Had my Focus Titanium+ (mfc. June 2013 reg. July 2013 @ 14000km) not started since Tuesday evening to Saturday evening (4 days) but had no problems or difficulties starting it.
Also, I had checked the battery at the SC after hearing over these issues with a few of the owners (now urself) but the charge was good. Also, have a bluetooth OBD2 scanner to monitor the pre-crank, crank and post-crank charging voltage & I have something like this; pre (11.7), crank (~10.9), post (12.6 when idling, 13.4 when cruising).
From the research done, a defective battery can't retain the charge, so the crank voltage may even dip below 10/9v & pre-crank may be in it's 10s.
2 possibilities you may look into; current being drawn when no in use - electronics including screen are shut off in 20 mins from ignition off, if doors are unlocked. If doors are locked, it happens nearly immediately. Second possibility is a faulty battery that could have been kept too long in storage (under sun) before transported to Malaysia.
My advice, I'm not sure about the SC you're going to but I can advice you to try SDAC, PJ & speak to the branch manager there - well spoken and if he is informed beforehand, your issue would most likely be addressed in the best possible way. You may try the same with the other SCs instead of raising your issues to the foremans or mechanics first.
I really hope the culprit is the faulty battery. like i say earlier, once i got the new battery from puchong sc and problem persists then i have to no choice but to send car to PJ
