While driving at normal speeds, the transmission hesitates and pops when shifting into 4th gear. The vehicle slows down unexpectedly before shifting and will suddenly downshift without warning. This causes abrupt deceleration and creates a safety concern, especially at highway speeds. The issue occurs intermittently and without driver input. Even when I’m in normal gears it will downshift and cause me to slow and lose control even when I am not breaking. It occurs at just 35 mph- highway speeds.

I have been driving since 1964 and have never experienced a total loss of all braking power in any .vehicle in my life until last Sunday. I exited from the church parking lot and pulled out onto the main drive headed home. As I approached a signal light at a "T" intersection traveling across the top of the "T" right to left, the light turned yellow so I applied my brakes to slow down, only to find that the brake pedal traveled all the way to the floor without any hesitation and the car continued on its path without slowing at all. I immediately released my foot and permitted the pedal to rise to its normal position and I pressed on it again, only to get the exact same result. I immediately down shifted to first gear and pushed down on the emergency brake pedal which slowed the car to a stop before I entered the intersection. I shifted into park and tried pressing on the brake pedal to "pump up the braking system" and got some relief, however as soon as the light change and I put the car back in drive, all resistance from the brake pedal system quit and I was back in free fall. I managed to get home using manual shifting and emergency brake assistance. The braking system never returned to any form of even trying to control the forward momentum of the vehicle. I checked the internet to find that there were pages of people entering reports of similar issues with their F150's and yet there was no report of any recall or safety issues reported. Now I may be wrong but I thought I was told back in drivers ed back 1965 the the braking system in cars had an X configuration so if something happened to the brake lines that feed the front right to rear left, that the front left and rear right wheels would still be there to get to you stopped. Well I can assure you that when the little 18" rubber hose that connects the metal hydraulic line to the front right disk caliber on my car split open, NOTHING worked not even a warning light came on until no brake fluid existed.

After morning startup, vehicle stumbled, hesitated on acceleration into traffic. Vehicle stalled after approximately driving 1 mile. Would re-start, only idle, then stall when put into drive and attempted to re-enter traffic. I had towed to closest ford dealership for warranty repairs. My vehicle was returned over two weeks later. The service invoice outlined that the low pressure fuel pump was found bad, shorted and connecting plug to harness melted. They replaced fuel pump and repaired harness plug. Vehicle was not fixed. Over the two week period the vehicle was at the dealership, the fuel pump driver, body control module, and last the engine control module was replaced to repair the problem. My major concern is the melted fuel pump plug. I would think there would be adequate fusible link protection to keep this kind of problem from happening especially when affecting an in tank fuel pump. This might lead to fuel fires and also accidents due to loss of power from the engine. I was fortunate to be able to safely get my vehicle on the road shoulder, and then onto a side street with minimal traffic. Another issue is that one device failure creating failures in multiple vehicle control systems that would cost the consumer thousands of dollars out of warranty to repair. I was told that a ford field engineer was sent to assist the dealership, after his visit, the ECM was replaced which made the vehicle functional again. Adequate overcurrent protection on the fuel pump should have prevented damaging the other critical parts. Ford has put a lot of these vehicles on the road with the fuel efficiency new engineering as a major marketing tool. I fear the vehicle may have been rushed to production with inherent flaws that could be a danger to owners and the public.
