Toyota has told dealers in the U.S. to stop selling six of its popular vehicles with heated seats because the "fabric doesn't comply" with current U.S. safety codes and could catch fire, according to the Associated Press.

The automaker has stopped selling 2013-14 Camry and Corolla models with heated seats, along with vehicles like the Avalon, Sienna, Tacoma, and Tundra.

Toyota said it is still trying to figure out how many vehicles affected by the issue were sold in the U.S.

Approximately 36,000 vehicles are affected by the issue, or 13 percent of all Toyota vehicles at U.S. dealerships.

Currently, Toyota isn't sure when sales for the affected vehicles will resume again.

"We're assembling some parts now, and will start remedying vehicles in dealer lots in the near future," said Toyota spokesman Brian Lyons in a statement, according to CNN.

The automaker said some of the materials used in its seats don't meet regulatory standards for flammability.

Toyota is hoping to avoid a recall, saying that the fault is "not a motor vehicle safety issue," according to CNN.

"Hopefully we'll get some parts in where we can get them fixed by the end of February," said Earl Stewart, owner of a dealership in North Palm Beach, Florida, according to AP.

The National Highway Traffic Safety Administration said it will "consider" the automaker's petition to avoid a recall.

The Camry was the top-selling vehicle in the U.S. last year with over 408,000 vehicle sales in 2013.
