“We couldn’t find anything wrong.”

Five words, and your car goes back in the driveway with the same shudder, the same warning light, the same noise you have described to three different service advisors. Maybe this time they blamed your driving. Maybe they said the part is on backorder with no date. Maybe they said a software update would take care of it, and it didn’t.

When your dealership won’t fix car problems that are covered by your warranty, it feels like you have run out of moves. You haven’t. California law puts the burden on the manufacturer, not on you, and a dealer’s refusal is often the first piece of evidence in a strong lemon law claim. Handle the next few weeks the right way and you could walk away with a full refund. Handle them the wrong way and you could lose leverage you didn’t know you had.

Here’s exactly what to do, updated for the rules in effect in 2026.

What Changed for California Drivers in 2026

Before the step-by-step, know that the process looks different than it did a few years ago. Three changes matter most:

• Some manufacturers now follow a new set of rules. Laws known as AB 1755 and SB 26 let automakers opt into a new process. If your manufacturer opted in, you have a 30-day written notice step before you can seek civil penalties, mandatory mediation after a lawsuit is filed, and a shorter filing deadline.
• Opt-in status changes every year. The California Department of Consumer Affairs publishes the list of manufacturers who opted in each December. Check the DCA’s new lemon law procedures page rather than guessing.
• Used car coverage got narrower. A 2024 California Supreme Court decision changed who qualifies for a buyback on a used car. More on that below.

Takeaway: Your core right when a dealership won’t fix car defects hasn’t changed. The steps to protect it have.

Why Your Dealership Won’t Fix Car Defects

Understanding the “why” helps you respond. The most common reasons we see:

• “Could not duplicate.” The technician drives it around the block, the problem doesn’t show up, and you get your keys back.
• Warranty pay disputes. Dealers get reimbursed by the manufacturer for warranty work, sometimes at rates they don’t like. Some drag their feet on repairs that won’t pay well.
• Blaming you. Aftermarket parts, missed maintenance, or “driving habits” get cited to deny coverage.
• Parts and technician shortages. This is especially common with EVs, hybrids, and advanced driver assistance systems.
• Software excuses. Over-the-air updates get treated as a fix even when the symptom keeps coming back.

None of these reasons cancel your rights. If the dealership won’t fix car issues that fall under the warranty, the clock on the manufacturer’s obligations keeps running.

Step 1: Get the Refusal on Paper

If your dealership won’t fix car problems and tells you so to your face, document it that day. Ask the service advisor to put the refusal in writing. Many won’t, but asking shows you are serious.

If they refuse, write it down yourself:

• The date and time
• The service advisor’s full name
• Exactly what they said, as close to word for word as you can
• Your mileage

Then send a short, polite email to the service department summarizing the conversation. Now you have a timestamped record they didn’t dispute.

Takeaway: A refusal you can prove is evidence. A refusal you only remember is a story.

Step 2: Make Sure Every Repair Order Tells the Truth

Every California dealership repair issue is won or lost on paperwork. Every time you drop off the car, read the repair order before you sign. It should describe your complaint in your words. “Customer states vehicle hesitates and jerks when accelerating from a stop” is useful. “Check vehicle” is not.

When you pick up the car, get the closing repair order even if they say they did nothing. A visit where the technician couldn’t find the problem still counts.

That point comes from Oregel v. American Isuzu Motors, Inc., and it is one of the most important cases for anyone whose dealership won’t fix car problems it claims it can’t find. Oregel brought his Isuzu in six times for an oil leak. The manufacturer argued only one of those visits counted, because the other times the mechanic just looked for the leak. The court rejected that. Your only job is to give the manufacturer a reasonable chance to repair the car. If its technicians can’t isolate the problem, that is not your fault. The jury also found Isuzu’s refusal to buy back the car was willful and awarded a civil penalty on top of damages.

So every “could not duplicate” invoice isn’t a dead end. It is proof you kept giving them the chance.

Takeaway: Show up, get it in writing, and keep every invoice. That is what builds a lemon law case when a dealer refuses repair.

