Numerous injury reports, recall notices, and multiple lawsuits have raised concerns about the safety of certain Ninja blender models.
Unlike traditional blender designs that use fixed blades attached to the pitcher, many Ninja professional blenders use a removable stacked blade assembly that remains loose inside the container when the lid is removed.
Critics argue that this design can expose users to sharp blades during routine tasks such as pouring, emptying, cleaning, or handling the pitcher after blending.
The most significant safety action occurred when the U.S. Consumer Product Safety Commission (CPSC) announced a recall of more than one million Ninja BL660-series blenders.
According to the recall notice, the blender poses a laceration hazard if consumers pour or invert the pitcher while the loose stacked blade assembly remains inside.
The recall followed dozens of reported injuries involving cuts and lacerations caused by contact with the blade assembly.
Lawsuits filed against SharkNinja allege that certain blender models contain dangerous defects that can expose users to foreseeable injury risks during normal use.
Some injured consumers reportedly suffered deep hand and finger lacerations requiring stitches, emergency treatment, and, in severe cases, surgery to repair damaged tendons, nerves, or other structures.
When injuries involve significant tissue damage, victims may undergo surgical repair and lengthy rehabilitation before regaining function.
Plaintiffs contend that safer alternative designs, stronger blade retention systems, or additional warnings could have reduced the risk of serious harm to consumers.
How the Ninja Blade Assembly Is Alleged to Cause Injuries
Many Ninja blender lawsuits focus on the design of the removable stacked blade assembly rather than the blender’s ability to blend food.
Unlike conventional blenders that secure the blades to the bottom of the pitcher, certain Ninja models use a separate blade column that can be removed independently from the container.
Plaintiffs allege that this design increases the risk of accidental contact with sharp blades during everyday activities, particularly when users pour blended contents, wash the pitcher, or reach inside the container.
Several lawsuits claim that consumers were injured when the blade assembly unexpectedly shifted, detached, or remained hidden inside the pitcher after the lid was removed.
Because the blades extend vertically through much of the container, users may encounter multiple cutting surfaces at once, increasing the likelihood of severe lacerations.
Some reported injuries required immediate medical attention and involved nerve damage, tendon injuries, permanent scarring, or loss of hand function.
While litigation primarily focuses on removable blade assemblies, consumers have also raised safety concerns involving other SharkNinja products, including certain Ninja Foodi blender models and accessories such as Nutri Ninja cups.
The specific allegations vary by product and incident, but many claims share a common theme: consumers contend that dangerous defects exposed them to injury risks that were not adequately addressed through product design, warnings, or safety instructions.
Product liability cases involving Ninja blenders ultimately examine whether the product performed as an ordinary consumer would expect and whether alternative designs could have reduced the risk of injury without impairing the blender’s intended function.
