Why Do People Call Old Cars “Lemons”?

They’re called “lemons” because, starting in early 20th‑century American slang, a “lemon” came to mean a dud or disappointing purchase—something that looks fine at first but turns out sour. As mass car ownership grew, the term attached itself to vehicles with chronic defects, and later to consumer-protection “lemon laws.” While people often say “old cars,” the label applies to any persistently faulty vehicle—new or used.

From sour fruit to sour deals: the slang “lemon”

The lemon’s literal sourness made it a natural metaphor for an unpleasant experience or a deal that leaves a bad taste. By the early 1900s in U.S. slang, to “hand someone a lemon” meant to stick them with something worthless or disappointing, and “a lemon” became a byword for a dud.

What about slot machines and British slang?

Some etymologies point to early slot machines that used fruit icons, including lemons, where lemon combinations could yield little or nothing—reinforcing a “bad draw” association. Others note British and American slang that used “lemon” for a fool or a flop. While these threads likely reinforced the meaning, lexicographers generally trace the product-related “dud” sense to early 20th‑century U.S. usage tied to disappointing purchases.

How cars entered the picture

As automobiles became mainstream in the 1910s–1930s and the used‑car market expanded after World War II, consumers and newspapers increasingly used “lemon” for cars with recurring, hard‑to-fix problems. The term stuck because vehicles are complex, expensive, and, when defective, especially frustrating—perfectly fitting the “looks good, turns out sour” metaphor.

Not just “old” cars

Although people often say “old cars,” “lemon” doesn’t mean “aged.” It refers to a vehicle—new or used—with substantial, repeated defects. A brand‑new car that spends weeks in the shop can be a lemon; a well‑maintained 20‑year‑old car that’s reliable is not.

From slang to statutes: the rise of “lemon laws”

The consumer‑protection meaning became formalized with legislation. The federal Magnuson‑Moss Warranty Act (1975) strengthened warranty enforcement, and in 1982, Connecticut enacted the first state “lemon law” specifically for new cars. Today, all U.S. states and D.C. have new‑car lemon laws, and several have specific protections for used cars (for example, New York, New Jersey, and Massachusetts), though coverage and remedies vary.

Here are typical features found in many state lemon laws, which help show how the term is used in practice.

• Covered defects: A problem that substantially impairs the vehicle’s use, value, or safety.
• Time/mileage window: Usually within the first 12–24 months or 12,000–24,000 miles (varies by state).
• Reasonable repair attempts: Often 3–4 attempts for the same defect, or one attempt for a serious safety defect.
• Days out of service: Commonly around 30 cumulative days in the shop within the coverage period.
• Remedies: Replacement vehicle or a refund (minus reasonable use), plus possible attorney’s fees.
• Used‑car coverage: Some states provide limited used‑car lemon protections or mandatory dealer warranties; others rely on general warranty and fraud laws.

The specifics depend on the jurisdiction, but the consistent thread is that a “lemon” is a vehicle with repeated, substantial defects the manufacturer or seller can’t fix within a reasonable time.

The economics of “lemons”

The term also gained academic prominence with economist George Akerlof’s 1970 paper, “The Market for ‘Lemons’: Quality Uncertainty and the Market Mechanism.” He used “lemons” to describe low‑quality used cars that sellers know more about than buyers—a classic information‑asymmetry problem. The idea helped explain why bad products can drive out good ones in poorly signaled markets and later contributed to Akerlof’s 2001 Nobel Prize in Economics (shared with Michael Spence and Joseph Stiglitz).

Common confusions and nuances

Because “lemon” has entered everyday language, people sometimes blend it with other car slang. These points clarify what it does—and doesn’t—mean.

• Lemon vs. clunker: A “lemon” has persistent defects; a “clunker” is just old, worn, or low‑value but not necessarily defective.
• New vs. used: New cars can be lemons. Used cars can be lemons. Age alone doesn’t determine the label.
• One bad repair doesn’t make a lemon: The idea is repeated, substantial problems, not a single fixable issue.
• Law vs. colloquial use: Calling a car a “lemon” informally doesn’t guarantee it meets your state’s legal definition for a buyback or refund.

In short, “lemon” is about chronic, material defects—not merely age, mileage, or price—and legal remedies hinge on precise statutory criteria.

How the term is used today

Modern usage spans casual conversation, journalism, law, and economics. Auto buyers say they “got sold a lemon” when repairs never end; attorneys bring “lemon law” claims for buybacks; economists still invoke the “lemons” framework to discuss information problems in many markets, from cars to consumer electronics.

Summary

People call old cars “lemons” because “lemon” became early 20th‑century slang for a disappointing, defective purchase—a metaphor that fit problematic cars perfectly. The term moved from street talk to statutes via U.S. lemon laws, and from headlines to textbooks via Akerlof’s “lemons” model. Crucially, “lemon” doesn’t mean “old”; it means chronically faulty. That’s why both brand‑new and aging vehicles can be lemons, while many old cars are not.

Why do we call cars lemons?

A “lemon car” is called that because the term “lemon” has been used as slang for a disappointing or worthless product since the early 20th century, particularly in British and American English. The word originally referred to something of poor quality that fails to meet expectations, like a sour citrus fruit. The term was specifically applied to defective cars, often those that seem fine at first but develop major, unsolvable mechanical issues over time.
 
Origin of the “Lemon” Slang

• Early 20th Century Slang: The term “lemon” became slang for a disappointing or low-quality item around the turn of the 20th century in both the UK and America. 
• British Origins: One theory suggests the term came from British slang, where “to hand someone a lemon” meant to pass off a substandard article as something good. 
• American Adoption: Americans adopted this slang in the early 1900s to describe junk products. 

Application to Vehicles

• Disappointing Vehicles: The term was later applied to the automotive industry to describe cars that failed to meet quality and reliability standards. 
• Hidden Defects: A “lemon” car is often one that looks normal from the outside but has significant, hidden mechanical defects that become apparent after purchase. 
• Sour Experience: Just as a bad lemon leaves a sour taste, a defective car leaves the owner with a “sour feeling” due to the disappointment and frustration of dealing with problems, notes www.texaslemonlawblog.com.
