You’ve been back to the dealership more times than you can count for the same problem – and all under the same hood ornament. As you sit in the waiting room again, a question starts to nag at you: Is it just your luck, or does this brand make a lot of lemons?
It’s a common question in need of an honest answer, which is where a lot of articles online fall short.
First, a Reality Check on the “Rankings”
Here is something most blog posts will not tell you: California does not publish an official scoreboard ranking the car brands with the most Lemon Law claims.
No state agency hands out a trophy for “Most Lemons of the Year.”
So, when you see an article confidently listing the “Top 5 Lemon Brands” with tidy percentages next to each name, be a little skeptical about where those numbers came from.
What we can rely on is independent data: a landmark study of California court filings by nonprofit consumer groups, in addition to federal safety-recall records published by the National Highway Traffic Safety Administration (NHTSA).
Line those up, and the same handful of names keep making an appearance.
One Study Worth Knowing About
The most useful independent research here is the Auto Lemon Index, a report from the CALPIRG Education Fund, the Consumers for Auto Reliability and Safety (CARS) Foundation, and Frontier Group.
Rather than just counting lawsuits, the researchers compared California court filings against how many vehicles each manufacturer registered in the state from 2018 through 2021. The comparison measures how often a brand gets sued relative to how many cars it sells — not just raw totals that naturally favor the biggest sellers.
Two numbers from that study tell most of the story:
- General Motors was the most-often sued brand, drawing a lawsuit once for every 78 new GM vehicles registered in California.
- Toyota was the least-often sued, with just one lawsuit for every 2,029 new vehicles.
Put another way, the study found GM buyers were roughly 26 times as likely to file a Lemon Law suit as Toyota buyers.
It is worth keeping perspective, though. The same research found that of the more than 7 million new vehicles registered in California over those four years, fewer than half of one percent ended up in a Lemon Law lawsuit. Most cars really are fine. Beyond the two endpoints, secondary analyses of the same court-filing data have ranked other frequently sued brands — including Jaguar Land Rover, Stellantis (Fiat Chrysler), Nissan, and Ford — in the tier between GM and Toyota.
A Quick Word on What the Numbers Mean
Before we name names, one important distinction.
A recall is not the same thing as a Lemon Law claim.
A recall is a manufacturer or federal action fixing a safety defect across a whole population of vehicles. A Lemon Law claim refers to one owner’s case about one vehicle that could not be fixed.
Recall data is useful because it is official and comprehensive, and it shows the scale of defects a manufacturer is wrestling with. But think of it as a symptom of underlying quality problems, not a direct headcount of lemons.
With that said, the volume of Lemon Law cases in California has exploded. According to the nonprofit newsroom CalMatters, filings jumped from roughly 15,000 in 2022 to more than 22,000 in 2023. In Los Angeles County, these cases now make up close to one in ten civil filings.
Someone is generating all those claims. A few large automakers, it turns out, account for an outsized share.
General Motors: The Name That Comes Up First
If there is a headliner here, it is GM.
The Auto Lemon Index put it at the very top: one Lemon Law lawsuit for every 78 new GM vehicles registered in California, the worst rate of any brand studied. Separately, reporting by the nonprofit newsroom CalMatters noted that consumer groups tallied roughly 9,800 GM Lemon Law suits between 2018 and 2021 — nearly one in three of all such suits filed in the state during that stretch.
One automaker, nearly a third of the cases.
GM’s footprint was large enough that the company was a primary player in the negotiations behind California’s 2024 Lemon Law overhaul.
Why so many? The study’s authors point to several factors: overall vehicle quality, how promptly and effectively a brand’s dealers handle problems, and the length of the warranty offered.
In GM’s case, high sales volume across Chevrolet, GMC, Buick, and Cadillac combines with owner reports of recurring trouble in transmissions, electrical systems, and powertrain components. High volume paired with repeat defects in core systems is a recipe for claims.
Stellantis: Chrysler, Dodge, Jeep, and Ram
Stellantis is the parent of Chrysler, Dodge, Jeep, Ram, and Fiat. In 2024, it earned an unwelcome distinction.
It topped NHTSA’s list of recalls issued that year, with roughly 72 separate recall campaigns. That was more than any other automaker.
Its biggest single campaign covered more than a million vehicles over a rearview camera display defect, and its recurring problem areas included electrical systems and airbags.
When a brand family this large racks up recalls at that pace, warranty and Lemon Law complaints tend to follow. If you own a Stellantis vehicle that just cannot be made right, our team has experience taking on these manufacturers directly.
Ford: Consistently Near the Top
Ford almost always rears its head in this conversation.
It issued somewhere in the range of 62 to 67 recall campaigns in 2024, depending on which reporting cutoff you use, putting it second only to Stellantis. Several of those recalls affected hundreds of thousands of vehicles at a time.
Ford also sells enormous numbers of vehicles. Combine big sales figures with frequent recalls, and you get a brand that shows up again and again in California warranty and Lemon Law activity.
Nissan: Watch the Transmission
Nissan rounds out the usual suspects.
Its recall counts are lower than the domestic leaders, but it has drawn stubborn, long-running complaints about its continuously variable transmissions (CVTs). Owners across several model years have reported shuddering, hesitation, and outright premature failure.
Transmission problems hit a vehicle right where it hurts: drivability and value. That makes them a classic driver of Lemon Law claims, and it helps explain why Nissan keeps turning up in California disputes.
So Why These Four?
Notice the pattern.
Every one of these automakers sells a tremendous number of vehicles in California, so even an ordinary defect rate produces a lot of affected owners. Each has struggled with repeat defects in the systems drivers care about most, which are exactly the failures that substantially impair a vehicle’s use, value, or safety. And every one spans multiple sub-brands, multiplying the models on the road.
Volume plus repeat core-system defects. That’s the combination.
One caveat worth saying out loud: landing on this list does not mean every vehicle these companies build is a lemon. The majority are perfectly fine. But if you own one of the unlucky ones, the manufacturer’s size is not a defense, and California law still has your back.
So, Who Makes the Fewest Lemons?
The quiet end of the list is just as interesting — and here Toyota is the standout.
In the Auto Lemon Index, Toyota was the least-often sued brand in California, drawing just one lawsuit for every 2,029 new vehicles registered. That is a dramatically better rate than GM’s one-in-78, and it is why the study singled Toyota out at the opposite end of the spectrum.
Federal recall data tells a similar story for a few others. In NHTSA’s 2024 recall figures, Mazda was among the very lowest, with only about half a dozen vehicle recalls on the year, and Rivian and Porsche also landed near the bottom of the recall count.
A low rate is not a promise of a perfect car, and it does not mean these brands never see a Lemon Law claim. But it does hint at tighter quality control and fewer systemic defects, which usually means fewer warranty headaches overall. If you are shopping and reliability is a priority, this kind of data is one useful input, right alongside long-term dependability studies and warranty coverage.
What If Your Car Is One of Them?
Here is the part that matters: the badge on your hood matters far less than your repair history.
Whether your vehicle wears one of the names above or a brand that almost never appears in these rankings, the California Lemon Law test is the same. If a substantial defect covered by the manufacturer’s warranty cannot be fixed after a reasonable number of repair attempts, you may be entitled to a buyback, a replacement vehicle, or cash compensation.
What wins that case is documentation, not the logo.
Why The Lemon Lawyer?
The Lemon Lawyer has taken on manufacturers of every size, from the biggest domestic automakers to import and luxury brands. Drivers choose the firm because of:
- More than 25 years of California Lemon Law experience

