Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Ford Bronco Sport · 2021–2024
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 48,041 vehicles previously repaired incorrectly. Dealers reflash control modules and/or replace the battery free of charge.
Common Symptoms
- Vehicle stalls at low speeds or when coming to a stop
- Engine does not restart after Auto Start-Stop activates
- Loss of interior lights and accessories when stalling
- Air conditioning cuts out unexpectedly
- "Remote Access disabled to reserve battery" alert in FordPass app
- Battery warning light
- No-start condition
How to Fix
Ford Safety Recall 24S24 is a free BCM and PCM software update at any Ford dealer and takes approximately 1-2 hours. Because the first remedy was not always adequate, check your VIN at fordowner.com or safercar.gov for all three campaigns: 24S24, 25S02 (battery replacement) and 25S26 (re-repair). If experiencing stalling or no-restart issues before recall service: disable Auto Start-Stop feature (button typically near shifter). Replace 12V battery if it is weak or over 3 years old as preventive measure.

Porsche Taycan · 2020–2025
The Taycan 12V auxiliary battery drains excessively when the vehicle is parked, even for short periods. On cars with the factory A123 40 Ah lithium (LiFePO4) 12V battery, Porsche bulletin SY 36/25 says the battery's charge state is not calculated correctly over the vehicle's service life, which can leave the car de-energized. A dead 12V battery prevents the car from powering on even with a full high-voltage battery.
Common Symptoms
- Vehicle will not power on despite full main battery
- 12V battery warning on dashboard
- Keyless entry not responding
- Dashboard going blank after short parking period
- Need to jump-start 12V system
How to Fix
Ask a Porsche dealer to apply bulletin SY 36/25: fully charge the 12V battery with a lithium-capable charger, then reprogram the battery sensor with the PIWIS Tester. Porsche describes this as a temporary measure while a final fix is developed, and says replacing the battery does not correct this fault. The factory battery is a lithium (LiFePO4) unit, so any charger or replacement must suit a lithium battery. Install a 12V battery maintainer for extended parking. Disable unnecessary always-on features in the vehicle settings.

Porsche Panamera · 2010–2025
The Panamera is prone to excessive parasitic battery drain when parked, often caused by modules failing to enter sleep mode. The numerous electronic systems (air suspension, PDCC, keyless entry, PCM) can draw excessive current when the car is off. The battery can drain to the point of no-start within 1-2 weeks of non-use.
Common Symptoms
- Dead battery after 1-2 weeks of non-use
- Slow cranking after sitting
- Dashboard warning lights after jump start
- Battery replacement needed every 2-3 years
- Keyless entry intermittently not working
How to Fix
Perform a parasitic draw test to identify the offending module. Common culprits include the PCM head unit, telephone module, and comfort access system. Install a battery maintainer for vehicles that sit for extended periods. Replace the battery if it has been deeply discharged multiple times.
What you need to diagnose it
The fix here starts with a test, not a part — which repair you need depends on what the test finds.

Testing and isolating the fault is DIY work. Replacing or reprogramming a control module is not — most are VIN-programmed, so a new one does nothing until a shop codes it to your car. Check for an open recall or service bulletin before buying anything.

Frequently asked questions
What does P0562 mean?
P0562 stands for "System Voltage Low." P0562 means the engine computer detected that the vehicle's system (battery/charging) voltage is too low for normal operation. The computer constantly monitors charging-system voltage because nearly every sensor, injector, and module depends on a stable supply; sustained low voltage can cause erratic behavior and other false codes. This is most often a charging or battery problem — the alternator isn't keeping up, the battery is weak, or there's resistance in the cables/grounds. You may notice dim lights, slow cranking, or multiple unrelated warning lights.
What are the most common causes of P0562?
The most common causes of P0562 are: Failing alternator or worn alternator brushes/regulator, Weak, old, or discharged battery, Corroded, loose, or damaged battery cables and terminals, Bad engine or chassis ground connections, Slipping, glazed, or broken serpentine/drive belt, High resistance in charging system wiring or fusible link, Faulty PCM voltage reference or charging-system control. The specific cause varies by vehicle.
How much does it cost to fix P0562?
Repair costs for P0562 range from $10 to $3,000, depending on the vehicle and root cause.
