Known Nissan Fuga faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01Y51 Hybrid High-Voltage Battery Cell Imbalance and Degradation
CriticalCommonElectrical $4,000–$12,000 to fix
The Y51 Fuga Hybrid combines a VQ35HR 3.5L V6 with a 50 kW electric motor and a lithium-ion high-voltage battery pack. Individual battery cells degrade at different rates, causing voltage imbalance across the module. The battery management system attempts to compensate but eventually flags faults when cell spread exceeds tolerance. Advanced degradation reduces the pack's ability to accept regenerative charge or supply assist power, increasing fuel consumption and placing additional load on the combustion engine.
Symptoms to notice
Hybrid system warning light illuminated on the instrument cluster, accompanied by reduced or absent electric motor assist during acceleration
Fuel economy measurably worse than factory specification, and the battery state-of-charge indicator fluctuating erratically or dropping suddenly during light driving
What to check
Connect Nissan CONSULT-III Plus or a compatible hybrid scanner and read individual cell voltages across the battery modules — a spread greater than 0.3 V between the highest and lowest cell indicates imbalance requiring pack replacement. Check P3000-series hybrid fault codes. Inspect the battery cooling fan in the boot for blockage or motor failure, as thermal stress accelerates cell degradation.
Where to look: Boot floor beneath the luggage compartment load panel
Ask the seller
“Has the hybrid battery been tested for cell balance or capacity, and are there any outstanding hybrid warning lights?”
“What is the current real-world fuel economy compared to when the car was new?”
02P0420 catalytic converter efficiency fault
MinorCommonEngine $300–$2,500 to fix
The Fuga commonly triggers P0420 catalytic converter efficiency codes as the cats age, causing a check engine light and potential WOF/emissions failure. Aftermarket cats or O2 sensor faults are frequent culprits.
Symptoms to notice
Check engine light with P0420
Slightly reduced fuel economy
Rotten-egg exhaust smell
Failed emissions test
What to check
Scan for P0420/P0430 codes, check for a persistent check engine light, and inspect the catalytic converters and O2 sensors.
Where to look: Exhaust catalytic converters and oxygen sensors
Ask the seller
“Is the check engine light currently on?”
“Any history of catalytic converter codes?”

Like any used car, it depends on the specific example and its service history. Across the 14 documented faults for the Nissan Fuga, the recurring problem areas are electrical, suspension, and transmission. A Nissan Fuga with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.
What are the most common problems with a used Nissan Fuga?
+
We've catalogued 14 known faults for the Nissan Fuga, covering electrical, suspension, and transmission. Two are written out in full on this page. The rest — with the symptoms to notice, what to inspect, and typical repair costs for each — are free once you create an account.
How much do repairs cost on a Nissan Fuga?
+
Most single repairs on the Nissan Fuga fall between $800–$4,000 at NZ independent-workshop rates. Some of the 14 documented faults cost less and a few cost considerably more, and no one car needs them all. Knowing which ones to look for before you view is what lets you negotiate the price down or walk away.
Should I get a pre-purchase inspection on a Nissan Fuga?
+
Yes. A Nissan Fuga inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $17.90 far less than the cost of missing one of the faults on this page.
