Demand Letter for a Defective Product: Get Your Money Back

You bought something that was supposed to work. It didn't. Maybe it broke after a week. Maybe it was dead on arrival. Maybe it slowly deteriorated in a way that screams manufacturing defect. Whatever the specifics, the company that sold it to you isn't making it right — and now you're stuck with a useless product and a lighter wallet.

A demand letter is your next move. It's a formal written notice that puts the company on record, establishes your legal rights, and creates a paper trail for court if needed. Most importantly, it works: companies that ignore verbal complaints suddenly pay attention when they receive a formal demand with legal citations.

When to Send a Demand Letter for a Defective Product

Before drafting your letter, make sure you've taken the basic steps first. You should have already attempted to resolve the issue through the company's normal channels — customer service, returns department, warranty claims. If those efforts failed or were ignored, a demand letter is appropriate.

Specifically, send a demand letter when:

• The company denied your warranty claim without a valid reason
• Customer service is giving you the runaround — endless transfers, broken promises, or ghosting
• The product caused additional damage to your property or person
• The return window closed but the product was defective from the start
• The company offered an inadequate remedy like store credit when you deserve a full refund

Your Legal Rights: More Powerful Than You Think

Most consumers don't realize how much legal protection they actually have. There are three layers of law working in your favor:

1. Express Warranties

Any written warranty, product description, advertising claim, or verbal promise by the seller creates an express warranty. If the product doesn't match what was promised, the warranty is breached — period. This includes product packaging claims, online product descriptions, and marketing materials.

2. Implied Warranties (UCC)

Under the Uniform Commercial Code (adopted in all 50 states), every product sale comes with two implied warranties:

• Warranty of Merchantability: The product must be fit for its ordinary purpose. A toaster must toast. A phone must make calls. A washing machine must wash clothes without flooding your house.
• Warranty of Fitness for a Particular Purpose: If the seller knew you needed the product for a specific use and recommended it, the product must work for that use.

These warranties exist even if the product has no written warranty. Some manufacturers try to disclaim implied warranties, but the Magnuson-Moss Warranty Act limits when they can do this.

3. State Consumer Protection Laws

Every state has consumer protection or "unfair and deceptive acts and practices" (UDAP) laws. Many of these include:

• Treble damages (triple your actual losses)
• Statutory minimum damages (often $200-$1,000 even for small claims)
• Attorney's fees paid by the defendant
• No requirement to prove intent — the company doesn't need to have deliberately deceived you

These penalties give you significant leverage. When a company realizes they could face triple damages plus attorney's fees, a simple refund starts looking very attractive.

What to Include in Your Demand Letter

Your letter needs to be clear, factual, and specific. Here's what to include:

Product Information

• Exact product name, model number, and serial number
• Where and when you purchased it
• Purchase price (attach receipt)
• Any warranty or guarantee documentation

Description of the Defect

• What happened — specific, factual, chronological
• When you first noticed the problem
• How the product fails to meet its advertised or expected performance
• Any safety hazards the defect creates

Your Attempts to Resolve

• Dates you contacted the company
• Who you spoke with (names, reference numbers)
• What they said or offered
• Why their response was inadequate

Your Damages

• Purchase price of the defective product
• Cost of any repairs you attempted
• Property damage caused by the defect
• Replacement costs or price difference for a comparable product
• Incidental costs (shipping, inspection, time off work)
• Personal injury expenses if applicable

Your Legal Basis

Cite the specific laws that support your claim:

• UCC § 2-314 (implied warranty of merchantability)
• UCC § 2-315 (warranty of fitness for particular purpose)
• Magnuson-Moss Warranty Act, 15 U.S.C. § 2301
• Your state's consumer protection statute (cite by name and section)

Your Demand

• Exactly what you want: full refund, replacement, or repair
• The dollar amount of additional damages
• A specific deadline (14-30 days is standard)
• What you'll do if they don't comply (small claims court, state AG complaint, FTC complaint)

Sample Demand Letter Structure

Here's a framework you can follow:

[Your Name and Address]

[Date]

[Company Name and Address]

Re: Defective [Product Name], purchased [Date], Order/Receipt #[Number]

Dear [Company/Customer Service Manager],

On [date], I purchased [product] from [retailer/website] for $[amount]. The product is defective: [describe defect in 2-3 sentences].

I contacted your company on [dates] and spoke with [names]. [Describe their response and why it was inadequate].

