I have had numerous problems with this car, but the latest is the interior door panels on BOTH back doors have come loose preventing the doors from closing. UGH!! There was absolutely nothing that happened that caused the panels to come loose. Made an appointment with the dealer to address, may look for help elsewhere.
An upholstery shop might be able to address the problem.
Do that, it is an old car. No need to pay dealer prices for the repair.
