What Happens if a Dealership Can't Fix a Car Under Warranty?

You bought or leased your car so you could rely on it, not spend your free time at the service drive. If the dealership keeps your vehicle for days and hands it back with the same problem, you are not stuck. California law gives you clear rights when a manufacturer cannot fix a warranty defect.

What it really means when the dealer cannot fix your car

A new or certified pre-owned vehicle typically comes with a manufacturer’s warranty. That warranty is a promise to repair defects that arise during the warranty period at no cost to you. The dealer is the manufacturer’s authorized repair facility. If a covered defect is not fixed after reasonable opportunities, California’s lemon law steps in.

Key terms in plain English:

• Express warranty: The written warranty in your owner’s materials. It lists what is covered and for how long.
• Implied warranty of merchantability: A built-in legal promise that the car is fit for ordinary driving. In California, it applies to new vehicles and many used vehicle sales too. See Cal. Civ. Code §1791.1.
• Nonconformity: A defect covered by the warranty that substantially impairs use, value, or safety. This is the core lemon law trigger.

In short, if your car has a warranty-covered defect that the dealer cannot fix after a reasonable number of attempts, the manufacturer must repurchase or replace the vehicle under the Song-Beverly Consumer Warranty Act. See Cal. Civ. Code §§1790-1795.8.

Your core California rights when repairs do not fix the problem

California’s Song-Beverly Act requires manufacturers to promptly repair warranty defects. If they cannot, they must offer a repurchase or replacement. See Cal. Civ. Code §1793.2(d)(2). You do not have to accept endless visits to the service lane.

The Tanner Consumer Protection Act presumption

California creates a helpful presumption that your vehicle is a lemon if, within the first 18 months or 18,000 miles after delivery, whichever comes first, any of the following happens for the same nonconformity. See Cal. Civ. Code §1793.22(b).

• 4 or more repair attempts, or
• 2 or more attempts for a defect likely to cause death or serious bodily injury if the car is driven, or
• 30 or more total days out of service for repair, whether consecutive or not.

If these numbers are met, the law presumes the manufacturer had a reasonable number of chances. Under some circumstances, to use this presumption in court the manufacturer may argue you first need to try its state-certified arbitration program if it maintains one. See Cal. Civ. Code §1793.22(c). Many manufacturers do not have a certified program. Even if you never use arbitration, you can still prove your case without the presumption.

You still have rights outside the presumption window

If your defect started after 18 months or 18,000 miles, or if the numbers above are not met, you can still win under Song-Beverly by showing the manufacturer had a reasonable number of repair opportunities and failed to fix the defect. A serious safety defect that persists after even 1 or 2 visits can be enough, based on facts.

Federal warranty protection

The Magnuson-Moss Warranty Act, a federal law, also protects you when a manufacturer does not honor a written warranty. See 15 U.S.C. §§2301-2312. Magnuson-Moss allows recovery for breach of warranty even if the state lemon law presumption does not apply.

Implied warranty and used vehicles

California’s implied warranty of merchantability means a vehicle must be fit to drive safely for ordinary purposes. See Cal. Civ. Code §1791.1. For many used vehicle sales that include a warranty, implied warranties cannot be disclaimed and last at least 30 days, and often longer depending on the sale. If your used vehicle was sold “as is,” your rights depend on the facts, but if it has a remaining manufacturer’s warranty or was sold as certified, lemon law protections can still apply.

Small business vehicles

Song-Beverly can also cover small business use. If your business has five or fewer vehicles registered in California and the defective vehicle has a gross vehicle weight under 10,000 pounds, you may qualify. See Cal. Civ. Code §1793.22(e)(2).

What counts as a reasonable number of repair attempts

Courts look at the whole story:

• How many times did you present the car for the same issue?
• How long was it out of service in total?
• How severe is the defect? Does it affect safety, drivability, or value?
• Did the dealer acknowledge the concern and attempt a repair, or say “no trouble found”?
• Were parts backordered or software updates delayed?

Important points:

• Intermittent problems still count. A dealer’s “could not duplicate” visit is a repair attempt if you presented a specific complaint and they tried to diagnose it. Get those words on the repair order.
• Software fixes count. Over-the-air or in-dealer software updates are repair attempts. If an update was required to correct a defect and it failed to do so, that is relevant.
• Parts delays count. Days when the car sits at the dealer waiting for parts or engineering approval count toward the 30-day threshold.
• Authorized facilities. You can use any authorized dealer for your brand. The law does not require you to use only the selling dealer.

What the manufacturer must do if the dealer cannot fix the defect

If the manufacturer cannot conform the vehicle to warranty after a reasonable number of attempts, it must promptly do one of the following. See Cal. Civ. Code §1793.2(d)(2).

