Ontario Lemon Law Attorney

Help for drivers in Ontario and the western Inland Empire, including Rancho Cucamonga, Upland, and Montclair, whose new, leased, or used vehicle keeps failing under warranty.

Lemon Law Rights in Ontario at a Glance

Bought or leased in Ontario and watching the same warranty fault come back again and again? California's Song-Beverly Act gives you leverage. The manufacturer can be made to take the vehicle back, hand over a replacement, or settle for cash. Reviewing the file is free, and a winning claim shifts the legal fees onto the maker instead of you.

Who Qualifies

A warranty-covered defect that substantially impairs the vehicle's use, value, or safety and that the manufacturer cannot fix in a reasonable number of tries.

Repair Thresholds

Roughly four attempts for the same defect, two for a serious safety problem, or the car out of service 30 or more cumulative days.

What You Can Recover

A buyback (refund minus a mileage offset), a replacement vehicle, or a cash settlement that lets you keep the car.

Cost to You

Nothing out of pocket. Under the Song-Beverly Act the manufacturer covers your attorney fees when you win.

Good to Know

The rules tightened after the October 2024 Rodriguez v. FCA decision. A used vehicle sold with only the balance of a factory warranty generally no longer qualifies for a buyback or replacement, though a certified pre-owned car with its own new warranty may still qualify, and owners can often still recover damages and fees.

How the Lemon Law Plays Out in Ontario

What a warranty claim looks like for an Ontario driver, and how California's law reads in a freight and airport town.

Ontario sits at the western gateway of the Inland Empire, where the 10, the 15, and the 60 feed into one of the busiest logistics corridors in the country. The city is built around movement: Ontario International Airport, the rail yards, and the warehouses that ring the area keep a constant flow of vans, trucks, and commuters on the road. People who live in Ontario often drive west into Los Angeles County for work or run delivery and trade routes across the IE all day, which means the cars and work vehicles here log serious miles under hard, stop-and-go conditions. When a new vehicle develops a warranty defect in that environment, the problem rarely stays hidden for long. California's Song-Beverly Consumer Warranty Act steps in here. If a covered defect on a new or certified pre-owned vehicle eats into its safety, its day-to-day use, or its resale value, and the dealer burns through a fair number of attempts without fixing it, the law makes the manufacturer eat the cost rather than the driver.

Ontario is also one of the largest car-buying markets in the region. The Ontario Auto Center and the dealerships clustered along the freeways draw shoppers from across the western Inland Empire, which is part of why so many warranty claims here involve cars bought close to home. That density cuts both ways: it is convenient when you buy, but it also means a lot of drivers are stuck shuttling a defective vehicle back and forth to the same service department that cannot seem to fix it. Add the Inland Empire heat, which strains cooling systems, transmissions, and EV battery packs through the summer, and a small defect can turn into a recurring one fast. We know how to document a problem a dealer keeps marking as "operating as designed."

Local geography shapes the file. Most Ontario warranty claims trace back through the Ontario Auto Center and the dealerships toward Rancho Cucamonga, Upland, and Montclair. Because Ontario sits in San Bernardino County, a claim that cannot be settled through negotiation generally proceeds in San Bernardino County Superior Court, usually because that is where the car was bought or where the owner lives. Knowing where these cases actually move keeps the communication fast and the strategy grounded in how things work on the ground in this part of the IE.

How We Work an Ontario Claim

Drivers tend to find us once the same problem has gone in two or three times and the car still acts up. The work then breaks into four steps:

Under Song-Beverly, the manufacturer pays your attorney fees on a successful claim, so getting help costs you nothing out of pocket. Firm attorneys Michael Saeedian (California Bar No. 265470) and Arash Khorsandi (California Bar No. 249405) lead these cases. Past results do not guarantee a similar outcome.

Which Vehicles Qualify in Ontario

When a defect keeps dragging the vehicle back to the same shop, a claim is usually hiding in there. Here is what coverage takes in.

What the claim needs is a genuine warranty defect the manufacturer keeps failing to resolve after a fair number of attempts. Past that, the statute casts wide: new and used cars, pickups, SUVs, motorcycles, and leased vehicles all count, and so do many vehicles used for the job, not just the family. Since Ontario lives on freight and last-mile delivery, the failures that come across the desk lean toward drivetrains, brakes, and cooling worn down by hard daily duty, plus blown engines, transmissions that slip or jolt, electrical and infotainment glitches that flicker in and out, and EV battery or charging trouble. A dent or paint flaw or anything from a collision sits outside the law.

