Massimo Motor Sports Recalls Percussion Massage Guns Due to Fire Hazard; Sold Exclusively at Costco

What was recalled

If you recently purchased a percussion massage gun from Costco, it is important to pause and check your device carefully. Massimo Motor Sports has issued a voluntary recall affecting every single model of their Percussion Massage Gun. This is not a limited batch or a specific color variant; the recall encompasses all units of this product line that were distributed through their exclusive retail partner. Specifically, these devices were sold exclusively at Costco stores and on Costco.com. If your massage gun came from any other retailer, it is likely outside the scope of this specific action, but if you bought it at Costco, you need to verify your device immediately.

The core of this recall centers on a specific hardware configuration. All affected units are identified by the model number EM003. You can confirm this by looking at the product information card located inside the original packaging. These massage guns were marketed with 20 distinct speed levels and came bundled with six interchangeable massage heads to target different muscle groups. They feature a built-in, rechargeable lithium-ion battery system, which is the component at the heart of the safety concern. The devices were available in four color options: black, silver, gold, and blue. Regardless of the exterior color you chose, if the internal model number is EM003, the unit is part of this recall.

The timeline for these sales is critical to understanding who might be affected. Massimo Motor Sports announced this recall on January 6, 2021. While the announcement date is in the past, these products may have been sold for several months prior to that date. Because the recall applies to "all models" of the EM003 line sold at Costco, there is no way to distinguish safe units from unsafe ones based on the manufacturing date alone without checking the model number directly. The scope is broad because the defect is inherent to the battery system design used across the entire product run, not a flaw that developed in only a few units.

We do not have the exact total number of units sold at this time in the official records provided by the Consumer Product Safety Commission (CPSC). However, the fact that three separate fire incidents have already been reported underscores that this is an active safety issue affecting real consumers. The lack of a specific unit count does not diminish the urgency; if you own a Massimo Percussion Massage Gun model EM003 purchased at Costco, you should treat every single one as potentially hazardous until proven otherwise by the remedy process.

It is also worth noting that these were consumer-grade devices intended for home use. They are not industrial equipment or professional medical devices, which means they may be sitting in a guest room, basement, or bedroom, often plugged in overnight or left charging unattended. This context makes verifying your possession of the item even more vital, as these devices are commonly given as gifts or kept in shared living spaces where multiple people might use them without realizing the specific model number.

The hazard, explained

When you pick up a percussion massage gun, you expect a powerful tool that delivers relief through rapid, rhythmic pulses. However, the specific danger here lies not in the mechanical motor or the striking attachment, but in the heart of its power source: the built-in rechargeable lithium-ion battery system. According to the Consumer Product Safety Commission (CPSC), this particular component has been found to have a flaw that allows it to overheat during use or charging. While lithium-ion batteries are standard in everything from smartphones to electric vehicles, they rely on complex internal chemistry to store energy. When these cells function correctly, they remain stable. But when there is a defect in the manufacturing process, a failure in the battery management system, or physical damage that compromises the internal separators, the battery can enter a state known as thermal runaway.

Thermal runaway is a self-perpetuating cycle of rising heat. As the battery overheats, the chemical reactions inside accelerate, generating even more heat, which further destabilizes the cell. This process can happen relatively quickly and without obvious warning signs to the user until it is too late. The intense heat generated by an overheating lithium-ion cell can melt surrounding plastic components, ignite nearby materials, and in severe cases, cause the battery casing to rupture or explode. This is not just a matter of the device breaking; it is a genuine fire hazard that can spread rapidly if the device is left unattended or placed on combustible surfaces like bedding, furniture, or carpets.

The seriousness of this specific defect is underscored by the incident data reported by Massimo Motor Sports. They have received three confirmed reports of fires involving these recalled massage guns. These were not minor smoke incidents; the resulting property damage totaled over $15,000. This figure highlights how quickly a small electronic failure can escalate into significant physical destruction. Fortunately, no injuries have been reported in these cases, but the potential for serious harm remains high. Fires ignited by lithium-ion batteries can produce toxic fumes and spread to other parts of a home or office before a user even realizes what is happening. The risk is compounded by the fact that massage guns are often used on soft surfaces, such as sofas or beds, where heat cannot dissipate easily and flammable materials are close at hand.

