Re: "Stop Safely Now"
Gotcha. Thank you for that. I'd heard the TBBDA could cause the SSN, but was sceptical just based on my experience, which mirrored yours. I too saw a wrench light at one point, noticed the decreased MPG figures, replaced the actuator and all was well afterward.

Re: "Stop Safely Now"
Hate to be the newb... and in this thread to top it off. Experienced the ssn first at 170k. Was clearly mecs after testing via the "grab the motor housing, twist, and listen for rpm change" car has worked flawlessly since that time and now has 185k on it. Now it has a ssn message is accompanied by symptoms quite different than any I've been able to find. I will replace the relays tomorrow and plan on pulling the battery to inspect connections howevwr I do not expect to find anything there.
Vehicle shut down while doing 55mph, pulled to side of road, cycled key, etc...
Vehicle starts fine. Idles smoothly up to 2k rpm. If accelerator is depressed rpms do not change until it seems the engine becomes flooded and is accompanied by fuel smoke from tailpipe and ssn/shutdown almost immediately. If vehicle is allowed to idle, the idle will dip down, then correct itself at which point smoke comes from tailpipe. It will do this a few times before the ssn message appears and shuts down. I was ablw to pull the vehicle onto my trailer on battery power but that required one key cycle as the battery did shut down after traveling a short distance. I was able to unload and pull in garage after a couple of key cycles. I replaced the trottle body after checking tsbs and taking into consideration the symptoms. Waste of time possibly... dtcs aee p1000, p1a0c, and p1a10. The onlyn possibly related item, wife ran it out of gas 1 day before problem appeared. I did replace the fuel filter before the throttle body to no avail. I really do not want to take it to the dealer as I'm sure they will be as confused as me.

Re: "Stop Safely Now"
Mine is the 2008 FEH. Has anyone with this year or later gotten their harness replaced for free, or was this problem not even an issue with 2008+ models?

Re: "Stop Safely Now"
Update: Replaced all 4 relays to no avail. After SSN is displayed and vehicle shuts down, cooling pump runs momentarily and shuts off. Once that happens you can hear a strange whine from the throttle body motor. I can touch the electrical connector and cause the pitch of the whine to change... This is with the new throttle body from Ford.

Re: "Stop Safely Now"
Just from code P1A0C it sounds like some reprogramming of the PCM is necessary, requiring a trip to the dealer. Found the info below online and may have been superceded by now, but sure sounds like more than just a simple throttle body replacement should be done. Please let us know what you find!

RED TRIANGLE ON AND STOP SAFELY NOW MESSAGE - DTC P1A0C
Publication Date: September 18, 2009
FORD: 2005-2008 Escape Hybrid
MERCURY: 2006-2008 Mariner Hybrid
ISSUE:
Some 2005-2008 Escape Hybrid and 2006-2008 Mariner Hybrid vehicles may exhibit an intermittent Red Triangle on and Stop Safely Now message displayed on the message center, accompanied by a sudden RPM loss/no start with a diagnostic trouble code (DTC) P1A0C. Vehicles may exhibit this symptom on the first start of the morning or after an extended idle. The symptom will clear on the next key cycle.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
Using the Integrated Diagnostic System (IDS) scan tool:
Access and monitor the LOS_STRT parameter identification (PID) in the powertrain control module (PCM).
If the LOS_STRT PID indicates YES, perform Step 2.
If the LOS_STRT PID indicates NO, the DTC P1A0C may be the result of a 12 volt system fault. Performing the calibration update in Step 2 will not correct a 12 volt system fault. Follow Powertrain Control Emission Diagnostics (PC/ED) for DTC P1A0C.
Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 62.14 or higher and 63.02 or higher. Calibration files are not included on DVD 2009.9. Calibration files may also be obtained at www.motorcraft.com. The calibration contains a sludge compensation strategy for the throttle body.
Turn the key off to re-initialize the PCM. This will allow the sludge compensation strategy to learn.
With the vehicle in park or neutral and the climate control system set to DEFROST, start the engine and allow it to reach normal operating temperature (greater than 170 °F (77 °C) coolant temperature). Run it an additional 5 minutes to allow sufficient learning time.
While the engine is running, using IDS datalogger or equivalent, check the PID value of ETC_TRIM.
If ETC_TRIM value is 3.5 degrees and/or DTC P115E is present, then replace the electronic throttle body (ETB), following Workshop Manual (WSM), Section 303-04C.
If ETC_TRIM value is less than 3.5 degrees and DTC P115E is not present, but driveability concerns persist, the ETB is not the likely cause of the concern and replacement is not necessary. Continue with normal PC/ED diagnostics.

