'13 Escape, 1.6 motor, intermittent high temp shutdown
We have a 2013 Escape with the dreaded 1.6L engine. It has 11,200 miles and this problem has happened 4 or 5 times. The last two times was within 10 days and 200 miles. This is what happens from everything being normal.
First indication is that the power steering shuts off. A safety concern.
A few seconds later the display shows engine overheat with the admonition to service immediately. The engine temp gauge is full scale hot. Cooling fan comes on. Engine icon is illuminated. If you do not pull over and stop, the engine goes into a "limp (crawl) home" mode where the vehicle will barely move on level ground and not at all up a hill.
Shut the engine down, wait a minute or so and restart. The overheat indications may come on again with no power steering. Or, all indications may show normal except the engine icon is still illuminated. The engine is not actually overheating and coolant level is normal. Sometimes you have to go through this re-start process several times before you can drive the car.
Weather, road condition, or outside temperature doesn't appear to be a factor. I've driven the car to the dealer and had it flatbedded to the dealer without re-starting the engine with the same result.
The report will show:
F1 Recall 13s12 was completed. Go to F2
F2 DTC U1035 retrieved. Go to F3
F3 Coolant level connector pins ok, Go to F4
F4 12.2V go to F5
F5 .5 ohms go to F67
F6 .6 ohms. Install new coolant stand pipe.
R&R coolant stand pipe.
Test drove vehicle and code didn't come back.
200 miles and 10 days later the same thing happened.
After multiple restarts and waiting periods I drove it 80 miles to the dealer and tests showed:
F1 13s12 recall completed go to F2
F2 Cleared DTC and no DTC returned. System is working correctly at this time. DTC may have been caused by high network traffic.
Test drove vehicle multiple times over three days and no codes have been set.
This condition has happened a few times in the months previous with the same results. The coolant stand pipe replacement didn't help. Nothing else has been replaced for this problem.
The build date shows 5/13 on the door post placard. The VIN is 1FMCU9GX8DUD70681.
I checked the battery terminals and other electrical connections in the engine bay and all appeared tight.
I couldn't find a similar problem by searching the forum threads. The overall unreliability of this Escape has me unwilling to get very far from home with it.
The dealer is helpful, but doesn't know what else to do other than advise me to bring it in next time it happens. Ford won't let them replace the main ECU.
Anybody have a suggestion?
