They need to get rid of the rear seat folding latches and make something more secure. The quarter window break-ins should have prompted that re-design after the first year. Unsecure latches exist in hatchbacks and SUVs since the cargo area is exposed due to the car design, but a sedan should have a secure trunk/cargo area. Even in the 90's, sedans had a latch in the trunk to release or to stick your key in the rear deck to drop the seats (but I guess that wouldn't work since we don't have a key...)
If you're just worried about security, have those windows covered with 3m security film. Thieves won't be able to break through the window. It will still break, but just won't be knocked out.
