Can a vehicle bought for my business get the same lemon law protection as a personal car?

Side-by-Side Comparison

How a Personal Vehicle Claim Works in California

If you bought or leased a new car, truck or SUV for yourself or your family, California's lemon law covers it without any size or fleet test. The question is simply whether the vehicle has a warranty defect that substantially impairs its use, value or safety and that the manufacturer's dealers could not fix after a reasonable number of attempts.

If so, the manufacturer must replace the vehicle or buy it back, and you get to choose the buyback (Civil Code 1793.2(d)(2)). Restitution covers the price paid or payable, collateral charges like sales tax and registration, and incidental damages, minus a mileage offset (Civil Code 1793.2(d)(2)(B)).

Personal vehicle owners can also use the Tanner Act presumption within 18 months or 18,000 miles (Civil Code 1793.22(b)), and they recover attorney fees and costs from the manufacturer if they win (Civil Code 1794(d)).

It does not matter if you sometimes use a personal car for errands related to work. The usual question is simply whether the car was bought or leased new and has a covered defect.

Personal buyers should still keep every repair order and receipt, because the proof is the same no matter who owns the vehicle.

The rules on incidental damages, the 30-day repair limit and the civil penalty for willful violations apply the same way to personal vehicles.

How a Business Vehicle Claim Works

California extends the lemon law's vehicle rules to some business vehicles, but only if two tests are met. First, the business can have no more than five vehicles registered in California. Second, the vehicle must be under 10,000 pounds gross vehicle weight (Civil Code 1793.22(e)(2)).

If both tests are met, the business gets the same remedies as a personal buyer: a buyback or replacement when the defect is not fixed after reasonable attempts. The business that bought or leased the vehicle is usually the one that brings the claim, and the case uses the same proof: repair orders, contracts and records of downtime.

If a business fails either test, the lemon law's business vehicle rule does not apply. That does not always end the matter. Other warranty claims, such as a claim under the written warranty or the federal Magnuson-Moss Warranty Act, may still be possible, so a larger business should still get its situation reviewed.

If you are a sole proprietor and bought the vehicle in your own name, the analysis may look more like a personal vehicle claim. The contract and registration will tell your attorney which rules to look at first.

Rideshare and delivery drivers who use a personal car for gig work are a common gray area. Bring your contract and registration to a review so an attorney can look at your specific facts.

How to Count Vehicles and Check the Weight

The five-vehicle test and the weight limit sound simple, but small businesses often get them wrong. Do the math before you assume you are in or out.

If you are close to the line, such as exactly five vehicles, check the count as of the time you bought the vehicle and today. Ask your attorney which date matters for your situation.

Weight ratings can also differ between trims of the same model. Read the sticker on your actual vehicle, not a brochure.

If your business has grown or shrunk since the purchase, tell your attorney. Changes in the fleet size can raise questions, and it is better to address them early.

When in doubt, write down the count and the weight rating and bring them to a free case review.

• Count vehicles registered to the business in California, not vehicles owned by employees
• Include leased vehicles registered to the business when you count
• Look up the gross vehicle weight rating on the sticker inside the driver's door, not the empty weight
• Remember that many full-size pickups and vans are under 10,000 pounds, while some heavy-duty models are not
• Keep a printout of your business registrations from the DMV in case the count is questioned

Real-World Example: A Contractor and a Commuter

This is a made-up example. Rosa runs a small landscaping company with four pickups registered to the business in California. One of them, bought new last year and rated under 10,000 pounds, keeps losing power when towing a trailer. The dealer has worked on it four times for the same problem.

Because her business has no more than five California-registered vehicles and the truck is under the weight limit, the business vehicle rule in Civil Code 1793.22(e)(2) can apply. Her attorney gathers the purchase contract in the company's name, the repair orders and records showing the days the truck sat in the shop and could not be used for jobs.

Her brother Tomas bought a new sedan for his own commute and has a similar engine problem. He does not need to count vehicles or check weights. His attorney focuses on his repair history and whether it fits the Tanner Act presumption.

This example does not predict a result. It shows that business owners have one extra step: proving that the business fits inside the size and weight limits.

Rosa's records of lost jobs do not change the legal test, but they help show how the defect affected the use of the truck.

Common Mistakes Business Owners Make

Business owners are busy, and a broken work truck costs them money every day. That pressure can lead to choices that weaken a claim.

Another mistake is letting employees drive a problem vehicle without telling them to report every symptom. Ask drivers to write down the date, mileage and what happened, so you can give the dealer a clear complaint.

Business owners also sometimes assume the claim costs too much to pursue. The manufacturer pays attorney fees and costs when the buyer wins (Civil Code 1794(d)), so cost should not stop you from getting a review.

None of these mistakes has to end a claim, but each one can make it harder or slower. Fixing the habit now protects the next repair visit and the one after that.

• Assuming a company vehicle can never qualify under the lemon law
• Paying an independent shop to get the truck back on the road instead of using the warranty
• Not keeping records of jobs lost or rentals needed while the vehicle was down
• Trading the vehicle in before talking to a lemon law attorney
• Adding upfitting or modifications that the manufacturer later blames for the problem

Documents a Business Should Gather

Business vehicle claims need the same core records as personal claims, plus proof that the business fits the size and weight limits. Pulling these together before your case review saves time and avoids surprises.

If a bookkeeper or office manager handles vehicle paperwork, ask them to gather the registrations and repair invoices at the same time. Repair orders should be in the name on the contract whenever possible.

Make digital copies of everything and store them where more than one person at the business can find them. If a key employee leaves, the records should not leave with them.

Label each repair order with the vehicle and date so they are easy to sort.

If the business has an accountant, the accountant's records of vehicle purchases and registrations can also help confirm the fleet count. Ask for a simple list of every vehicle and when it was added or sold.

• The purchase or lease contract in the business's name
• DMV registrations for every vehicle the business has in California
• The door sticker or spec sheet showing gross vehicle weight rating
• Every repair order for the defect, with dates and mileage
• Rental, towing and lost-job records tied to the breakdowns
• Any letters or emails with the dealer or manufacturer

Step-by-Step: What to Do Next

Start by confirming who is named on the purchase or lease contract. If it is the business, gather proof of how many vehicles the business has registered in California and the vehicle's gross vehicle weight rating.

Next, collect every repair order. Make sure each one describes your complaint in your words, shows the mileage, and lists the dates in and out. Repairs must be completed within 30 days unless you agree otherwise (Civil Code 1793.2(b)), so track how long the vehicle sits at the dealer.

Then write down the business impact: rentals, missed jobs, towing and other costs. Some of these may count as incidental damages in a buyback, and others may be part of settlement talks.

Finally, talk to a lemon law attorney before you sell, trade or modify the vehicle. A free case review can tell you whether the business vehicle rule applies, and if it does not, whether another warranty claim makes sense. For manufacturers that opted in to the AB 1755 process, there are also pre-lawsuit steps under Code of Civil Procedure 871.20 and following that your attorney will handle.

Keep in mind that the statute of limitations for warranty claims is generally four years (Commercial Code 2725).

FAQ

My business has six vehicles. Am I out of luck?

The lemon law's business vehicle rule would not apply, but other warranty claims may. Talk to a lemon law attorney.

Is a heavy-duty truck covered?

Not under the business vehicle rule if it is 10,000 pounds gross vehicle weight or more. Check the weight rating on the door sticker.

Does it matter whose name is on the contract?

Yes. The person or business named on the purchase or lease contract is usually the one who brings the claim.
