The history of warranties: How “buyer beware” gave way to today’s consumer protection laws

A couple in a Montreal appliance store were circling a washing machine, the way people do when they’re about to spend more than they’d planned. The guy leans in toward the price tag, then frowns at a second number printed right beside it.

He looks toward the salesman, hoping he’ll understand the question from one look, and he does.

The salesman taps the second number on the tag. “It’s how many years that machine has to keep working.”

“Has to?”

“Yes, by law,” the salesman answers.

The number is there because Quebec now requires it. Since October 5, 2026, a new warranty of good working order has covered goods such as appliances and electronics for minimum periods ranging from 3 to 6 years. So if one stops working within that window, the merchant or manufacturer has to cover the repair, including parts and labor.

Protection like that didn’t appear overnight, though. It’s the latest chapter in a story that has been unfolding for centuries, even if most of us have never heard it.

The idea goes back at least to medieval markets, where selling bad goods could land a trader in serious trouble (death penalty wasn’t that bothersome back then), and putting things right was seen as his duty, even when he hadn’t known about the flaw. From there, judges and eventually governments pushed and pulled the warranty for centuries, until it shrank into the dense little booklet most of us never read.

So let's head back to that market stall and trace how one simple promise grew into the warranty we know today.

When a cracked pot was the seller’s problem

In 1364, at Walter Doget’s tavern in St Leonard’s Eastcheap, a taverner named John Penrose was caught selling red wine that had long since turned. The four officials who supervised the City’s wine sales found him guilty of selling wine that was unsound and unwholesome, in deceit of the common people.

The court’s sentence read:

“John Penrose shall drink a draught of the same wine which he sold to the common people; and the remainder of such wine shall then be poured on the head of John Penrose; and he shall forswear the calling of a vintner in the City of London for ever.”

None of that put a single coin back in his customers’ pockets. It was a punishment, not a refund. But it showed just how seriously medieval London took a bad sale.

Twenty-odd years earlier, the city’s vintners had already agreed that no taverner should mix putrid wine with good. Drinkers could even march into the cellar and watch their wine being drawn from the barrel. Call it quality control, medieval style.

The church went a step further. Since at least medieval times, it held sellers of substandard goods responsible for putting the wrong right, even when they hadn’t known about the defect. That duty later found its way into feudal institutions and the law merchant.

For a while, the risk of a bad buy sat squarely with the seller. Then trade changed, and so did the rules.

How “buyer beware” took over the market

As feudal life faded and a new merchant class took charge of trade, the seller’s duty to put a bad sale right began to slip away. In its place came a rule with a blunt Latin name, caveat emptor, or “let the buyer beware.”

And with that, a bad purchase became the buyer’s problem. To get any compensation from an English court, a buyer had to prove the seller knew about the defect, or show that he’d backed his promise with the ‘magic word warranty.’”

One of the era’s best-known cases involved a man named Lopus. In 1603, he paid a goldsmith named Chandelor £100 for a bezoar stone, prized at the time for its healing powers. When it turned out to have none, Lopus took Chandelor to court, and eventually lost.

The court ruled that Chandelor may have called it a bezoar, but he never expressly warranted it, and that was enough to let him off. In other words, a seller’s word was only as good as the vocabulary he chose. That really would have been the stuff of dreams for most sellers today.

Rulings like that didn’t sit comfortably for long. A common critique of caveat emptor was that it served those with the most knowledge and power, usually the seller. And the courts grew firm that knowingly misdescribing what you sold should give the buyer a claim.

By mid-18th century, warranties changed too. Instead of being treated as a question of fraud, they slowly became part of the deal itself. In 1778, an English court confirmed that a buyer could sue over a broken express warranty, and that this had been the case for some time.

For everyday shoppers, though, the burden still sat firmly on their side of the counter.

The law starts siding with buyers again

English common law had long since sailed across the Atlantic, with “buyer beware” tucked in its luggage. The rule loosened its grip slowly, and one of its biggest cracks came from a single pebble hitting a Ford windshield.

In Washington State, a man named Baxter bought a Ford Model A Town Sedan after both the dealer and Ford’s own sales catalog assured him its windshield was made of shatterproof glass. A few months later, a pebble kicked up by a passing car hit it. The glass shattered, and Baxter lost his left eye.

