Wiring problems of the 2012 Ford Fiesta

Due to moisture and debris getting into the fuse box under the hood of the vehicle, the relay for the low beam headlights has corroded and one of the pins is corroded into the fuse box. This has left me without the use of my low beam headlights. I have contacted Ford us and was told there was nothing they could do. The repair for this issue will cost approximately $1500 from the dealer for parts and labor without any solution to the sealing of the fuse box. When I called Ford us customer service and requested to speak with a supervisor regarding the issue, they hung up on my. This problem has been ongoing with 2011-2013 Ford Fiestas. This is a safety concern as the headlights just quiet working. This fuse box also controls various other critical components of the vehicle and is tied into the main wiring harness. The corrosion issues can also affect those systems as well.

The vehicle had an abnormal idle while at a stop, and would sometimes stall. Upon acceleration the vehicle would hesitate and jerk forward. I took the vehicle to the dealership to rectify the issue. I was told that the mechanic cleared the code for the check engine light, but the internal wiring harness needed to be replaced, on a car that was a little over 2 years old. The internal wiring harness was not covered under any type of warranty. The repair was completed at a cost to me of $245. 99. Less than 2 months later, the vehicle was having the same issues, abnormal idle, stalling, and hesitant and jerky accelerating. Again, I took the car back to the dealership for repair. This time the dealership replaced the transmission and clutch front seals, input seals, and axles seals, changed transmission fluid, added 2 quarts of transmission dual clutch transmission fluid. This repair was covered under the Ford 5 year, 60,000 mile power train warranty. About 5 weeks later I was still having the same issues, abnormal idle, hesitant and jerky acceleration. Again, I took my car to the dealership. This time I was told that the throttle body was bad and needed to be replaced. With no choice, I need to get to work, I told them to go ahead with the repair which once again was not covered under any type of warranty. The total for this repair cost me $720. 26. In less than 3 years I have had to go to the dealership for major repairs 3 times and spent just under $1,000, plus the inconvenience of rental cars, days off of work, and the general annoyance of knowing my new vehicle has major mechanical issues.
