Tank Filler Pipe And Cap problems of the 2009 Hyundai Santa Fe

Incident 1: (10-20-2010) driver side head light was fogging up constantly. Dealer replaced the head light under warranty. Incident 2: (02-22-2011) upon fill-up of the gas tank, just before it was topped off, there was a series of clunking noises. After taking it to the dealership, the gas tank was replaced. Incident 3: (05-01-2011 approx. ) upon removal of the cabin air filter cover, the little plastic parts that are squeezed to remove the cover broke, which wouldn't allow the cover to go back on. The dealer replaced the part and I have not yet replaced the filter yet. Incident 4: (11-12-2011) driving 60 mph down the highway, I heard a loud banging noise coming from the engine compartment. As I was pulling over to check out the situation, the car lost power steering and air conditioning! my serpentine belt broke! after it was towed, the dealer replaced it, along with belt tensioner and idler pulley! incident 5: (07-30-2012) I was coming up to a stop light and upon deceleration, the check engine light and esc off light came on. After coming to a complete stop, the rpm gage showed 1100 rpm and it felt like the vehicle wanted to move as if I was pressing the accelerator. When I did try to accelerate, there was no power to accelerate ( the engine was still running, etc, but when I pressed the accelerator, I could only move a few miles per hour. ) I pulled over and shut the vehicle off for a few minutes. I started it back up and the check engine light remained on, and I gained acceleration power. I took the vehicle to the dealership. They determined I had a faulty throttle position sensor as well as brake light switch and both were replaced by the dealer. [current mileage on vehicle after all incidents: 48,897].
