When Over-the-Air Software Updates Break Your New Car

DefectsJune 15, 20266 min read read

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. A detailed guide to this rule is available at /blog/days-out-of-service-florida-lemon-law.


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:

  1. 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.
  2. 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.


The Arbitration Process

Before most Lemon Law cases go to court in Florida, they go through arbitration. If the manufacturer runs a state-certified arbitration program, a consumer generally uses that program first. After that, or if no certified program exists, the case may go to the Florida New Motor Vehicle Arbitration Board, which is administered through the Florida Attorney General's office.

Arbitration is a formal hearing process. It is not as intimidating as a courtroom, but it does require preparation and solid documentation. Many consumers find it helpful to understand what to expect before walking in. Past results do not predict future outcomes.


Attorney Fees Under the Lemon Law

One of the most important features of Florida's Lemon Law is fee shifting. If a consumer prevails, the manufacturer is required to pay the consumer's reasonable attorney fees. This means many consumers can work with a Lemon Law attorney without paying fees out of pocket. If there is no recovery, you owe no attorney fee. Court costs and expenses may apply and are explained in writing before any case begins.


Practical Steps to Take Right Now

If an over-the-air update caused a problem with your new Florida vehicle, here is what many consumers do to protect their rights:

  • Document the update. Note the date it installed, the version number if visible, and exactly what changed in the vehicle's behavior.
  • Report the problem to the dealer promptly. Do not wait. The 24-month rights period is firm.
  • Get everything in writing. Ask for a copy of every repair order and make sure the description of the problem is accurate.
  • Track your days out of service. Write down every date the vehicle was at the dealer and when you got it back.
  • Keep your communication records. Emails, texts, and letters from the manufacturer or dealer can matter later.

The 24-month rights period starts on the date you originally took delivery of the vehicle. Defects that appear late in that window still count, but time matters. If you are concerned about timing, you can learn more at /blog/defect-appears-late-in-rights-period.


Software Is Part of Your Vehicle

Automakers are integrating software more deeply into every system of a modern car, from steering and braking to climate control and charging. That makes over-the-air updates powerful, and it also makes them a real source of defects. Florida's Lemon Law was written to protect consumers from vehicles that do not work as they should. A software nonconformity that substantially impairs use, value, or safety fits squarely within that protection.

If your new vehicle changed for the worse after an update, the law may be on your side.
