Engine Belts And Pulleys problems of the 2006 Ford Escape

I own a 2006 Ford Escape XLT with 100,000 miles. 90% highway miles, well maintained with dealer or independent mechanic. Have all paper work. "my biggest worry is the stalling for no reason and an accident happening and this should be a recall issue". Jan. 2015 I had a intake and valve oil leak that was fixed 3 times, Jan, Feb and March. When I took it to the dealer in March, I mentioned that my vehicle had stalled in my driveway after a 30 minute highway drive from work. They put it on the computer and said there was no code for a stall. Dealer said Ford sent them notice describing my same issue but couldn't confirm it was the torque converter. April 10th 2015 I was out of extended warranty. The stalling happened again late April, took to dealer again. Dealer said no codes again. Took straight to uncle after leaving dealer for him to look at and couldn't get the vehicle to stall after a week of having it. I've read online forums of people replacing transmission multiple times for torque converter and other issues within the transmission. Also, after 3 deer ran out in front of me 2 years ago, repairs done to physical damage and passenger seatbelt replaced twice during repairs, passenger seatbelt and airbag lights come on and seatbelt alert beeps while driving even know the passenger has the seatbelt on. I have to park, shut down, buckle seatbelt and then start again and this worked except for one time I had to repeat this a second time. Dealer said there was no codes for airbags or seat belts. Ford has not been notified yet. Also, when I bought the vehicle brand new I had the underbody sprayed but the rear wheel wells are rusting from underneath to outer body and rusting under front doors too.

Loud noise while starting vehicle in cold weather. Idler pulley was shredding the serpentine belt and pulley was overheating. Dealer replaced under warranty.
