Ok: The Chysler line uses a pressed in stud and a nut (lug) to hold on wheels. When the stud breakes off which is either from being way overtightened at some point or corroded you can remove the hub and replace one on most applications. If more than that the hub should go. If they just up and broke them all they are stupid. When you have a problem with these you take your time and do everything NOT to break them. They can get so bad that the only way to fix this is to replace them and that can cost some bucks. You would have been stuck anywhere or at any place that had to remove that wheel if they were justifyably stuck/rusted.
Now: Who is at fault with something like that? Stuff happens. Vehicles should be made such that those things don't corrode to that state but I wasn't in charge. Vehicles that get wheels rotated and brakes inspected routinely don't usually have a problem. If it happens to one lug the tech should stop and figure out the risk of breaking more and you should be consulted about the expense. That's a communication problem.
The recall should work out fine. I was worried that if your son (could have been anyone) messed with it than it could raise questions about the cause of the problem or that it was made worse.
A problem with recall and warranty work at dealers is that the pay for those jobs is usually rock bottom as agreed upon by the manufacturer or a warranty company and they don't fare too well with cut rate compensation so they try to get things done as cost effectively as possible. THIS IS THEIR PROBLEM NOT YOURS THE CUSTOMER! If they try to wiggle out of it at your expense that's just bad protocol or YES - a plain rip-off. That needs to be addressed with management or owner's in charge no matter where something like that may happen.
That part is common to any business and how they treat customers. Wish you luck,
