My Nissan Altima has serious, ongoing safety issues where the vehicle will unexpectedly and aggressively apply the brakes on its own while I am driving, including on highways and regular roads. This defect happens without my input, without warning, and creates a major risk of being rear-ended, losing control of the vehicle, or causing a serious accident. This issue is Not minor. It is a life-threatening malfunction that makes the vehicle unsafe to operate. I have taken the vehicle to authorized Nissan dealerships for diagnosis and repair on multiple occasions: Repair Dates 2021-2025 at Passport Nissan of Alexandria 150 S Pickett St Alexandria, VA Location Despite these visits, the problem continues. Nissan’s failure to diagnose or repair this critical break/self-braking issue over several years constitutes: •Failure to remedy a known safety defect •Breach of warranty •Violation of consumer protection laws •Negligence regarding driver and public safety A vehicle that breaks on its own, especially at highway speeds – is not safe, not reliable, and not roadworthy. Because Nissan has had more than a reasonable opportunity since 2021 to correct this defect and has failed to do so, I am demanding that Nissan: 1.Buy back the vehicle at an amount equal to the remaining loan balance. I do not want to do any upgrade trade ins. This situation has gone on for years and the vehicle is now a clear danger to me and the public and my two minor children who ride in the car with me. I am requesting immediate action and a good-faith resolution.” (NHTSA Complaint #11702906)

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.
Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2021 Nissan Altima:
Once the presumption is triggered, the burden shifts to Nissan to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Nissan must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2021 Nissan Altima qualifies as a lemon under California law, Nissan may be legally required to:
Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.
Step 2: Keep returning for repairs. You must give Nissan a reasonable opportunity to fix the defect. Visit different authorized Nissan dealers if needed and ask for written documentation of each visit.
Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Nissan pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send Nissan a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.
Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.
Yes. Under Cal. Civ. Code § 1794(d), Nissan is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.
Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.
California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
