California Lemon Law rights + next steps

California’s Lemon Law and related consumer protections can apply when a vehicle shows a documented pattern of substantial defects that persist after reasonable repair attempts, or when repeated warranty visits and electrical/safety issues undermine use, value, or safety.

FAQs

How many repair attempts are “enough” in California?

There’s no single magic number. A repeat pattern for the same defect—or a substantial defect that persists despite repairs—can be sufficient, especially when the records show escalating diagnostics and parts replacement.

Do electrical no-start problems qualify under California Lemon Law?

They can. Repeated no-start/battery issues and parasitic-draw complaints may substantially impair use, value, or safety—particularly when documented across multiple visits and the problem recurs.

Does Mountain View matter for my Lemon Law rights?

No. Protections are statewide in California. “Mountain View” is used for local context based on the owner address shown in the service records; service and enforcement can involve any California dealership/service facility.

Could facts like these also raise dealer fraud or repair misconduct concerns?

Sometimes. If your paperwork, charges, or warranty handling don’t match what you were told—or if documentation suggests billing/inspection irregularities—those issues may also be relevant under California consumer law (separate from the defect/warranty claim).

Free case review (California only)

If your Hyundai has repeated electrical failures, no-start issues, or warranty runaround, you may have options under California law. Don’t wait—deadlines apply.

There aren't enough words to describe how grateful I am for finding this firm! Robert and David are amazing. After interviewing a couple of attorneys I realized they were the most honest and dedicated attorneys that truly cared about their clients. I would recommend this firm to anyone. I had a difficult case and because of their knowledge and professionalism, we won the case. They were always there to answer my phone calls, patient and listened to all of my concerns. They are very punctual and prepared attorneys. I had nothing to worry about the day of my hearing because we had everything prepared and ready to present. I am very thankful to have found such a great firm and amazing people like them to work with.

Robert was great. Very knowledgeable and professional. I highly recommend him and his offices.

After getting the runaround from Mercedes and their dealerships, I gave Robert a call on the recommendation of a friend. I told him that Mercedes had told me that my car wasn't a lemon and even with another attorney involved, that they had denied my case.

With Robert's help, I got more money than I even expected faster than I imagined.

Thanks Robert!

Dear Robert,

I wanted to take the time to thank you and your firm for all the hard work and successful outcome we received for my case with Mercedes Benz of North America.

As you know, even though my case was very clear-cut and strong, I could not believe the very difficult time MBZ gave me.

Your expertise in this matter was second to none and I will be happy to refer you business from any of my friends or relatives that may need your services.

Having been told by several attorneys that I did not have a case because "on paper," my Bentley was purchased in Oregon, I called the Lemon Law Auto Fraud Law Firm at the insistence of a friend who kept telling me how good these guys were. I couldn't be happier with this firm, or how they handled my Bentley case!

After they said they would take my case, I decided to research their law office on the internet because so many other attorneys had told me that I didn't have a case. In my research, I found that the two highest rated lemon law firms in Los Angeles were this firm, and the law firm that represents Bentley. That was all I needed to make my final decision.

Both my attorney Robert and his research and development department kept me informed of the developments of my case and their conversations with Bentley. Through their dedication, hard work and thorough knowledge of the lemon laws, my case was settled amicably with Bentley and I am very satisfied with the outcome.

I could not be happier with Robert or his staff at Lemon Law Auto Fraud. I will happily refer him to everyone, and anyone I know who is having problems with their car. These guys are absolutely the best!
