After 100K miles of no issues with my OEM installed battery and basically trouble free driving, I got a wrench warning but after turning off the car the wrench went away so every time I took the car into to my Ford Dealer Service Center, without the wrench, they could not diagnose the issue. Finally, I left the car running when I got the wrench and brought it in. From visit service technician notes: Used IDS and pulled codes P0A7C and P0130. Reprogrammed PCM to its latest calibration and retested it. Tested fine.
Shortly thereafter, i found my car had a dead battery after sitting 2 days. Took the car in after a jump and the Service guy performed an EEC test and I quote from my service record the following: "found P0130, CMDTC, KOEO, KOER passed. Checked Oasis found TSB 10-17-11 found PCM to the latest calibration. Performed PPZ DZ. DZ1=Y, DZ10=Y, DZ11=Y, DZ12=N DZ13=N DZ23=N. INAPECT connector no faults found. Replaced 02S11. Clear DTC and road test. Passed." I also had a battery test. "Charging System passed, battery test failed only 75 CCA. Recommend replacing battery. Which I did.
Since then I have had to jump start my car 3 times, and replace the battery once more. The technician indicated I got a bad brand new Motorcraft battery. Last week, the battery was dead again after sitting less than 36 hours. My car is currently in the shop again. After performing some tests and calling the Ford Super Technicians for help, my dealer has come back to me asking me to approve additional costs of $650 to continue troubleshooting the drain. Not $650 to fix the problem, but $650 to continue troubleshooting. They have tried removing fuses one by one to isolate the issue. They are apparently getting closer, but want me to pay for their troubleshooting. They are basically saying, we will not do anymore work on your car until you authorize us to spend my money to fix the problem.
Two things are apparent... first of all, my OEM battery which I had replaced really didn't need replacing in the first place. It was still perfectly good. Second, Ford software upgrades have apparently started a drain on my battery and since the super technicians cannot give these guys instructions on how to solve the problem, they want me to pay for the research and development of a problem they caused. So I came back with a fair and reasonable offer... since every future occurrence of this issue will have a known recommended solution, you are asking me to pay for Ford to troubleshoot the solution, I'll meet you half way... I'll give you $325 (half) and I think Ford should pay the other half, after all it is apparent a software upgrade caused this issue. I also said, if you find it was a rodent chewed wire that caused this, like the service manager suggested a possible cause, I will pay the full $650.
If there is anybody monitoring this site and understands the frustration I am going thru and knows what to do, I would love to hear from you. I wish I knew the phone number of the super technicians at Ford to discuss this matter with them directly. Ford Motor company does not own the dealership, I get that. The dealership does not want to work for free, I get that. Ford has done something to my car, not the dealership, I get that. Why can't Ford step up and admit they caused the problem and help solve this without me paying for troubleshooting time, just ask me to pay for a reasonable amount of fix it time to get this resolved.
Meanwhile, my dealership does not offer loaner cars, so I'm also out the continuing cost of a rental. This just doesn't seem right, or fair.
