Headlights problems of the 2004 Ford F-150

To begin with I had to have all 4 windows repaired. The mechanism that raises and lowers the windows broke. Since this was bought as a used vehicle, there was no warranty. So I pd. $150. To $175. 00 each. Was told Ford knew of this problem but since it wasn't a "safety factor" no recall was issued. I feel like this is quite unfair to the consumer. We purchase a vehicle that has a good reputation and then are told that this expense is our baby to take care of. I feel like this was very unfair to this consumer. I have purchased Fords for years with no complaints until now. Also, the headlights developed a leak and filled with water thus shorting out my right headlight,and is slowly doing the same to the left one. I have been told that just the burned out bulbs cannot be replaced,that the whole assembly had to be replaced and this is at a cost of approx. $175 to $200. Per assembly. This is outrageous. Also,there is a problem with what used to be "points & plugs" which are now a "coil" assembly. This problem developed approx. 6 months ago. According to the readouts I have gotten, the #1 plug is misfiring approx. Every ,1000 revolutions which causes a miss in the engine and was very alarming to me since I was on the highway about 200-250 miles from home, traveling by myself. So, another expense is looming. I realize there are expenses to owning a vehicle. I do not expect to not have any problems or repairs with my vehicle,but I did not anticipate this many. Nor did I expect the cost of the repair parts alone to be so outrageous. I am on a fixed income and had I anticipated these problems I wouldn't​ have made this purchase. I truly love my truck, but is there anyway these other repairs can be done for a lesser amt? I've already pd. To replace motor &rotors in all 4 windows. Any help you can give me would be greatly appreciated. Thank you. Martha greenwell.
