What was recalled
The Consumer Product Safety Commission (CPSC) has issued a recall notice concerning specific portable generators manufactured by Kohler Power Systems. This safety action, announced on August 9, 2016, targets a distinct set of units that were produced prior to June 2016. The affected products are identifiable by their physical design characteristics: they feature black frame assemblies and blue fuel tanks. Kohler has identified five specific model numbers within this recall scope: the PRO3.7, PRO3.7E, PRO5.2, PRO5.2E, and GEN5.0. Consumers should note that the GEN5.0 model is unique in that it includes a specific specification number, PA-GEN50-3003, which must be verified to confirm inclusion in this recall.
To determine if your generator is part of this batch, you must look closely at the manufacturing details rather than just the model name. The recall applies only to generators with a serial number of 4528733735 or lower, and which bear a manufacture date prior to June 2016. This information is located on a silver label affixed to the lower black frame assembly of each generator. It is crucial to check both the serial number and the month/year code, as generators with later production dates are not included in this safety action. The models PRO3.7, PRO5.2, and GEN5.0 were sold with manual recoil start mechanisms, while the PRO3.7E and PRO5.2E variants were equipped with both manual recoil and electric start options.
The specific units affected by this recall were sold at various retail locations across the United States. While the exact list of retailers is not detailed in the summary provided, these generators were distributed widely during the production window leading up to June 2016. If you purchased a Kohler portable generator with the described black frame and blue tank configuration before mid-2016, it is essential to verify your serial number against the cutoff date. The recall does not apply to all Kohler generators, only those meeting the specific criteria of model type, serial number range, and manufacturing date. This precise identification process ensures that consumers can accurately determine whether their equipment requires immediate attention.
Kohler Power Systems has been notified of this defect, and they are actively working to address the issue through a free repair program. The company urges owners to contact them directly to arrange for service at an authorized dealer. By providing clear identification steps and direct contact information, Kohler aims to help owners quickly resolve the safety concern without unnecessary delay. If you are unsure whether your generator falls under this recall, checking the silver label on the frame is the most reliable first step. This careful verification process protects consumers from potential hazards while avoiding inconvenience for those with newer or different models.
The hazard, explained
At the heart of this recall is a seemingly simple but dangerous wiring error inside Kohler portable generators. When you plug an electrical device into one of these units, you expect the electricity to flow safely from the generator’s internal engine and alternator, through its designated outlets, and into your appliance. This process relies on precise insulation and correct physical connections to keep high-voltage current contained within the wires where it belongs. In the affected models, however, that containment has been compromised due to a manufacturing defect in the wiring assembly. Because of this error, live electrical wires may come into unintended contact with the generator’s metal frame or other conductive parts that are not supposed to carry current.
Under normal circumstances, if a wire inside your generator were to fray or break, it might cause the unit to malfunction or stop working entirely. But in this specific case, the wiring fault creates a path for electricity to "leak" onto the exterior of the machine. This is known as an energized chassis. When the metal frame becomes electrified, anyone who touches the generator while also touching a grounded surface—such as wet grass, a concrete patio, or even just standing on damp earth—completes the electrical circuit. Your body inadvertently becomes the bridge between the high-voltage source and the ground, allowing electricity to surge through you.
The physical result of this shock can range from a painful jolt to severe injury or death, depending on the voltage level and the duration of contact. Portable generators are often used in outdoor settings for camping, tailgating, or emergency home backup during power outages. These environments frequently involve moisture, which drastically increases the risk of electrical conduction. Water is an excellent conductor of electricity, so if rain falls on the generator or if you are working near puddles, the danger multiplies. Even without water, bare hands touching a live metal frame can deliver a severe shock that causes muscle spasms, making it difficult for a person to let go of the energized object.
It is important to understand that this hazard exists regardless of whether you are actively using an appliance or simply standing near the unit. The wiring error means the generator itself has become a potential source of electrocution, not just a provider of power. While no incidents have been reported to date, the potential for harm is significant because the defect is hidden within the machine’s internal components. You cannot see the bad wire, and you cannot feel the danger until it is too late. This is why immediate cessation of use is critical; waiting for a visible sign of trouble, such as sparks or burning smells, may leave no time to react before an accident occurs.
