New Class Action Roundup: Google Bricked Nest Thermostats, Petco Dog Food Lawsuit, and a Lemon Perfect Labeling Dispute

Three new class action lawsuits filed in early April 2026 target a range of consumer products — from smart home devices to pet food to flavored water. Each case alleges that a major company misled buyers or deprived them of something they reasonably expected when they made a purchase. Here's what you need to know.

1. Google Nest Learning Thermostat — Remote Feature Removal

Filed: April 2026

Who May Qualify: Consumers who purchased first- or second-generation Nest Learning Thermostats

Estimated Payout: Not yet determined

According to a recent class action filing, Google allegedly "bricked" first- and second-generation Nest Learning Thermostats by remotely disabling features that consumers had already paid for. The lawsuit alleges that Google stripped functionality from these devices without adequate notice or compensation, effectively rendering the thermostats significantly less useful than they were at the time of purchase.

The complaint claims that buyers reasonably expected their Nest thermostats to continue functioning as advertised, and that Google's decision to remotely degrade these devices constituted an unfair business practice. According to the lawsuit, affected consumers were left with a diminished product and no meaningful remedy from the company.

Consumers who purchased first- or second-generation Nest Learning Thermostats may be eligible to participate in the litigation. No settlement has been announced; the case is in early stages.

2. Petco WholeHearted Grain-Free Dog Food — Alleged Heart Disease Link

Filed: April 2026

Who May Qualify: Consumers who purchased Petco's WholeHearted grain-free dog food products

Estimated Payout: Not yet determined

A new class action lawsuit accuses Petco Health and Wellness of falsely advertising its WholeHearted brand grain-free dog food as a healthy choice for pets. The lawsuit alleges that Petco's marketing obscured a potential link between grain-free diets and dilated cardiomyopathy (DCM), a serious and potentially fatal heart condition in dogs.

The complaint claims that had consumers known about this alleged risk, they would not have purchased the products — or would have paid substantially less for them. The lawsuit does not appear to allege that every pet was harmed, but rather that the marketing claims were misleading in light of available scientific information. Studies have suggested a possible association between grain-free diets and DCM in dogs, and the U.S. Food and Drug Administration has previously investigated the issue, though research into the connection remains ongoing.

Pet owners who purchased WholeHearted grain-free dog food from Petco may be eligible to participate in the lawsuit. The case is in its early stages and no settlement has been reached.

3. Lemon Perfect — "No Artificial Sweeteners" Labeling Dispute

Filed: April 2026

Who May Qualify: Consumers who purchased Lemon Perfect flavored water products

Estimated Payout: Not yet determined

A class action lawsuit filed against Lemon Perfect alleges the company falsely labeled its beverage products as containing "no artificial sweeteners." According to the complaint, Lemon Perfect drinks actually contain stevia leaf extract — which the lawsuit characterizes as an artificial sweetener, despite the ingredient's common marketing as a natural alternative.

The plaintiff claims this labeling misled consumers who were specifically seeking products free from sweeteners of any kind. According to the complaint, had buyers known the products contained stevia, they would not have made the purchase — or would have paid a lower price. The lawsuit raises questions about the increasingly common practice of marketing stevia-containing products as "natural" or free of artificial ingredients.

Whether stevia is classified as "natural" or "artificial" has been a point of ongoing debate among food scientists and regulators. The FDA has granted stevia derivatives "Generally Recognized as Safe" (GRAS) status, though labeling standards around the term "no artificial sweeteners" are not uniformly defined.

Consumers who purchased Lemon Perfect products may be eligible to participate in the class action. The case is newly filed and no settlement has been announced.

Key Takeaways

• Remote software updates can carry legal risk. The Nest lawsuit highlights a growing area of litigation: consumers alleging that tech companies degrade products after purchase by removing features through software changes.
• "Healthy" food claims remain a litigation hotspot. Both the Petco and Lemon Perfect cases involve marketing language — "grain-free" and "no artificial sweeteners" — that plaintiffs argue was misleading, even if technically defensible.
• No proof of purchase may be required. Class actions involving widely sold consumer products sometimes allow claims without receipts, though eligibility requirements vary by case. Follow each settlement's specific instructions if and when claims processes open.
• These cases are newly filed. None of the three lawsuits above have resulted in settlements. Consumers interested in staying informed should monitor case developments before taking action.
• Only an attorney can determine eligibility. If you believe you may be affected by any of these cases, consulting a qualified attorney is the appropriate next step.
