Ninja Foodi Blender Lawsuit Claims Defective Device Caused Serious Injuries

Lawsuit cites a prior CPSC blender recall that linked loose blades in a similar Ninja model to at least 53 laceration injuries.

A Colorado man has filed a lawsuit claiming that certain Ninja Foodi Power Blender & Processor Systems have a defective design, which caused him to suffer severe lacerations to his fingers.

The complaint (PDF) was brought by Scott Evan Jacobsen in the U.S. District Court for Colorado on December 10, naming SharkNinja Operating LLC as the sole defendant.

The Ninja Foodi Power Blender & Processor from SharkNinja is a countertop appliance that uses a single motor base to operate both a high-speed blender and food-processing attachments. The system can be used for tasks such as blending, chopping, mixing dough and slicing or shredding ingredients, depending on the accessories installed.

While these small blenders have become a common household item, manufacturers have faced a series of lawsuits over dangerous defects. A series of SharkNinja blender lawsuits have been filed claiming the company’s devices can explode during use, sending plastic shards, metal blades and hot liquids toward users. Similar allegations have been made in lawsuits involving NutriBullet blender systems, which plaintiffs say do not adequately account for heat and pressure buildup during normal operation.

These reports reflect broader safety concerns tied to common kitchen appliances. Many of the same safety concerns have appeared in pressure cooker lawsuits against brands such as Ninja Foodi, Instant Pot and Crock Pot, in which plaintiffs allege that faulty lid-locking mechanisms allow the lids to open while the contents are still pressurized, causing hot food to erupt and leading to severe burn injuries.

According to his lawsuit, Jacobsen was using a Ninja Foodi Power Blender & Processor System on December 31, 2023, when the stacked blade assembly detached during normal operation. The complaint indicates the loose blades fell from the pitcher as he poured, causing what it describes as “serious and substantial” lacerations to his fingers.

The filing states that the blender’s design relies on a removable blade column that is not locked or secured to the drive gear, despite SharkNinja allegedly knowing for years that this configuration could allow the blades to fall out unexpectedly. The complaint points to a 2015 U.S. Consumer Product Safety Commission (CPSC) recall involving earlier Ninja BL660-series blenders, which reported at least 53 laceration injuries linked to the same issue of loose blades.

Jacobsen alleges that SharkNinja continued selling newer models with similar unsecured blade assemblies, including the CO351B model he purchased, even though safer alternative designs existed. The lawsuit claims the company failed to adequately test the product, failed to warn consumers of the risks, and continued marketing the system as safe for everyday kitchen use.

As a result of the incident, Jacobsen claims he suffered significant physical injuries, medical expenses, and long-term effects on his quality of life.

“The Ninja blenders have been designed and manufactured such that consumers cannot safely use them in the intended manner without risk of physical injury.”
