Toyota C-HR: 2ZR-FXE Hybrid Traction Battery Cell Failure
2ZR-FXE Hybrid Traction Battery Cell Failure is a common electrical fault on the Toyota C-HR on the 2016 onward cars, and we rate it major. Putting it right costs $2,800 to $8,500 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 17 documented faults on the Toyota C-HR.

What goes wrong
High-voltage NiMH traction battery packs on the 1.8 hybrid C-HR develop cell imbalance and capacity loss from around 8–10 years or 120,000 km. Individual module failure causes the hybrid system to enter limp mode or shut down entirely. JDM imports arriving in NZ at 5–7 years old can reach this threshold rapidly. Reconditioned packs using pulled Prius cells are the usual repair path; new OEM packs are expensive and often unavailable locally.
What you would notice
- Red triangle warning light on dash
- READY light fails to illuminate after start sequence
- Significantly reduced fuel economy
- Hybrid system shuts down mid-drive
- Battery charge bars fluctuate wildly on MID display
How to check it
Where to look. Under rear seat squab, full-width traction battery assembly
Request a hybrid battery health scan (Toyota Techstream or compatible OBD tool that reads block voltages).
Check for stored P0A80 or P3000-series DTCs.
Compare individual cell block voltages — a spread greater than 0.3V between blocks indicates failing modules.
What it costs to put right
$2,800 to $8,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Has the hybrid battery ever been tested or replaced?”
- “How many kilometres has the vehicle covered since new?”
- “Is there any current hybrid system warning on the dash?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.

Toyota C-HR buyer questions
Is 2zr-fxe hybrid traction battery cell failure serious on a Toyota C-HR?
We rate it major and common on the Toyota C-HR. High-voltage NiMH traction battery packs on the 1.8 hybrid C-HR develop cell imbalance and capacity loss from around 8–10 years or 120,000 km. Individual module failure causes the hybrid system to enter limp mode or shut down entirely. JDM imports arriving in NZ at 5–7 years old can reach this threshold rapidly. Reconditioned packs using pulled Prius cells are the usual repair path; new OEM packs are expensive and often unavailable locally.
How much does it cost to fix on a Toyota C-HR?
$2,800 to $8,500 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Toyota C-HR years are affected?
Our research records this fault on the 2016 onward Toyota C-HR. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
How do I check for it before I buy?
Request a hybrid battery health scan (Toyota Techstream or compatible OBD tool that reads block voltages). Check for stored P0A80 or P3000-series DTCs. Compare individual cell block voltages — a spread greater than 0.3V between blocks indicates failing modules. Look here: Under rear seat squab, full-width traction battery assembly