• Repurchase, also called buyback. The manufacturer refunds what you paid for the car, including down payment, monthly payments made, and the balance of your loan or lease, plus tax, license, registration, and other official fees. You also recover incidental damages like towing and rental. The refund is reduced by a mileage offset for your use before the first repair attempt for the defect.
• Replace. The manufacturer provides a substantially identical new vehicle, and pays taxes and fees. You pay a mileage offset for use before the first repair attempt.

You do not have to accept a replacement if you prefer repurchase, and vice versa.

What is the mileage offset and how is it calculated

California uses a simple formula for the mileage charge. See Cal. Civ. Code §1793.2(d)(2)(C).

• Mileage offset = (Miles at first repair attempt for the defect ÷ 120,000) × cash price of the vehicle.

Example:

• Cash price: 40,000 dollars
• Miles at first repair attempt for the qualifying defect: 6,000
• Offset = 6,000 ÷ 120,000 × 40,000 = 0.05 × 40,000 = 2,000 dollars
• In a repurchase, your refund would be the total paid, minus 2,000 dollars, plus incidental damages.

Incidental damages include reasonable towing, rental, ride share, and repair-related costs. See Cal. Civ. Code §1794.

What about a cash-and-keep settlement

Many consumers prefer to keep the car if the defect is livable but they lost time and value. The law allows recovery for breach of warranty and for incidental damages, and cases often resolve by a cash payment plus continued warranty coverage. Whether this makes sense depends on the defect and your goals.

Safety defects and fast action

If your issue affects steering, brakes, unintended acceleration, fuel leaks, airbag faults, or anything likely to cause serious injury, the two-visit rule under the Tanner Act presumption may apply. See Cal. Civ. Code §1793.22(b). If the dealer tries twice and the issue persists, you likely have a strong claim. You do not need to wait for four visits.

Step-by-step: what to do when the dealer cannot fix your car

Follow these steps to protect your rights and build a strong record.

1) Keep every document

Create a file with:

• Purchase or lease contract
• Registration
• All warranty booklets and recall notices
• Every repair order and invoice, even if it says “no trouble found”
• Loaner or rental receipts
• Towing receipts and out-of-pocket costs
• Photos, videos, and sound clips of the problem
• A simple log of dates, symptoms, and conversations

Under California’s Automotive Repair Act, the shop must give you a written estimate and final invoice with the complaint, diagnosis, and work performed. See Bus. & Prof. Code §9884.9. If they will not write it up, ask for a manager and insist on a repair order.

2) Present the vehicle again and be precise

Each time:

• Describe the concern the same way. Example: “Vehicle shudders between 25 and 40 mph under light acceleration.”
• Ask the advisor to write your words on the repair order.
• Ask to test drive with a technician if the issue is intermittent.
• Request that they document any software update, TSB, or parts backorder.

3) Ask for escalation

If the same defect persists:

• Ask the dealer to open a case with the manufacturer.
• Request a field technical specialist visit.
• Ask for copies of any Technical Service Bulletins applied.

4) Track days out of service

Note drop-off and pick-up dates. If your car is immobilized and waiting for a part, those days count. If your advisor suggests closing the repair order and reopening it later, ask them to keep the same repair order open while the car remains in their possession.

5) Request a loaner or rental coverage

Most warranties include rental or loaner coverage when the vehicle is undriveable or kept overnight. Keep all receipts. These are recoverable as incidental damages under Cal. Civ. Code §1794.

6) Write to the manufacturer

Send a short letter or email to the manufacturer’s customer care asking for a repurchase or replacement. Include:

• Your name, VIN, and contact info
• A summary of the defect
• Dates and mileages of each repair attempt
• A total of days out of service
• Your requested remedy: repurchase or replacement

Keep a copy. Send by certified mail if possible.

Simple template starter:

“I am requesting a repurchase under the California lemon law. My 2023 [Make Model], VIN [VIN], has been in for [defect] on [dates] and remains unrepaired after [number] attempts, for a total of [number] days out of service. Please contact me to arrange the statutory remedy.”

7) Consider arbitration

Some manufacturers offer arbitration programs. If the program is state-certified, using it can help you use the Tanner Act presumption in court. See Cal. Civ. Code §1793.22(c). Arbitration is usually nonbinding. You do not have to accept an unfavorable decision. Many programs are not certified, and you are not required to use them.

8) Talk with a lemon law attorney

California’s lemon law has a fee-shifting provision. If you prevail, the manufacturer pays your reasonable attorney’s fees and costs. See Cal. Civ. Code §1794(d). That is why reputable firms like ours offer no out-of-pocket fees. An attorney can evaluate your file, handle communications, and push for the right remedy quickly.

