Can the Dealer Refuse to Fix My Car Under Warranty?

Published October 19, 2026 · Updated October 19, 2026 · California lemon law

The Short Answer

Signs a Warranty Refusal May Be Wrong

• The car is within the warranty's time and mileage limits
• The part or system is listed as covered in the warranty booklet
• The dealer gave no written reason, or a vague one
• The dealer blamed aftermarket parts that have nothing to do with the problem
• The dealer said it could not find the problem and refused to keep looking
• Another dealer for the same brand treated the problem as covered

What a New Car Warranty Promises

A manufacturer's warranty is a written promise to repair defects in materials or workmanship for a set time or mileage. Most new cars come with a basic warranty that covers most parts and a longer powertrain warranty for the engine, transmission and drive system. There may also be separate coverage for emissions parts, rust, and electric vehicle batteries.

The dealer is the manufacturer's repair shop for warranty work. When you bring a covered problem to an authorized dealer, the manufacturer generally pays the dealer for the repair. That is why the lemon law looks at visits to authorized dealers: those visits are the manufacturer's chances to keep its promise.

California's lemon law adds teeth to that promise. If the manufacturer or its dealers cannot fix a covered defect that substantially impairs use, value or safety after a reasonable number of attempts, Civil Code 1793.2(d)(2) requires the manufacturer to replace the car or buy it back. A refusal to repair a covered defect does not get the manufacturer out of that duty.

Read the warranty booklet that came with the car, or find it on the manufacturer's website. It lists what is covered, what is excluded, and how long each type of coverage lasts. Knowing those terms before a dispute makes it much easier to tell whether a refusal is fair, and it lets you quote the exact language back to the dealer.

Legitimate Reasons a Dealer Can Say No

Not every refusal is wrong. A warranty has limits, and dealers are allowed to apply them. Knowing the common reasons helps you tell a fair denial from an unfair one.

Even when one of these reasons applies, the dealer should explain it. A vague answer like that is not covered, with nothing in writing, is not enough. Ask which warranty term the dealer is relying on and ask to see it.

A refusal for one of these reasons should be specific to your problem. For example, if the dealer blames accident damage, it should be able to point to the damage and explain how it caused the problem. If it blames missed maintenance, ask which service was missed and how that relates to the part that failed. Keep your maintenance receipts handy for exactly this reason.

• Normal wear items, such as brake pads, wiper blades and tires, which are often excluded
• Damage from an accident, flood, fire or vandalism
• Damage caused by misuse, racing, or lack of required maintenance
• Damage caused by an aftermarket part or modification
• The car is past the warranty's time or mileage limit

Refusals That Often Do Not Hold Up

Some refusals are really about convenience. A dealer may not want to take on a hard diagnosis, may be short on technicians, or may be waiting on the manufacturer to approve the work. None of those is a warranty exclusion.

A common one is blaming aftermarket parts. Federal warranty law generally does not let a manufacturer void your whole warranty just because you added a part or had routine maintenance done elsewhere, but it can deny coverage for damage that the part actually caused. The FTC's guide to federal warranty law explains these rules. If a dealer blames a phone charger for a transmission problem, ask how the two are connected.

Another is refusing because the dealer could not find the problem. Under Oregel v. American Isuzu Motors (2001), you do not have to prove the exact technical cause, and a visit where the dealer could not find or fix the problem can still count as an attempt. A dealer saying it cannot duplicate a problem is not the same as proving the problem is not covered.

A third type of refusal is telling you the warranty ended when it has not. Check both the time and the mileage limits. Many powertrain warranties last longer than the basic warranty, and emissions or battery coverage may last longer still. A dealer looking at the wrong warranty is an easy mistake to correct if you have the booklet.

Example: A Refusal Based on a Lift Kit

This is a made-up example. Luis bought a new pickup and added a small aftermarket lift kit at a local shop. Months later, the infotainment screen started rebooting while driving and the backup camera would not display. The dealer told him the warranty was void because of the lift kit and refused to look at the screen.

Luis asked the advisor to write the reason on the repair order. He then called the manufacturer's customer care line, explained that the lift kit had nothing to do with the screen, and got a case number. A second authorized dealer agreed to diagnose the screen under warranty and replaced a module. The rebooting returned a few weeks later.

