If your EV or hybrid is stuck in a “service campaign” loop—back to the dealership for the same update or part, yet the problem keeps returning—you’re not alone. Many California drivers are told a customer satisfaction campaign, software patch, or voluntary service action will fix a defect, only to find the symptom persists. This article explains how California’s lemon law interacts with EV/hybrid service campaigns and what practical steps you can take to document problems. It’s for general information only; for advice about your situation, please contact ZapLemon for a consultation.
California lemon law and EV/Hybrid campaigns
California’s lemon law—part of the Song-Beverly Consumer Warranty Act—generally requires manufacturers to repair defects covered by a new vehicle warranty within a reasonable number of attempts. If a substantial defect that affects use, value, or safety isn’t fixed after reasonable repairs, the law provides remedies such as repurchase or replacement, along with incidental damages in some cases. What counts as “reasonable” depends on the facts, including the number of visits, days out of service, and the seriousness of the defect.
EV and hybrid owners often encounter “service campaigns,” “customer satisfaction programs,” or “software updates” aimed at known issues—think battery management system (BMS) updates, inverter replacements, charging control revisions, heat pump or thermal management fixes, or DC fast-charging throttling patches. These aren’t the same as a safety recall, and they may not be labeled “warranty” at the service desk. Still, if the work is performed to address a defect in a vehicle under warranty, those repair attempts and days out of service can matter when evaluating lemon law rights.
If a service campaign doesn’t actually fix the problem—charging stalls, drive unit hesitation, repeated “vehicle may not restart” warnings, rapid battery degradation, recurring check EV system lights, or thermal runaway mitigation alerts—that ongoing defect may support a lemon-law evaluation. Even when the manufacturer frames it as a goodwill update or voluntary campaign, the result is what matters: Is the defect resolved, or does it keep you from safely using the vehicle as intended? Every case is fact-specific, and timelines, mileage, and warranty coverage all play a role.
Service campaign still not fixed? What to track
Documentation is your best friend. Each time you visit the dealer, ask for a detailed repair order showing your complaint in your own words, the technician’s diagnosis, work performed, parts/software versions installed, and the outcome. Note the date and mileage in and out, and keep track of every day your car is unavailable—including waiting for parts. Save receipts for towing, rentals, rideshares, and charging costs you wouldn’t have incurred but for the defect.
Because EV and hybrid issues can be software-driven, capture details that help tell the story: version numbers before/after updates, photos or videos of warning messages, and any patterns (for example, DC fast charging dropping from 150 kW to 30 kW after 5 minutes, or shutdowns after long highway drives). Ask the dealer, when appropriate, to record BMS data such as State of Health (SOH), cell imbalance, and fault codes. If you use a home charger, note if the issue occurs across multiple stations and networks to rule out a single faulty charger.
Also keep a communication log: case numbers with the manufacturer, emails, texts, and chat transcripts. Track references to technical service bulletins (TSBs), recalls, or expanded coverage notices. Build a simple timeline showing each visit, days out of service, and the symptom you reported. Then review your warranty booklet to understand coverage windows. If the campaign still hasn’t fixed the issue, consider discussing your documentation with a California lemon law attorney. For next steps tailored to your situation, you can contact ZapLemon for a consultation—no commitments, just a conversation about your options.
