Fuel & propulsion system
While driving the car it suddenly decelerated and multiple warning errors on electronics, driver assist, braking started going off then the error message of Check Hybrid Turn Engine Off came on. I was able to coast into a parking lot as the car could only go around 5 miles an hour. I turned the care off and on and the Check Hybrid Turn Engine Off remained for the 2 hours it took to have a tow truck come to take the car to a dealer.

The high voltage battery will no longer charge neither from being plugged in to the charger on the wall nor from the buikt in system onboard the car. There are warning lights saying the inverter coolant is low but the reservoir is at the proper level. I suspect the coolant for the Hybrid charging inverter is bad and crystalizes causing blockages in the inverter coolant system. My car refuses to charge for the last 2 years. After a few seconds (about 7-10) the car shuts off the charging system when plugged in. And now that summer heat us here in the South West, it will not even charge from the regenerative braking. The high voltage battery previously would maintain 10-15% charge from the gas engine and regenerative braking. Now it's sitting at 1%. Because the battery is so low the electric motor does not produce power, and the gas engine is under powered on its own. …
