Several products sold by Costco were recalled in June, including power banks, tires and air conditioners. Michelin recalled certain Agilis CrossClimate tires for failing to meet federal standards for tire endurance, according to a Michelin recall notice. Tread rubber may detach from the tire's shoulder block, according to the notice.

Some of the recently recalled power bank models contain potentially faulty lithium-ion battery cells, manufacturer Anker Innovations said.

Costco accepts most returns without time limits, though there are some exceptions. Electronics have a 90-day return window. Cigarettes and alcohol may not be returned where it’s against the law. Airline and live performance event items, ticket items, precious metals, Shop Cards and gift cards are not returnable.
