Known weak points

Curated by Redline from owner club and specialist sources Commonly reported by owners and specialists for the Toyota Prius ZVW30 (2009 to 2015). Not every car has these; check this one.

1. 2ZR-FXE head gasket and coolant loss

   Head gasket failure on the 1.8 is the most reported third generation problem, and it can go unnoticed until it does real damage.

   Where to look

   The coolant reservoir level, the underside of the oil filler cap, and the coolant top up history

   How to test

   With the engine cold, check the coolant is at the mark and ask whether it has needed topping up. Look under the oil cap for white sludge. A rough cold start is a reason for a cooling system pressure test.

   Cost if it needs fixing

   High cost head work, or a replacement engine if left too long

2. EGR cooler and intake carbon

   Carbon from the exhaust gas recirculation system builds up in the EGR cooler and the small ports in the intake manifold, and is linked to faster head gasket failure.

   Where to look

   The EGR cooler and valve at the back of the engine, and the intake manifold

   How to test

   Ask whether the EGR system and intake have ever been cleaned and at what km. Feel for misfires or a shaky idle on the drive.

   Cost if it needs fixing

   Medium cost a thorough clean takes several hours of labour

3. Inverter

   Inverter failures are reported, with Toyota recalling cars over the inverter and still some failing after it. A failure can leave the car without drive.

   Where to look

   The inverter under the bonnet, and the recall record for the VIN

   How to test

   Ask for proof the inverter recall work was done, or have a Toyota dealer check the VIN. Look for hybrid warning lights on the dash.

   Cost if it needs fixing

   High cost a new or refurbished inverter and fitting

4. Electric water pump

   The engine uses an electric water pump, and when it fails the car is stranded.

   Where to look

   The electric water pump at the front of the engine, and invoices for any replacement

   How to test

   Ask whether the pump has been replaced. Watch for the temperature warning or the cooling fan running hard on the drive.

   Cost if it needs fixing

   Medium cost a new pump and fitting

   Sources: torquenews.com (opens in a new tab)

5. Hybrid battery

   Battery life is a concern on older cars, genuine Toyota packs are very expensive and used packs from wreckers are best avoided.

   Where to look

   The hybrid battery behind the rear seat, and the energy display on the dash

   How to test

   Watch the battery gauge on a long drive for very fast charging and draining, and ask for a hybrid health check report.

   Cost if it needs fixing

   High cost a genuine or reconditioned pack

6. Headlamps

   The LED headlamp bulbs are costly and the electrical ballast can fail with age.

   Where to look

   Both headlamps, dipped and main beam

   How to test

   Switch every light on and walk round the car. Do not accept a small discount for a headlamp that does not work.

   Cost if it needs fixing

   Medium cost expensive headlamp parts

7. Electric air conditioning compressor

   The air conditioning compressor runs on its own electric motor, which can wear out on older cars and is costly to replace.

   Where to look

   The air conditioning, run from the dash controls

   How to test

   Run the air conditioning on cold and check it blows cold quickly. Be wary of a seller who says it only needs a regas.

   Cost if it needs fixing

   High cost a replacement electric compressor

   Sources: parkers.co.uk (opens in a new tab)

8. Brake disc corrosion

   Many cars fail inspections on brake disc corrosion more than on wear, because the hybrid system does much of the braking.

   Where to look

   The brake disc faces behind each wheel, especially the rears

   How to test

   Look through the wheels at the disc faces for heavy rust and a deep lip at the edge. Feel for vibration under braking.

   Cost if it needs fixing

   Low cost discs and pads

Service items

• EGR system and intake clean: about every 90,000 miles (about 145,000 km), as Torque News suggests. Carbon here is linked to head gasket failure. (torquenews.com (opens in a new tab))

Questions to ask the seller

• Has the coolant needed topping up, and has the head gasket ever been replaced?
• Has the EGR system been cleaned, and at what km?
• Has the inverter recall been done, and has the inverter ever been replaced?
• Has the hybrid battery been replaced, and is there a battery health report?
• Does the air conditioning blow cold?

New Zealand notes

• Most NZ ZVW30s are Japanese imports. Compare the odometer on the export certificate with the dash.

A ZVW30 suits a buyer who wants a roomy, frugal hatch and will check the coolant level and inverter recall before buying.
