Defective Products in France: Repair, Replacement, or Refund

When a newly purchased product breaks down, presents a manufacturing defect, or does not match what was promised, disappointment quickly gives way to a pragmatic question: what are my rights? Under French law, consumers are highly protected against professional sellers thanks to a robust legislative arsenal. Whether you bought the latest smartphone, a household appliance, or even a vehicle, you are not left helpless. This comprehensive guide explains how to navigate between repair, replacement, and refund, so you can assert your rights effectively and without stress.

The Legal Framework: The Three Consumer Guarantees

To know if you can demand a repair, replacement, or refund, you must first identify the legal basis of your claim. French law distinguishes between three major guarantees.

1. The Legal Guarantee of Conformity: The Primary Shield

This is the ultimate guarantee for consumers. Governed by Articles *L. 217-3 et seq. of the Code de la consommation*** (French Consumer Code), it applies mandatorily to all tangible consumer goods (new or second-hand) sold by a professional to an individual.

• What it covers: The product must conform to the seller's description, be fit for the purpose usually expected of similar goods, and possess the qualities presented at the time of sale.
• The presumption of defect: For new goods purchased since January 1, 2022, any defect that appears within a period of 2 years (24 months) from delivery is presumed to have existed at the time of purchase. You do not have to prove that the defect existed beforehand; it is up to the seller to prove otherwise if they contest it. For second-hand goods, this presumption period is 12 months.

2. The Legal Guarantee Against Hidden Defects: For Serious and Invisible Flaws

Governed by Articles *1641 to 1649 of the Code civil*** (French Civil Code), this guarantee applies to all goods (moveable, immoveable, new, second-hand) and can be invoked against either a professional seller or a private individual.

• What it covers: The defect must be hidden (not visible at the time of purchase), exist prior to the sale, and be serious enough to make the product unfit for its intended use, or diminish this use so much that you would not have bought it (or would have paid a lower price).
• The burden of proof: Unlike the guarantee of conformity, it is up to you, the buyer, to prove by any means (expert reports, quotes, technical assessments) the existence of the vice caché (hidden defect) at the time of the sale.

3. Commercial Guarantees and After-Sales Service (SAV)

Often confused with legal guarantees, the garantie commerciale (commercial guarantee or "manufacturer's warranty") is optional. It is offered free of charge or sold as an extended warranty by the manufacturer or distributor.

• The principle: It never replaces the legal guarantees of conformity and hidden defects. It is supplementary. Its conditions (duration, geographical coverage, free parts or labor) are freely set by the warranty contract.

Repair, Replacement, or Refund: How to Choose?

The Code de la consommation strictly regulates the order of remedies applicable in the event of a lack of conformity (Article L. 217-8). You cannot immediately demand a refund if another solution is possible and reasonable.

Step 1: Choosing Between Repair and Replacement

In principle, you have the choice between having the product repaired or replaced. However, the seller can refuse your choice if:

1. The requested solution is physically impossible (for example, replacing a unique model or one that is permanently out of stock).

2. The chosen solution generates a manifestly disproportionate cost compared to the other option, taking into account the value of the good and the significance of the defect.

If the seller refuses your choice for one of these reasons, they must proceed with the other option, unless it is absolutely impossible.

Step 2: Refund (Rescission of the Sale) or Price Reduction

You can only request a full refund (by returning the product) or a partial refund (by keeping the degraded product) in very specific cases defined by Article *L. 217-14 of the Code de la consommation***:

• If the seller refuses to repair or replace the product.
• If the repair or replacement could not be carried out within 30 days following your complaint.
• If the repair or replacement causes you major inconvenience.
• If the defect persists despite the seller's attempt to bring the product into conformity.
• If the defect is so serious that it justifies an immediate price reduction or the rescission of the contract (skipping the repair/replacement step entirely).

Please note: If the lack of conformity is minor, you do not have the right to rescind the sale (full refund), but only to a reduction in price.

Deadlines, Amounts, and Key Figures to Remember

To act effectively, you must strictly respect the legal deadlines prescribed by French law:

• 2 years (24 months): This is the limitation period to take action under the legal guarantee of conformity, starting from the delivery of the goods (Article *L. 217-3 of the Code de la consommation***).
• 2 years (24 months): This is also the period to take action under the guarantee against hidden defects, but the starting point is the discovery of the defect (and not the purchase date), up to a limit of 5 years after the purchase (Article *1648 of the Code civil***).
• 30 days: This is the maximum legal timeframe the seller has to repair or replace your product after your request, at no cost to you.
• 6 months: This is the automatic extension of the legal guarantee of conformity if the product is repaired under this guarantee (Article L. 217-13). If you request a repair and the seller prefers to replace the product, the guarantee of conformity is renewed for 2 years on the new product.
• 0 €: The application of the legal guarantee of conformity must be carried out at no cost to the consumer. This includes return shipping, transport, labor, and replacement parts.

Concrete Examples of Dispute Resolution

Example 1: The Broken Television (Guarantee of Conformity)

Lucas buys a new OLED television for 1,200 € on January 10, 2023. On October 15, 2024 (i.e., 21 months after purchase), the screen displays permanent colored vertical lines.

