Salt Air Is Tough on New Cars
Florida's coastline is beautiful. It is also hard on vehicles. Salt air, humidity, and brackish water can accelerate metal corrosion far faster than you might expect inland.
When rust or corrosion shows up on a brand-new car, many owners assume it is just bad luck or normal wear. In some cases, though, premature corrosion points to a defect in materials or workmanship. That is when it is worth asking a serious question: does this situation fall under a warranty claim, Florida's Lemon Law, or both?
What Counts as "Premature" Corrosion?
Not all rust on a vehicle is a defect. Surface rust on brake rotors after a rainy week, for example, is normal. Premature corrosion is different.
Premature corrosion generally means rust, pitting, or structural deterioration that appears much earlier than a reasonable person would expect on a properly manufactured new vehicle. Common examples seen on coastal Florida cars include:
- Rust bleeding through paint on door panels or quarter panels within the first year or two
- Corrosion forming around wheel wells, undercarriage components, or exhaust hangers on a near-new vehicle
- Blistering or bubbling paint caused by rust forming beneath the surface
- Structural or frame corrosion that affects vehicle integrity
When corrosion appears this early on a new car, it often signals a failure in rust-proofing, coating, primer, galvanizing, or the base metal itself.
Start With the Manufacturer's Warranty
Most new vehicles sold in Florida come with a corrosion or perforation warranty that lasts several years, sometimes longer than the basic bumper-to-bumper coverage. The length and terms vary by manufacturer.
If your new car shows premature corrosion, the first step for many consumers is to bring it to the dealership and open a warranty claim. Document everything. Take clear photos before you go. Get the repair order in writing. Keep copies of all paperwork.
If the dealer accepts the claim and repairs the corrosion properly, that may resolve the issue. But what happens when the dealer says the rust is caused by your environment and refuses to cover it? Or what if they attempt a repair that does not hold, and the corrosion returns?
That is where Florida's Lemon Law may enter the picture.
Florida's Lemon Law and Corrosion Defects
Florida's Lemon Law, Chapter 681 of the Florida Statutes, covers new and demonstrator motor vehicles that are sold or leased in Florida. Used vehicles are not covered under the Lemon Law.
For corrosion to potentially qualify under the Lemon Law, a few key standards must be met.
The defect must substantially impair use, value, or safety. Under the statute, a qualifying defect is called a "nonconformity." It must substantially impair the use, value, or safety of the vehicle. Cosmetic surface rust on a trim piece may not meet this standard. But corrosion that affects structural components, compromises safety, or significantly reduces the vehicle's resale value could qualify. Each situation is different.
The problem must occur within the Lemon Law rights period. The statute provides a rights period of 24 months from the date of original delivery of the vehicle to the consumer. Corrosion that surfaces after this window has closed generally falls outside Lemon Law protection, though other remedies may still exist.
The manufacturer must have a reasonable opportunity to repair it. Under the statute, after three repair attempts for the same nonconformity, many consumers send the manufacturer a written notice called a Motor Vehicle Defect Notification. This gives the manufacturer one final attempt to fix the problem. Alternatively, if the vehicle has been out of service for 30 or more cumulative days due to repair attempts, that can also be a qualifying trigger, again after written notice and an opportunity to inspect and repair.
The Lemon Law Process: What Happens Next
If the final repair attempt fails to resolve the problem, the Lemon Law provides a path forward.
Most manufacturers operate arbitration programs. If the manufacturer's program is certified under Florida law, consumers generally go through that program first. After that, or if no certified program exists, consumers may bring their case before the Florida New Motor Vehicle Arbitration Board, which operates through the Florida Attorney General's office.
If a consumer prevails, the statute allows for a refund or a replacement vehicle. A refund includes the original purchase price plus collateral charges and finance charges, minus a statutory offset that accounts for the consumer's use of the vehicle before the problem arose. A replacement vehicle is another option under the statute.
One detail that matters to many consumers: if you prevail, the manufacturer is required to pay your reasonable attorney fees under the statute's fee-shifting provision. Many Lemon Law attorneys handle these cases on that basis. 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.
Past results do not predict future outcomes.
