Your Car Got an Update Last Night. Now Something Is Wrong.
You wake up, get in your car, and something feels off. The infotainment screen freezes. The adaptive cruise control refuses to engage. The battery range estimate dropped by 40 miles. You did not do anything. But your car downloaded an over-the-air software update overnight, and now it is not working the way it should.
This is happening more often. Modern vehicles, especially electric and hybrid models, receive software updates the same way your phone does. Automakers push these updates to fix bugs, add features, or adjust performance. Most of the time, things go smoothly. But sometimes an update introduces a new problem, or makes an existing one worse.
If that happens to your new Florida vehicle, Florida's Lemon Law, Chapter 681 of the Florida Statutes, may give you important rights.
What Counts as a Covered Vehicle
Florida's Lemon Law covers new motor vehicles and demonstrator vehicles that were sold or leased in Florida. It does not cover used cars. The vehicle must have been originally delivered to the consumer, and the defect must show up within the Lemon Law rights period, which runs for 24 months from the date of that original delivery.
If you leased a brand-new vehicle or bought a demonstrator model, you may also qualify. You can read more about demonstrator coverage at /blog/demonstrator-vehicle-lemon-law.
Does a Software Problem Count as a Defect?
This is a fair question. Some people assume the Lemon Law only covers mechanical parts, like a bad transmission or a leaking engine. But the statute does not limit coverage to hardware. What matters is whether the problem is a nonconformity and whether it substantially impairs the use, value, or safety of the vehicle.
A software defect can absolutely meet that standard. Consider these examples:
- An update disables a safety feature, such as automatic emergency braking or lane-keep assist
- The update causes the vehicle to lose power unexpectedly while driving
- Infotainment and navigation become so unstable that the vehicle is distracting or unusable
- A battery management software change significantly reduces driving range on an electric vehicle
- The update triggers warning lights that prevent normal operation
If the problem makes the vehicle harder to use, less valuable, or less safe, it does not matter whether the root cause is a software file or a physical component. The law looks at the impact on the vehicle, not the source of the problem.

The Repair Attempt Rule
Once a nonconformity appears, the manufacturer gets a reasonable number of chances to fix it. Under Florida's Lemon Law, after three repair attempts for the same problem, the consumer has the right to send the manufacturer a written notice called a Motor Vehicle Defect Notification. This notice gives the manufacturer one final opportunity to repair the defect.
With software problems, repair attempts can look a little different. A dealer may push a patch, roll back the update, or run a diagnostic without making any physical repair. That still counts as a repair attempt if the consumer brought the vehicle in and the dealer tried to address the problem. Keep records of every visit, every work order, and every description of what was done.
Days Out of Service
There is a second path that does not depend on counting repair attempts. If your vehicle has been out of service for 30 or more cumulative days due to repair, that can also qualify you to pursue a Lemon Law claim, after written notice and an opportunity for the manufacturer to inspect and repair the vehicle.
Software defects sometimes drag out. A dealer may hold a car waiting for an official patch from the manufacturer. Those days in the shop count. Save every loaner car agreement, every service receipt, and every communication about why the vehicle was not available to you.

What Remedies Does the Law Allow?
If a vehicle qualifies under Florida's Lemon Law, the statute allows the consumer to seek one of two remedies:
- A refund of the purchase price, including collateral charges and finance charges, minus a statutory offset calculated based on the consumer's use of the vehicle before the defect was first reported.
- A replacement vehicle that is comparable to the original.
The manufacturer chooses which remedy to offer, though consumers have input in the process. The statutory offset for use means the refund reflects actual miles driven before the problem arose, not the entire mileage on the car.
