P0562 on Nissan by model: symptoms, diagnosis and fix
A number of late-production 370Z owners report weak-battery and intermittent no-start complaints, especially on low-mileage cars that sit for extended periods. The problem is often not a major module failure but a marginal factory battery, storage-related sulfation, or parasitic draw from accessories/dashcams after the car sits. Symptoms can mimic starter or clutch-switch faults, but voltage testing usually reveals a weak battery state.
Common Symptoms
- Slow crank or single click on startup
- Intermittent no-start after sitting
- Battery repeatedly needs jump-starts
- Low voltage warnings or dim interior lights
How to Fix
Load-test the battery, check resting and cranking voltage, and verify charging-system output. If the battery fails testing or is original and aged, replace it with a quality AGM or OEM-spec unit and clean/tighten terminals. If discharge continues, perform a parasitic draw test after modules go to sleep and isolate any aftermarket accessory load.
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.
A recurring owner complaint on newer Sentras involves weak factory batteries, hard starting, no-start conditions, or stalling/rough restart behavior associated with the idle stop/start system. The problem often appears early in ownership and may be aggravated by short-trip driving or battery state-of-charge issues. In some cases, owners report multiple jump-starts or battery replacement within the first few years.
Common Symptoms
- Slow cranking
- No-start condition
- Vehicle needs jump-start
- Engine stalls or restarts roughly at a stop
- Auto start-stop unavailable warning
- Battery warning messages
How to Fix
Load-test the 12V battery, verify charging-system output, and check for excessive parasitic draw or battery sensor issues. If the battery fails testing or repeatedly drops below specification, replacement with the correct AGM/EFB type and battery registration/reset procedures may be required. Owners who experience repeated stop/start-related events should have the system scanned for BCM/ECM faults and software updates.
Owner tips & cautions
- TipHave the battery tested with a proper conductance/load tester rather than relying on voltage alone; many weak batteries still show acceptable resting voltage.
- TipIf you mostly drive short trips, use a smart maintainer periodically to keep the battery fully charged and reduce stop/start-related low-voltage issues.
The Leaf's small 12V auxiliary battery drains and fails frequently, sometimes within 2-3 years. The telematics system, Carwings/NissanConnect, and other modules draw power even when the car is off. If the 12V dies, the car cannot be turned on despite the traction battery being fully charged. This is the #1 most-reported issue on Leaf owner forums across all model years.
Common Symptoms
- Car won't power on despite traction battery charged
- No response from key fob
- Dashboard lights dim or flickering
- Clock resets to wrong time
- Car dies after sitting for a week
How to Fix
Replace the 12V battery proactively every 3-4 years ($100-$180 for the correct Group 51R battery). The battery is under the hood. Disconnect the 12V negative terminal if the car will sit unused for more than 2 weeks. A trickle charger ($25-$40) connected to the 12V keeps it topped off during storage. If stranded, jump-start the 12V with a portable jump pack to restore the vehicle to operation.
What you need to fix it
Only diagnosis- and fitment-reviewed repair parts are linked here.
- Genuine Nissan Group 51R battery 999M1-NB51R
Confirm model year, terminals, physical group size and VIN with the selling dealer before pickup.
- CTEK MXS 5.0 NA 12-volt battery charger and maintainer
Confirm the installed LEAF 12V battery chemistry and follow Nissan/CTEK connection guidance; never connect it to the traction battery.

Owner tips & cautions
- TipMark your calendar to replace the 12V every 3 years. Keep a lithium jump pack in the frunk. The Leaf's 12V dies more often than any car I've owned because of the always-on telematics draining it.

Frequently asked questions
What does P0562 mean on a Nissan?
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 Nissan it is documented across 3 models: 370Z, Sentra, Leaf.
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 Nissan?
Published repair estimates on Nissan range from $100 to $700 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.
