Toyota corolla hybrid shutting down while stopped in traffic

Bricriu

I've have had a Toyota Corolla hybrid (2019) for a while, and its engine has shut down twice while stopped in traffic, and I was stuck for about 5 minutes trying to get it restarted.

Anyone know why this is happening? Both times it has happened, it has happened shortly after starting to drive the car (cold engine).

The panel gives an instruction to place car in 'P' (Parking Mode), but doing that several times doesn't seem to help.

its meant to stop in traffic, you ignore it, when the traffic moves you take your foot off the brake and accelerate, if the traffic is slow it might not start for a few kms, battery is full, no need to have the engine running if your not moving and not charging,

It will run till the engine is warm, then it will decide to start and stop on its own accord, even if you turn it off and on, the car will not start the engine.

Now if you already know that, then its talk to a mechanic time, something else is wrong.

Sounds like normal operation for a Hybrid OP. Engine never runs when stationary, only during warm up phase. Once you've got the word "Ready" lit up green on the instruments then you're good to go

Miscreant

@Bricriu has had the car for a while so I imagine they know how it behaves.

The petrol engine should come on once you have reached a certain speed or demand too much power from the electric motor. When pulling away from a traffic light, I would not expect the petrol engine to come on immediately unless you are really on the throttle. I had an Auris Hybrid for 8 years and could force the engine to come on by using B mode on the gear selector or ramping the cabin temperature on the AC to something ridiculous like 29c, while stationary. You can also get the petrol engine to come on by putting the car in PARK and stepping on the accelerator about half way. The engine will come on for a few seconds and can be kept on by maintaining the accelerator (this is a way to measure emissions for the petrol engine and is a type of "diagnostic" mode).

Failing all that and the engine is still not coming on then you need to get the car checked out. It could be something simple like the 12v battery being low, or on it's way out, but you would have seen other evidence of this before now (and I believe the 12v charges from the larger traction battery anyway).