Who is most at risk
When we talk about electrical hazards in portable generators, it is helpful to first understand who is likely to be holding the plug when things go wrong. The Kohler models recalled here—specifically the PRO3.7, PRO3.7E, PRO5.2, PRO5.2E, and GEN5.0—are typically used by homeowners, small contractors, or individuals living in areas prone to power outages. These are not industrial-grade machines left in locked warehouses; they are often stored in garages, basements, or even on porches, accessible to family members. The primary group at risk is anyone who plugs standard household appliances, power tools, or extension cords into these units. Because the defect involves a wiring error that creates a shock hazard whenever a device is plugged in, the danger is not passive. You are only at risk when you actively connect something to the generator. This means the person operating the equipment, whether they are starting up the unit for the first time or switching loads during a storm, is the first line of exposure.
However, vulnerability extends beyond just the operator. In many households, portable generators are placed in shared spaces like driveways, patios, or near windows to vent exhaust safely while powering indoor essentials. Children and pets often explore these areas, unaware that a piece of machinery with exposed metal frames and power outlets is potentially live. If a child touches the black frame assembly or an outlet while a device is plugged in, they could receive a shock. The risk is particularly acute for young children because their skin is thinner than adults’, making them more susceptible to electrical current, and they may not recognize the danger of touching metal parts near power sources. Furthermore, elderly individuals or those with mobility issues who rely on generators for medical equipment (like oxygen concentrators or refrigerators for medication) are at heightened risk. A shock incident could cause a fall or panic, leading to secondary injuries, while also cutting off critical power at a dangerous moment.
We must also consider the context of use. These units were manufactured prior to June 2016 and have serial numbers 4528733735 or lower. Owners who still possess these older models may be less familiar with modern safety standards, having used them for years without incident. This familiarity can breed complacency. The wiring error is hidden inside the unit; you cannot see it, smell it, or hear it until a shock occurs. Therefore, the most vulnerable users are those who assume their generator is safe because it has worked fine in the past. The hazard does not discriminate by age, but it disproportionately affects those who are least aware of the electrical potential within the machine’s frame and outlets. If you have any family members who are not tech-savvy or who might handle the equipment without reading the manual, they are at the highest risk because they may not know to stop using the device immediately upon learning of this recall.
How to tell if you have the recalled item
If you own a Kohler portable generator, determining whether your specific unit is part of this recall requires careful attention to detail. Because the issue stems from a specific manufacturing window and wiring configuration, not every Kohler generator is affected. To be certain, you must verify three distinct pieces of information: the model number, the serial number, and the date code. This process is straightforward but demands that you locate the official identification label on your machine.
First, look at the physical characteristics of your generator to narrow down the potential candidates. The recalled units are visually distinct in their color scheme. You should be looking for a generator with a black frame assembly and blue fuel tanks. If your unit has different coloring, it is likely not part of this specific recall. Next, examine the starting mechanism based on the model type. The PRO3.7, PRO5.2, and GEN5.0 models feature manual recoil starts, meaning you pull a cord to start the engine. The electric-start variants, specifically the PRO3.7E and PRO5.2E, come equipped with both manual recoil and electric start capabilities. However, visual inspection alone is not enough; you must confirm the exact model number.
The most critical step is locating the silver identification label. This label is affixed to the lower black frame assembly of each generator. It contains the vital data points needed for verification. You need to check four specific items on this sticker:
- Model Number: Ensure your unit is one of the following: PRO3.7, PRO3.7E, PRO5.2, PRO5.2E, or GEN5.0.
- Spec Number: For the GEN5.0 model, the spec number must be PA-GEN50-3003.
- Serial Number: This is a unique identifier for your unit. The recall only applies to generators with a serial number of 4528733735 or lower.
- Date Code: Look for the manufacturing date, formatted as the month and year (MM YYYY). The recalled units were manufactured prior to June 2016.
It is important to understand why these specific numbers matter. The wiring error that creates the shock hazard was corrected in later production runs. Therefore, any unit made in or after June 2016 is safe from this particular defect. Similarly, if your serial number is higher than 4528733735, it falls outside the affected batch. If you cannot find the silver label, or if the information does not match these criteria exactly, your generator is likely not part of this recall. However, if all the details align with the description above, you should stop using the unit immediately and proceed to the remedy steps outlined in the next section.
