Try my code below to see if it works. Let me know what errors you get

In your <form> just place a hidden textbox with a name of id like so:

<form>
    <input type="hidden" name="id">
</form>

And then in your PHP do this:

<?php

$host = "localhost";
$user = "db_user";
$pass = "db_pass";
$db = "db_name";
$charset = 'utf8mb4';

$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
try {
    $opt = [ PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC, PDO::ATTR_EMULATE_PREPARES => false, ];
    $connection = new PDO($dsn, $user, $pass, $opt);

    if (isset($_POST['placa'])) {
        //I don't see a reason to have all of those isset...just make it so that there's one field that 
        //is absolutely required and cannot be left empty and work from there.

        $statement = $connection->prepare("INSERT INTO vehiculo (id, placa, serialcarroria, serialchasis, serialmotor, marca, modelo, year, color, tipo, uso, nropuestos, nroejes, capcarga, servicio)
        VALUES (:id, :placa, :serialcarroria, :serialchasis, :serialmotor, :marca, :modelo, :year, :color, :tipo, :uso, :nropuestos, :nroejes, :capcarga, :servicio)");
        $statement->bindParam(':id', $id);
        $statement->bindParam(':placa', $placa);
        $statement->bindParam(':serialcarroria', $serialcarroria);
        $statement->bindParam(':serialchasis', $serialchasis);
        $statement->bindParam(':serialmotor', $serialmotor);
        $statement->bindParam(':marca', $marca);
        $statement->bindParam(':modelo', $modelo);
        $statement->bindParam(':year', $year);
        $statement->bindParam(':color', $color);
        $statement->bindParam(':tipo', $tipo);
        $statement->bindParam(':uso', $uso);
        $statement->bindParam(':nropuestos', $nropuestos);
        $statement->bindParam(':nroejes', $nroejes);
        $statement->bindParam(':capcarga', $capcarga);
        $statement->bindParam(':servicio', $servicio);

        $id = $_POST['id'];
        $placa = $_POST['placa'];
        $serialcarroria = $_POST['serialcarroria'];
        $serialchasis = $_POST['serialchasis'];
        $serialmotor = $_POST['serialmotor'];
        $marca = $_POST['marca'];
        $modelo = $_POST['modelo'];
        $year = $_POST['year'];
        $color = $_POST['color'];
        $tipo = $_POST['tipo'];
        $uso = $_POST['uso'];
        $nropuestos = $_POST['nropuestos'];
        $nroejes = $_POST['nroejes'];
        $capcarga = $_POST['capcarga'];
        $servicio = $_POST['servicio'];

        if ($statement->execute()) {
            echo 'data inserted successfully';
        } else {
            echo 'Sorry, there has been a problem inserting your details..';
        }
    }
}
catch(PDOException $e) {
    echo "Error: " . $e->getMessage();
}

$connection = null;
