P0562 on Hyundai
System Voltage Low
P0562 on Hyundai vehicles indicates system voltage low. Au7o has documented this code across 2 Hyundai models — most commonly on Entourage, Veracruz. 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 $700, 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 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.
