Known Honda GP2 faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
Individual lithium-ion cells within the GP7/GP8 hybrid traction battery develop unequal state-of-charge over accumulated mileage. The battery management system progressively restricts motor assist as cell imbalance worsens, ultimately disabling hybrid drive entirely. Cold weather and high mileage accelerate cell degradation. Grey imports commonly arrive with no documented battery health history, making the fault undetectable without diagnostic scanning of individual cell voltages.
Symptoms to notice
Hybrid or IMA system warning light illuminated on dashboard
Reduced or completely absent electric motor assist at low speeds
Vehicle reverts to petrol-only operation unexpectedly
Hybrid battery charge gauge fluctuating erratically or pinned at one extreme
Noticeable and progressive drop in fuel economy
What to check
Request a hybrid battery diagnostic scan showing individual cell voltages and state-of-charge balance across all modules. Check for stored DTCs P0A7F, P0A80 or similar battery deterioration codes. Confirm whether any hybrid warning lights have appeared in the vehicle's history.
Where to look: Hybrid traction battery pack beneath rear seat cushion
Ask the seller
“Has the hybrid battery pack ever been replaced or reconditioned?”
“Have any hybrid warning lights appeared during ownership?”
“Can you provide a recent OBD scan showing individual battery cell balance data?”
02Rear Torsion Beam Axle Bush Collapse
MinorCommonSuspension $250–$600 to fix
Rear beam axle bushes harden and collapse with age causing handling noise and imprecision. On the Fit Shuttle the rear beam mounts are subject to normal corrosion in NZ conditions.
Symptoms to notice
Knocking or clunking from rear suspension over rough surfaces or speed humps
Vague rear-end handling feel and imprecise directional stability
What to check
Inspect both rear beam mounting bushes for cracking or deformation. Check rear tyre wear for unusual edge wear. If a workshop inspection is possible: Push the beam laterally with vehicle on hoist — any clunking indicates collapsed bushes.
Where to look: Rear beam axle mounting points to body
Ask the seller
“Has the rear torsion beam axle been inspected or repaired?”

Like any used car, it depends on the specific example and its service history. Across the 11 documented faults for the Honda GP2, the recurring problem areas are electrical, transmission, and brakes. A Honda GP2 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 Honda GP2?
+
We've catalogued 11 known faults for the Honda GP2, covering electrical, transmission, and brakes. 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 Honda GP2?
+
Most single repairs on the Honda GP2 fall between $450–$2,200 at NZ independent-workshop rates. Some of the 11 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 Honda GP2?
+
Yes. A Honda GP2 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.
