Front Suspension Control Arm problems of the 2005 Hyundai Sonata

While changing my oil on the weekend, I noticed severe corrosion failures with the front subframe on the right side of my car. (see attached photos). One area was in front of the lower control arm and another area is behind the control arm. It looks like the subframe will fail at any moment and the control arm would be free to move anywhere. This would significantly affect control of the vehicle and be a serious safety concern. I see this part has already had a recall for 2001 to 2004 Hyundai Sonatas which is the same body and frame style as the 2005 vehicle. Recall #09v124000.

I took my car to my mechanic to change oil on 1/9/2018 and he discovered a big hole (bigger than the fist-size) on the right front of the subframe underneath the car due to rusting and severe corrosion (please see the attached picture for more details). The mechanic told me that this is a serious safety issue, which is not supposed to happen. He strongly recommended me to go to the dealer and have this fixed as soon as possible. Right after that, I called Hyundai customer service and they told me that my car doesn't have a warranty and it is not under recall based on the VIN, so they will not do anything about it. I got the same answer from the dealer at Hyundai davis in NJ. I searched online and found 2 recalls issued by Hyundai for the same problem. One started in 2009 with the NHTSA recall id # 09v124000 (including 1999-2004 Hyundai Sonata) and another one in 2013 with NHTSA campaign # 13v354000 (including 2006-2010 Sonata). However, Hyundai customer services can't provide any explanations why 2005 Sonata is not included in the two recalls. According to the news online, �the recall, limited to America's so-called "salt belt" states, is centered around potentially excessive corrosion of the front sub-frame due to winter road salt applications. If unnoticed, the lower control arm may separate from its mount. � �road salt and water can enter portions of the rear crossmember, leading to corrosion of the crossmember steel. This may lead to detachment of one of the rear control arms. Control arm separation may suddenly change the rear wheel alignment, affecting the handling of the vehicle, increasing the risk of a crash. � it is not safe for me to drive the car, however, currently, I still have to drive the car on highway to work on a daily basis since this is the only car I have.

According to mechanic the upper control arm rear passenger side is rusted and detached.
