Misleading Advertising Examples: 8 Real Cases (2026)

A misleading ad is any ad that creates a false impression in the mind of a reasonable buyer, whether through a false claim, a claim with no proof behind it, or a technically true claim that hides the part that matters. In the US the Federal Trade Commission (FTC) polices it. In the UK the Advertising Standards Authority (ASA) does. The cases below are real, documented, and mostly expensive.

What counts as a false or misleading ad

The FTC's test is practical. An ad is deceptive if it contains a statement, or leaves out information, that is likely to mislead a reasonable consumer and that matters to the buying decision. Intent does not enter into it. A brand that believed its own claim can still lose.

Three patterns show up again and again in enforcement:

• Claims with no evidence. The ad says the product does something and the company cannot show it. Health and fitness claims live here.
• Claims that are flatly false. The product does not do what the ad says, and the company knew or should have known.
• Hidden connections and manufactured proof. A paid endorsement dressed up as an opinion, or a five-star review nobody earned.

Every example below fits one of those three buckets, and the lesson attached to each one is the part worth stealing.

Quick scan of the cases

Volkswagen's "Clean Diesel" campaign

This is the biggest false advertising case on record, and the ads were slick. Volkswagen sold or leased more than 550,000 diesel cars between late 2008 and late 2015, using Super Bowl spots, social media and print aimed at environmentally conscious buyers. The FTC's March 2016 complaint said the marketing promised low emissions, including a 90 percent cut in nitrogen oxides, while the cars carried illegal defeat devices and emitted up to 4,000 percent more than the legal limit of that pollutant.

The money followed. In June 2016 the company agreed to spend up to $14.7 billion across two settlements, one with the US government and California and one with the FTC, as the Department of Justice announced. In 2020 the FTC reported that Volkswagen had repaid more than $9.5 billion to buyers who were deceived by the campaign.

The lesson: a values-based claim ("clean", "green", "sustainable") is a factual claim the moment you attach a number to it. Marketing cannot launder a product fact.

Skechers Shape-ups and the toning shoe boom

Toning shoes were close to a billion-dollar category at the 2010 peak, and Skechers owned most of it. Its ads said Shape-ups and related lines such as Resistance Runner, Toners and Tone-ups would help people lose weight and strengthen and tone their buttocks, legs and abdominal muscles. Celebrity endorsers, including a Kim Kardashian Super Bowl spot in 2011, carried the message.

In May 2012 Skechers agreed to pay $40 million to settle the FTC's charges, and the FTC's announcement noted that the claims lacked scientific backing. Refunds went to buyers through the FTC or a court-approved class action.

The lesson: a famous face does not move the legal burden. The advertiser still owns the claim.

Kellogg's Rice Krispies immunity claim

In 2010 the packaging said Rice Krispies "now helps support your child's immunity" and highlighted a 25 percent Daily Value of antioxidants and nutrients, including vitamins A, B, C and E. The FTC found the immunity claim unsubstantiated.

No fine came out of it. What did: an expanded order that forbids Kellogg from making health-benefit claims about any food unless scientific evidence backs them. Per the FTC's release, it was the company's second FTC action in a year, after the earlier Frosted Mini-Wheats case.

That is the quieter cost of a misleading ad. A repeat offender gets an order that covers the whole product line, and every future claim now needs a file of evidence.

Red Bull gives you wings

Everyone's favorite example, and the one people get slightly wrong. Red Bull never lost a trial. A class action filed in January 2013 in federal court in New York argued the slogan implied the drink improved performance and concentration. In 2014 the company settled for more than $13 million, offering eligible US buyers either a $10 reimbursement or two free products, and it denied wrongdoing, as SBS reported.

A private class action drove this one. Class actions over ad claims are a real cost center for consumer brands, and settling is often cheaper than winning.

The lesson: puffery (obvious exaggeration nobody takes literally) has limits, and a slogan that sits next to implied performance claims in your other ads can get dragged into court.

POM Wonderful and the disease claims

POM Wonderful sold pomegranate juice and ran ads implying it treated, prevented or reduced the risk of heart disease, prostate cancer and erectile dysfunction. The FTC concluded the company lacked sufficient evidence, and the D.C. Circuit upheld that finding on January 30, 2015, rejecting a First Amendment defense, according to Holland & Knight's summary.

POM had studies. The problem was how it used them. The ads touted results without noting the limits of those studies or the existence of conflicting evidence. The court did trim the FTC's remedy, ruling the agency went too far by requiring two randomized controlled trials for future claims instead of one.

