P0562 on Infiniti
System Voltage Low
P0562 on Infiniti vehicles indicates system voltage low. Au7o has documented this code across 1 Infiniti model — most commonly on QX55. 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 Infiniti range from $200 to $600, 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 Infiniti by Model
Infiniti QX55(1 issue)
- Premature 12V Battery Failure / Parasitic Drain (No-Start, Warning Cascade)2022-2023
The 2022 QX55 debut year drew numerous complaints of the 12V battery failing to hold a charge or discharging prematurely, leaving the vehicle with a no-crank/no-start condition, key-detection errors and a cascade of dashboard warning messages at startup. In one reported case a battery-related electrical failure led to a sudden loss of power steering assist, a serious safety concern. Parasitic draw from the vehicle's electronics and short-trip driving accelerate the problem.
