Engine overheated and oil pressure low warnings came on suddenly and lost power. I had my two grandkids and was on a dark country road with ditches and no shoulders. Pulled off at the next cross street to get to safety. Was stranded at night in a rural area with my and . Had to have vehicle towed and wait for someone to pick us up.
Vehicle overheated despite coolant level being at max level. I took it to dealer and dealer said it was a faulty thermostat. The problem appeared January 2, 2025, and I immediately took vehicle to the dealer
The component that failed was the thermostat. This failure caused my engine temperature to spike abruptly as I was driving. My safety and my children's safety were put at risk by creating no engine power, undriveable, and was almost hit by cars due to sudden slow down to decrease engine temperature to prevent from over heating.
Two incidences, one week apart, of car turning itself off while stopped at a red light. While stopped at the light, the a sensor flashed and the car automatically shifted from “drive” to “park.” Entire car electrical system shut off.
