I’ve had 2006 Prius for 6 years and love it. Hybrid replaced 2 years ago. Runs very well but last week red triangle came on when going around a few curves I wasn’t speeding , so I don’t know what is going on. Sometimes the abs light comes on and I’ve been told I need the sensor replaced. I’ve procrastinated on this, so maybe it’s time. Are these expensive.? Thank you for any help. Charmaine
Check the engine oil level on the dispstick, asap. May or may not be the problem, but good to start with that. Weak 12 volt battery can cause odd things too. Where there's warning lights there'll be trouble codes stored by the car. If dealership (or 3rd party) can read them, should shed more light.
I was low on oil so I added some then had oil changed. The red triangle disappeared. Yay. I’ve got to be more diligent about checking the oil.
