Good luck and keep me updated. Interested to see if that fix works. I could see a TSB but they will never recall this. I can’t imagine what it is costing ford to replace an engine damper. Requires engine and transmission removal.
I know the damper are the sound we hear, and theyre probably junk. But I dont think replacing it will fix the shaking. It'll just make the shaking more silent? But I'm no mechanic..
The damper is also referred to as a harmonic balancer and its role is to also control vibrations. Like you said I’m no mechanic though so who really knows. I just hope they figure it out.
De-energizing is not the same as a "complete discharge". There is no reason to discharge the HV battery. They just completely disconnected the HV battery from the engine/eCVT so that it was safe to work on. At ~250 volts, it could cause death so you don't want it possibly energied while working around it.Received the maverick yesterday. I’ve included the work order in this post to help guide people and their dealers. It’s too soon to tell if this fixed the issue but I’ll keep this post updated with my findings. The fix involved removing the engine and transmission to gain access to the damper. The damper was replaced with a new one. It seems they also had to replace the engine coolant and completely discharge the high voltage battery. I’ll be keeping an eye on my high voltage battery because they said they ran into a “problem” getting that to charge back up to 100%. I honestly think they expected it to charge a lot faster than it does when in reality it takes a bit for that to happen while driving and braking. I am cautiously optimistic about this fix. It has worked for others with the same issue but this is their 3rd attempt to fix mine. Im also a little nervous about such an invasive repair in such a new vehicle. I definitely won’t be trying to fix this issue again if this doesn’t work and it’s going to be hard to not trade it in when I get a chance to get a 2024 Tacoma. We will see what happens. I also had the airbag recall done while it was there.
Good catch. Yes I assumed that is why they did it.
Great info. Thank you
My C-Max has a feature called EV+ that recognizes repeat stopping locations...like Home. When the car got to the last 1/4-1/3 mile of a recognized destination (whether stopping or not), it would automatically go into that mode with the intent of trying to DEPLETE the HVB as low as possible before parking. I'd think a 2023 would even manage the HVB better than the 2017 C-Max Hybrid does.
Thanks really go to @GPSMan, since he's the one who educated me on that topic. I gotta get one of those ScanGauge III devices he uses...
I haven't had any rough idle/shake since the quick fix.. And its still winter up here around -9C / 15F this morning. Maybe next winter, issue may re-appear..
Just thought I'd let you know I have a 2020 Escape HEV and I discovered this same issue by accident one day. That was before they replaced the flywheel/clutch damper at 23,000 miles. After the damper was replaced and everything was reprogrammed per the latest greatest update, it does exactly the same thing. Dealer is aware, Ford is aware, nobody has a fix. They feel it's more software related than mechanical, but must not be a priority for Ford to fix, plus it only happens in N. Of course I haven't had my vehicle since the end of January because I have the dreaded Deep Sleep Mode issue with the 12v battery going dead overnight. But that's another story of Ford not having it's priorities in order since that issue has been going on since the 4G Escape hit the street 3 years ago and it's still going on with the Escape and the Maverick.
