Power Steering Pump problems of the 2010 Ford F-150

Steering gets easy and hard when it's warm (75+) not power steering pump. Rpms have no impact. Not steering shaft, power steering pump, power steering fluid, ball joints steering rack. . . Mechanics are at a loss. About 33,000 miles.

I live in a metropolitan area where there is always a high volume of traffic and losing power of a vehicle is a dangerous situation. Driving in 5:00 rush hour traffic and accelerating from a red light when my Ford truck entered into a "limp home" mode (wrench icon and oil lamp appeared) it stalled out. I was able to coast into a parking lot even though I had no power steering or brakes. Eventually, I was able to start my vehicle. My truck drove fine but now and then had a hesitation to start. About a week later, it stalled again; this time it did not start. I was a block from my office and we pushed it back. I had it towed to a local shop and was told it was the fuel pump. I work in outside sales and had to have it replaced $700. The truck drove ok for about a month, but still hesitated on starting. In June, once again it stalled. I took it back to the shop and they could find nothing wrong. July 9th, I was driving about 55 mph when I came to a signal light and stopped. The light turned green, I begin my left hand turn and the truck stalled. I had it towed to Ford dealer. They are saying that now it is the fuel pump battery junction box, another $2500 and it will take after labor day before I get my truck back because there are no parts available!!! rent a car for 2 months on top of that!!!.

For no apparent reason power steering pump made laboring noise when wheel turned. Observed leaking power steering hose. Diagnosed by Ford dealer as such and could not repair due to a national backorder of the needed hose and neither Ford or dealer could say when the part would be available. Vehicle is under extended warranty however the third party warranty company wouldn't warrant repair using a locally fabricated hose because fabricator would not warrant part for 12 months therefore I am faced with paying for entire cost of repair by dealer. Neither dealer nor Ford would own up to paying for the repair or rental of a car while my truck is in shop.

Engine stalls at low speeds causing loss of steering and braking. There was no check engine light or error code when this first occurred. After the engine had stalled for about 32-35 times, the check engine light finally came on. I took the truck to a local mechanic shop to read the code which indicated that the evap system was blocked. My dealer determined that a solenoid in the fuel evap. System had failed. As a result the fuel tank was collapsed by vacuum because there was no secondary tank vent. This is dangerous! there should be a secondary vent or a pressure/vacuum sensor to prevent the tank from being collapsed. Note: the tank was collapsed so much so, as to damage the pump/level sending unit assembly.
