What Is the Sierra Mist Lawsuit?
The Sierra Mist lawsuit refers to multiple legal actions and disputes tied to PepsiCo’s decision to discontinue Sierra Mist in January 2023 and replace it with a new lemon-lime soda called Starry.
There are two distinct legal threads at the center of this story:
- The Cierra Mistt trademark dispute – a viral claim that a TikTok influencer forced PepsiCo to kill Sierra Mist
- Consumer protection and false advertising claims – allegations that PepsiCo misled buyers during and after the rebrand
Understanding the difference between these two threads is critical before drawing any legal conclusions.
The Cierra Mistt Trademark Story: Viral Claim vs. Legal Reality
In early 2023, TikTok creator Cierra Mistt claimed that PepsiCo had sent her a cease-and-desist letter over her online name, alleging it was confusingly similar to the Sierra Mist brand. She hinted, without providing documentation, that she had won a legal battle against the soda giant and that the conflict had been “amicably resolved.”
The story spread rapidly. Millions believed that a social media influencer had single-handedly forced one of the world’s largest beverage companies to rename its product.
Sierra Mist is gone because it was losing to Sprite, not because a TikTok creator outsmarted PepsiCo’s legal team.
The legal reality is far less dramatic. As of February 2026, no verified lawsuit between PepsiCo and Cierra Mistt has been confirmed in any public court record. There are no court filings, no docket numbers, and no USPTO opposition proceedings to support her claims. PepsiCo still holds a valid federal trademark registration for Sierra Mist, confirmed through the USPTO database.
What likely happened is standard trademark enforcement, a cease-and-desist letter was sent due to potential consumer confusion from the similar names. That is not a lawsuit. It is not a loss. It is routine brand protection.
Why PepsiCo Really Discontinued Sierra Mist
The Sierra Mist lawsuit narrative often overshadows the straightforward business reason behind the discontinuation.
Sierra Mist held less than 1% of the lemon-lime soda market when PepsiCo officially pulled the plug in 2023. Despite several rebranding attempts, including renaming it to Mist Twist from 2016 to 2018, the product never threatened Sprite’s dominance.
PepsiCo launched Starry as a replacement targeting Gen Z consumers, with a stronger citric acid flavor profile and modern branding. The decision was driven entirely by market performance, not legal pressure from an influencer.
The Real Legal Claims: Consumer Protection and False Advertising
While the Cierra Mistt story is largely debunked, there are legitimate legal concerns surrounding PepsiCo’s handling of the Sierra Mist to Starry transition.
False Advertising and “Natural Flavor” Claims
One of the most substantive allegations in the Sierra Mist lawsuit involves PepsiCo’s marketing of Sierra Mist as a soda made with “natural flavors.” Plaintiffs argue the product contained synthetic citric acid and lab-created ingredients, making the “natural” claim potentially misleading under U.S. consumer protection law.
These claims have been raised in preliminary state-level cases in:
- California
- New York
- Illinois
- Florida
If proven, these allegations could constitute violations of state unfair trade practice statutes.
Deceptive Rebrand Marketing
A separate but related legal concern centers on how PepsiCo marketed Starry during the transition. Consumers allege that:
- PepsiCo failed to clearly communicate that Sierra Mist was being permanently discontinued
- Marketing initially positioned Starry as a natural evolution of Sierra Mist
- Retailers placed Starry on the same shelf locations as Sierra Mist, causing unintentional purchases
These claims argue that consumers were misled into buying a product they did not choose.

Flavor Profile Disappointment as a Legal Argument
Some plaintiffs have gone further, arguing that the significant flavor difference between Starry and Sierra Mist, including altered sweetener ratios, constitutes a form of consumer fraud. While this is a harder legal argument to sustain, it has gained traction in consumer complaint filings.

