Navigating California Lemon Law for Electric Vehicles (EVs): Battery Degradation and Software Bricking
Under California's Song-Beverly Consumer Warranty Act, electric vehicles are fully covered. If an EV suffers from unfixable battery degradation or software bricking, you may be entitled to a full refund or vehicle replacement.
Electric vehicles (EVs) have revolutionized the way Californians drive. From the tech-heavy streets of San Jose to the sprawling freeways of Los Angeles, EVs are everywhere. However, unlike traditional gas-powered cars, EVs rely heavily on complex software systems and massive high-voltage batteries. When these systems fail, the vehicle can become completely undrivable. Many EV owners mistakenly believe that because their car lacks a traditional engine, it is not covered by the standard lemon laws.
This is simply not true. California has some of the strongest consumer protection laws in the nation, and they adapt perfectly to modern EV architecture. If you are stuck paying a high monthly note for a high-tech car that spends more time at the dealership than in your driveway, you have legal rights. Navigating these claims can be highly technical, so utilizing our directory to find an experienced California lemon law attorney is a smart first step.
How the Song-Beverly Act Applies to EVs
In California, lemon law claims are governed by the Song-Beverly Consumer Warranty Act, specifically found in Cal. Civ. Code § 1793.22. The law states that if a manufacturer cannot repair a defect that "substantially impairs the use, value, or safety" of the vehicle after a reasonable number of attempts, they must buy it back or replace it.
For an EV, the "engine" is the battery, and the "transmission" is often the software controlling the powertrain. If a software glitch causes the car to lose power on the freeway, or if the battery degrades drastically faster than the manufacturer's warranty promises, the vehicle is legally impaired. The law does not care if the defect is mechanical or digital; it only cares that the manufacturer sold you a defective product.
EV Micro-Niche Defects in California
Different electric vehicle manufacturers face unique, recurring problems. Here is how California lemon law applies to specific high-profile EV defects.
Tesla Phantom Braking
Many Tesla drivers in areas like Orange County and San Francisco have reported terrifying instances of "phantom braking," where the vehicle's Autopilot or Full Self-Driving (FSD) software aggressively slams on the brakes for no reason on the highway. This is a massive safety hazard. Because this defect poses a risk of death or serious injury, it may only take two unsuccessful repair attempts by a Tesla Service Center before the vehicle qualifies as a lemon under California law.
Rivian Software Bricking During Updates
Rivian trucks and SUVs rely heavily on Over-The-Air (OTA) software updates. Sometimes, a pushed update fails and "bricks" the vehicle, leaving it completely unresponsive and unable to shift into gear. If your Rivian requires a tow to a service center in Sacramento or San Diego because a software update fried the internal computers, and the manufacturer cannot permanently stabilize the system, you may have a valid lemon law claim based on the loss of vehicle use.
Lucid Battery Charging Limitations
Lucid vehicles are marketed with industry-leading battery range. However, if a manufacturing defect causes the high-voltage battery to artificially limit its charging capacity-for example, refusing to charge past 60%-this drastically reduces the value and utility of the car. If this range anxiety is caused by a hardware defect rather than normal usage, the California Department of Consumer Affairs, Sacramento generally views this as a substantial impairment.
The Legal Process for EV Lemon Claims
To successfully force a buyback, you generally need to follow a specific timeline of events.
- Step 1: Document Every Glitch. For EVs, you must take photos or videos of the error messages on the main screen. This is crucial evidence.
- Step 2: Take It to an Authorized Dealer. You must give the manufacturer a chance to fix it. Ensure the service advisor writes down your exact complaint on the repair order.
- Step 3: Track the Days Out of Service. Under California law, if your EV is in the shop for cumulative total of more than 30 days within the first 18 months or 18,000 miles, it is presumed to be a lemon.
- Step 4: File a Civil Complaint. If the manufacturer refuses to buy the vehicle back, your attorney can file a lawsuit in a local court, such as the Superior Court of California, County of Los Angeles, Los Angeles. You may also need to submit Form INV 172A, California, Department of Motor Vehicles, Record of Complaint Form if filing a complaint with the DMV.
| EV Defect Type | Impact on Vehicle | Qualifies for CA Lemon Law? |
|---|---|---|
| Battery Degradation (Defective) | Massive loss of range unexpectedly | Yes (Substantial impairment of use/value) |
| Phantom Braking (Software) | Sudden stops on the highway | Yes (Substantial safety impairment) |
| Broken Infotainment Screen | Cannot control AC or see speedometer | Generally Yes (Controls critical vehicle functions) |
| Normal Battery Aging | Slight range loss over 5 years | No (Considered normal wear and tear) |
Do I have to pay attorney fees for a California lemon law claim?
Generally, no. The Song-Beverly Act contains a fee-shifting provision. This means that if you win your case, the manufacturer is legally required to pay your attorney's fees and costs, not you.
What if the manufacturer fixed the EV with an Over-The-Air update?
If an OTA update permanently fixes the issue before it qualifies as a lemon, you generally do not have a claim. However, if the update fails to fix the issue or creates new defects, your claim remains valid.
Can I claim a lemon if I bought my EV used?
Generally, no. Under the California Supreme Court ruling in Rodriguez v. FCA US, LLC, 17 Cal. 5th 189 (CA Supreme Court 2024), used vehicles purchased with the balance of an unexpired factory warranty do not qualify as a "new motor vehicle" under Cal. Civ. Code § 1793.22(e)(2). Consequently, buyers of used EVs cannot demand a statutory buyback or replacement under Cal. Civ. Code § 1793.2(d)(2). The statutory refund-or-replace remedy applies only to new vehicles or Certified Pre-Owned (CPO) vehicles sold with an express written warranty issued directly by the manufacturer or authorized dealer at the time of sale.
