NHTSA Complaint #11429281 — 2013 FORD EDGE

This is a known issue for the Ford Edge. The Voltage Regulator on the Alternator goes out prematurely. The SYNC system will shut down while driving and also disable many features of the vehicle. Such as the radio turning off, doors not unlocking, shifting disabled, headlights turn on dimly, etc. The battery tests normal and so does the alternator, however the regulator within the alternator will not pass through enough charge to the battery to stay charged. Hence, why most people will change the battery and still have the problem later. I understand as parts age they do fail, however this has been a known issue since early versions of the car and it has yet to be corrected. Many of the complaints on NHTSA are related to this, however some people are not aware due to lack of testing the particular item. They will write complaints about radio shutting off or headlights wont turn on(which is really dangerous as well). It often happens while driving, a warning will show up saying "Sync shutting down.....". Driver's are unaware that they are only driving on the battery power at this point because when they get it checked by a mechanic, both the battery and alternator test as they are supposed too. They alternator is still creating voltage however the regulator, not tested individually, won't allow enough to go through to recharge the battery. The most concerning part is if certain electrical components not deemed necessary by the SYNC system are shut down they could lead to more catastrophic incidents. For example; ABS braking not slowing the vehicle, door wont unlock in emergency situation, etc. I had both battery and alternator checked by a tech from Oreilly's Auto Parts and a mechanic from a local auto shop. I was informed that it must be the battery since the alternator is performing, So the battery was changed Friday 08/13/2021. Vehicle was fine until driving Monday 08/15/2021 and warning showed up again.