It is important to understand that this hazard is intrinsic to the battery system itself, not how you use the device. Even if you use the massage gun exactly as intended, for the recommended duration, and with proper ventilation, the defective cells can still overheat. This unpredictability is why the remedy is so strict: immediate cessation of use. You cannot simply "be careful" to mitigate this risk because the failure mode is internal and chemical, not behavioral. The only way to eliminate the danger is to remove the source of the heat—by stopping use entirely and obtaining a refund for the defective unit.

Who is most at risk

While any user of the Massimo Percussion Massage Gun faces a genuine safety threat due to the potential for the lithium-ion battery system to overheat and ignite, the nature of this hazard creates specific vulnerabilities for certain groups of people. The primary group at risk consists of individuals who have purchased these devices exclusively from Costco. Because these units were sold only through that specific retail channel, your likelihood of owning one depends entirely on whether you made a purchase there prior to the recall date of January 6, 2021. However, beyond mere ownership, the physical and environmental context in which the device is used significantly influences the level of risk.

The most immediate danger arises for anyone using the massage gun in close proximity to flammable materials. These devices are often used on beds, couches, carpets, or soft furniture where heat can become trapped. If the internal battery overheats while the device is resting on a mattress or a cushion, the surrounding fabric can easily catch fire. This puts homeowners and renters who use these tools for relaxation in living spaces at higher risk than those who might use them in more open, industrial-style environments. The recall notes that there have already been three reported fires resulting in over $15,000 in property damage, proving that this is not just a theoretical risk but an active one affecting real homes.

Certain demographics may be particularly vulnerable to the consequences of such an incident. For instance, elderly individuals or those with limited mobility often rely on massage guns for pain relief and daily comfort. They may use the device while resting in bed or sitting for extended periods. If a fire were to start while they are sedentary or potentially asleep, their ability to react quickly could be compromised. Similarly, households with young children present a unique risk profile. Children are naturally curious and may not recognize the warning signs of an overheating battery, such as unusual warmth or strange odors. They might also accidentally trigger the device, causing it to overheat while unattended in a play area or bedroom, leading to rapid fire spread in spaces filled with toys and bedding.

Furthermore, anyone living in older housing structures with outdated electrical wiring or fire suppression systems may face greater danger. A battery fire can escalate quickly, and without immediate detection by smoke alarms that are functioning correctly, the risk of significant property loss increases. It is also important to note that while no injuries have been reported so far, the potential for injury remains high if the device ignites in a confined space or near a person’s body. The lithium-ion chemistry involved can produce intense heat and toxic fumes, posing respiratory risks to anyone nearby. Therefore, everyone who owns this product, regardless of age or physical ability, is technically at risk, but those using it in sleeping areas, near combustible materials, or while unsupervised face the most severe potential outcomes.

How to tell if you have the recalled item

Before you take any action or contact the manufacturer, it is essential to confirm with absolute certainty that your specific percussion massage gun is part of this recall. Because Massimo Motor Sports has recalled all models of their Percussion Massage Gun under this specific safety notice, the identification process relies on a combination of brand naming, model numbers, and packaging details rather than just visual appearance alone. This distinction is critical because while the hazard is tied to the battery system within these units, verifying the exact product ensures you are not confusing it with other non-recalled massage devices you might own.

The primary identifier for this recall is the brand name Massimo. You should first look at the device itself and its original packaging for the Massimo logo. If your unit is from a different manufacturer, it is not subject to this specific CPSC action. Assuming you have a Massimo product, the next step is to locate the model number. According to the recall facts, all affected units fall under model number EM003. This model number is typically printed on the Product Information Card included inside the package. If you have discarded the box or the card, check the bottom of the massage gun handle or the base of the device for a label containing the serial number and model information.

