I have a 2015 FFH SE 106K miles with a bit of an issue. When I go through the tunnel carwash my trunk opens and my memory seats recall to random positions. I don't have push button start, so it's definitely not a issue with the key fob. The only cause I can think of would be the touchpad, but the touchpad does not control the seat memory settings to my knowledge. I know it's a somewhat common issue for the keypad to cause the trunk to randomly open due to UV and water damage, but I haven't seen any mention of the memory seat issue mine is having. It ONLY happens in the tunnel wash. Any ideas as to what's causing this issue and how I would approach diagnosis? I know there are CAN BUS modules all over the car, so I'm a bit lost. I'm a bit nervous this could the the start of endless electrical nightmares. Any help is greatly appreciated! If this is a bad sign of expensive and complicated electrical issues, I may end up trading my baby in.

After attempting to update my 2013 Ford Fusion Hybrid SE from SYNC 2 version 3.6.1 to SYNC 2 version 3.10 (I read online this was possible from a fusion forum) I got this error telling me to bring my car to the dealer.(see attached photos) I tried to fix the error, revert the update, nothing worked. I can’t even navigate the menu on my SYNC to try to reset to factory default settings. When I press settings it takes me to NAV and it seems the touchscreen doesn’t know what place the buttons are in the GUI. At the same time my car also has been dying after not driving it for a day or 2. I had just brought it to Ford a few months prior for the same issue and they had found the issue to be the 12v battery was the incorrect size so, I paid for a replacement 12V Ford motorcraft battery for $250. Since buying the replacement battery the problem is still occurring. I found this after attempting to update my car to 3.10, when the software was no longer responding to my inputs, and it was unresponsive. I didn’t drive it for 2 days. I can’t even connect my phone with bluetooth. After the 2 days of letting my car sit pass I then tried to access the Sync menu to try to fix the update, my car was dead again and I had to jump start it. After jumpstarting it and learning that I couldn’t fix the SYNC update, the battery went dead again overnight. So now the battery won’t even hold the charge for 1 day. So I brought my car to Ford and tried to explain everything. They we’re very unhelpful through the entire process and my car was there for over a month before they told me that there’s nothing they could do. They said that there’s an internal short in the BCM and this is why my battery is not holding the charge. The BCM controls the power windows, power mirrors, air conditioning, immobilizer system, central locking, etc. A malfunctioning BCM will activate dashboard instrumentation cluster error and warning lights. These lights may flash off and on if the BCM is not able to read the sensors correctly. Your vehicle performance may also be affected as the BCM communicates with other control modules in the vehicle. Now i’m worried because Ford says there’s no replacement parts for the BCM as it’s VIN specific. What do I do? They didn’t help with my SYNC update issue AT ALL with all the time the car was sitting there i’m unsure why they couldn’t simply flash the update and fix the bricked software. But this is why I’m here, If you have any info please help. Ford is dropping off the car in 2 days and I’m in the same place I was 1 month ago.?

This is just some interesting info I came across about how the LVB (12v battery) is monitored. === Battery Load Shed The BCM uses the battery current sensor to keep track of the battery state of charge. The battery current sensor is a Hall-effect sensor attached to the battery ground cable. When the engine is off, and the BCM determines the battery state of charge is below 40% or 10% of the charge has been drained or 45 minutes have elapsed, a load shed message is sent over the CAN. This message turns off the audio/navigation system to save the remaining battery charge. Under this condition, SYS OFF TO SAVE BATT is displayed on the centerstack infotainment display to notify the driver that battery protection actions are active. Engine off load shed occurs when the engine is not running, and the ignition is in the ACC or RUN position. To clear the load shed state, restart the engine. = This is a picture of where the Sensor (in Blue) on the 12v battery Ground cable is located.