Sierra Mist Lawsuit – Full Legal Timeline (2023–2026)
January 2023
PepsiCo officially discontinues Sierra Mist and launches Starry. No public legal action at this stage. The decision is driven purely by market performance, with Sierra Mist holding under 1% of the lemon-lime soda category.
Mid-2023
TikTok creator Cierra Mistt goes viral claiming PepsiCo sent her a cease-and-desist letter over her online name. The story spreads widely, but no verified court records support a formal lawsuit ever being filed.
2023–2024
Consumer advocacy groups in California, New York, Illinois, and Florida begin filing formal complaints with state attorneys general, targeting PepsiCo’s use of “natural flavors” labeling on Sierra Mist.
November 2025
Chicago resident Maria Martinez files an initial federal complaint in the Northern District of Illinois, seeking to represent all U.S. consumers who purchased Sierra Mist between January 2018 and December 2023. The lawsuit alleges PepsiCo violated federal and state consumer protection laws by marketing Sierra Mist as containing “natural flavors” when key ingredients were synthetically produced.
January 2026
PepsiCo files a motion to dismiss, arguing its “natural flavor” claims fully comply with FDA definitions and that no consumer protection statute was violated.
February 2026
Plaintiffs file an amended complaint, expanding the claims to include additional state-level consumer protection violations across four states.
March 2026
Key development: The court denies PepsiCo’s motion to dismiss on the primary claims, allowing the case to proceed to discovery. This is a significant milestone. It signals the court found the plaintiffs’ natural flavor arguments legally plausible enough to move forward.
June 2026 (Upcoming)
A class certification hearing is scheduled in the Northern District of Illinois. If the court grants certification, the case officially becomes a class action representing millions of consumers nationwide.
Late 2026 – Early 2028 (Projected)
Legal experts expect discovery to continue through summer 2026. Settlement negotiations, if any, are not expected to begin before late 2026 or early 2027. A final resolution, whether by court ruling or settlement, is projected for late 2027 to early 2028.
Step-by-Step – How to Protect Your Claim Right Now
Step 1 – Document your purchases
Gather any receipts, bank or credit card statements, or grocery loyalty program records showing you bought Sierra Mist between January 2018 and December 2023. No receipt is required to eventually file, but records strengthen your claim considerably.
Step 2 – File a consumer complaint now
Submit a complaint to your state attorney general’s office. California, New York, Illinois, and Florida residents are particularly relevant, as active investigations are already underway in all four states. You do not need a lawyer to do this and it takes under ten minutes online.
Step 3 – Monitor class action databases
Watch Top Class Actions (topclassactions.com) and Open Class Actions (openclassactions.com) for updates. Once a class is certified, a claims administrator will open a formal filing window. You do not need an attorney to file a claim and filing is always free.
Step 4 – Watch the June 2026 certification hearing
The class certification hearing in the Northern District of Illinois is the single most important event in this case right now. If granted, the lawsuit formally becomes a nationwide class action and a claims window will follow. This is the update to watch before anything else.
Step 5 – Consult a consumer protection attorney
If you purchased Sierra Mist in significant quantity between 2018 and 2023, or relied on the “natural flavors” marketing when making buying decisions, a free consultation with a consumer protection attorney can clarify whether you qualify as a named plaintiff. Named plaintiffs receive an additional incentive award of $5,000 to $15,000 on top of any regular claim payout.
Can You Get Money from the Sierra Mist Lawsuit? Settlement Estimates Explained
As of June 2026, PepsiCo has not issued any settlement offers. The case is still in discovery. However, understanding how settlements in similar consumer protection cases work gives you a realistic picture of what compensation could look like if the case resolves in plaintiffs’ favour.
Over 47 million Americans purchased Sierra Mist in its final year before the 2023 discontinuation. If even a fraction of those buyers qualify as class members, the total fund could be substantial. Legal analysts have noted that with over 100 million units potentially subject to scrutiny under false advertising claims, total liability could reach into the hundreds of millions, though actual individual payouts in consumer food labeling cases are typically far more modest.
Here is how similar settled cases have looked:
| Case | Claim Type | Settlement | Average Per Consumer |
|---|---|---|---|
| Coca-Cola Vitaminwater (2009) | Misleading health claims | $61 million | $5–$20 |
| Red Bull “Gives You Wings” (2014) | False advertising | $13 million | $10–$15 |
| Kraft Mac & Cheese Labels (2023) | Natural flavor mislabeling | Pending | TBD |
| Sierra Mist (Projected) | Natural flavor and consumer fraud | No settlement yet | Estimated $5–$25 if class action is certified and settled |
Important: Attorney fees typically consume 25% to 33% of the total settlement fund before any money reaches claimants. Named plaintiffs who serve as class representatives usually receive an additional incentive award of $5,000 to $15,000 for their role in the case.
What Consumers Can Do If They Were Affected
If you purchased Sierra Mist between 2020 and 2023, particularly based on “natural flavor” marketing claims, you may have standing to participate in future legal action.
Steps you can take right now:

- File a consumer complaint with your state attorney general’s office
- Monitor class action databases such as Top Class Actions for updates on certified cases

Key Takeaways
- The Sierra Mist lawsuit is not a single case. It involves multiple legal threads including a federal class action, state-level false advertising investigations, and consumer fraud complaints across four states.

