To complete this topic, our dealer has replaced the transmission. This appears to have resolved the issues described above.

Plus 3 - I have had to transfer my video files to Amazon's cloud as I have more space there. The link is - https://www.amazon.com/photos/shared/vm1qB6S4QlK9HhHUBRyFEg.QD-VW-xobjA9KSOnVTNvhv There are several additional videos of the backing issue. You asked to show one from the rear to determine status of the brakes. I can't tell for certain, but it appears they don't stay on. It's difficult to tell, since my reaction as soon as the vehicle jerks is to step on the brake. See what you think. We did attempt your suggestion to back up, then come forward, to see if it occurs then. It did not, but we'll try it again, since the event only occurs about 50% of the time. I have not attempted to turn off traction control yet. Again, thanks for your help.

Plus 3 - my apology for not getting back sooner. In your first paragraph you asked several questions. Here are answers to several - > Did you show the video to the dealer? Yes, they were supplied this and one earlier video. > What's the grade when you back out and stop? Is car level, uphill or downhill? When backed, the grade is uphill at a pretty steep angle. However, we have had the jerking occur on slight grades as well as on level ground. > Steering wheel is turned going backward. Then, when shifted to D, it appears that the "jerking" occurred as soon as the steering wheel was turned to go forward and then twice more as wheel is turned. This is correct. > Does the bucking happen if you pull back towards the garage and not turn the steering wheel? Have not tried this, but will do so. > Do you know if the event happens if you accelerate briskly from a stop? Yes. The jolt is greater, the greater the attempt to accelerate. So, to gain the hill from our driveway, one has to accelerate. Once in traffic on a slight slope, accelerating from the signal at a normal rate you would use in traffic, the car jolted to a complete stop. The car behind nearly plowed into us.

Plus 3 - thanks for the comments. I will pursue your suggestions and report back.

The following forum entry was submitted to an issue posted several years ago. I am repeating it here, since we have not been able to find a solution here or via our dealership. We have a 2013 Hybrid SE. Hill Start Assist on our 2013 vehicle has recently started acting up. (Down Grade Assist has been an issue as well. More on that below). We live on a hillside. To exit our drive, there is a short level section as we back from the garage. As you back, you turn to aim up the driveway. Inconsistently, after you apply the brakes and shift to Drive (or Low), on accelerating the car bucks and jerks stopping for a second. This same condition will occur in traffic when stopped on a grade; but again inconsistently. (This is of major concern, since the car starts forward, then suddenly jerks to a stop and drivers behind us have nearly plowed into us.) Timing seems to be a factor. If you wait more than about 2 seconds between removing your foot from the brake pedal and pressing the accelerator, chances are higher it will occur. Subsequently an unusual sound will occur following the jerking; like the tranny is in some other gear, but that's speculation on my part. If you have any information on cause and resolution of this, please advise. The (down) grade assist feature, since early in our ownership, has had an issue as well. If activated for a down grade, then turned off nearing the bottom of the hill, one needs to pump the brakes before braking to a stop. If you don't do this, and apply the brakes to reach a full stop, the car will jerk twice as it stops; but again, this is inconsistent. These jerks are not nearly the magnitude as the Hill Assist issues, above, but are a concern. We have stopped using this feature, but would like it, if repairable. We have videod the issue. It is parked online for review. Here is the link - https://1drv.ms/v/s!Ap1n9TQWS-TDkh4e3zMAEeY3j7kt?e=xTwOeh Yes, our dealer has checked for and assures us that all applicable reprograms/TSBs have been installed.

So as not to leave this issue/topic without closure, here is a status/update. We left our car with our Ford dealer service department for several days to see if they could (a) replicate the issue, or (b) inspect for faults and mechanical issues. They were not successful in either replicating the issue or finding mechanical issues. In the several days since we're had the vehicle back, the issue continues in a random fashion as described in my 7/20 post. Would it be a good idea to create a new post on this issue? Also, what is your opinion of the "On line Mechanic" advertised on these forum pages?

Plus 3 - I've found etis.ford.com reluctant to accept my attempts to register, then review my VIN info. Can one register as an independent entity? (I've left an email for them, but no reply yet.) Thanks. MN

All - thanks for the replies. PLUS3 - "Was there work just prior to issue". No. "What sound does it make?" Whooshing. "Everytime?" Event does not occur each time and neither does whooshing sound." fbor - Recall/reprogramming - Some module updates have been done, but to be honest, I have not been diligent in tracking these and my service reports are not explicit. Is this information accessible anywhere/should the dealer have this information on record? Ford?

We have a 2013 Hybrid SE. Similar to GSMacLean, earlier, Hill Start Assist on our vehicle has recently started acting up. (Grade Assist has been an issue as well. More on that below). We live on a hillside. To exit our drive, there is a short level section as we back from the garage. As you back, you turn to aim up the drive. Inconsistently, after you apply the brakes and shift to Drive (or Low), on accelerating the car bucks and jerks. This same condition will occur in traffic when stopped on a grade.

We have stopped using this feature, but would like it, if repaired.

This was/is a very good thread. Appreciated the link to TSB10-7-13. In my case, I now have 2 months experience with this TSB installed and have not had a recurrence of 12V system loss. Hopeful this issue has been resolved...

Bill -N Thanks for your reply to my post. My response to your questions: - By "shut down" I did mean battery failure with characteristic failure of key function, lights, and other electrical devices. - In my situation the car had been left overnight following a lengthy drive which should have kept the DC system fully charged. One curious item we noticed - when the car was jump started (cables to 2nd vehicle) we noted the radio came on. We had NOT been using the radio nor were we SYNC'd by cell phone at the time we shut the car off. - Do we know whether the TSB was installed? I can only go by the service report which says they installed and confirmed same. - RE: Lemon Law - ours has a 15 day "out of service" clause. Does that mean one has to leave it with the dealer for a total of 15 days or does it refer to total days with the issue unresolved? (I suspect the former, right?) Finally - I see 3 theories possible: (a) the batteries themselves are defective (unable to take & hold a charge, for example); (b) the charging system itself is at fault and does not charge the battery fully (on all or certain occasions), and © there are drains to the 12V system after shut down. On the last one, at least, shouldn't use of an Amp Meter identify the post-shutdown draw and with this knowledge identify which device(s) have that amount of current associated with it/them? FORD - I suspect you monitor this forum. Come on guys and gals, get this resolved!

Bill - I've reviewed your post after finding it by a search on TSB 13-6-23. My CMax was in for its 5K service PLUS a recurrent (3X since 12/2012 purchase) 12V battery failure. I was curious what the TSB might say. Of interest - the last shut down occurred last week following an all day drive (6 hrs with intermittent stops) in 80 degree weather. Thus, I suspect application of this TSB and associated reprogramming was a shot in the dark. Might you have other information or advice. "Apprehensive in Seattle"