While the recall covers all units regardless of color, knowing the available finishes can help you narrow down your search if you are unsure which device it is. These massage guns were sold in black, silver, gold, and blue. The devices feature 20 speed levels and come with six interchangeable massage heads. They also include a built-in rechargeable lithium-ion battery. If you have a Massimo percussion gun that matches these physical characteristics but cannot find the EM003 model number, it is highly likely to be part of this batch, but verifying via the packaging card remains the most reliable method.

Another crucial factor in identification is where and when you purchased the item. These recalled massage guns were sold exclusively at Costco. If you bought your Massimo percussion gun from a different retailer, such as Amazon, Walmart, or a specialty fitness store, it may be a different product line not covered by this specific recall. However, if you did purchase it at Costco, check your receipt or credit card statement for the date of purchase relative to the recall date of January 6, 2021. Even if you bought it years ago, the safety defect remains relevant until you resolve it.

To summarize, look for these three key confirmations: the Massimo brand, the model number EM003 (found on the info card or device label), and a purchase history linked to Costco. If all three align, you have one of the recalled units and should proceed with the remedy steps outlined in this article.

What to do — step by step

Your refund, repair, or replacement options

If you have determined that you possess one of the recalled Massimo Percussion Massage Guns, the good news is that the remedy for this specific safety issue is straightforward and consumer-friendly. Unlike some complex recalls that require sending items back to a central warehouse for intricate repairs or waiting weeks for replacement units to be manufactured and shipped, the recall notice from CPSC indicates that Massimo Motor Sports is offering a full refund. This means you do not need to return the defective product to receive your money back. Instead, the process is designed to be as low-friction as possible, recognizing that keeping a potentially hazardous lithium-ion battery in your home is not worth the wait or the hassle of shipping it.

To initiate this refund, you will need to contact Massimo Motor Sports directly. The company has established specific channels for consumers to reach out regarding this recall. You can call their toll-free number at 877-881-6376. When you call, please be aware that their customer service team is available from 8:30 a.m. to 5:30 p.m. Central Time, Monday through Friday. If you prefer to handle this online, you can visit their website at www.massimotor.com. Once on the site, look for the "Product Recall" link located at the top of the page. This section of the website likely contains additional details or a form to help facilitate your claim.

While the recall facts provided do not specify exactly what documentation you might need to provide (such as a receipt, proof of purchase, or photos of the model number on the product information card), it is generally wise to have your purchase records ready. Since these units were sold exclusively at Costco, having your membership card or order confirmation email may help speed up the process. If you encounter any difficulties reaching Massimo Motor Sports via phone or their website, CPSC often provides alternative contact methods or can direct you to further assistance, though the primary point of contact remains with the manufacturer for this specific remedy.

The decision to offer a full refund rather than a repair is significant. Because the hazard involves the lithium-ion battery system overheating, attempting to fix the internal components would be dangerous and impractical for an average consumer. A replacement unit would also carry the same risk unless Massimo has released a completely new design with updated safety features, which is not stated in the current recall information. Therefore, accepting the refund is the safest path forward. It allows you to remove the fire hazard from your home immediately while getting your money back. Once the refund process is complete, please dispose of the recalled massage gun responsibly according to local electronic waste regulations, ensuring it does not end up in a landfill where it could still pose a risk.

What can happen if you ignore it

When a recall notice lands in your inbox or appears on a government safety website, it is natural to feel overwhelmed. You might think, "My battery has held up fine for months," or "I only use this for ten minutes at a time." It is completely understandable to want to justify keeping the device, especially if you have invested time into learning its settings or simply do not want the hassle of packing it back up and mailing it away. However, with the Massimo Percussion Massage Guns recalled by the Consumer Product Safety Commission (CPSC), ignoring the warning carries consequences that extend far beyond a simple inconvenience. The core issue lies in the lithium-ion battery system, which has been identified as capable of overheating. This is not a minor glitch; it is a fundamental failure of the power source that can escalate rapidly.

