TL;DR
- Lowe’s and Greenworks sold 554,780 Kobalt-branded yard tools (trimmers, blowers, mowers, chainsaws) with defective lithium-ion batteries capable of short-circuiting and catching fire when charged through the USB-C port.
- Defendants received 34 reports of batteries smoking, sparking, or catching fire but continued selling the tools without warnings or design changes from January 2026 through May 2026.
- The CPSC announced a recall on July 9, 2026, six months after the first sales, affecting tools priced from $20 to $482.
- The recall offers no monetary compensation. Consumers must submit a request to Greenworks for a replacement battery and wait for processing and delivery while unable to safely use the product.
- Plaintiff Robby Yu filed a class action lawsuit in the U.S. District Court for the Northern District of California (Case No. 5:26-cv-7295) alleging violations of California consumer protection laws, breach of implied warranties, and unjust enrichment.
The internal CPSC recall effectiveness study cited in the complaint reveals why this “fix” is designed to fail. That’s in the Legal Receipts section.
The Non-Financial Ledger
Robby Yu bought a Kobalt trimmer from the Lowe’s in Sunnyvale, California on April 13, 2026. He paid $86.70. The packaging told him it was safe for ordinary residential use. The instructions showed him how to charge the battery. The marketing promised reliability and quality. He had no reason to suspect that the lithium-ion battery inside could short-circuit while charging and catch fire.
Robby is one of over half a million people who bought these tools between January and May 2026. Most of them still don’t know their lawn equipment is a fire hazard. Some do. Thirty-four families reported smoke, sparks, or flames to the company before the recall. How many more incidents happened but weren’t reported? How many people noticed something wrong, unplugged the charger, and moved on without realizing they’d narrowly avoided a house fire?
The lawsuit calls this a “latent defect.” That’s legal language for a problem you can’t see until it’s too late. You can’t inspect a lithium-ion battery for a short-circuit risk by looking at the box. You can’t test it in the store. You trust the company to sell you a product that won’t burn your house down. That trust was misplaced.
The CPSC recall notice is cold and bureaucratic. It lists model numbers, dates of sale, and a remedy. It does not list the names of the 34 people who contacted the company after their batteries started smoking. It does not explain why those 34 reports didn’t trigger an immediate halt to sales. It does not calculate how much profit Lowe’s and Greenworks made during the six months they kept selling these tools after the first incident was reported.
The recall “remedy” is a replacement battery. You have to go to Greenworks’ website, find your model number, find your serial number, fill out a form, submit proof of purchase, and wait. Then you wait some more. Meanwhile, the tool you paid for sits unused in your garage because the company told you it’s not safe to operate. You are not compensated for the time you lost. You are not compensated for the alternative arrangements you had to make. You are not compensated for the stress of realizing you brought a fire hazard into your home.
This is a deliberate design choice. The CPSC has known since 2003 that recall compliance drops when companies make the process burdensome and offer no financial incentive. Greenworks and Lowe’s know this too. The harder they make it to get relief, the fewer people will bother, and the more profit they keep.
The lawsuit describes the “disparity in bargaining power” between the defendants and the consumers. That’s a polite way of saying: you had no chance. They knew the batteries were defective. You didn’t. They knew how to hide that fact in marketing language. You didn’t. They knew how many incident reports they’d received. You didn’t. They designed the product, controlled the information, and set the terms. You just wanted a lawn trimmer that worked.
There is a specific cruelty in selling someone a product you know is dangerous and then making them beg for a fix that doesn’t even make them whole. That cruelty is not a bug. It’s the business model.

Societal Impact Mapping
Environmental Degradation
Lithium-ion batteries are marketed as the green alternative to gas-powered yard equipment. No emissions, no oil changes, no trips to the gas station. That narrative collapses when the batteries are defective. A battery that catches fire is not an environmental benefit. It’s a toxic waste event.
When a lithium-ion battery burns, it releases hydrogen fluoride, phosphorus pentafluoride, and other highly toxic gases. These compounds are corrosive to human tissue and dangerous to inhale. A house fire caused by a defective battery doesn’t just destroy property. It contaminates the local environment with chemicals that take years to break down.
