What you are looking at

No photograph available

We do not hold a verified photograph for this fault yet. We would rather show none than show a picture of something else.

What goes wrong

The 7-seat Prius Alpha was Toyota's first lithium-ion hybrid (pack in the centre console) while 5-seat versions use NiMH under the rear seat. Both degrade with age, but the Li-ion pack has far fewer refurb options in NZ - most shops quote replacement rather than cell rebalancing, so budget at the top of the range for a 7-seater. Symptoms are the usual red triangle, P0A80-family codes, erratic charge gauge and worsening economy. All factory battery warranties on these cars have expired.

What you would notice

Red triangle with hybrid battery warning
Battery gauge swinging full-to-empty quickly
Fuel economy well above ~5.5 L/100km around town
Engine rarely shutting off

How to check it

Where to look. 7-seat: centre console between front seats; 5-seat: under rear seat

Confirm which pack the car has: 7 seats = Li-ion in the centre console, 5 seats = NiMH under the rear seat - it changes the repair economics.
Watch the charge gauge on a 15-minute test drive for rapid swings, and get a hybrid health report (Dr Prius app or workshop scan) before committing.

What it costs to put right

$1,800 to $5,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Is this the 5-seat (NiMH) or 7-seat (lithium-ion) version?”
“Has the traction battery been replaced or serviced, with invoice?”
