P0A94 - C1203 -C1259 - C1310 -C1345 - C1336 - C1392

Hi all,

I have a 120k ZVW30 2012 Prius.


I was doing online research about my dead Prius. It stopped working the other day all of a sudden. The engine power cut off after it skitted on a heavy rainy day.


The 12v battery fits perfectly, and I also recharged it at home.


The dashboard lights turn on, but the gasoline engine doesn't start, and the vehicle won't shift into Drive or Reverse.


I can hear the power cutting off when I hit the start button with the brake pedal. I have this error on my dashboard screen “ Hybrid system check, Please stop in a safe place. “


I was recalled from Toyota Dealer in Christchurch, New Zealand, in 2021.

Are you guys aware of any recalls or warranties that might cover this?


It would be greatly appreciated if you could help.
Cheers!

Hi there, Chapman.
Thanks for taking the time to share your thoughts; any little bits and pieces of information help!

One of the mechanics here in New Zealand said the same thing about the error codes. P0A94 will kick off deferred faults for the other systems, such as the brake system and sensors. I replaced the 5 AMP mini blade fuse last night, but with no luck.

My car was recalled in 2021; this is likely related, but there was no fault then.

I'll contact the official Toyota dealership in Christchurch to confirm what repairs or inspections they performed during the recall. If the recall was P0A94 related, it might only cost me a tow truck.

 

Toyota Prius and Prius V hybrid recall
12 October 2018 / Recalls

Toyota New Zealand is recalling 1,169 vehicles due to a concern with the fail safe mode in the hybrid system. The impacted models are Prius and Prius V hybrids manufactured between the 23rd January 2009 to 30th June 2014.

This is a precautionary recall due to the possibility, that in the event of an internal component failure, the hybrid system could shut down instead of going to into fail safe mode. This could result in the vehicle losing power while driving, increasing the risk of an accident.

There are 1003 Prius, and 166 Prius V hybrid New Zealand new vehicle models affected.

The remedy will be completed free of charge by Toyota stores and will take approximately 40 minutes to complete.

Owners of the vehicles, which are traceable through registration data, will be contacted by Toyota New Zealand through a remedy owner letter.

Toyota advises that a number of its 3rd generation Prius vehicles are subject to a recall relating to the Electronic Control Unit.

The recall affects 1003 Prius vehicles sold new in New Zealand, manufactured between March 2009 and February 2014.

In affected vehicles the fault is a potential Electronic Control Unit (ECU) malfunction due to high operating environment temperatures.

If increased thermal stress occurs, damage could be caused. This would result in illumination of warning lights on the instrument panel. In most cases the vehicle would enter a fail-safe mode, resulting in reduced power. In limited instances, it is possible the system could shut down resulting in the vehicle stopping.

Toyota New Zealand General Manager of Customer Services Spencer Morris says the recalls are precautionary. There have been no reported instances of ECU failure in New Zealand related to this condition.

"Instances in New Zealand are extremely unlikely because New Zealand conditions mean engines don’t generally reach operating temperatures where this could be an issue."

The required software upgrade to remedy the condition is being undertaken immediately however.

"Owners of vehicles affected will receive a notification letter and are advised to contact their Toyota dealer." says Mr Morris. "The remedial action will take approximately one hour, and will be free of charge to customers."

Toyota New Zealand’s safety policy is to support all Toyota vehicles regardless of importing channel, Mr Morris says, so used imports brought to our attention would also receive the upgrade if required.



The article states: "Instances in New Zealand are extremely unlikely because New Zealand conditions mean engines don’t generally reach operating temperatures where this could be an issue."

However, it was scorching hot here in Christchurch for about two weeks. This might have caused the issue.

 

it was scorching hot here in Christchurch for about two weeks. The temperatures were above historically recorded data, with mostly record-hot days.

The ozone hole does not significantly affect the ozone concentration in New Zealand; bear in mind we barely have an ozone layer here.

It felt 40 degrees and above under direct sunlight, possibly related to the hot weather. This might have caused the issue.

 

Hi all,
It has been a long journey; however, this has been honoured free of charge via Ilam Toyota Christchurch.

Good bye!
