@hube2 This actually worked for me! I was able to get all products that have relationship to certain cars:

// Array of car IDs
$cars = [1, 2, 3];
$cars = array_map(function ($car_id) {
    return [
        'key' => 'cars',
        'value' => '"' . $car_id . '"',
        'compare' => 'LIKE',
    ];
}, $cars);
get_posts([
    'numberposts' => -1,
    'post_type' => 'product',
    'meta_query' => [
        'relation' => 'AND',
        [
            'relation' => 'OR',
            ...$cars,
        ],
    ]
]);

Thank you!