Under [state consumer protection law] and the implied warranty of merchantability (UCC § 2-314), this product must function as reasonably expected. It does not. I am also protected under the Magnuson-Moss Warranty Act.

I demand [full refund of $X / replacement / specific remedy] within [14/30] days of this letter. If I do not receive a satisfactory response, I will [file in small claims court / file a complaint with the state Attorney General / pursue all available legal remedies].

[Your signature]

Tips That Make Your Letter More Effective

Send It to the Right Person

Don't send your demand letter to "Customer Service" — find the name of the CEO, General Counsel, or VP of Customer Experience. Letters addressed to specific executives get faster responses. Check the company's SEC filings, LinkedIn, or press releases for names.

CC the Right Agencies

At the bottom of your letter, add: "CC: [State] Attorney General's Office, Federal Trade Commission, Better Business Bureau." You don't actually need to have filed complaints yet — but the company doesn't know that, and the implied threat of regulatory attention is powerful.

Keep It Professional

Angry letters get ignored. Professional letters with legal citations get resolved. Stick to facts, cite laws, and state your demands clearly. The goal is to make it obvious that settling with you is cheaper than fighting you.

Send via Certified Mail

Always send your demand letter via USPS certified mail with return receipt requested. This proves the company received your letter and starts the clock on your deadline. Keep the green receipt card — you'll need it if you go to court.

What Happens After You Send the Letter

After sending your demand letter, one of three things typically happens:

1. The company complies. They send a refund, replacement, or agree to repair. This happens more often than you'd expect — especially when you've cited specific laws and penalties.
2. The company negotiates. They offer a partial refund or alternative resolution. Consider whether it's reasonable before accepting or pushing further.
3. The company ignores you or refuses. This is where your paper trail becomes critical. File in small claims court (no lawyer needed for amounts under your state's limit, typically $5,000-$10,000), file complaints with the state AG and FTC, and leave honest reviews on consumer sites.

Special Situations

Products Purchased Online

If you paid by credit card, you have an additional weapon: the chargeback. Under the Fair Credit Billing Act, you can dispute charges for products that weren't delivered as described. File the chargeback AND send the demand letter — the dual pressure is very effective.

Products That Caused Injury

If the defective product caused personal injury, your claim is significantly larger and may warrant consulting a personal injury attorney. Many offer free consultations and work on contingency. You should still send a demand letter, but be aware that injury claims involve different legal theories (strict product liability, negligence) and potentially much larger damages.

Class Action Potential

If you suspect the defect affects many consumers, check classaction.org and search for existing lawsuits against the manufacturer. You may be able to join an existing class action or your complaint could help establish one. Also check the CPSC (Consumer Product Safety Commission) for any recalls.

State-Specific Consumer Protection Laws

Your state's consumer protection law is one of your most powerful tools. Here are some of the strongest:

• California: Consumer Legal Remedies Act (CLRA) — no cap on damages, attorney's fees available
• Massachusetts: Chapter 93A — treble damages, attorney's fees, very consumer-friendly
• New York: General Business Law § 349 — $50 statutory minimum, no need to prove reliance
• Texas: DTPA — treble damages for knowing violations, no class action waiver
• Illinois: Consumer Fraud and Deceptive Business Practices Act — broad definition of fraud
• Florida: FDUTPA — actual damages plus attorney's fees

Look up your state's specific statute before writing your demand letter. Naming the exact law and section number makes your letter far more credible.

The Bottom Line

Companies count on consumers giving up. They make the return process frustrating, the warranty claims Byzantine, and the customer service phone trees endless — all betting that you'll eventually shrug and eat the loss. A demand letter breaks that cycle. It tells the company, in formal legal terms, that you know your rights, you have evidence, and you're willing to take this further.

Most of the time, that's enough. Companies don't want small claims court appearances, AG complaints, or negative press. They want the problem to go away quietly. Your demand letter gives them a clean way to make it right — and a clear picture of what happens if they don't.

Key Takeaways

• You have legal rights under both warranty law and state consumer protection statutes when a product fails
• Document the defect thoroughly with photos, videos, and a written timeline before sending your letter
• Most states have consumer protection laws with penalties that exceed the product's value, giving you leverage
• Always send your demand letter via certified mail to create a legal paper trail
• Give the company a specific deadline (typically 14-30 days) to respond before escalating