Are Used Cars Covered in Ontario?

Sometimes, though October 2024 changed the calculus. The Rodriguez v. FCA decision means a used vehicle carrying only the leftover stretch of the original factory warranty generally cannot reach a buyback or a replacement anymore. A certified pre-owned vehicle that came with its own new warranty is the live exception, and in Ontario that comes up constantly, given how much CPO stock cycles through the Auto Center and the surrounding lots. Losing the buyback is not the same as losing the case; damages and attorney fees may survive. So save every repair order, go through the warranty line by line, and get a read before you assume the door is shut.

New Car vs. Used Car Claims

Song-Beverly covers a new car top to bottom. Let a covered defect compromise safety, usability, or value with no fix in sight, and the ground for a buyback, replacement, or settlement is firm, and the file usually moves quickly. The used-car picture shifted with Rodriguez v. FCA in October 2024. With nothing left but the remainder of a factory warranty, a buyback or replacement is usually off the menu; carrying its own certified pre-owned warranty, the car may still qualify, and damages and fees can stay reachable in either case. Your situation gets read and pointed in the right direction before you sign on.

What an Ontario Claim Can Recover

Cases tend to end one of three ways: the maker buys it back, replaces it, or pays you to keep it.

In a buyback, the manufacturer buys the car back and pays you back: your down payment, the monthly payments, tax and registration, and side costs like a tow or a rental, trimmed only by an offset for the miles before the defect appeared. A replacement puts a comparable new vehicle in your hands at no extra charge. A cash settlement leaves the keys with you and compensates for the lost value and the money you sank into repairs. None of it is one-size, so we talk through which fits before a choice is locked in.

How long it runs depends on the file. Ontario cases generally close anywhere from a couple of months to about a year. Clean repair records move fast; a trip up to San Bernardino County Superior Court drags it out. At each step, the call on any offer stays yours.

Ontario Lemon Law Questions

Answers to the questions Ontario and Inland Empire drivers ask us most.

It can. California's lemon law reaches leased vehicles and many vehicles used for business, including the delivery vans, sprinters, and pickups that the logistics economy around Ontario and the airport runs on. The defect still has to be substantial and warranty-covered, and the same repair thresholds apply. If a work vehicle keeps coming back to the shop for the same failure, bring us the lease or purchase paperwork and the service records, and we can tell you whether it qualifies.
It does not bar a claim. California ties most defects to the warranty window and to how many times the dealer failed to fix the problem, not to how your miles were driven. Heavy stop-and-go use can actually expose certain defects sooner, such as transmissions that shudder at low speed or brakes that wear unevenly. What matters is the repair record: if the dealer logged the same problem several times and never resolved it, that pattern is what supports your case.
Yes. California counts the days a vehicle is out of service for warranty repairs cumulatively, and that includes time spent waiting on a back-ordered part. Thirty or more total days out of service for covered repairs can support a claim on its own, separate from the count of repair attempts. Keep your loaner agreements and every service ticket from the area dealerships; those dates are often the cleanest evidence in the file.
Most claims settle through negotiation and never reach a courtroom. If yours does require a lawsuit, Ontario sits in San Bernardino County, so venue commonly lands in San Bernardino County Superior Court, generally because that is where the vehicle was bought or where you live. Either way, the manufacturer pays the litigation costs on a successful claim, and we handle the filings and appearances. You are not expected to manage the court process on your own.
It can, and the certified pre-owned distinction is the key. After the October 2024 Rodriguez v. FCA decision, a used vehicle sold with only the leftover balance of the original manufacturer's warranty generally no longer qualifies for a buyback or replacement. But a certified pre-owned car sold with its own new warranty can still qualify, and CPO inventory moves heavily through Ontario's large auto market. Even when a buyback is off the table, many used-car owners can still pursue damages and attorney fees, so bring us the warranty paperwork before you assume you are out of luck.
Zero, out of your pocket. The Song-Beverly Act shifts the attorney fees and costs onto the maker on a successful claim, which is why the case review costs you nothing and the representation after it does too. You will not see a bill from us for evaluating your repair orders or carrying the claim forward.
