| Vehicle Speed Control problems |
I was driving on the highway at a speed of approximately 70 miles per hour when the Bronco driver screen gave multiple warning notices and at the same time, the accelerator would not react. Steering power was fine. I was in the second from far left lane on a six lane highway and losing speed quickly. I was able to move to the right and drift to the side of the road without incident. Once stopped, I turned the ignition off and waited a few seconds and then turned it back on again. The error messages all cleared and the Bronco accelerator reacted appropriately. I drove it straight to the dealership for inspection. They found the 210 connector was not making a good connection. They cleaned it and added electric grease and reconnected. Everything cleared and the connection was deemed good. I have not worked in the Bronco engine compartment or had work done that would have resulted in loosening the 210 connector. My understanding from the shop is that corrosion caused this connector to loosen.
Multiple times the engine has failed to respond to the accelerator pedal when engaged from a cold stop. The delayed response has happened several times while attempting to merge into moving traffic so even a 1 second delay is both dangerous and scary from a driver perspective. The vehicle was taken in for service recently and no problems were identified after mechanic testing. However, I wonder if this problem is related to the ongoing investigation of defective valves in the 2. 7l ecoboost engine.
1. Vehicle issue. -at approximately 2k miles while driving through severe weather in the rocky mountains my new Bronco lost all electronic driving systems that controlled driving modes including 4 wheel drive modes(goat) along with safety systems such as traction control, sensor systems, and cruise control. I was forced to drive through a white out in rocky mountains with 2 wheel drive due to the electronic goat modes failing. This was a dangerous situation as the systems I was relying on failed me when I needed them most. These systems failed off and on for the next three months before mysteriously subsiding. 2. Attempts to resolve. - took vehicle to Ford dealer to identify issue and they said there was no record of these failures in the code system which is extremely concerning. If I had gone off the road and injured myself and or died Ford would attempt to say there was no electronic failure when in fact there was a significant electronic failure of all traction systems. Fortunately I took video and photo evidence of the electronic failures. Alarmingly, these failures are not being recorded within the vehicle.
