pianewman Posted November 13, 2019 Report Share Posted November 13, 2019 2013 CMax Hybrid, 100k miles. 4th OEM battery installed at 97k, now failing. Radio/nav has failed several times in our 3 years of ownership, always resetting itself after pulling a fuse, or...after each battery disconnect/replacment (3 replacement batteries!!!!) Entire entertainment window is now black. Dealer just phoned, says it's the APIM module, $1k+ to replace, WITH NO WARRANTY after replacement. ??????? YES, he says, they fail all the time. YES, he says, Ford hasn't figured it out, and the entertainment module/software is sold to them, "by a vendor that visits" the dealership. He claims the vendor isn't even a Ford employee. ????

stratosurfer Posted November 13, 2019 Report Share Posted November 13, 2019 Read my post about upgrading from Sync2 to Sync3 which you can do for less than $1,000 with all new components, you'll leave out navigation as Sync3 has Apple and Android play so you'll navigate by Waze or Google Maps broadcast from your phone. Go to Ebay and search Sync3 upgrade. Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted November 13, 2019 Report Share Posted November 13, 2019 I'll bet the APIM is the current drain. It's been known to be the source of high current drain. You can replace the APIM yourself with a used one. There are videos on-line that show how to remove / install and to program with FORScan if the APIM isn't from a C-Max. You can probably DIY for a few hundred $$ including buying a OBDII Elm327 adapter and the FORScan app that allows programming (IIRC, windows free version with free extended license for a couple months). You can also buy a used APIM from companies that will program it for your VIN but at about 2X+ the cost of a used one. Also, perhaps a shop that does car audio can do the install for a lot less than $500. https://www.flvpmods.com/apim-replacement.html Quote Link to comment Share on other sites More sharing options...
pianewman Posted November 14, 2019 Author Report Share Posted November 14, 2019 Dealer phoned later in the day, told me the equipment they used to check for parasitic drain killed the battery overnight. I asked about the possibility of the failing APIM fully draining the battery, and tech says he's never seen/heard of that before. We're in west Ft. Worth, the dealership sells a zillion trucks, and services very, very few hybrids, so... I'll be speaking with them again tomorrow. Hope to resolve this. So far, since I'm out of the 5 years extended warranty on the APIM, dealership won't help with replacement cost. My service adviser, who is totally straight with me, says he and his fellow advisers catch a lot of flack from customers about failed APIM.

plus 3 golfer Posted November 14, 2019 Report Share Posted November 14, 2019 Do an internet search “APIM dead battery drain”. Owners of many Ford products have had the dead battery issue when experiencing problems with Sync 2 APIM. Coincidence? I highly doubt it.

This is (among) my main reasoning that it is worth it to consider the sync2 to sync3 mod/upgrade. At this point a Cottage Industry has sprung up to support this upgrade.

pianewman Posted November 14, 2019 Author Report Share Posted November 14, 2019 All good advice here. We have to decide if the value of the cash outlay (hardly an "investment"!) is worth it to us, and how long we plan to keep the car. Quote Link to comment Share on other sites More sharing options...
