SaferProducts.gov consumer incident report 20130218-98BBB-2147458700. Severity: Injury, Emergency Department Treatment Received. Matched catalog product: Ninja Ninja Auto IQ 1000W Blender. Source model text: ks1100. Incident: I was using the blender for the first time. I put it together as shown in the quick start guide. After blending my smoothie I tried to pour some of it through the small flip top lid but it was too thick so I had to remove it. the blade tower seemed to snap into place when I placed it in the unit and I thought it secured. As I poured some of the smoothie into a cup to check the consistency the blade tower came out slicing my thumb. When I contacted the company I was told that I should reach into the blender and whatever is in the blender to remove the blade tower before pouring anything. This makes no sense since the blades are covered by in this case a thick, viscous and opaque material ie... fruit smoothie. I could not see the location of the blades in the unit nor would I stick my hands in and grab them if I could. This product is inherently unsafe and the company should know that.

Government / agencyIndexed Oct 28, 2026Source-linkedVerify source — SaferProducts.gov incident

SaferProducts.gov consumer incident report 20161107-A17A7-2147411031. Severity: Incident, No Injury. Matched catalog product: Ninja Ninja Auto IQ 1000W Blender. Source model text: Model BL682. Incident: I have a Nutri Ninja� Blender System with Auto-IQ� Model BL682 which I purchased from Bed Bath and Beyond. I previously had their Model BL740 which has the same problem. The blender blades has a hard plastic casing and a rubber o-ring to give a proper seal when using the blender for the NutriNinja cups. The debris from blended food becomes lodged between the rubber ring and the hard plastic casing of the blade housing resulting in build up of decaying food, mold, and a putrid odor. I contacted the manufacturer asking if there is a way to easily remove the rubber ring for proper cleaning and they informed me that the rubber ring should not be removed. This leaves the consumer with the problem that food debris will become lodged there posing a health hazard. I have looked online and found many posts from people with similar problems and they ultimately removed the rubber ring using a knife or other tool and found a large amount of rotting food matter. The instructions that come with the product for cleaning (fill blender with soapy water and run it on the blender) only cleans the blade and does nothing for the debris that is stuck between the rubber ring and the hard casing.

Incident: The charging port and the USB-C charging cord (original cord provided) of my Ninja Blast Blender model BC151BK burned/melted while charging my blender. I had used the provided USB-C, plugged into a block, it can take 2 hours to charge so I plugged it in as I left for work. When I returned there was black charred pieces on the counter, flame burns at the USB-C port and the charging cord itself was melted down approximately 1/4 inch. Thankfully it stopped there, and it was on a solid counter and the various mail, recipe cards were about 5 inches away. There is no doubt my house would have burned down.

SaferProducts.gov consumer incident report 20240620-CC6D2-2147338503. Severity: No Incident, No Injury. Matched catalog product: Ninja Ninja Auto IQ 1000W Blender. Source model text: SS101. Incident: The blender does not include any directions whatsoever on cleaning the rubber gasket around the blade. I have been following all the directions in the manual and couldnt understand why an awful smell was coming from the blade. After searching online I found that people are having to use crochet hooks to remove the gasket to clean them. Mine is covered in mold and has to be thrown away. Ninjas solution is for consumers to purchase a whole new blade that will include a new gasket at a total cost of almost half the blender as its not covered under warranty even though this is a defect in design. Directions need to be included on how this should be cleaned after every use and a tool should be provided in the box to do so. This is a serious health hazard. Third party companies are having to step in to help consumers solve this problem in order to keep their unit working in a healthy manner. If this unit was used in a commercial setting without being cleaned properly I can only imagine the problems it would cause.

