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!

I have a 2008 mercury mariner hybrid 4 wheel drive. On occasion the steering will loose power assist while turning. The loss of power lasts for a few seconds before the power assist returns. This problem is dangerous as I have to compensate for the loss of steering assist by turning the steering wheel harder, then when the power assist returns the vehicle turns more than I want because the wheel is easy to turn as I am applying a lot of pressure to the steering wheel. The dealer and ford has not been able to determine the problem or suggest a fix.
