P0562 on Ford

A recurring owner complaint on newer Broncos is unexpected battery discharge after sitting, sometimes leading to a no-start condition, multiple warning messages, or modules behaving erratically. Reports often mention the vehicle being parked for only a few days before the battery is too weak to crank, with some cases linked to software/module sleep issues or accessory loads. The problem is documented in owner forums and complaint databases, though root causes can vary by vehicle.

NHTSA recall 24V267000 (Ford reference 24S24) covers 456,565 model year 2021-2024 Bronco Sport and 2022-2023 Maverick vehicles. The Body Control Module and Powertrain Control Module fail to detect 12V battery degradation, resulting in loss of motive power whenever an Auto Stop/Start event occurs or during low-speed braking. Two follow-up campaigns address inadequate initial remedies: 25S02 (NHTSA 25V019, January 2025) replaced defective Camel EFB batteries with Ford AGM units on 272,817 vehicles, and 25S26 (NHTSA 25V158, March 2025) re-fixed 12,833 vehicles previously repaired incorrectly. Dealers reflash control modules and/or replace the battery free of charge.

The alternator on both 2.0L and 2.5L V6 engines fails prematurely, often before 80,000 miles. The voltage regulator or diode pack burns out, causing battery drain and electrical issues. The 2.5L V6 alternator is particularly difficult to access.

The alternator fails prematurely, often due to the internal voltage regulator burning out. Causes battery discharge, dim lights, and eventual no-start. The 2.0L Zetec engine alternator is slightly more reliable than the earlier 1.9L unit.

Sixth-generation Explorers commonly have the Auto Start-Stop feature stop functioning, showing 'Auto Start-Stop Not Ready.' The most common causes are a weak or degraded battery, a failed auxiliary/AGM battery that supports the restart function, or an inaccurate battery current (monitoring) sensor feeding bad state-of-charge data to the module. Software calibration errors are also a factor. Because the system requires a healthy battery and accurate sensor data to safely re-crank, any of these will disable it.

On certain 2019-2020 F-150s, the fastener securing the Power Distribution Box (PDB) 12V cable and the Battery Monitoring Sensor (BMS) eyelets to the positive battery terminal may not be properly torqued, partly due to leftover wiring-eyelet adhesive on the BMS terminal interfering with metal-to-metal contact. This 'soft joint' creates intermittent high resistance that can cause flickering or inoperative instrument-panel displays, loss of braking or steering assist, and engine stalling. Worse, the resistive connection can overheat, leading to smoke, melting, or fire. Ford issued Safety Recall 19S40 (NHTSA 19V805) covering about 135,725 U.S. vehicles built at the Dearborn and Kansas City plants in mid-to-late 2019. This is a positive-terminal connection defect — separate from negative/ground cable corrosion no-start gripes and distinct from the FPDM corrosion issue. The related positive battery cable assembly is Ford PN JL3Z-14300-E.

The Lightning's 12V battery is only recharged by the DC-to-DC converter while the high-voltage battery is charging or the truck is on, so parked trucks can experience 12V undercharge and parasitic (vampire) drain despite a full traction battery. Owners widely report "Plug in to maintain 12V battery" and "electrical system power reduced"/"electric system drain" messages, low 12V state-of-charge, and no-start conditions after sitting. A depleted 12V battery is also a leading cause of failed OTA updates.

The alternator fails prematurely on the 3.0L Duratec engine, often before 100,000 miles. The internal diode pack fails, which can also cause parasitic battery drain even when the vehicle is off.

The 2000-2007 Ford Taurus experiences premature alternator failure, with some units failing as early as 34,000 miles according to Taurus Club of America forum reports. CarComplaints.com documents alternator failure as a reported issue for the 1997-2007 model years with an average repair cost of $270 at 135,750 miles. The 2002-2007 generation appears most affected based on forum complaint density. YourMechanic.com estimates alternator replacement between $533 and $695 for most Taurus model years. Symptoms include dashboard battery warning light, dimming headlights at idle, difficulty starting, and eventual complete electrical system failure and stalling. The internal voltage regulator is a common failure point, along with bearing wear that produces a grinding noise.

Ford Transit vans experience premature alternator failure, often between 50,000-80,000 miles. The internal voltage regulator fails first, causing undercharging or overcharging conditions. Commercial Transit vans with aftermarket upfitter packages (extra lighting, inverters, refrigeration units) are particularly susceptible due to sustained high electrical loads. Symptoms often start as intermittent battery warnings before progressing to a no-start condition.