- The most credible ongoing legal claims involve false advertising around “natural flavor” labeling on Sierra Mist products sold between 2018 and 2023.
- No court ruling and no settlement has been issued yet. Individual payouts, if a settlement is reached, are projected in the $5 to $25 range based on comparable cases.
- Consumers who purchased Sierra Mist between 2018 and 2023 may have potential legal standing. No claim form is open yet, but documenting purchases and filing a state attorney general complaint now is recommended.
Conclusion
The Sierra Mist lawsuit is part viral myth, part real legal concern. The TikTok story about Cierra Mistt forcing PepsiCo to rebrand has no verified legal basis, but the consumer protection claims around false advertising and misleading marketing are legitimate and still developing in 2026.
For consumers who purchased Sierra Mist between 2020 and 2023, it is worth monitoring class action updates and consulting a consumer protection attorney if needed. For businesses, this case is a clear reminder, how you exit a product matters just as much as how you launch one. Poor communication during a rebrand can lead to serious legal exposure. The Sierra Mist lawsuit is far from over. Stay informed, know your rights, and watch this space.
FAQ’s
Did PepsiCo lose the Sierra Mist trademark lawsuit to Cierra Mistt?
No. There is no verified court record of a formal lawsuit ever being filed. PepsiCo still owns the Sierra Mist trademark as confirmed by the USPTO in February 2026. A cease-and-desist letter was likely sent, but that is not a lawsuit.
Why did Sierra Mist get discontinued?
PepsiCo discontinued Sierra Mist in January 2023 due to poor market performance. The soda held less than 1% market share in the lemon-lime soda category. Starry was launched as its Gen Z-focused replacement.
Is there an active class action lawsuit against PepsiCo over Sierra Mist?
As of 2026, no class action has been officially certified. However, preliminary filings and state attorney general complaints exist, particularly around false advertising and natural flavor labeling claims.
Can I still file a claim related to the Sierra Mist lawsuit?
Potentially. If you purchased Sierra Mist between 2020 and 2023 and relied on “natural flavor” marketing, you may qualify. Consult a consumer protection attorney or monitor class action filing sites for updates.
What is the difference between a cease-and-desist letter and a lawsuit?
A cease-and-desist letter is a written demand asking someone to stop a specific action. It is not a legal filing and does not indicate a lost lawsuit. A lawsuit requires formal court filings, docket numbers, and judicial involvement.
Can I get money from the Sierra Mist lawsuit?
Not yet. As of June 2026, no settlement fund exists and no claim form is open. The federal class action in Illinois is still in discovery, with a class certification hearing scheduled for June 2026. If the court certifies the class, a formal claims process will open, likely in late 2026 or 2027. Monitor Top Class Actions and Open Class Actions for updates. Filing will be free and will not require an attorney.
How much could the Sierra Mist settlement pay out?
No settlement has been offered yet. Based on comparable consumer food labeling cases, such as the Coca-Cola Vitaminwater settlement of $61 million and the Red Bull false advertising settlement of $13 million, individual payouts in class actions of this type typically range from $5 to $25 per person after attorney fees are deducted. Named class representatives can receive an additional $5,000 to $15,000 incentive award on top of that.
What was PepsiCo’s motion to dismiss and why does it matter?
In January 2026, PepsiCo asked the federal court to throw out the case entirely, arguing its “natural flavor” labeling complied with FDA definitions. In March 2026, the court denied that motion on the primary claims. This means the judge found the plaintiffs’ arguments legally plausible enough to deserve a full hearing. This is a significant win for consumers. The case is now moving into the discovery phase, where both sides gather evidence, take depositions, and build their arguments ahead of the class certification decision.