The most immediate and severe risk is fire. Lithium-ion batteries rely on precise chemical stability to function safely. When the internal components degrade or malfunction, as they appear to be doing in these specific units, the battery can enter a state known as thermal runaway. In this scenario, the heat generated by the battery itself causes a chain reaction that increases temperature further, leading to swelling, venting of flammable gases, and ultimately, ignition. Massimo Motor Sports has already confirmed three separate incidents where these massage guns caught fire. While no injuries have been reported in these specific cases, the property damage exceeded $15,000. This figure represents significant destruction to homes, furniture, or other belongings. A fire does not always start with a massive explosion; often, it begins as a small smolder that spreads quickly through nearby materials like curtains, carpets, or bedding.

Beyond the risk of property loss, there is the very real danger of personal injury. Although current reports do not list injuries, the proximity of these devices to the human body makes them particularly hazardous. Massage guns are typically used while sitting on a couch, lying on a bed, or standing near walls and flooring. If the device ignites while in your hands or resting against your skin, the resulting burns could be severe. Even if you are not holding it, a battery fire can release toxic fumes that are dangerous to inhale, posing respiratory risks to you and your family. The unpredictability of lithium-ion failures means you cannot rely on warning signs like smoke before ignition occurs; the transition from overheating to fire can happen in seconds.

Ignoring the recall also leaves you without recourse. Once a device is recalled due to a fire hazard, it is effectively deemed unsafe by federal standards. If you continue to use it and an incident occurs, your ability to claim insurance or seek compensation may be complicated by the fact that you knowingly continued using a product identified as dangerous by the manufacturer and the CPSC. The remedy offered—a full refund—protects you from financial loss on the device itself while removing the hazard from your home. Choosing to keep the massage gun is essentially gambling with your safety for the sake of temporary convenience, a risk that simply does not pay off when the alternative is a guaranteed refund and peace of mind.

Staying safe: broader tips

Living with high-power consumer electronics requires a mindset of proactive respect for their capabilities. While the specific recall involving Massimo Motor Sports massage guns highlights a rare but serious defect in lithium-ion battery systems, the broader lesson applies to nearly every modern device that stores energy or generates heat. The most critical step in maintaining long-term safety is establishing a habit of regular product registration. Many consumers view this as mere administrative paperwork, but it is actually your primary lifeline to manufacturers during emergency situations. By ensuring your email address and model numbers are current in their database, you ensure that if a latent defect is discovered months or even years after purchase, you are among the first to know. This simple administrative act can prevent thousands of households from using potentially dangerous products unknowingly.

Equally important is understanding how to care for lithium-ion batteries, which power everything from massage guns to power tools and electric vehicles. These batteries degrade over time and are sensitive to physical stress. To extend their lifespan and reduce the risk of thermal runaway—a condition where a battery overheats uncontrollably—avoid leaving devices plugged in for extended periods once they are fully charged. Never store these items in extreme temperatures, such as inside a hot car during summer or a freezing garage in winter, as temperature extremes can damage the internal chemical structure of the cell. Additionally, inspect your charging cables and ports regularly for fraying or debris. A compromised connection can create resistance, leading to excessive heat generation that the device’s safety sensors might not be fast enough to detect.

Finally, cultivate a routine of checking official recall databases, even when you do not own the specific item mentioned in recent news. The U.S. Consumer Product Safety Commission (CPSC) and other regulatory bodies publish lists of recalled items daily. By subscribing to their email alerts or visiting their site weekly, you protect your home from hazards that have nothing to do with massage guns and everything to do with faulty cribs, defective stoves, or dangerous children’s toys. Safety is not just about reacting to a crisis; it is about building a household environment where risks are identified and mitigated before they ever become incidents. Treat your electronics with the same care you would treat a gas appliance: respect their power, maintain them diligently, and stay informed.