The lesson: cherry-picked proof is still misleading proof. A study only substantiates a claim if the ad reflects what it found.

Beauty filters on tanning ads

Misleading ads do not need a false sentence. In February 2021 the ASA ruled against Instagram Stories ads for tanning products from Skinny Tan and We Are Luxe. In both, influencers used a filter that deepened their skin tone while promoting the tan. The ASA decided the filter was directly relevant to the product's purpose, so it exaggerated the result and the ads misled, as its guidance on the rulings explains.

Creators are the ones holding the phone in UGC-style content, which makes this ruling especially relevant. The visual itself is the claim. If the product's job is to change how skin looks, a filter on the demo is a false demo.

The lesson: before and after footage needs to be real, unfiltered, and shot under comparable lighting.

Hidden paid endorsements on Instagram

In April 2017 FTC staff sent more than 90 letters to influencers and marketers reminding them to clearly disclose relationships with brands. It was the first time the agency contacted influencers directly. The letters pointed out that mobile users usually see only the first three lines of a long caption, so disclosures belong above the "more" button, and that tags like "#sp", "#partner" or "Thanks [Brand]" may not read as advertising to many viewers.

The FTC's current guidance, Disclosures 101 for Social Media Influencers, covers the details: a material connection includes payment, free product, or a family or business relationship, and the disclosure has to be clear and conspicuous.

The lesson: if money or merchandise changed hands, say so in plain words, early, in the same medium as the endorsement. For video, put it on screen and in the audio, and keep it out of the description box.

Fake reviews and AI-generated testimonials

The fastest-moving area right now. On August 14, 2024 the FTC announced a final rule banning fake reviews and testimonials, including AI-generated ones, along with review gating that pays for a particular sentiment, undisclosed insider reviews, and the sale of fake social media metrics. It lets the agency seek civil penalties from knowing violators.

A month later, in September 2024, the FTC launched Operation AI Comply. One target was Rytr, an AI writing tool with a "Testimonial & Review" feature that let subscribers generate large volumes of detailed reviews from thin input. The FTC said many contained specifics that had no relation to what the user entered. Another case, DoNotPay, ended in a $193,000 settlement over claims that its chatbot could stand in for a lawyer without testing to back that up. The Commission voted 3-2 on Rytr and 5-0 on DoNotPay.

The lesson: AI changes how fast an ad gets made. It does not change who is responsible for what it says.

What the cases have in common

Read the eight stories side by side and the pattern is boring in a useful way.

Every one started with a claim that sounded like a fact. Immunity support. Weight loss. Low emissions. Disease prevention. Improved results. A real review. Each time, someone asked for the evidence, and the file was thin.

None of the ads were hard to spot as a risk in hindsight. The warning signs were all visible at the creative review stage: a number with no source, a before and after nobody could reproduce, a testimonial with no real customer attached.

A pre-flight check for your own ads

Before an ad goes live, run it through these questions. They take about five minutes.

1. Find the claims. Highlight every sentence that states or implies a result, a number, a comparison or a guarantee.
2. Attach a source to each one. A study, a lab report, internal test data, a customer record. If you cannot attach one, cut the claim or soften it to what you can prove.
3. Check the visuals. Filters, retouching and staged results count as claims. A demo should look like what the buyer will get.
4. Check the people. Real customers need to have used the product. Paid creators and gifted product need a plain disclosure at the start.
5. Check the fine print. Disclaimers should sit next to the claim they qualify. A footnote that contradicts the headline does not rescue it.
6. Keep the file. Store the evidence with the ad version. When a platform reviewer or regulator asks, you answer in an hour instead of a week.

Where UGC-style ads fit

UGC-style creative works because it looks like a real person talking. That is also why it needs more care. A synthetic presenter delivering a script is still an advertiser making claims, and the same rules apply as they would for a human creator reading from a brief.

If you build ads this way, write the script from your evidence file first, and keep testimonials to claims a real customer could make. A platform like EzUGC's AI UGC video generator turns a script into a finished video, which makes it easy to produce many variations quickly, and the checklist above is how you keep every one of them clean. For hooks that grab attention without overpromising, the AI hook generator is a useful starting point, and how to write UGC ad scripts for ecommerce goes deeper on scripting. Plans start at $99 a month for up to 50 videos on the pricing page.

The takeaway

Big brands with legal teams got caught because the gap between the claim and the proof was wide and nobody closed it. A small brand has the same exposure with less money to settle.

The cheapest compliance step is also the most effective one. Write down what your ad promises, write down how you know, and publish only the claims where those two sentences match.