But under a doctrine called privity, only the parties to a contract could sue over it, and Baxter had bought his car from the dealer, not from Ford.

In 1932, the court let him go after Ford anyway. That move didn’t rewrite the rules overnight, but it was a pivotal moment showing where things were heading. Back in Britain, the law had already started down that road.

In 1893, its Sale of Goods Act made every sale come with basic promises built in, like the goods matching what was described and doing the job they were sold for. A seller didn’t have to say these things out loud. The law said them for him.

In the US, the Uniform Commercial Code, first published in 1952 and adopted by the states over the years that followed, gave buyers two kinds of protection: the promises a seller made out loud, and the ones the law assumed whether he said them or not. Then, in 1975, Congress took aim at the fine print itself. Under the Magnuson-Moss Warranty Act, a company didn’t have to offer a warranty at all. But if it did, it had to say plainly whether it was “full” or “limited,” so shoppers knew what they were getting before they paid.

North of the border, Canada’s provinces went their own way. New Brunswick’s 1978 consumer warranty law even took the old Latin motto and flipped it: fidem habeat emptor, “let the buyer have confidence.”

After nearly four centuries, the buyer finally had the law moving in their corner.

From fine print to front page

While lawmakers were busy writing warranties into the rulebook, a few clever salesmen spotted a gap everyone had missed. Besides protecting the buyer, a warranty could also sell the product.

Fountain pens were among the first to cash in. In 1920, Walter Sheaffer launched a pen with a lifetime warranty and slapped an $8.75 price tag on it, nearly three times what most pens cost. From 1924, his ads told buyers to look for a tiny white dot on the cap, the badge of a pen “unconditionally guaranteed for a lifetime.”

Cars were late to the party despite being faster than pens. Although Maxwell did provide a 90-day cover, it left out the tires, rims, magnetos, coils, batteries, and lamps, a list that covered a good chunk of the car. Then, in 1963, Chrysler rolled out five years or 50,000 miles of cover on its engines and transmissions.

Most rivals first snickered, then scrambled to match it. Chrysler, meanwhile, leaned into its new advantage, putting the warranty ahead of the cars’ own features in its ads, with a jingle promising “five long years or 50,000 miles.”

Even the living room got in on the act. Curtis Mathes, a Texas TV maker, built sets with snap-in parts so a repair call took minutes, then backed them with four years of cover on the picture tube, parts and labor. Its ads cheerfully billed it as the most expensive TV in America, and darn well worth it.

Each industry found its own way to sell the warranty, yet every one of them left buyers holding the same two loose threads, an end date and a list of exclusions. It was only a matter of time before someone offered to tie them up.

The extended warranty steps in

Chrysler, which had sent rivals scrambling with five years of cover, cut its warranty on 1969 cars to just one year. Other makers trimmed theirs through the 1970s.

Into that gap stepped the extended warranty. Car service contracts had existed in some form since the late 1950s, but the 1970s is when they really took off, offering cover that picked up where the factory warranty left off.

By 1980, the idea had reached every living room. A company called VAC Service Corp. started out that year selling extended warranties on VCRs, the must-have gadget of the decade. Retailers soon followed, and Sears offered its own “maintenance agreements,” covering repairs from wear and tear and adding a yearly check-up.

As the market grew, so did the rules that kept it fair. Many US states began regulating these plans as service contracts, often through their insurance commissioners.

One habit has stuck, though. Many plans still have to be bought at checkout or within a very short window after it. Some, like SureBright Anywhere, stretch that window to 90 days.  Coverage is available on almost all purchases, no matter where you have bought them from.

Conclusion

Back in that Montreal store, the couple wheels their new washing machine toward the till. They may not know it, but they’re carrying nearly seven centuries of arguments with them, from a taverner drenched in his own wine to a pebble that cracked Ford’s defense wide open.

Their washer comes with a limited number of years of protection written into law. But like every warranty, from the most basic to the most generous, it eventually reaches its end date.

That’s the gap SureBright Anywhere is built for. Once the manufacturer’s coverage ends, its extended warranty covers mechanical and electrical breakdowns, including the ones caused by normal wear and tear, and eligible plans protect against power surges from the day you buy. If something covered breaks down, SureBright arranges the repair, or a replacement or reimbursement if it can’t be fixed.

The law is finally in your corner, so add one more ally with SureBright Anywhere.