What to do — step by step
If you own one of the Kohler portable generators affected by this recall, your immediate priority is safety. The potential for an electrical shock is serious, so please follow these steps carefully to protect yourself and your household. First, stop using the generator immediately. Do not plug any devices into it, and do not attempt to turn it on again. This is critical because the hazard stems from a specific wiring error within the unit that can energize parts of the generator meant to be grounded. Continuing to use the device puts you at risk of severe injury. Treat the generator as if it were live until it has been inspected and repaired by an authorized professional. Next, locate your generator’s identification information. You will need this to verify whether your specific unit is included in the recall and to help Kohler process your repair. Look for a silver label attached to the lower black frame assembly of the generator. On this label, you will find four key pieces of information: the model number, the serial number, the specification number, and the manufacturing date code. To confirm if your generator is part of this recall, check these details against the criteria below. Your unit must meet ALL of the following conditions to be included in this specific safety notice:- Model Numbers: The model must be one of the following: PRO3.7, PRO3.7E, PRO5.2, PRO5.2E, or GEN5.0.
- Specification Number: For the GEN5.0 model, the spec number must be PA-GEN50-3003.
- Serial Number: The serial number must be 4528733735 or lower.
- Manufacture Date: The date code must indicate a manufacture date prior to June 2016 (06 2016).

What can happen if you ignore it
It is completely understandable why you might hesitate to stop using your Kohler portable generator. Perhaps the power outage that prompted its purchase has ended, but you still need it for a weekend camping trip or as a backup for occasional outages. Maybe the unit is sitting in your garage, and moving it feels like too much effort. Or perhaps you are simply busy, and the prospect of scheduling a repair appointment seems like an unnecessary hassle on top of everything else. These feelings are normal, but they mask a serious underlying risk that should not be ignored. The core issue with these specific Kohler models—PRO3.7, PRO3.7E, PRO5.2, PRO5.2E, and GEN5.0—is not a mechanical failure that will break the engine; it is a fundamental electrical safety flaw. The wiring error present in units manufactured prior to June 2016 creates a direct path for electricity to flow where it should not. This means that the very act of plugging in a lamp, a phone charger, or a medical device transforms your generator from a helpful tool into a potential danger.
The primary consequence of continuing to use this recalled generator is the risk of severe electrical shock. When you plug an electrical device into a generator with this wiring defect, the protective grounding mechanisms may fail. Instead of safely directing stray current away from you and your equipment, the error can cause the metal casing or internal components to become energized. If you touch the generator while it is running, or if you are holding a plugged-in device that has developed a fault, you could receive a dangerous shock. While the Consumer Product Safety Commission reports no incidents of injury or death associated with this specific recall as of its announcement date, the absence of reported cases does not mean the risk is zero. It simply means that, so far, users have been fortunate enough to avoid harm. Relying on luck when dealing with high-voltage electricity is never a safe strategy.
Beyond the immediate threat to human health, ignoring this recall can lead to secondary dangers. Electrical shorts caused by wiring errors can generate intense heat, potentially melting insulation or ignifying nearby combustible materials like gasoline vapors, dust, or stored items in your garage. This creates a fire hazard that extends beyond the generator itself. Furthermore, using defective electrical equipment can damage the sensitive electronics of the devices you are trying to power. Modern appliances, from refrigerators to medical monitors, contain complex circuitry that is vulnerable to voltage spikes and improper grounding. By continuing to use this generator, you risk destroying the very items you rely on.
The most practical consequence of inaction, however, is the loss of peace of mind. A generator should be a source of security, not anxiety. Every time you plug something in, you are left wondering if today will be the day the wiring fails. By taking the few minutes to contact Kohler and schedule your free repair, you eliminate this uncertainty. The remedy is straightforward and cost-free, but it requires action on your part. Do not wait for a shock or a spark to convince you that the risk was real. Addressing the issue now ensures that your generator remains a reliable asset rather than a hidden liability in your home.
