I am guessing that this was a used vehicle and there was no warranty given by the seller. Florida has no used lemon law vehicle warranty, but this may still be actionable.
When one purchases an item, even if one does not have a specific warranty, it comes with a set of implied warranties. These implied warranties are very ambiguous in law by nature.
An implied warranty of fitness for a particular purpose is a warranty implied by law that if a seller knows or has reason to know of a particular purpose for which some item is being purchased by the buyer, the seller is guaranteeing that the item is fit for that particular purpose. FL 672.316.
An implied warranty of merchantability is a warranty implied by law that goods are reasonably fit for the general purpose for which they are sold. FL 672.316.
Now, both are very subjective and are based on (1) the item's condition at time of purchase, (2) the amount the item was purchased for, (3) how long an item of such nature normally would be expected to last for, and (4) whether or not you waived these warranties by writing.
Someone in your situation may wish to try to argue in Court under such a warranty. If one wins, the Court may order a judgment for repair, although it would be unlikely to void the sale itself.
Best of luck.
