Toyota is in hot water, having to stop sale of various models, including the Avalon hybrid and Camry hybrid, because of an issue with flammability of seat fabric on seat heaters equipped models.

Toyota said it has informed the National Highway Traffic Safety Administration (NHTSA) that it has initiated a stop sale of Avalon, Avalon Hybrid, Camry, Camry Hybrid, Corolla, Sienna, Tacoma and Tundra vehicles equipped with seat heaters in order to address a non-compliance issue.

Toyota explained on involved vehicles, the seat heater, which is a small portion of the soft materials of the seat assembly, does not meet a provision of U.S. Federal Motor Vehicle Safety Standards (FMVSS) requiring materials to retard flame at a specified rate. Toyota is preparing a modification for this condition, which will be implemented on all covered vehicles in dealer inventory.

According to the company, there have been no reports globally of any related incidents in the field with units in operation. Per NHTSA regulations, Toyota will file a Non-Compliance Information Report.

Toyota added it is still tabulating the exact number of vehicles affected.
