Understanding Car Warranties: What Still Applies When the Car Isn’t New

A warranty is not a promise of perfection. It’s a definition of responsibility. And when it comes to second-hand cars, that definition becomes narrower — but not meaningless. Most buyers misunderstand warranties. Not because they’re careless, but because the language is vague, and the rules change once ownership changes. This is what still applies. And what doesn’t.

1. What a Warranty Actually Is

A warranty is a legal obligation, not goodwill. It defines:

• Who is responsible
• For which defects
• Within which time window
• Under which conditions

It does not cover:

• Normal wear
• Consumables
• Damage caused by use or neglect

And it does not guarantee that nothing will fail. It guarantees who carries the cost if it does.

2. The New-Car Warranty: What Can Transfer

Most new cars in Switzerland come with:

• 2–5 years manufacturer warranty
• Sometimes extended coverage for drivetrain or battery (especially EVs)

This warranty can transfer to the next owner. But only if:

• The warranty period is still active
• The service schedule was respected
• No modifications voided coverage

For second-hand buyers, this is the best-case scenario. A used car with remaining manufacturer warranty is not “almost new.” It is still contractually protected.

3. Factory Warranty vs. Dealer Warranty

These are not the same.

Manufacturer Warranty

• Issued by the car brand
• Valid across authorized workshops
• Terms are standardized
• Often transferable

Coverage is usually comprehensive, but strict.

Dealer Warranty

• Issued by the selling dealer
• Coverage depends on the contract
• Often limited in scope and duration

Dealer warranties vary widely:

• Some cover major components only
• Some exclude electronics
• Some require repairs at specific garages

They are not automatically bad — but they are not interchangeable with factory coverage. Read them.

4. Used Cars Without Warranty: What the Law Says

In Switzerland, private sales often exclude warranties entirely. This is legal. The key phrase is: “Garantie wegbedungen” — warranty excluded. Once this is in writing:

• The buyer assumes most risks
• The seller is only liable for concealed defects knowingly hidden

That threshold is high. And difficult to prove. Dealer sales are different. Professional sellers cannot fully exclude liability in the same way — even if warranties are limited. This is why dealer-bought used cars often cost more. You’re not paying for optimism. You’re paying for accountability.

5. The Time Window That Matters

For used cars, warranty relevance follows a simple rule: The older the car, the narrower the coverage. Typical scenarios:

• 0–12 months old → often remaining factory warranty
• 12–36 months → partial manufacturer or dealer warranty
• 3+ years → usually dealer warranty or none

Extended warranties can bridge the gap — but they are insurance products, not guarantees. They have:

• Deductibles
• Caps
• Exclusions

They reduce risk. They don’t remove it.

6. What Is Commonly Covered — and What Isn’t

Often Covered

• Engine (major internal failures)
• Transmission
• Differential
• High-voltage battery (EVs, with conditions)

Often Excluded

• Wear parts (brakes, clutch, tires)
• Software issues
• Interior components
• Cosmetic defects

The closer a defect is to “usage,” the less likely it is to be covered.

7. Why Warranties Matter More for Used Cars

With a new car, a warranty is background noise. With a used car, it’s a risk buffer. It:

• Protects against unknown history
• Reduces repair cost uncertainty
• Influences resale value

A used car without warranty is not a mistake. But it requires:

• Better inspection
• Stronger documentation
• More realistic pricing

Warranty doesn’t replace due diligence. It complements it.

8. The Question Buyers Should Actually Ask

Not: “Does this car have a warranty?” But: “Who pays if this breaks next?” If the answer is clear — and documented — the risk is manageable. If it isn’t, no warranty badge will save you.

9. The 2026 Pivot: Time Is on Your Side

For decades, the Swiss system favored the silent seller. If you didn’t shout about a defect within days, you were at the mercy of the market. That changed on January 1st.

The 60-Day Rule:

You no longer have to race to a mechanic the morning after a purchase. The 2026 revision of the Code of Obligations gives you 60 days to report a defect from the moment you find it. The law now recognizes that complexity takes time to reveal itself.

The Right to a Cure:

If a professional dealer sells you a car with a fundamental flaw, their first move can no longer be a shrug. The 2026 standard prioritizes Repair. You are not just buying a car; you are buying the legal right to have that car meet its promised standard.

Battery Integrity:

In the era of the used EV, “capacity” is the new “mileage.” If the battery’s health is significantly lower than represented, it isn’t just a disappointment—it’s a legal breach. In 2026, transparency isn’t a courtesy. It’s the law.

The Takeaway

Warranties don’t make cars safe. They make responsibility visible. For second-hand cars:

• Remaining manufacturer warranty is gold
• Dealer warranties vary — read them
• Private sales shift risk to the buyer

There is no universal protection. Only informed positioning. And in the used car market, clarity is worth more than coverage.