The Bottom Line
A few big automakers do account for an outsized share of California’s Lemon Law claims, and the official recall and court data back that up. But no brand is automatically a lemon, and no brand is automatically safe. What decides your case is whether your vehicle’s defect keeps coming back and whether you have the records to prove it.
If your vehicle keeps returning to the shop for the same unresolved problem, the brand is only the beginning of the story. Reach out to The Lemon Lawyer today for a free consultation, and find out whether your vehicle qualifies under California Lemon Law — no matter who made it.

TL;DR
California does not publish an official ranking of Lemon Law claims by brand, but independent research does. The Auto Lemon Index, from the CALPIRG Education Fund and partners, compared court filings to vehicles registered from 2018 through 2021 and found General Motors the most-often sued brand (one lawsuit per 78 vehicles) and Toyota the least (one per 2,029). Federal NHTSA data adds context: Stellantis (Chrysler, Dodge, Jeep, Ram) led all automakers in 2024 recalls, with Ford close behind, while Nissan draws persistent complaints over its CVT transmissions. Brands like Mazda, Rivian, and Porsche generate the fewest recalls. Still, fewer than half of one percent of new vehicles end up in a Lemon Law suit. What determines your claim is a recurring, unrepaired, warranty-covered defect, not the logo on the car.

FAQ
Does California rank car brands by Lemon Law claims?
No. There is no official state ranking. The best available evidence comes from court-filing data reported by nonprofit newsrooms and consumer groups, and from federal safety-recall data published by NHTSA.
Which car brand has the most Lemon Law claims in California?
General Motors. The Auto Lemon Index, an independent study by the CALPIRG Education Fund and partners, found GM was sued once for every 78 new vehicles registered in California from 2018 through 2021 — the highest rate of any brand studied.
Are recalls the same as Lemon Law claims?
No. A recall addresses a safety defect across many vehicles at once. A Lemon Law claim is an individual case about a single vehicle that could not be repaired. Recall data is a useful indicator of quality problems, not a direct count of lemons.
Which car brands have the fewest problems?
In the same Auto Lemon Index, Toyota was the least-often sued brand, at just one lawsuit per 2,029 vehicles. In NHTSA’s 2024 recall data, Mazda, Rivian, and Porsche were among the manufacturers with the fewest recall campaigns. A low rate is a good sign but not a guarantee.
My car is a common brand. Can I still have a claim?
Yes. The brand does not decide your claim. If a substantial, warranty-covered defect cannot be fixed after a reasonable number of repair attempts, you may qualify regardless of who made the vehicle.
