    Today, I got the Triangle of Death on the HWY, while doing 75mph    :(

    I got all kinds of warning lights including= BRAKE WARNING , ABS WARNING, VSC WARNING,
    CHECK ENGINE WARNING &= the A/C stopped working.

    --I was able to make it home 20 miles away

    BUT??==I still had all the BLUE BARS on the charging system, with the Triangle of Death on the dash?

    ***SEE THE 2 DASH PICTURES I POSTED
    Any suggestions?

    For me these were the symptoms of P0A93, or failed inverter pump. You only get it when the car runs long enough for the inverter temperature to hit about 180 degrees F.

    Get a capable scantool and check all systems for codes.

    It certainly could be a P0A93 inverter overheat, but that's a guess. I suppose you could check the inverter coolant reservoir for agitation and circulation.

    My code reader says= P0A93, a failed inverter pump
    ***Buying an OEM' inverter pump' at the dealer tomorrow.
    Going to attempt to change it out myself.

    When swapping it out remove the drivers headlight. The job is so much easier when you do. And you can reuse the mounting bracket and just pinch off the hoses and you wont have to drain or loose much coolant.

    When the inverter gets too hot, it's programmed to turn off functions (like A/C) to protect itself - it'll be fine.

    Bro, I drove my white-hot inverter for about that distance. I believe the car dials back power under P0A93 so you can't do too much damage. Check out what my old pump looked like..
