Lemon Law for Failing Ignition Systems

When an ignition system keeps failing—no-starts, stalls at intersections, “key not detected” errors, or a starter that clicks but won’t crank—it’s more than an inconvenience. It can sideline your workday, threaten safety in traffic, and drain your wallet. If these problems repeat under warranty, California’s Lemon Law may offer remedies. Below, ZapLemon explains how the law applies to ignition defects and what to document so you can make informed next steps.

How California Lemon Law Applies to Ignition Failures

California’s Lemon Law (part of the Song-Beverly Consumer Warranty Act) covers new and many used vehicles that develop defects under the manufacturer’s warranty which substantially impair use, value, or safety. Ignition-related defects can qualify when they persist despite repair attempts—for example, intermittent no-starts, engine stalls, ignition coil or module failures, faulty push-button start systems, immobilizer/key fob recognition errors, or chronic misfires tied to ignition components. The key is not just that the defect exists, but that it materially affects your ability to safely and reliably use the car.

The law generally requires that the manufacturer or its authorized dealer get a reasonable number of chances to fix the problem. California also provides a rebuttable “lemon” presumption for certain situations within the first 18 months or 18,000 miles: multiple repair attempts for the same defect, two or more attempts for a defect likely to cause death or serious bodily injury, or 30+ cumulative days out of service may help establish your claim. These are guidelines, not guarantees—facts and timelines matter, and there are exceptions—so understanding your specific situation is important.

If your vehicle qualifies, potential remedies can include a manufacturer buyback (repurchase), a replacement vehicle, or a cash-and-keep settlement, depending on circumstances. The law typically applies to vehicles sold or leased with a manufacturer’s warranty, including many certified pre-owned cars. Because ignition issues can overlap with electronics, security systems, and software updates, the repair history and warranty status are crucial. A consultation can help you understand how these rules might apply to your ignition-related concerns.

What to document and when to contact ZapLemon

Good paperwork is powerful. Keep every repair order and make sure your complaint is written in your own words (e.g., “vehicle stalls at stoplights,” “no-start when hot,” “key fob not detected,” “starter clicks, engine won’t crank”). Track dates, mileage in and out, and the total days your car spends at the shop. Save tow receipts, rental car invoices, and photos or videos of the symptoms—especially intermittent problems that are “unable to duplicate” at the dealership.

Round up your purchase or lease agreement, warranty booklet, any extended coverage documents, recall or Technical Service Bulletin (TSB) notices, and emails or texts with the dealer or manufacturer. Create a simple timeline showing when each ignition issue occurred and what the dealer did. If parts are backordered or the car is repeatedly returned as “no problem found,” note those details—they can matter under the Lemon Law’s “reasonable repair attempts” standard.

Consider contacting ZapLemon if you’ve had repeated ignition failures, the dealer can’t fix or reproduce the issue, you’ve been without your car for extended periods, or safety concerns (like stalling in traffic) have you worried. Deadlines may apply to lemon claims, and a quick conversation can help you understand your options. Speaking with an attorney is the best way to get advice about your situation; an initial consultation can clarify whether your documentation and timeline point toward potential Lemon Law relief.
