Automobile Lemon Law for Repetitive Malfunctions

If your car keeps visiting the shop for the same nagging issue, you’re not alone. Under California’s Lemon Law, repetitive malfunctions can be a sign that a vehicle isn’t living up to its warranty. This article explains what “repetitive” means in plain English and offers practical steps to document repairs so you can protect your rights—without giving legal advice. ZapLemon helps California drivers make sense of the process and decide on next steps through a personalized consultation.

What Repetitive Malfunctions Mean Under CA Law

California’s Lemon Law—part of the Song-Beverly Consumer Warranty Act—generally protects consumers when a vehicle has defects covered by the manufacturer’s warranty that substantially impair use, value, or safety, and the manufacturer (through its dealers) can’t fix them after a reasonable number of attempts. “Repetitive malfunctions” refers to the same or a substantially similar problem that keeps coming back despite repair visits. Think of a transmission that slips again after being “fixed,” a recurring check-engine light for the same code, or brake shudder that returns shortly after service.

The law also includes a helpful “presumption” during the first 18 months or 18,000 miles (whichever comes first). During this period, California presumes a vehicle may be a lemon if: the manufacturer had four or more attempts to repair the same issue; or two or more attempts for a defect that could cause death or serious bodily injury; or the vehicle was out of service for repairs for a total of 30 or more days. This presumption isn’t the only pathway—claims outside these windows can still be viable—but it shows how the state looks at repeated, unresolved defects.

“Repetitive” doesn’t always mean the exact same part fails in the exact same way. What often matters is whether the underlying issue or symptom—stalling, overheating, electrical shutdown, steering pull—recurs and remains unresolved under warranty. Both new and many used/CPO vehicles can be covered when the manufacturer’s warranty is still in effect. If repairs don’t fix the problem after reasonable opportunities, remedies can include repurchase, replacement, or a negotiated cash resolution, depending on the facts. Every situation is unique, so a consultation is key.

Steps to Document Repairs and Protect Your Claim

Start documenting from the first sign of trouble. Keep a simple log with dates, mileage, the conditions when the problem happens (speed, temperature, terrain), and what you experienced (e.g., “vehicle hesitated merging onto highway; check-engine light; P0302 code previously”). Photos or short videos of warning lights, noises, or smoke can help describe intermittent issues. When you arrive at the dealership, clearly explain the symptoms and when they occur; if possible, ask to test-drive with a technician so they can duplicate the concern.

Always ask for a written repair order when you drop off the car and a final invoice when you pick it up—every time. Review both to ensure your complaint is captured in your own words under “customer states,” and that the technician’s findings and repair actions are recorded. “No problem found” or “could not duplicate” visits still count as repair attempts, so keep those too. Track total days out of service, save tow and rental receipts, and retain warranty booklets, recall notices, and any communications with the manufacturer.

Report issues promptly, especially while under warranty. Check warranty status using your VIN on the manufacturer’s website and keep up with scheduled maintenance to avoid disputes. Avoid modifications or aftermarket tunes that could complicate coverage. Be mindful that legal deadlines may apply, and each case turns on its specific facts and documents. If your vehicle keeps going back for the same or similar problem, a consultation with ZapLemon can help you understand your options and next steps under California law.