SaferProducts.gov consumer incident report 20260917-A318B-2147309742. Severity: Incident, No Injury. Matched catalog product: Ninja Ninja Auto IQ 1000W Blender. Source model text: BN401. Incident: I reported that I purchased the Ninja Auto IQ Nutri Blender Pro on August 19th from Kohl's (receipt attached). I used the blender once about ten days later and then not again after. At that time, when I made two smoothies, I noticed a burning smell but I thought that it was because the blender was new. I read the manual before I used the blender and followed instructions. I placed the Ninja on my counter where it was not near any other small appliances or anything electrical. I also do not keep any kitchen appliances plugged in when it is not in use. On September 10th, the Ninja combusted by itself without any source of power or anything flammable near it. It was not powered on, and no one was even in the kitchen when the Ninja started to combust. It burst into flames at which time my daughter put on oven mitts, picked up the Ninja, tossed it on a metal grill on top of our stove, and then threw it outside. That combustion ruined part of our counter, singed the immediate surrounding area, and blackened our kitchen ceiling. Thankfully we were home mid-afternoon! I can't even imagine what this combustion could have caused had we not been home. It could have very well burned our house down. Needless to say, I needed to report this and request you to investigate this product. The burnt remains are still stuck on the metal grill, melted on it. You can certainly take it, if needed.

SaferProducts.gov consumer incident report 20150513-F4C23-2147432978. Severity: Injury, Emergency Department Treatment Received. Matched catalog product: Ninja Ninja Auto IQ 1000W Blender. Incident: I seriously cut myself twice within 15 minutes while using this blender for the first time. I would not recommend this blender for anyone. In my opinion it is defectively designed. The Ninja uses a long attachment with concentric circular blades much unlike the normal blade design typically used in blenders. The Ninja's "razor blade Christmas tree" design provides no discernible benefit over the normal blade design yet increases the risk of injury exponentially. I seriously cut the index finger on my right hand while inserting the blade attachment into the pitcher. Minutes later, the attachment fell out of the pitcher into my left hand while I was pouring the contents of the pitcher onto a plate (the poorly mixed, half-blended contents, I might add). It caused a deep gash in my palm requiring four stitches to close. The attachment fell out of the pitcher because it is designed to sit loose on the base of the blender with no secure connection whatsoever. Not surprisingly, a quick review of Safer Products complaints shows others have been injured in the same manner and even more seriously. I was lucky to escape with only four stitches. I immediately returned the blender to the place of purchase for a full refund. Avoid at all costs. The Ninja blender is needlessly dangerous, almost as if the manufacturer set out to create a booby trap. Mission accomplished.

SaferProducts.gov consumer incident report 20181024-D96D7-2147384837. Severity: Injury, Emergency Department Treatment Received. Product: Ninja Ninja Auto IQ 1000W Blender. Incident: ***********DO NOT BUY A SHARK NINJA BLENDER***************IT WILL BLOW UP ON YOU!!!!!!!!!!!!!!!!! At exactly 5:15 P.M. on January 25th 2018, My Ninja Blender Auto IQ exploded during removal off the lid after blending and I suffered deep second degree burns on my wrists, hands, face, and neck. The food that I put in the blender was room temperature and the blender heated up the food to the point that I was badly burned. Luckily I am cautious with protecting my head/face in emergency situations or my face would be completely scarred. I originally bought this blender to accommodate my daughter who is fed through G-Tube. I purchased the blender a year prior to the incident and used the blender 2-4 a day EVERY SINGLE DAY. The first time I used the blender I blended some dinner left overs (that was refrigerated over night) and my daughters prescription formula. When I went to take the lid off the pressure from blending it popped the lid off with a hard force and there was steam coming from the contents inside. I checked to feel the temperature and was surprised at how warm it was. I checked online to see if I could find any information on why it was making the food warm and with no luck, I just assumed that because the blenders blades rotated so quickly that it heated the content. As time went on I noticed that it kept heating food a little warmer after every use. I never imagined that it would have heated the food and exploded out of the container like it did, burning me in the process. My attorney contacted Ninja and explained the situation and the product malfunction. Ninja in
