Are Software Glitches and Electrical Problems Covered Under California’s Lemon Law?

Driving in San Diego is already a headache, but when your new car acts up with a mind of its own, the frustration reaches a new level. I hear it all the time from clients: a new vehicle that stalls, an infotainment screen that freezes, or a battery that constantly drains. These aren’t the classic “transmission died” problems of a decade ago; they are modern nightmares often tied to complex software glitches and electrical failures.

If you’re dealing with a high-tech vehicle that feels like a constant experiment, you’re likely wondering: Are recurring electrical and computer problems covered by the Lemon Law in California? The short answer is a resounding yes, but understanding how they qualify is key to getting you out of that bad car.

The Scope of a “Nonconformity” Under California Law

California’s Lemon Law covers any vehicle defect, called a nonconformity, regardless of whether it is mechanical, structural, or digital. A nonconformity is a failure to meet the warranty, meaning recurring software bugs or electrical malfunctions can qualify a car as a lemon if they are deemed “substantial.”

For a defect to be substantial, it must substantially impair the use, value, or safety of the vehicle:

• Use: The issue prevents the car from being driven as intended (e.g., a glitch forcing “limp home” mode, or a freezing infotainment system that controls essential functions, such as the rearview camera).
• Value: The presence of persistent error codes or a history of complex electrical repairs significantly lowers the car’s resale value.
• Safety: The issue directly impacts safety (e.g., sensor failures disabling airbags, power steering, or brake assist, or sudden engine power loss due to software).

If your car’s electrical or computer issue meets any of these criteria, it forms the basis for a Lemon Law case.

The “Reasonable Number of Repair Attempts” Requirement

It’s not enough to just have a defect. To trigger the Lemon Law, you must give the manufacturer or its authorized dealer a reasonable opportunity to fix the problem. This is often where clients get confused or frustrated.

California law employs a helpful set of presumptions to define what constitutes a “reasonable” effort on your part. If these conditions are met within the first 18 months or 18,000 miles, it is legally presumed that your vehicle is a lemon, shifting the burden of proof to the manufacturer.

The presumption is met if any of the following apply:

1. The manufacturer or dealer has made two or more attempts to repair a defect that threatens life or safety.
2. The manufacturer or dealer has made four or more attempts to repair the same non-safety-related defect (like a malfunctioning onboard computer).
3. The vehicle has been out of service for repairs for a total of more than 30 calendar days since the date of delivery.

However, you can still have a valid Lemon Law claim even if the presumption is not met, so long as the records show that you gave the manufacturer a “reasonable opportunity” to repair the defect and they weren’t able to do get the job done.  This is where an analysis by an experienced Lemon Law attorney is vital.

Think about those frustrating back-and-forth trips to the dealership. Every time they try to “reflash” the computer or replace an electrical component, that visit counts toward your repair attempts. These detailed repair orders are the most crucial evidence in your case. I cannot stress enough: keep every single service receipt!

The Role of Modern Vehicle Technology

Modern vehicles are computers on wheels. A decade ago, an electrical problem might have been as simple as a blown fuse. Today, it’s a sophisticated network of sensors, modules, and code. This complexity plays directly into the Lemon Law:

• Intermittent Glitches: Since software issues can be sporadic, dealers often struggle to replicate and resolve them. You might drive away from the dealership, and the same sensor error pops up on the 163 freeway. These recurring, unfixable problems are the classic definition of a lemon.
• Over-the-Air (OTA) Updates: Sometimes, manufacturers attempt to resolve issues with a software update. If the update fails or causes a new problem, the vehicle will still  be covered under the warranty. A simple software patch does not absolve the manufacturer of its responsibility under the Lemon Law. It must be fixed, or you will receive a replacement or a refund.
