P0562 on Hyundai
System Voltage Low
P0562 on Hyundai vehicles indicates system voltage low. Au7o has documented this code across 6 Hyundai models — most commonly on Entourage, Ioniq 5, Kona. 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. Typical repair costs on Hyundai range from $200 to $1,200, depending on the specific model and root cause.
Common Causes of P0562
- •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
P0562 on Hyundai by Model
Hyundai Entourage(1 issue)
- 3.8L V6 Alternator and Battery Drain Issues2007-2009
The Entourage 3.8L V6 shares the same high alternator failure rate as other Lambda V6 Hyundai vehicles. The alternator fails prematurely between 60,000-80,000 miles. Additionally, the Entourage suffers from parasitic battery drain caused by the power sliding door modules not fully entering sleep mode. This drains the battery overnight if the vehicle sits for more than 2-3 days. The combination of alternator weakness and parasitic drain frequently results in dead batteries and stranded owners.
Hyundai Ioniq 5(1 issue)
- 12V Auxiliary Battery Drain / Dead Battery2022-2025
The Ioniq 5 suffers from 12V auxiliary battery drain, often leaving the vehicle unable to start. The issue is caused by excessive parasitic draw from always-on systems (telematics, Bluelink) and the 12V battery being undersized for the electrical load. The AGM battery used is more sensitive to deep discharge cycles than conventional batteries.
Hyundai Kona(1 issue)
- 12V Auxiliary Battery Repeated Drain and Dead-Car No-Start (Kona Electric)2019-2023
Kona Electric owners across model years report the small 12V auxiliary battery repeatedly draining, sometimes within weeks, leaving the car completely dead and unable to wake the high-voltage system. Because the 12V system must energize before the main pack activates, a flat 12V battery disables door locks, the dash, and the ability to start or charge. Deep discharges (often after dealer software reflashes done without a charger attached) can permanently damage the battery.
Hyundai Palisade(1 issue)
- Repeat 12V Battery Drain from Module Parasitic Draw (Body Control Module)2020-2023
A recurring Palisade complaint is a 12V battery that goes flat after the vehicle sits a few days, repeating even after the battery is replaced — one owner reports being on a fourth battery. The root cause in the documented cases is a module that fails to go to sleep and holds an excessive parasitic draw; the Body Control Module is the culprit most frequently identified on the forums, with the drain disappearing after BCM replacement. Diagnosis is difficult because the Palisade carries 30+ modules and the standard dealer response is to load-test and replace the battery, which does not address the draw. Aftermarket accessories left in the OBD-II port or 12V sockets produce the same symptom and must be ruled out first.
Hyundai Santa Fe(1 issue)
- Premature Alternator Failure2007-2018
Alternators in Santa Fe models fail prematurely, often between 60,000-100,000 miles. The voltage regulator or rectifier diodes fail, causing undercharging, battery drain, and eventually no-start conditions. Some owners report multiple alternator replacements within the vehicle's life.
Hyundai Veracruz(1 issue)
- Alternator Premature Failure and Voltage Regulator Issues2007-2012
The Veracruz 3.8L Lambda V6 has a high alternator failure rate, typically between 60,000-90,000 miles. The internal voltage regulator fails first, causing overcharging or undercharging. Overcharging damages the battery and can blow bulbs, while undercharging causes intermittent electrical problems and eventual no-start. The high electrical demand from the Veracruz's power-everything luxury features (heated seats, navigation, power liftgate) stresses the alternator. The serpentine belt tensioner also wears, causing belt slip that accelerates alternator bearing wear.

What does P0562 mean on Hyundai?▼
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. On Hyundai specifically, this code is documented across 6 models.
What causes P0562 on Hyundai vehicles?▼
Common causes on Hyundai: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0562 on a Hyundai?▼