The recall does not address what happens to the 554,780 defective batteries once they’re replaced. Where do they go? Are they disposed of safely, or do they end up in landfills where they can leach toxic metals into soil and groundwater? The complaint does not ask this question because the law does not require companies to account for the environmental cost of their defects. They should.
Public Health
Thirty-four reports of smoking, sparking, or catching fire. That’s 34 families who had to evacuate, call 911, or frantically unplug a charger before it got worse. That’s 34 near-misses. The lawsuit states that no injuries have been reported, but that’s not the same as no harm. Psychological harm counts. The fear of a house fire counts. The disruption to your daily life counts.
Lithium-ion battery fires are notoriously difficult to extinguish. They burn hotter than traditional fires and can reignite even after being put out. Firefighters need specialized training and equipment to handle them. Homeowners do not have that training. If your Kobalt trimmer battery catches fire in your garage, you are not equipped to deal with it safely.
The public health impact extends beyond the 34 reported incidents. There are over 554,000 of these tools in circulation. How many of them are still being used by people who never saw the recall notice? How many are sitting in garages, plugged in, waiting for the next short-circuit? The defendants do not have an answer to this question because they did not design a recall system that prioritizes public safety. They designed one that minimizes their liability.
Economic Inequality
The price range for these tools was $20 to $482. That’s not pocket change for most people. For someone buying a $20 trimmer, that might be their entire lawn care budget for the year. For someone buying a $482 mower, that’s a significant household investment. The recall offers no refund. It offers a replacement battery you have to request and wait for. That’s not economic justice. That’s economic extraction.
The people most harmed by this defect are the people least able to absorb the cost. If you can afford to buy a second trimmer while you wait for the replacement battery, you’re fine. If you can’t, you’re stuck. You can’t return the product for a refund. You can’t sell it secondhand without disclosing the defect. You can’t even safely use it. Your money is locked in a product that doesn’t work, and the company that took your money is offering you a bureaucratic process as compensation.
This is wage theft by another name. You worked for that $86.70. You exchanged your labor for a product you believed was safe and functional. The company knew it wasn’t. They took your money anyway. The fact that this is legal does not make it just.
The “Cost of a Life” Metric
What Now?
The class action lawsuit is Case No. 5:26-cv-7295 in the U.S. District Court for the Northern District of California. It was filed on July 15, 2026 by Robby Yu on behalf of all purchasers of the recalled Kobalt tools. The defendants are Lowe’s Companies, Inc. (incorporated in North Carolina, headquartered in Mooresville, NC) and Greenworks North America, LLC (organized under North Carolina law, headquartered in Mooresville, NC).
The lawsuit alleges violations of California’s Unfair Competition Law (Cal. Bus. & Prof. Code Β§Β§ 17200 et seq.), California’s False Advertising Law (Cal. Bus. & Prof. Code Β§Β§ 17500 et seq.), California’s Consumers Legal Remedies Act (Cal. Civ. Code Β§Β§ 1750 et seq.), breach of implied warranties, and unjust enrichment.
If you purchased a Kobalt 24V or 48V yard tool with a USB-C battery between January 2026 and May 2026, check the CPSC recall notice to see if your model is affected. The affected model numbers include: KPC 3024-06, KB 324-06, KB 324D-06, KB 624-06, KB 624D-06, KOC 4248-06, KHB 6048-06, KMS 1524-06, KCS 1448-06.
Do not use the tool until you have confirmed it is not affected or have received a replacement battery. Document your purchase with receipts, photos, and any correspondence with Lowe’s or Greenworks.

Organize: Contact consumer protection advocacy groups in your area. Share recall information with neighbors, family, and community groups. Demand that your elected representatives strengthen recall enforcement laws. Support legislation that mandates full refunds for defective products, not just replacement parts.
Resist: Stop buying from companies that treat recalls as damage control instead of public safety obligations. Publicly call out corporate executives and board members who prioritize profit over safety. Name them. Document their decisions. Make it impossible for them to hide behind corporate anonymity.
