Stop safely now chimes and displayed on dash followed by no acceleration until vehicle stalls and stops.starts right back up but continues to happen especially in la rush hour traffic. Very dangerous! Had recall work done on the mecs 3yrs ago but problem has continued. This happens while in motion on the 110 freeway in downtown los angleles, ca. Could be the electric throttle body or rear actuator. Or any other component that works with the electric motor and battery.

Experienced the second of two in-traffic drive-train shut-downs as dangerous as the g.m. Ignition switch malfunctions (see odi#: 10683675) our initial stopping place - in a "reverse gore-point" between the n/b freeway lanes of the I-405 freeway in santa ana, ca and an outside transition road was unsafe in the full-darkness of a non-illuminated high-speed intersection; with traffic zooming by on both sides, with the flashers still active, I res-started the engine -- all dash warnings cycled on then off normally; on a distinct up-grade, I revv'd the engine against the service brakes, and watched for a suitable gap in traffic over-taking us on our right side. Seeing such a gap, I released the service brakes and accelerated to 30 MPH towards the outer shoulder...but only made it part-way across the 2 lanes when the second shut-down occurred...the same "check engine" light...the same squealing enunciator tone... The same worthless "stop safely now" message and again, thanks to courteous and alert over-taking drivers, I was able to coast to a relatively broad shoulder section beside a `disappearing' right travel lane. It was now 7:55pm. We were on our cell phone to the aaa when a highway patrol officer stopped behind us to check our situation, and provide additional protection until a tow-truck could arrive on-scene. 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.

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.

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!

Had the throttle body fixed once two months ago because I was going 45, my SUV. Hazard light came on and it said to slow down and pull over safely. Then it has happened three more times since I got it fixed, my SUV is in the shop again, I paid 845 last time and I still have $15,000 left to pay on my car. I can't afford to keep paying to get this fixed, let alone the safety issue.the lady two times it happened I had my baby in the car on the freeway and I was in the middle lane and it was raining... It was frightening.

My 2008 mercury mariner hybrid has a dangerous high speed stall condition. It is very serious and puts the vehicle and occupants in a situation that causes a very high risk of a crash. This said, my vehicle is not covered in the current recall? Why not?

A "stop safely now" warning message came on when I was driving on the freeway at 60 miles per hour. The car immediately lost power and became difficult to steer. I pulled over to the right shoulder as safely and quickly as possible. This has occurred multiple times.
