Nearly 89% of smart device manufacturers fail to disclose how long they will provide software updates for their products, a Federal Trade Commission staff study found this week. The review of 184 connected devices, including hearing aids, security cameras and door locks, revealed that 161 products lacked clear information about software support duration on their websites.

Basic internet searches failed to uncover this information for two-thirds of the devices. “Consumers stand to lose a lot of money if their smart products stop delivering the features they want,” said Samuel Levine, Director of the FTC’s Bureau of Consumer Protection. The agency warned that manufacturers’ failure to provide software update information for warranted products costing over $15 may violate the Magnuson Moss Warranty Act. The FTC also cautioned that companies could violate the FTC Act if they misrepresent product usability periods. The study excluded laptops, personal computers, tablets and automobiles from its review.
