Donaldj79 Posted September 19, 2023 Share Posted September 19, 2023 My Dad has a 2014 Fusion Hybrid with over 200k miles. Over the Summer, he kept getting the message "Motor Over Temperature." He would pull over let the car cool and begin driving it. He took it to a Ford Dealership for a diagnostic and they printed out the Codes and did a Recall and gave him the car back without charging him. We figured out how to read the temperature gauge and had another mechanic loook at the car. No leaks. No coolant loss. The gasoline motor was not overheating, but it was the hybrid system. I suggested my Dad by a Coolant Pump (although there was no code) in hopes that would solve his problem. He continued to drive his car against my better judgement. The last time he drove it, he said that the car made a loud rumbling sounds and it would barely move down the street. The battery ran down and when we tried to restart it, the gasoline motor will not engage. The car will start and say "Ready" on the dash and it will move a few feet if that. Immediately the dash will say "Stop Immediately." Usually the gasoline motor starts shortly after moving. Now it doesnt engage at all. What part(s) could he have damaged by overheating the car so much?? Where do we start to get the car fixed? Here are the 6 codes we pulled up: P1A0C-Hybrid Power Control Module P0A92-71-Hybrid Generator Performance-Actuator Stuck P0A3C-Drive Motor A Inverter Over Temperature P2531-Ignition Switch Run Circuit Low U0412-Invalid Data Received from Battery Energy U0121-Lost Communication with ABS Module 0 Quote Link to comment Share on other sites More sharing options...
BEERGUY Posted April 9 Share Posted April 9 Your dad is lucky that his 2014 Fusion Hybrid (HEV) made it over 200K before these problems. My 2014 Fusion Energi Titanium (PHEV) isn't as lucky. AT 105k my ECVT HF35 Transmission leaked fluid and Ford replaced it with a refurbished one under warranty. At 141k it started to go into limp mode with "Stop Safely Now" and died on me but it'd kick into the EV mode only & run until there's no more EV power. Replaced a lot of hybrid related parts and I figured it has something to do with the fuel shutting off the gas engine. I suspected the Transmission Inverter Control Module (TICM) is bad & got a used one from junk yard ($300); a new is $2200 (4/1/24). Replaced the PCM with another & same issue, replaced the ETB (electronics throttle body); checked relays and fuses, a secondary coolant pump (for hybrid, there are two electronics pumps--not to be confused with the has motor water pump--that's separate). I took it to 4 different Ford dealers, most says you're SOL. Only 1 advisor was good enough to go the extra mile & asked Ford to fix the HF35. Most techs I questioned on hybrids/EVs are dummies including service advisors--they only pretend they know it all--just pay the $235 diagnostic fee(s). It seems like these cars are made to go to 150K and then it's a POS. My next hunch is to replace the fuel pump itself which seems to be intermittent and it's buried in the gas tank--not accessible from the back seat as many said. Clear codes, get the FIXD OBD2 scanner. So far this thing seems to be on point (no affiliation to FIXD). And you're right, make sure to use different coolants on this car, they're not the same!! one will conduct electricity and the other doesn't (Hybrid Motor Electronics--TICM). Also, use the bottom shield and spray rodents stuff to keep them out. 0 Quote Link to comment Share on other sites More sharing options...
WKelley Posted April 11 Share Posted April 11 It's used up. 200K miles on a hybrid is a gift, he should cherish the memories. It would be very cost restrictive to fix it. 0 Quote Link to comment Share on other sites More sharing options...
