It was a hot day today - around 90f, and the car was parked outside. As we were getting ready to leave, I did the remote start. We get in the car about 5 minutes later. Right As I’m about to start the car, it shuts off. I start it up again, and have a high engine temperature warning. Car is now in some sort of emergency mode (can’t even accelerate it up the driveway). I checked the coolant level. It was low, but still above the min line. I filled it up to max. I’ve let the car sit for 5+ hours now, and it still gives me the high engine temperature warning.
Any thoughts on what’s causing this? Is there an easy fix without having to get it towed?