When Luis called a lemon law firm, the attorney reviewed both repair orders, the written refusal, and the customer care case number. The attorney explained that the refusal, the later repair, and the return of the problem were all part of his repair history. The firm evaluated a claim. This example shows the process only, not a result.

The written refusal turned out to be useful evidence. It showed the first dealer was told about the problem and declined to diagnose it. Combined with the later repair that did not last, it helped show the manufacturer had more than one chance to make the screen work.

How to Push Back Without Hurting Your Case

Stay calm and get everything in writing. A refusal that was only said out loud is hard to prove later. Ask the advisor to write the reason on the repair order or send it by email. If they will not, send your own email that day summarizing the conversation.

Escalate step by step. Ask for the service manager. Then call the manufacturer's customer care line, which is usually listed in the owner's manual. Many manufacturers have field service engineers or regional staff who can review a dealer's decision. Write down every name, date and case number.

You can also go to another authorized dealer for the same brand. Dealers sometimes read the same warranty differently. A second dealer's willingness to do the work can show the first refusal was wrong.

Be polite but firm. Service advisors often have limited authority, and getting angry rarely helps. A calm request to escalate, backed by the warranty language, is usually the fastest way to a second look.

• Ask: which warranty section excludes this repair?
• Ask: can you show me in writing what caused the damage?
• Ask: will you contact the manufacturer's technical line?
• Keep: names, dates, and case numbers for every call

Paying for a Repair Yourself

If the car is unsafe and no authorized dealer will repair it, you may need to pay for a fix to keep driving. Before you do, try to get the refusal in writing and tell the manufacturer. If you pay, keep the receipt, the invoice describing the work, and the old parts if the shop will give them to you.

Keep in mind that repairs at an independent shop, or done yourself, do not count as repair attempts under the lemon law. They do not add to your count. But the cost of a repair the warranty should have covered may be part of what you can recover, since restitution can include incidental damages such as reasonable repair costs under Civil Code 1793.2(d)(2)(B).

Talk to an attorney before paying for a major repair if you can. The decision can affect how the manufacturer responds to a claim, and an attorney may be able to get the manufacturer to reconsider.

If an independent shop finds the cause of a problem the dealer refused to look at, ask the shop for a written diagnosis. You can bring that to an authorized dealer and ask it to perform the warranty repair. The independent visit does not count as an attempt, but the information can help get the car fixed.

When a Refusal Becomes Part of a Lemon Law Claim

A wrongful refusal can help your case in two ways. It shows the manufacturer had a chance to fix the car and did not. And if the manufacturer knew it owed you a repair and refused anyway, a court can award a civil penalty of up to two times actual damages for a willful violation under Civil Code 1794(c). Whether a penalty applies turns on the proof.

If the car qualifies, you can choose a buyback or replacement. When you win, the manufacturer pays your attorney fees, costs and expenses under Civil Code 1794(d). If our firm loses your case, you owe nothing and we never pursue clients for fees.

Watch the timing. Warranty claims generally must be filed within four years under Commercial Code 2725. Bring your warranty booklet, every repair order, and any written refusal to a free case review.

If you are not sure whether a refusal was fair, that is a good reason to call. An attorney who handles warranty cases can usually tell quickly whether the dealer's explanation matches the warranty language.

What to Do if the Dealer Refuses

1. Ask the service advisor to write the exact reason for the refusal on the repair order.
2. Read your warranty booklet and find the section that covers the part or system.
3. Call the manufacturer's customer care line, explain the refusal, and write down the case number.
4. Take the car to a different authorized dealer for a second opinion.
5. If you must pay for a repair to stay safe, keep the receipt and the old parts if possible.
6. Call 877-536-6620 for a free case review if a covered problem is being refused or ignored.

FAQ

Can a dealer void my warranty for using an independent shop for oil changes?

Generally no, as long as the required maintenance was done. Keep receipts for all maintenance in case the dealer asks.

What if the dealer says the problem is normal?

Ask for that statement in writing and get a second opinion from another authorized dealer. Normal for the model is not always the same as working properly.

Does a refused visit count as a repair attempt?

If you presented a covered problem to an authorized dealer, that visit can still be part of your repair history. An attorney can review it.

Can I complain to the manufacturer about a dealer?

Yes. Call the customer care line in your owner's manual and write down the case number.
