Did it run out of oil? Looks like a lot of metal missing. Before attempting a repair, are you sure you can find all the broken metal that may have circulated into the rotors, magnets, oil passages, cooler? What does the filter look like? Do you need #83 and #84? The basic part number to ask for is: 83 7D234 Sun gear thrust bearing 84 7A348 Sun gear  

Welcome to the forum. Try the CMAX forum. It might be more active.  https://fordcmaxhybridforum.com/  I think they share the same engine and transmissions.  Since you obviously have the skills you can always try pick your own junkyards junkyarddog.com  Let us know how it goes.  What do you think caused the problem? 2018 isn't that old but 195k is a lot of miles for a 5 year old car. 39,000 miles a year, yikes.

Reviving an old thread. The camera from Amazon stopped working after 3 years. Got another one for $44 and will do the swap again. I still can't pay $287 for an OEM camera. I also don't want to risk one from the junk-yard.

2018 Fusion Hybrid, 195k miles.  I've had loud engine noise when at low speeds for maybe a year.  About a month ago, it shut down on me on the highway.  I was getting a P0E4E code (Engine lockup) and P088E (planetary failure).  When I got it towed home, the engine was locked up.  I dropped the transmission, and the engine would turn.  So, I broke apart the transmission, and found the planetary gear assembly, ring gear, oil pump gear, the sun gear and it's thrust bearing all torn up.  Everything else looks fine.  Ford sells everything but the sun gear and its thrust bearing.  They can't even supply the part number.  From what I can find, the H4F45 transmission in the 2020+ escape Hybrid is the same, but still can't find the part number.  Does anyone here know where I can order these from?

Oh no I am so sorry to read of that.  There was no way to park it in high ground huh?  Hope your insurance helps you.  Crazy how the west side of Florida got hammered the most. How many miles did you have? Here's a nice white one that was listed before the hurricane.  https://tampa.craigslist.org/psc/ctd/d/land-lakes-2018-ford-fusion-hybrid/7787933156.html

Yes you can put the car into brake service or maintenance mode. Turn the key to accessories but don't turn the car on.  Put the transmission in neutral> hold the accelerator pedal down all the way.> then hold the parking brake button down.> then turn the key off and then back on>then put the transmission in park and take the key out. (It is like an old video game cheat code) Set brakes into maintenance mode To undo it follow this. How to exit brake maintenance mode. Brake Maintenance mode with a push button start   Also, Autozone has a brake caliper loaner tool which you can borrow for free with refundable deposit to compress the caliper pistons.  https://www.autozone.com/brakes-and-traction-control/loaner-disc-brake-caliper-tool/p/oemtools-front-and-rear-disc-brake-pad-spreader-set/298604_0_0   I did my rear brake pads myself and it was the easiest brake job I ever did.   You'll also notice the shocks and the springs are separate on the rear too making replacing them easy as well. I am happy Ford keeps some things simple.  

Remember what I said above about hurricanes? Well Helene got me, car is totaled. Salt water got up inside and fried lots of little things. WHen I opened the door it smelled like melted insulation and electronics were wacky. Couldn’t figure out how to get it into Neutral for the tow truck and the guy just dragged it up onto the flatbed. It was a good car, will miss it. Since they haven’t made any since 2020, I’ll probably be getting a 2-3 tear old Camry Hybrid now. 

I’ve never done it, but see the post from Sky14FFH  - says it’s pretty easy.

Probably blew the 50 amp or 15 amp fuse under the hood. The 50 amp is hot all the time, so it doesn't matter if the key was off.    Real bad idea cutting wires. Could have also fried the engine computer as one of the circuits is also in that connector.  If you don't splice in the wires properly, you will end up wire corrosion which shows up later.    At least disconnect the battery next time

I bought my FFH at 125K miles. The throttle body was very black and dirty and so I cleaned it with carburetor cleaner. I also removed the MAP sensor and cleaned it with mass air flow sensor cleaner. DO NOT USE carburetor cleaner on the MAP sensor!   I have read that the atkinson engine in the FFH causes the throttle body to become dirty. That makes sense to me because the intake valves remain open a short time into the compression cycle.
