of sales could strike the company’s bottom line and reputation for quality.

“That’s huge if they can’t sell these and they don’t have a fix identified. They need to go and get a solution to this fast,” Bragman said.

The auto company said the sales suspension would not affect Lexus or Scion vehicles. Toyota said the Prius, Tacoma, Sienna, Venza, Solara, Yaris, 4Runner, FJ Cruiser, Land Cruiser and select Camry models, including all Camry hybrids, would remain for sale.
