I have a question about my car battery draining?

Asked by Guru9LPG1W Sep 08, 2021 at 03:54 PM about the 2016 Ford Mustang

Question type: Maintenance & Repair

My daughter has a 2016 Ford mustang. Her car battery keeps going dead.
The mechanic replaced the alternator and the same thing happened. He put
in a new battery and 2 days later the battery is dead. The mechanic ran
numerous tests to check if there was a problem with fuses etc. He came up
with nothing. As of today the mechanic said he thinks she shoud take her car
to a Ford dealership as he is stumped and cannot figure out why her battery
is draining. Any ideas?

Find a mechanic that knows how to find a parasitic battery drain. Dealers are super expensive so I would recommend a competent independent wrench.

Does she have any aftermarket accessories installed on the vehicle. Like an aftermarket stereo, for example. If so, I'd be looking at those things first. Also be sure no lights are staying on and the HVAC motor isn't running after the vehicle is shut off. The electric radiator cooling fans, if equipped, are suspect too. Hope that helps! Jim
