What Are Lemon Laws and How Do They Work?

According to the Federal Trade Commission (FTC), new and used car buyers in the United States file thousands of warranty-related complaints each year. The FTC enforces the Magnuson-Moss Warranty Act (15 U.S.C. § 2301 et seq.), a federal law that protects consumers when manufacturers fail to honor written warranties.

Alongside federal protection, every U.S. state has its own lemon law to protect buyers from defective vehicles. Buying a car that breaks down repeatedly within weeks feels frustrating, expensive, and unfair. Lemon laws exist to protect consumers in exactly that situation.

What Are Lemon Laws?

Lemon laws are consumer protection laws that require manufacturers to repair, replace, or refund defective vehicles that cannot be fixed after a reasonable number of repair attempts.

In simple words, lemon laws protect buyers from defective new cars — and in some states, defective used cars — when the manufacturer fails to fix serious problems under warranty.

A vehicle becomes a “lemon” when:

• The defect substantially impairs use, safety, or value
• The defect occurs within a specific time or mileage limit
• The manufacturer cannot fix the problem after multiple repair attempts

Each U.S. state has its own lemon law statute. Federal law provides additional protection.

The Federal Lemon Law: Magnuson-Moss Warranty Act

The Magnuson-Moss Warranty Act, passed in 1975, protects consumers nationwide.

This federal law applies to products costing more than $10 that come with written warranties, including motor vehicles.

Under the Magnuson-Moss Warranty Act:

• Manufacturers must honor written warranties
• Consumers can sue for breach of warranty
• Consumers can recover attorney fees if they win

This law does not replace state lemon laws. It strengthens consumer rights.

State Lemon Laws: Why They Matter?

All 50 states and Washington, D.C. have lemon laws, but details differ.

You must check your specific state requirements because deadlines and repair attempt numbers vary.

What Qualifies as a Lemon in the USA?

A vehicle qualifies as a lemon when it meets 4 main conditions:

1. The Vehicle Has a Substantial Defect

The defect must affect:

• Safety (brake failure, steering problems)
• Use (engine stalls repeatedly)
• Value (major transmission failure)

Minor cosmetic issues like paint scratches usually do not qualify.

2. The Defect Occurs During the Warranty Period

Most state lemon laws apply within:

• 12 to 24 months
• Or 12,000 to 24,000 miles

Whichever comes first.

3. Reasonable Repair Attempts Were Made

Most states define “reasonable” as:

• 3 to 4 repair attempts for the same issue
• OR 1 repair attempt for a serious safety defect
• OR 30 cumulative days in the repair shop

For example:
Your car stays in the dealership repair shop for 35 total days within the first year. That meets the 30-day rule in many states.

4. Manufacturer Failed to Fix the Problem

The defect must still exist after repair attempts.

How Lemon Laws Work: Step-by-Step Process?

Here’s exactly how lemon laws work in the United States.

Step 1: Report the Problem Immediately

Document the defect as soon as it appears. Visit an authorized dealership for repair.

Step 2: Keep Written Records

Save:

• Repair invoices
• Work orders
• Warranty documents
• Communication emails

Without written proof, your claim becomes weak.

Step 3: Allow Required Repair Attempts

Follow your state’s repair attempt rule. Do not delay service.

Step 4: Send Formal Notice

Some states require written notice to the manufacturer before filing a claim.

Step 5: File a Lemon Law Claim

Options include:

• State arbitration program
• Manufacturer arbitration program
• Civil lawsuit

Step 6: Resolution

If successful, you receive:

• Refund (buyback)
• Replacement vehicle

Refund vs Replacement: What Do You Get?

Most state lemon laws offer two remedies.

1. Refund (Buyback)

Manufacturers must repay:

• Purchase price
• Taxes
• Registration fees
• Finance charges
• Incidental expenses

Minus a mileage usage deduction.

Example Calculation

Car price: $40,000
Miles before first defect: 5,000
State mileage divisor: 120,000

Usage deduction = (5,000 ÷ 120,000) × $40,000
= $1,666

Refund = $38,334

2. Replacement Vehicle

Manufacturer provides a comparable new vehicle at no extra cost.

Do Used Cars Qualify Under Lemon Laws?

Used vehicles qualify in some states.

States like:

• California
• New York
• New Jersey

Provide limited used car lemon law protection.

However, federal Magnuson-Moss Warranty Act applies to used cars that still have a manufacturer’s warranty.

Vehicles Covered Under Lemon Laws

Covered vehicles often include:

• Passenger cars
• SUVs
• Pickup trucks
• Vans

Some states include:

• Motorhomes
• Motorcycles
• Electric vehicles

Commercial vehicles over certain weight limits often do not qualify.

Time Limits to File a Lemon Law Claim

Time limits vary by state.

Common limits include:

• 18 to 24 months from purchase
• 12,000 to 24,000 miles
• 4-year statute of limitations for lawsuits

You lose protection if you miss deadlines.

Arbitration vs Lawsuit

Many manufacturers require arbitration before court.

Arbitration is:

• Faster
• Less formal
• Usually free

However, arbitration decisions may limit further legal options.

A lawsuit allows:

• Jury trial
• Attorney representation
• Potentially larger compensation

Common Mistakes That Ruin Lemon Law Claims

Avoid these 7 mistakes:

1. Waiting too long to report defects
2. Using unauthorized repair shops
3. Losing repair paperwork
4. Modifying the vehicle
5. Ignoring manufacturer recall notices
6. Failing to send written notice
7. Exceeding mileage/time limits

What Defects Qualify Under Lemon Law?

Qualifying defects include:

• Engine stalling
• Transmission slipping
• Brake failure
• Steering malfunction
• Electrical system failure
• Battery defects in electric vehicles

Non-qualifying issues:

• Wear and tear
• Cosmetic defects
• Owner-caused damage

Electric Vehicles and Lemon Laws

Electric vehicle lemon law claims increased significantly between 2020 and 2025.

Common EV defects include:

• Battery range loss
• Charging system failure
• Software malfunctions

Most state lemon laws apply to EVs the same way as gasoline vehicles.

How Long Does a Lemon Law Case Take?

Typical timelines:

• Arbitration: 30 to 60 days
• Settlement negotiation: 60 to 90 days
• Court case: 6 to 18 months

Many cases settle before trial.

Do You Need a Lemon Law Attorney?

Most lemon law attorneys work on contingency.

You pay $0 upfront.
Manufacturer pays attorney fees if you win.

Hiring an attorney increases success rates significantly, especially in complex cases.

Final Thoughts

Lemon laws protect consumers from defective vehicles that manufacturers fail to repair. Federal law through the Magnuson-Moss Warranty Act strengthens those protections. State lemon laws provide detailed procedures, deadlines, and compensation formulas.

You deserve a safe, reliable vehicle. Document every repair, act quickly, and understand your state’s lemon law rules before time runs out. A defective vehicle costs money, time, and safety. Lemon laws exist to restore fairness in the marketplace.