Real-world scenarios

Scenario 1: Transmission shudder

• Facts: New SUV, shudders and slips between gears. Dealer performs 3 software flashes and 1 fluid service. Problem persists. Total days out of service: 28. First repair at 5,200 miles. Price: 45,000 dollars.
• Analysis: You are close to the 30-day presumption and already have 4 attempts. If there is another visit or a few more days out, the presumption under §1793.22 likely applies. Even now, you can argue reasonable attempts failed. Mileage offset if repurchased at 5,200 miles would be 5,200 ÷ 120,000 × 45,000 = 1,950 dollars.

Scenario 2: Airbag warning light

• Facts: Car triggers airbag fault. Dealer replaces sensor. Light returns within a week. Dealer replaces harness. Light returns again. Total attempts: 2 within first 10,000 miles.
• Analysis: This is a safety defect likely to cause serious injury if airbags fail. Two attempts in the first 18 months or 18,000 miles can trigger the presumption. See §1793.22(b).

Scenario 3: Parts on backorder

• Facts: Brake booster failure. Car sits 37 days waiting for parts with the repair order open.
• Analysis: The 30-day out-of-service threshold is met. Parts shortages do not excuse the manufacturer’s duty to timely repair. You likely qualify for a buyback or replacement under §1793.2(d)(2).

Special situations and practical answers

The dealer keeps saying “no trouble found”

Ask to ride with a technician. Provide video of the symptom when safe to capture. Make sure the repair order states your complaint clearly. “Could not duplicate” still documents a repair attempt. If the problem is intermittent, that fact supports your case rather than hurting it.

The issue started near the end of warranty

If you report the defect while under warranty and the dealer documents it, continued repair attempts can count even after the warranty expires. You can still bring claims under Song-Beverly and Magnuson-Moss.

Aftermarket parts or modifications

Modifications can complicate claims, but they do not void everything. The manufacturer must show the mod caused the defect they are denying. Warranty coverage for unrelated systems still applies.

Leased vehicles

Leases are fully covered. Remedies include repurchase or replacement. In a lease buyback, the manufacturer pays off the lease and refunds what you paid, minus the mileage offset.

Small businesses and work trucks

If your business owns five or fewer vehicles and the defective vehicle weighs under 10,000 pounds GVWR, you may qualify for lemon remedies just like a consumer. See Cal. Civ. Code §1793.22(e)(2).

Documentation tips that win cases

• Use one consistent phrase to describe the defect on every visit.
• Photograph the odometer at drop-off and pick-up.
• Ask the advisor to list all fault codes pulled and all parts replaced.
• Keep a running day count for each visit.
• Save voicemails and emails with the dealer and manufacturer.
• Do not agree to close a repair order until you pick up the car.

How recent California updates fit in

California continues to strengthen consumer protections around vehicle sales and service. Two recent measures to be aware of:

• AB 1755 (2024). This legislation reflects California’s ongoing push for fair warranty practices and clearer information in modern, software-driven vehicles. It complements existing rights by promoting better documentation and transparency in repairs. It does not change your core lemon law remedies under Song-Beverly.
• SB 766, also referred to as the CARS Act. This measure increases accountability in the automotive marketplace, including stronger disclosure and consumer protection standards related to vehicle condition and safety. Like AB 1755, it works alongside, not in place of, your lemon law rights.

The takeaway: documents and transparency matter more than ever. Keep thorough records and insist on detailed repair orders. Your rights to repurchase or replacement still come from Cal. Civ. Code §§1790-1795.8, with the Tanner Act presumption in §1793.22.

Frequently asked questions

Do I have to give the dealer unlimited chances to fix my car

No. California does not require endless repair attempts. The Tanner Act presumption uses 4 attempts for most issues, 2 for safety issues, or 30 days out of service within 18 months or 18,000 miles. Even if you do not meet those exact numbers, the law only requires a reasonable number of opportunities, not unlimited.

Does the lemon law apply if I bought the car used

Often yes. If the vehicle is still under the manufacturer’s warranty, or it was sold as certified pre-owned, Song-Beverly can apply. Many used sales also include an implied warranty of merchantability that requires basic safety and drivability. Your specific documents matter, so gather your purchase contract and warranty booklet.

What if the dealer says the car is “operating as designed”

Ask them to put that in writing on the repair order. If a condition substantially impairs use, value, or safety, “operating as designed” is not a defense. Manufacturers sometimes issue technical service bulletins or software updates to correct exactly these kinds of concerns. Those efforts count as repair attempts.

How long do I have to bring a lemon law claim

California has a four-year statute of limitations on breach of warranty claims. It typically runs from when the manufacturer failed to fix the defect within a reasonable time or number of attempts. The timeline can be complex, so do not delay in getting advice.

Will I have to pay for a lawyer

If you prevail under California’s lemon law or under Magnuson-Moss, the manufacturer pays your reasonable attorney’s fees and costs. See Cal. Civ. Code §1794(d) and 15 U.S.C. §2310(d). At LemonLaws.com, we offer no out-of-pocket fees, which lets you focus on your case, not the cost.
