Was stopped at a red light, car had been driving fine, but when the light turned green and I proceeded my car suddenly had reduced power and would not drive more than 40-45 MPH. No lights or anything came on the dash the first time. The second time however a yellow/orange wrench light appeared. I got home and parked for the remainder of the day but then the following day the problem still proceeded and I then let it sit all weekend. The following monday I turned it on to take to the repair shop and the car drove fine that entire day. The next day, tuesday, while driving home from work it happened again only I couldnt go faster than 30mph in a 55 MPH zone. Car was taken back to shop and diagnosed as a failure in the throttle body. During this time of reduced power fans in the trunk space got extremely loud and began sucking in air, as if trying to cool the batteries. Needless to say ford has been no help and I can not get to work as I cannot safely drive my vehicle due to the limp home mode activating and random times. The prior investigation infuriates me to see they extended a wattanty instead of doing recall because now owners like myself are stuck not even being able to get to the dealership because the car is not safe to operate.
Experienced two in-traffic drive-train shut-downs as dangerous as the g.m. Ignition switch malfunctions... Traveling in 60mph-70mph night-time valentine's night freeway traffic on the I-405 in santa ana, ca. In the #3 lane of 5 lanes, the check engine warning light suddenly flashed on - accompanied by the `screech' of the `check gauges' tone - and the drive-train lost all power -- along with the absolutely worthless text "stop safely now". With no power steering, and limited brake booster reserves, I activated the hazard flashers - and thanks to alert and courteous traffic, was able to stop in a "reverse gore-point" between the freeway lanes and an outside transition road. Things could have come out far-worse if overtaking drivers had been inattentive - or we had to cross the path of a big-rig with limited braking- or steering capabilities. As an accident reconstructionist, this is unacceptable. This is the second of our family's fomoco hybrids to experience such in-use drive-train shut-downs that provide the driver with no usable warnings of impending doom - not even "limp-away power" ... The "after-it's-too-late" message-panel might as well display "kiss your a$$ goodbye". The idiot fomoco engineers who decided to "protect" the hybrid battery by "stalling" the vehicle on the freeway obviously never considered what a freeway-speed rear-end impact would do to their precious battery...or to the "replaceable" living occupants of the vehicle.
Just after starting my car and driving down my street at ~5mph, there was a warning symbol (red triangle) and then message saying "stop safely now." the vehicle then lost power steering, and power to the engine. I restarted the car and made it ~100ft and the same thing happened again. This also happened several times previously on the highway traveling ~65mph and with the same message "stop safely now" message appeared and immediately lost all power to steering and the engine. I went to the ford dealership and was told to replace the hybrid coolant pump and blend doors and this fixed the problem for several months until today. I had also just taken the vehicle into the dealership for a recall on the power steering. This loss of power and ability to steer is extremely dangerous! This needs to be recalled!
The SUV lost all power while driving 70mph on the highway...everything went off including the engine. The dashboard LED read pull over immediately.
My car, on 4-5 occasions now, has lost all power while traveling on the freeway at about 80 miles per hour. I called ford because of the electronic throttle body customer satisfaction program and my vehicle does not qualify because of the assembly plant that the car was built at. I can attest that my vehicle is doing the same exact thing that is described in the accounts of the problem with the throttle - without question. I urge you to expand the program that ford is being required to do for this massive (over 1 million vehicle) problem. This appears to me to go beyond a plant issue to an engineering issue with the part itself.
