While driving my kids to school on the freeway I received an alert telling me that my engine was overheating! I was barely given any warning of the rising temperature to allow myself to pull over safely. It never informed me it was rising, only when it was redlined near the max engine temp to which I had to immediately find a place to pull over. I didn't have enough time to get to the next exit 1 mile away, and had to pull over in an unsafe area and turn the car off until the engine cooled down while cars whizzed by us. Once cooled down enough, I was able to drive 1 mile to the next freeway exit but had to immediately pull over again into a center median as it was again overheating very quickly. My local dealership came to get the car and took my kids to school and me home while they inspected it and found a failing thermostat and water pump. I have only had the vehicle for 9 months and it only has 15,800 miles! This should not happen, at all, on a $135,000 vehicle. I also happened to notice a failing battery (no audio warning of this) on the display while scrolling through the menu looking for the engine temperature! So a brand new car has a failing battery, thermostat and heat pump..... unbelievable.
