Today’s cars are computers on wheels, and many manufacturers now push over-the-air (OTA) software updates to fix bugs without a trip to the dealership. That convenience can be great—until the same problem keeps coming back. At ZapLemon, our lemon car lawyers are often asked whether a glitchy update or a “software patch” that doesn’t stick can support a California lemon law claim. Below, we explain how OTA updates fit into the repair process and what rights California consumers have when digital fixes don’t solve real-world defects.
Why Over-the-Air Updates Aren’t a Cure-All
Modern vehicles rely on complex software to run everything from the infotainment screen to advanced driver-assistance features and battery management. When something goes wrong—a screen freezes, the car won’t shift, the lane-keep system jitters, or the EV suddenly loses range—manufacturers often try an OTA update first. Sometimes that works. But if the underlying issue is hardware-related, or a deeper software conflict, a quick digital patch may only mask symptoms for a while.
When the same issue returns after an update, it’s a sign the root cause may not have been fixed. For example, a braking assist warning that keeps popping up after multiple firmware pushes may indicate a failing sensor or wiring problem, not just a code bug. Likewise, repeated infotainment reboots after “successful” updates can point to module defects or power distribution faults that require in-shop diagnosis and physical parts.
These recurring problems can be frustrating because remote updates don’t always generate the same paper trail as a traditional dealership visit. If your car receives OTA updates that don’t resolve the issue, take screenshots of update notices, note dates and mileage, and describe the symptoms in a log. Then ask your dealer to open a repair order referencing the update and your complaint. That documentation helps show that genuine repair attempts occurred—even if the “fix” arrived through the air.
Your Rights in California When Fixes Don’t Stick
California’s Song-Beverly Consumer Warranty Act (often called the California lemon law) protects buyers and lessees of new vehicles that have defects the manufacturer can’t repair after a reasonable number of attempts under the original warranty. There isn’t a one-size-fits-all number, but California’s “lemon law presumption” provides guidance during the first 18 months or 18,000 miles: for many defects, four or more repair attempts may qualify; for issues likely to cause serious injury or death, two or more attempts may count; and 30 or more total days out of service can also trigger the presumption. Whether or not you fall within the presumption, you may still have rights based on your specific facts.
OTA pushes and remote resets can be part of those “repair attempts” if they are performed or directed by the manufacturer or an authorized dealer and appropriately documented. If your vehicle had to go to the shop for software reflashing or module replacement, the time it stayed there may count toward “days out of service.” Even when your car remains drivable, repeated failures after each software fix can demonstrate that the defect substantially impairs use, value, or safety—especially when it involves braking, steering, charging, stalling, or other critical systems.
If your vehicle qualifies, potential remedies under California law can include a buyback (repurchase), a replacement vehicle, or a monetary settlement sometimes called “cash-and-keep.” The specifics depend on your situation, and there may be a mileage offset and other factors to consider. To protect your options, keep copies of all repair orders, update notices, warranty booklets, and communications with the manufacturer. Report problems promptly, don’t ignore recall or service campaign notices, and request that every attempted fix—remote or in-person—be recorded on a repair order.
