pureenergi Posted September 9, 2020 Report Share Posted September 9, 2020 I scheduled an appointment to leave the car tomorrow for a full day and will update with what I find. After reading about all this, I don't want to take any chances. Fingers crossed it's just the RTV sealant, but I do (and my girlfriend rode with me to confirm) hear a hissing/grinding/(girlfriend described it as the sound of sucking through a straw) sound on accel and decel but not on coasting, and does seem more pronounced around 30-40mph. I'll make sure if they have it open to check that seal that they check for the grinding/thumping/rubbing issue. Maybe I have the RTV sealant leak and an early stage version of the worse issue? Either way, hopefully I'll know soon. Quote Link to comment Share on other sites More sharing options...
fbov Posted September 10, 2020 Report Share Posted September 10, 2020 Sometimes a fluid leak is just a fluid leak. Do you have any of the other symptoms? The tranny issue is well documented here, as you've found. If you don't have the other symptoms, your tranny may be fine. Frank Quote Link to comment Share on other sites More sharing options...

Expect about 10 hours of labor. So, you want to make sure that it will be covered under the unique hybrid components warranty which is 8 years / 100k miles or an extended warranty, if you have one. I doubt the RTV leak will be covered though. Quote Link to comment Share on other sites More sharing options...

I doubt the RTV leak will be covered though. Yeah, I was 99% sure that it would have to be pulled to check that. I pulled up to the shop this morning with a long, detailed note in Apple Notes with the TSBs for both issues and photos from this thread and a copy of the warranty PDF that details the 8 year, 80k coverage for the "Transmission Assembly (Plug-in Hybrid vehicles only)" and RTV sealant sure seems to me like a part of that, (warranty guide attached) but we'll see. I showed the check-in advisor at the shop (not my normal advisor) everything in the note and he said "let's not get ahead of ourselves" and I laughed and explained my concern that I just wanted to make sure it wasn't the worst issue. I did point out the warranty coverage and the TSBs so at least they know I've done some research but I'll report back either way. 13hybwa2e.pdf Quote Link to comment Share on other sites More sharing options...

The tranny issue is well documented here, as you've found. If you don't have the other symptoms, your tranny may be fine. Frank I do, I mentioned above that I brought it in for a grinding sound that I thought was coming from brakes and they found the tranny leaking. It's sort of a whispery SSSSHT-SSSSHHT-SSSHT as I accel and decel but does not exist while coasting or stationary. The sound feels new, as I don't remember hearing it before, so hopefully if they have it open for the RTV issue they check for that as well, but either way I have a (new to me) sound and I've owned the car since 2013. I've only heard clunks at times when shifting from R to L or D but that may just be sound from the shifter. Quote Link to comment Share on other sites More sharing options...
pureenergi Posted September 12, 2020 Report Share Posted September 12, 2020 Update on my issue: after having the car for a day and a half, service manager contacted me. It looks like the sound I heard was indeed the bearing/transfer shaft issue and they're replacing the entire transmission under warranty! It appears that being under 8 years/100,000 miles with the extended coverage on the Energi was what made the difference. It should be replaced with the current (mid 2015 and later) HF35 transmission. Should take about a week to get the part and get it installed. In retrospect, getting the first gen (2013 MY) of this new transmission was a risk, but I knew it wasn't an entirely new design, just an evolution of the earlier design so I thought I'd be good. I vaguely remember the extended plug in hybrid warranty powertrain coverage being an incentive to buy, and it looks like I wasn't wrong. This service experience makes me more likely to look at a new Mach-E as my next car, I'll tell you that . . . definitely heard from Tesla owners that the service experience is awful. fbov, WannaCMAX, takingittothemax and 2 others 4 1 Quote Link to comment Share on other sites More sharing options...

C-MaxA2 Posted September 12, 2020 Report Share Posted September 12, 2020 Had my first warranty claim on our 2017 C-Max (still under warranty under miles and months) for a dead LED running light in the headlight display. Ford approved it in less than an hour and it was done the next day. They replace the whole front headlight - $1,500 retail new. First time I've had a Ford warranty claim. pureenergi 1 Quote Link to comment Share on other sites More sharing options...
Josh Posted January 7, 2021 Report Share Posted January 7, 2021 I took my CMAX in just now because after a oil change i was told i have minor leak coming from my transmission but it wasnt enough to know where exactly the leak was coming from. So i took into Ford and they said the case was leaking and it need to be removed, "Torn down?", and resealed the whole repair will cost $2600!!! Does that sound right?? My check engine light is not on and when it sits in the drive way there is no visable leak, I feel like im being scammed. anyone else had this issue?

homestead Posted January 7, 2021 Report Share Posted January 7, 2021 What year is your C-max? Transmission leak & noise are the symptoms. Quote Link to comment Share on other sites More sharing options...

Attached is the TSB which shows over 10 hours of labor because engine / transmission has to be removed from vehicle to replace sealant. Also, note all the parts / supplies needed. So, $2600 seems a little high but it depends on dealer labor rate and MSRP of parts / supplies.
