    Help, my car has randomly had the "Triangle of Death" come on and I can drive but acceleration slows. I stop, turn off and back on and the triangle stays on but car drives normal. I usually goes off after I turn off ignition several times but comes on at least once a day! Frustrated, help!

    Most likely your hybrid battery has failed. Trouble lights have fault codes that should be read by an OBD reader to pinpoint the issue.

    That was replaced when I bought the car 5 yrs ago. Just replaced the 12v too. Any other ideas? At my wits end!!

    Did you check your oil level?

    You need to get a OBDII reader and find out what code its tripping. It could be something really simple and cheap to fix. Get the 12v battery checked just to be sure, its a common cause. There's so many things that can trip the triangle.
