Due to a latent defect, Toyota's chrome lug nuts swell such that the lug wrench no longer fits the nuts. Owners confronted with flat tires are stranded on roadsides, potentially out of cell phone range, because they are unable to change the tire. I personally was stranded at midnight due to this defect. I alerted my Toyota dealership in Peoria, Illinois. They said they were aware of the issue on Sequoias and Sienas and that the could not keep enough lug nuts in stock. Toyota has provided no formal notice to owners of this latent defect and safety hazard. Both the Toyota dealership and Toyota care refused to provide without charge replacement lug nuts.