• Applicable law: The defect appears less than 2 years after purchase. The legal guarantee of conformity applies automatically. The defect is presumed to have existed at delivery.
• The process: Lucas contacts the seller and requests a replacement television of the same model. The seller replies that this model is no longer manufactured and offers to repair the screen. Lucas accepts.
• The outcome: The repair takes 15 days. Lucas pays nothing (transport and repair costs are covered by the seller). Furthermore, the guarantee of conformity on his television is extended by an additional 6 months, protecting him beyond the original expiration date.

Example 2: The Second-Hand Car with an Engine Failure (Hidden Defects)

Sarah buys a second-hand car from a private individual for 8,500 €. Three months after the purchase, while driving on the highway, the engine suddenly seizes. An independent automotive expert report proves that a major lubrication defect, caused by an internal crack in the engine block prior to the sale, caused the breakdown. This defect was undetectable during a standard test drive.

• Applicable law: Since the transaction took place between private individuals, the guarantee of conformity does not apply. Sarah must invoke the guarantee against hidden defects (Article *1641 of the Code civil). She has 2 years* from the breakdown (discovery of the defect) to take action.
• The process: Armed with the expert report, Sarah sends a formal demand letter via registered mail to the seller. She requests the rescission of the sale.
• The outcome: Faced with undeniable physical evidence, the seller agrees to an amicable settlement: they take back the defective vehicle and fully refund the 8,500 € to Sarah.

Step-by-Step Practical Procedures

If you notice a defect in a product, follow this procedure carefully to maximize your chances of obtaining a quick resolution.

1. Gather proof of purchase: Locate the invoice, receipt, delivery slip, or failing that, a bank statement proving the transaction and its date.

2. Contact the seller's customer service: Prefer written contact first (email, contact form on the website) or note down the exact date, time, and name of the representative if you call. Describe the problem and clearly state your choice (repair or replacement) based on the legal guarantee of conformity.

3. Send a formal demand letter: If the seller refuses to apply the guarantee, ignores your request, or exceeds the 30-day limit, send a formal demand letter (mise en demeure) via Lettre Recommandée avec Accusé de Réception (LRAR - Registered Mail with Acknowledgment of Receipt). Cite Articles *L. 217-3 et seq. of the Code de la consommation and demand the execution of the guarantee within 15 days*.

4. Contact a consumer mediator: If the formal demand letter remains unanswered or if the response is unsatisfactory, you can contact the médiateur de la consommation (consumer mediator) designated by the seller free of charge (their contact details must mandatorily appear in the professional's general terms of sale or website).

5. Initiate legal action: As a last resort, for disputes under 10,000 €, you can refer the matter to the Tribunal judiciaire (Judicial Court) via a simplified petition, without the obligation of hiring a lawyer.

Mistakes to Avoid

• Returning the product at your own expense without prior agreement: The Code de la consommation states that bringing the product into conformity must be done at no cost to the buyer. Always ask the seller for a prepaid return label before shipping a package.
• Attempting to repair the product yourself: If you dismantle the device or hand it over to a repairer not authorized by the seller before claiming the guarantee, the seller can legitimately refuse to cover the product, arguing that the breakdown resulted from your tampering.
• Letting legal deadlines pass: Do not believe a seller who asks you to "be patient" or who indefinitely drags out amicable discussions. Always keep an eye on the 2-year anniversary date after purchase so you do not lose your right to take legal action.
• Accepting store credit instead of a refund: If the legal conditions for a refund are met (for example, the product is irreparable and irreplaceable), the seller must return your money. They cannot force a voucher or store credit (avoir) on you unless you expressly accept it in writing.

FAQ (Frequently Asked Questions)

My product is broken but I no longer have the original packaging. Can the seller refuse the guarantee?

No. Under no circumstances can the seller condition the application of legal guarantees (conformity or hidden defects) on you presenting the original packaging. Such a clause, if it appears in the general terms of sale, is considered unfair (clause abusive) and deemed non-existent under the law.

What happens if the seller goes bankrupt or closes their shop?

In the event of the seller's liquidation, it becomes very difficult to enforce the legal guarantee of conformity against them. However, you can turn directly to the manufacturer of the product by invoking the commercial manufacturer's warranty if it is still active, or by invoking the guarantee against hidden defects, which is transferred along with the ownership of the property.

Does the guarantee of conformity apply to online purchases made on foreign platforms?

If the foreign website (for example, based in China or the United States) actively directs its business toward France (French language website, prices in euros, delivery to France), French and European law applies. In practice, enforcement can be complex. If the seller is located within the European Union, you benefit from the same 2-year guarantee of conformity and can seek assistance from the Centre Européen des Consommateurs (CEC - European Consumer Centre).

The seller is asking me to pay "diagnostic fees" to check the breakdown. Is this legal?

No, under the legal guarantee of conformity, all verification, transport, and repair operations must be free of charge for the consumer. The seller can only bill you for diagnostic fees if they demonstrate, after analysis, that the breakdown resulted from misuse on your part (which would exclude the guarantee).

Summary

• The legal guarantee of conformity protects you for 2 years after the purchase of any new product, without you having to prove the origin of the defect.
