Quick Answer: Yes. A vehicle may qualify as a lemon under California’s Song-Beverly Consumer Warranty Act because of recurring software or electronic problems. Software now controls braking systems, cameras, climate, charging, steering assistance, battery management, and driver profiles — and a manufacturer cannot avoid lemon law responsibility merely by describing a recurring warranty defect as “just a software issue.” The defect must substantially impair the vehicle’s use, value, or safety and remain unfixed after a reasonable number of repair attempts.
Key Takeaways
- Software-controlled systems — cameras, charging, climate, braking warnings, profiles — are covered when the defect is under warranty and substantially impairs use, value, or safety.
- One 2020 Jaguar I-PACE case involved software-related repairs to at least nine control systems, plus recurring camera, profile, heating, charging, and wiper problems, before settling.
- Repeated software updates that do not hold are evidence that earlier repairs failed.
- “No update available yet” does not eliminate the consumer’s rights — it may strengthen the claim.
Modern vehicles rely on software for far more than entertainment. Software may control braking systems, cameras, climate functions, charging, steering assistance, driver profiles, battery operation, safety sensors, and numerous other vehicle functions.
A manufacturer cannot necessarily avoid lemon law responsibility merely by describing a recurring defect as a software issue.
Modern Vehicles Are Computers on Wheels
Today’s vehicles contain multiple control modules that communicate with each other. Software may affect:
- Starting and shutting down
- Battery management
- Charging
- Backup cameras
- Parking sensors
- Climate controls
- Navigation
- Driver profiles
- Windshield wipers
- Steering systems
- Brake systems
- Infotainment displays
When software does not operate correctly, the vehicle may lose one feature or multiple systems at once.
A Jaguar I-PACE Case With Repeated Software Repairs
A California lemon law case involving a 2020 Jaguar I-PACE included numerous module updates, resets, and reprogramming procedures. The dealership performed software-related repairs involving:
- The infotainment master controller
- The transmission control system
- The image-processing module
- The battery-energy control module
- The climate-control system
- The occupant-monitoring module
- The body-control module
- The anti-lock braking system
- The power-steering control module
The vehicle’s recurring problems included backup-camera failures, disappearing driver profiles, heating failures, charging-setting problems, and automatic-wiper malfunctions. The case later settled.
The Backup Camera Required Multiple Software Repairs
The rearview camera intermittently failed to appear in reverse. The dealership initially could not reproduce the concern. It later performed an infotainment controller update and transmission-related programming.
At another visit, the dealership verified the camera failure and found that the image-processing module required a software update.
Repeated software updates may be evidence that the first repair did not permanently correct the problem.
A Software Update Did Not Fix Disappearing Driver Profiles
The vehicle repeatedly deleted saved driver profiles. The dealership updated the occupant-monitoring module. When the issue returned, the dealership found a memory fault and replaced the module. The profile problem later returned again, requiring another module replacement and programming.
This demonstrates that a problem initially treated as software-related may ultimately involve defective hardware, memory, or a control module.
When Does a Software Defect Become a Lemon Law Issue?
A software problem may support a claim when:
- It is covered by the manufacturer’s warranty
- It substantially impairs use, value, or safety
- The manufacturer has been given reasonable repair opportunities
- The problem continues or repeatedly returns
- Updates or resets do not permanently correct it
The feature affected matters. A temporary issue with a minor display preference may be viewed differently from a defect involving braking warnings, loss of propulsion, a backup camera, charging, steering, or climate control.
What if the Dealership Says No Repair Is Available Yet?
Sometimes a dealership states that no update or repair is currently available. That does not necessarily eliminate the consumer’s rights. The manufacturer’s inability to provide a repair may strengthen the argument that the vehicle could not be conformed to warranty within a reasonable period.
Consumers should ask that the repair order state:
- The defect was reported
- The dealership verified it, when applicable
- No repair or update was available
- The manufacturer was contacted
- The owner was advised to wait for future software
What if an Update Temporarily Fixes the Problem?
Return to the dealership if the problem reappears. Make sure the repair order identifies:
- The prior update
- The date the problem returned
- Whether the failure is identical
- Whether the feature worked temporarily
- Any related error messages
A sequence of temporary fixes may demonstrate that the manufacturer had multiple opportunities but did not achieve a lasting repair.
Frequently Asked Questions
Does California lemon law cover software and infotainment defects?
Yes, when the defect is covered by the manufacturer’s warranty and substantially impairs the vehicle’s use, value, or safety. The Song-Beverly Consumer Warranty Act does not distinguish between mechanical and software defects.
Do over-the-air or dealership software updates count as repair attempts?
A warranty visit where the dealership attempts to fix a reported defect — including through a software update, reset, or reprogramming — may count as a repair opportunity. How courts treat remotely pushed over-the-air updates that occur without presenting the vehicle to a repair facility is a developing area, which is one more reason to keep reporting the defect to an authorized dealership and to document each visit on a repair order.
What if the manufacturer says a fix is coming in a future update?
Waiting indefinitely is not required. If no repair is available, ask the dealership to document that on the repair order. The absence of an available repair may support the argument that the vehicle could not be conformed to warranty within a reasonable time.
A note on deadlines: California lemon law claims are subject to filing deadlines. Procedural changes that took effect in 2025 (AB 1755 and SB 26) added pre-suit notice requirements and filing windows — generally one year after the express warranty expires and no more than six years after original delivery — for manufacturers that opted into the new process. Whether those rules apply to your claim depends on your manufacturer’s election, so acting promptly is the safest course.
Disclaimer: Prior results do not guarantee a similar outcome. Every California lemon law claim depends on its own facts, repair history, and warranty coverage.