Re: "Stop Safely Now"
I just became a member of the SSN club this morning. '06 MMH, 98k miles. Came on when I was turning around in a cul-de-sac while delivering newspapers, and I heard a thunk/clunk right before the engine cut off. Gave a few second rest, then restarted. Got about 1/2 mile down the road, it came on again. It's 3:30 AM, so there's not much I can do to get assistance. I let it sit for a few minutes, then started it back up. Luckily I'm about 7 miles from home, so I am able to drive home in D and park it. Took it to the dealership after a four hour rest, and am told it's the MECS pump. Told him I was an "expert" because I read about it on the Internet, and he said that it did give the code for the bad MECS pump. Rainy weather that would make a repair outside messy, and I need the vehicle for delivering newspapers, so I didn't want to wait for a pump and repair myself. $750 lighter in the wallet, and hopefully will be good for another 98k. I'm really hoping the dealer can finish up today so I can get the MMH back for tomorrow morning. I don't like using my Impala SS for delivering, especially in the rain.

Re: "Stop Safely Now"
Apparently, I am a new member to the "Stop Safely Now" club as well. Bought my 2008 FEH in January 2013 with $58k miles. Up until now, the only issue I had was a cracked tone ring (which I was able to diagnose on my own thanks to this forum).
Driving on my first 200+ mile trip from Rockland, MA to Stowe, VT for vacation this week. Sunny weather, about 85 degrees, running with cruise control at 65mph. About halfway there in NH along Rte 89 (after stopping for lunch at a rest stop) I got the red triangle, engine shut off, and got the "stop safely now" message. Not much traffic thankfully, and was able to pull over without incident. I had not read this thread previously, so I had no clue as to what was going on. After about 5 min, I tried to restart successfully. Drove another half mile and the engine shut down again. Waited 10-15min this time, got another mile down the road with the same result. Called AAA for a tow, but knew since it was Sunday, I'd be waiting for a while (not that I had any idea where to tell them to tow me to!) After waiting about 20 min, my son in the back seat complained he was hot, so I started the engine and cranked the air conditioning. After the cabin cooled down, I noticed a sign that the next exit was a mile away, so I decided to at least get off the highway and update AAA with my location.
On a whim, I kept driving...no cruise control, never faster than 65mph. Made it the rest of the way up the mountains of VT to our destination. Feel pretty lucky. Now I am just leery about the eventual ride home.
So after reading and re-reading all 27 pages of this thread, I have gleaned the following possibilities:
MECS needs to be replaced (most likely)
Hybrid battery cables/harness may be corroded and need to be replaced
Relay(s) are bad and need to be replaced
TB (?) and actuator door may need to be replaced
My regular battery may need to be checked (?)
Am I forgetting anything?
So armed at the very least with TSB 09-19-12, and TSB 09-18-6, I know I need to go to a Ford dealer (I bought my FEH, used from a Chevy dealership) and get it scanned for trouble codes. I know from experience and from stories related here that going to the dealership can be frustrating and expensive. If anyone has any positive experiences with mechanics experienced in Hybrids in fixing related issues in Eastern MA, I am more than happy to listen.

Re: "Stop Safely Now"
Resolution: Pinpoint tests indicated bad PCM connections. That resolved the problem I was experiencing with the throttle body. After repair, however, SSN would still display after a short time. Further pinpoint testing pointed to bad blend door actuator. Replaced that to no avail. Hybrid battery was then replaced. I was able to source a battery from Advance Auto Parts. It was salvage from a 2008 Mariner with 50k on it and only set me back $350. Installation from the dealer ran right at $400. All in all, Throttle body + trouble shooting PCM connection + Battery + install set me back right at $1300. Not really terrible considering...

Re: "Stop Safely Now"
I hate to dump on you but I wonder why and what reasons the dealership stated a new hybrid battery needed replaced? You are only the second person I have heard that replaced their hybrid battery. Most of us would believe it is not the battery sticks inside the hybrid battery but something else that is at fault.
