P0562 on Infiniti by model: symptoms, diagnosis and fix
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.
Common Symptoms
- No-crank / no-start, clicking on start
- Multiple dashboard warning messages at startup
- Key/fob not detected
- Dim or flickering interior/dash lights
- Battery repeatedly dead after sitting
- Reported loss of power steering assist with electrical failure
How to Fix
Load-test the battery and charging system; replace with a correct OEM-spec Group 35/AGM battery if degraded. If the battery drains while parked, perform a parasitic-draw test to isolate a module (infotainment/telematics) staying awake. Reprogram/replace the battery and register it if the system requires. Address any charging (alternator) fault and keep the battery topped up on a maintainer during long storage.

Frequently asked questions
What does P0562 mean on a Infiniti?
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 Infiniti it is documented across 1 model: QX55.
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 on a Infiniti?
Published repair estimates on Infiniti range from $200 to $600 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