Step 3: Count Your Repair Attempts and Days Out of Service

California law gives manufacturers a reasonable number of attempts. Under the lemon law presumption, you are generally in strong territory if, within 18 months or 18,000 miles of delivery:

• The same safety defect has been in for repair two or more times, or
• The same defect has been in four or more times, or
• The car has been out of service for more than 30 days total

Those numbers are a guideline, not a floor. You can have a valid claim with fewer visits. Separately, Civil Code § 1793.2 says warranty repairs must be completed within 30 days unless you agree to a delay.

Make a simple log: visit date, mileage in and out, days in the shop, and what the dealer said. When your dealership won’t fix car issues, this log becomes your timeline.

Step 4: Go Over the Dealer’s Head

When a dealership won’t fix car defects, remember the dealer is not the only party responsible. The manufacturer issued your warranty, and the manufacturer owes you the buyback or replacement if the car can’t be fixed.

Look in your owner’s manual or warranty booklet for the manufacturer’s customer assistance contact and written notice address. Send a written complaint describing the defect, your repair history, and the dealer’s refusal. Keep a copy and proof of delivery.

Be careful on customer care phone calls. Be polite, stick to facts, and don’t accept any “goodwill” offer or sign anything on the spot. When your dealership won’t fix car problems and the manufacturer suddenly offers cash, that usually means they know you have a claim.

Step 5: Find Out Which 2026 Rules Apply to You

This is the step most older guides skip. If your manufacturer opted into the AB 1755 process:

• Pre-suit notice. You send the manufacturer a written notice at least 30 days before filing if you want to seek civil penalties. The notice has specific content and delivery requirements. Get it right the first time.
• Mandatory mediation. After a lawsuit is filed and the manufacturer responds, both sides go to mediation within a set window.
• A shorter deadline. Claims generally must be filed within one year after the express warranty expires, and no later than six years from the car’s original delivery.

If your manufacturer didn’t opt in, the traditional lemon law process applies. Either way, missing a step costs you money. For the full background on why these changes happened, read our breakdown of why California lemon law rules changed in 2026.

Takeaway: Check the DCA list, then check your deadline. Don’t assume.

Step 6: Keep the Car and Keep Up the Maintenance

Even when your dealership won’t fix car problems and you are fed up, don’t sell or trade in the car without talking to a lemon law attorney first. Selling can complicate your claim, and under the opt-in rules the manufacturer gets a window to respond to your notice.

Keep doing scheduled maintenance and save every receipt. If a manufacturer is looking for a reason to blame you, a missed oil change hands them one. And if the defect makes the car unsafe to drive, stop driving it and have it towed to the dealer. Your safety comes first.

Bought Used? Read This First

In late 2024, the California Supreme Court decided Rodriguez v. FCA US, LLC. It held that a used car doesn’t qualify for the lemon law’s refund-or-replace remedy just because some of the original factory warranty was left when you bought it.

That is a real setback. But it didn’t erase every option. Certified pre-owned vehicles, cars sold with a new warranty issued at the sale, dealer warranties, and federal warranty claims can still give you a path forward. If you bought used and your dealership won’t fix car defects under warranty, get your paperwork reviewed before you give up.

What You Can Recover

When a dealership won’t fix car defects and the manufacturer can’t either, California law gives you real remedies:

• A buyback. A refund of what you paid, including taxes, fees, and finance charges, minus a small mileage offset for the miles you drove before the first repair visit. Your loan gets paid off.
• A replacement vehicle. A comparable new car.
• Cash and keep. Compensation for the defect while you keep the car.
• Civil penalties. If the manufacturer’s violation was willful, up to two times your damages.
• Attorney’s fees. Paid by the manufacturer when you win.

The Manufacturer Pays Our Fees, Not You

We’ve seen every excuse a service department can come up with. We step in, confront the manufacturer, and push for a fast resolution. Most of our clients never set foot in our office. Everything can be handled remotely.

And California law requires the manufacturer to pay your attorney’s fees when you prevail. When a dealership won’t fix car problems, there is no reason to fight it on your own.
