If your car says that when you're starting it at your home then it may not be something to be concerned about but if that message pops up immediately after you hit something at highway speeds, you should take that as an indication something is definitely wrong and pull over. I had a similar innocuous sounding message popup in my car (not Tesla) right after there was significant damage to the tires/rims and suspension due to some large debris on the road. I pulled over immediately but the car's "Car needs service"/"Tire pressure low" messages were ironically amusing when I got out and saw the extent of the damage (completely flat tires, broken rims, etc). TLDR: Cars don't have "This car will explode/catch fire" messages. "Needs service" message can mean something really bad.
