NutriBullet Blender Explosion Lawsuit Alleges Scalding Smoothie Caused Severe Burns

Lawsuit claims blender sprayed scalding hot liquid onto a woman’s face and body as she attempted to remove the blade assembly.

A Massachusetts woman has filed a product liability lawsuit alleging NutriBullet failed to incorporate adequate pressure relief mechanisms and safety warnings into their popular personal blenders.

The complaint (PDF) was brought by Lucelina Barros in Massachusetts Superior Court on October 22, 2026, naming NutriBullet LLC and Capital Brands Distribution LLC as defendants.

Barros claims the explosion caused serious injuries that required hospitalization and left her with lasting physical complications.

Blender Burn Injury Risks

NutriBullet blenders are personal countertop appliances that use a sealed blending cup instead of a traditional pitcher and lid. The cup connects to a blade assembly powered by a motorized base, which rapidly spins stainless steel blades to break down and mix ingredients.

Although NutriBullet blenders are not designed to heat or cook food, the friction generated during blending can raise the temperature of ingredients inside the sealed cup. Many models recommend limiting blending to one minute at a time to prevent excessive heat and pressure from building up. If the pressure becomes too high, removing the blade assembly may cause hot contents to erupt from the container, posing a risk of serious burns.

Several NutriBullet explosion lawsuits allege that design defects allow dangerous levels of pressure to develop during use, causing blending cups to rupture or separate unexpectedly. These failures can send scalding liquids, metal components and plastic debris toward consumers, resulting in severe injuries.

Similar allegations have been raised in Ninja Nutri blender lawsuits, which claim the appliances lack adequate safeguards to prevent dangerous pressure buildup during normal operation.

The claims also resemble those raised in pressure cooker lawsuits involving Ninja Foodi, Instant Pot and Crock-Pot appliances. Those cases allege defective lid-locking mechanisms and other safety failures allow consumers to open pressure cookers before the internal pressure has been released, causing hot food, steam and liquids to erupt and inflict severe burns.

NutriBullet Injury Allegations

According to the complaint, Barros was preparing a smoothie in her NutriBullet NB-201B 900-watt blender on December 31, 2024. After blending the ingredients for approximately one minute, she stopped the appliance and removed the cup and blade assembly from the motorized base.

When Barros attempted to unscrew the blade assembly from the cup, the container allegedly separated explosively, spraying scalding hot liquid onto her face and body. She claims the explosion resulted from excessive heat and pressure generated by friction from the blender’s high-speed blades.

Barros says she suffered burns to her face, eyelids, arm and wrist and was transported by ambulance to a hospital for emergency treatment before being referred to a burn unit. She continues to experience scarring, disfigurement and residual pain.

The lawsuit alleges NutriBullet markets its appliances as durable, high-powered blenders suitable for everyday use, despite design defects that allow dangerous heat and pressure to accumulate inside the sealed cups.

Barros maintains the blender lacks adequate pressure relief mechanisms and indicators to warn users of excessive heat or pressure before opening the container. The complaint identifies several safer alternative designs, including pressure relief valves, venting mechanisms and automatic shutoffs that limit blending time to one minute.

The filing also claims existing warnings are printed in small lettering on the back of the blender’s base, where they are difficult to see during normal use. Barros alleges the warnings fail to adequately explain that heat and pressure can build up inside the cup, causing it to separate explosively and eject scalding contents.

NutriBullet and Capital Brands allegedly knew or should have known about the risk of overheating, pressure buildup and exploding blender cups based on consumer complaints and similar incidents dating back to at least 2011. The filing specifically references a 2014 report involving a NutriBullet cup that allegedly exploded after blending, causing burns.

Despite that knowledge, Barros claims the companies continued selling the appliances without adopting safer alternative designs, providing adequate warnings or recalling the allegedly defective products.

“NutriBullet negligently failed to recall the subject blender after learning the product was defective, prone to failure, and prone to cause injury to users, which created an increased risk of injury to the Plaintiff and the consumer public.”

Barros raises claims of negligence, breach of the implied warranty of merchantability and violations of Massachusetts consumer protection law. She seeks compensation for medical expenses, pain and suffering, permanent scarring and disfigurement, as well as up to triple damages and attorney’s fees under Massachusetts law.
