California Lemon Law for Repeated Ignition Switch Failures

Repeated ignition switch problems can turn every drive into a guessing game—will the car start, will it stall, will the key get stuck? If you’re in California and you’ve been back to the dealer multiple times for the same ignition switch issue, the California Lemon Law may offer protections. Below, ZapLemon explains how this law works with ignition switch failures and how to document your repairs and warranty coverage in a way that’s easy to manage. This article is for general information only and isn’t legal advice.

California Lemon Law for Repeated Ignition Switch Failures

Ignition switch defects show up in familiar ways: the vehicle won’t start, accessories flicker on and off, the engine cuts out while driving, the key won’t turn or gets stuck, or warning lights appear with no clear fix. These problems aren’t just inconvenient—they can be safety risks, especially if a switch failure causes stalling at speed or cuts power to steering and airbags. When the same ignition switch issue keeps returning after dealer visits, it’s a signal to learn how California’s Lemon Law could apply.

In California, the Song-Beverly Consumer Warranty Act (often called the California Lemon Law) generally requires the manufacturer to repair defects that arise during the warranty period. If a defect substantially impairs the use, value, or safety of the vehicle and the manufacturer (through its authorized dealer) can’t fix it after a reasonable number of attempts, you may be entitled to remedies such as a repurchase or replacement. California also has a “rebuttable presumption” with common guideposts: typically four or more repair attempts for the same issue, two or more attempts for a defect that could cause death or serious injury, or more than 30 total days out of service—usually within the first 18 months or 18,000 miles. These are guidelines, not hard-and-fast requirements, and every situation is fact-specific.

With ignition switches, a “reasonable number of repair attempts” might include repeated visits where the dealer replaces the switch, updates software, or addresses related electrical components, but the symptoms return. Keep in mind the manufacturer must be given a fair opportunity to fix the problem, and repairs generally must be performed by an authorized dealer while the vehicle is under warranty. If your vehicle has an ignition switch recall or technical service bulletin (TSB), those repairs should be covered—but if the defect persists despite those efforts, California Lemon Law may still come into play. For an evaluation tailored to your circumstances, consider contacting ZapLemon to discuss next steps.

How to Track Dealer Repairs and Warranty Coverage

Start by building a simple paper or digital file for your vehicle. Each time you visit the dealer, ask for a complete Repair Order (RO) showing the “customer complaint,” the “cause,” and the “correction,” along with dates and odometer readings. Note every day your car is in the shop (including waiting for parts) and save towing, rental, and rideshare receipts. If the ignition switch causes intermittent problems, record short videos when symptoms occur and keep a dated log describing what happened, the conditions (speed, weather, fuel level), and any warning lights.

Check the warranty booklet that came with your vehicle to confirm what’s covered and for how long. An ignition switch issue often falls under the basic “bumper-to-bumper” warranty, but related failures can implicate powertrain or emissions coverage depending on the vehicle. If the manufacturer has issued a recall or TSB for your ignition switch, repairs are typically free, but a recall fix does not automatically resolve persistent defects or limit your rights under the Lemon Law. Extended service contracts, certified pre-owned warranties, and goodwill policies can also affect who pays for repairs—review those documents and keep copies handy.

Communicate clearly with the dealer. When you drop off the car, describe the ignition symptoms in plain terms and ask the service advisor to write your exact complaint on the RO. If the vehicle feels unsafe, ask about towing rather than driving it in. After each visit, verify the RO lists the dates in and out, parts replaced, and software updates performed. Keep all communications—emails, texts, and voicemails—and consider sending a polite written notice to the manufacturer’s customer care if the problem persists. Better records make it easier to evaluate whether your situation fits California Lemon Law standards. If you want help reviewing your documents, you can reach out to ZapLemon for a consultation.
