Known Toyota Voxy faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01ZWR80 Hybrid MG2 Transaxle P3190 Traction Fault
CriticalOccasionalElectrical $3,500–$13,000 to fix
The ZWR80 hybrid transaxle houses Motor Generator 2 (MG2), which provides primary drive torque to the front wheels. Degradation of MG2 resolver sensor accuracy, motor winding insulation breakdown, or inverter IGBT gate drive faults triggers DTC P3190 (HV motor power supply fault) and related codes P3175, P3125, or P0A1A. The dashboard illuminates the red hybrid system warning triangle and in most cases disables EV drive mode, forcing the ICE to run continuously. In severe cases the hybrid system enters failsafe limp mode limiting vehicle speed to approximately 40 km/h. High-mileage units over 180,000 km imported from Japanese taxi or commercial fleets carry elevated risk. Repair requires Toyota dealer-level Techstream diagnostics to isolate the fault to the resolver, inverter, or motor assembly before committing to transaxle replacement.
Symptoms to notice
Red hybrid system warning triangle on instrument cluster
Traction control (TRAC) warning light
Loss of EV drive mode — engine runs continuously
Reduced power limp mode, vehicle limited to approx 40 km/h
P3190, P3175, or P0A1A OBD fault codes on hybrid scanner
What to check
Request a Toyota Techstream or Autel hybrid-capable scan of the hybrid ECU — a basic OBD reader will not access P3190. Test drive under load including EV mode engagement. Check the hybrid battery state-of-health percentage. Inspect HV coolant level in the inverter coolant reservoir. Verify odometer authenticity against service records for high-mileage import risk.
Where to look: Hybrid transaxle beneath the engine — MG2 motor is integrated into the transaxle housing on the front axle
Ask the seller
“Has the hybrid warning triangle ever illuminated?”
“Has the vehicle been to a Toyota dealer for any hybrid system diagnosis or repair?”
“What is the high-voltage battery state-of-health percentage?”
“What is the documented import odometer history and source fleet (taxi, private)?”
02Electric Power Steering Rack Knock and Rattle
MinorCommonSuspension $300–$1,800 to fix
Noah models of both ZRR70 and ZRR80 generations use an electric power steering (EPS) rack. A known failure mode is the development of a knock or rattle from the steering rack over road imperfections, caused by internal wear in the rack housing, worn tie-rod end sockets, or loosening of the EPS motor mount to the rack body. The rattle is distinct from suspension noise — it transmits directly through the steering column and is most evident at low speed over rough surfaces. In some cases the EPS motor drive gear or intermediate shaft splines develop lash, producing a knock on initial steering input from centre. Early intervention with tie-rod replacement or rack mount tightening can arrest the fault; a worn rack housing requires full rack replacement.
Symptoms to notice
Clunking or rattling noise from the steering rack area when driving over potholes or road joints
Knock felt through the steering wheel rim when hitting a bump while cornering
Loose or notchy feeling on-centre in the steering with slight free play before effort builds
Drive slowly over a speed bump or rough road surface and listen for a knock or rattle that coincides with steering wheel vibration. With the vehicle stationary, have a second person sharply turn the wheel left and right while you listen under the bonnet for clunking from the rack or intermediate shaft. Check for free play in the steering by gently rocking the wheel left and right — more than 10 mm of play at the rim before the rack moves indicates internal wear. Inspect tie-rod ends for play by gripping and attempting to move them with the wheel straight.
Where to look: Steering rack behind front subframe, EPS motor on rack body, intermediate steering shaft
Ask the seller
“Is there any knock or rattle from the steering when going over bumps?”
“Has the steering rack, tie-rod ends, or EPS components been serviced or replaced?”
“Does the steering feel tight and direct with no free play on-centre?”

Like any used car, it depends on the specific example and its service history. Across the 32 documented faults for the Toyota Voxy, the recurring problem areas are electrical, cooling, and suspension. A Toyota Voxy 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 Toyota Voxy?
+
We've catalogued 32 known faults for the Toyota Voxy, covering electrical, cooling, and suspension. 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 Toyota Voxy?
+
Most single repairs on the Toyota Voxy fall between $450–$1,800 at NZ independent-workshop rates. Some of the 32 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 Toyota Voxy?
+
Yes. A Toyota Voxy 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.
