My tire light has been on for well over a year now.
I had a slow leak, and during that time (many months, definitely longer than recommended), I would wait for the light to come on, fill the tire, and go on my way. I finally went in and got the tire repaired. Easy.
Except of course it wasn't. When I picked up the car at the tire shop, they let me know that the light would go off within a few miles. It didn't. I brought the car back. They checked the tire, checked the light, and told me that it would, eventually, go off.
It didn't. They checked again, and finally told me it was probably the sensor. The tires were fine.
And I've been driving a car with a tire light on ever since. It drove me crazy for a while, but now I'm used to it. I check the pressure every once in a while, I know it's fine, and I just...deal. It's not a problem.
Except that when I have people in the car, I feel like I'm embracing my inner Penny from the Big Bang Theory. Yes, I know the light is on. I can see it. But it's fine.
In fact, I'm totally used to my car's idiosyncrasies by now, and it probably looks bizarre from the outside. For example, my car has a slow oil leak. When my check engine light comes on, it usually means the car is low on oil (I'm sure it would make more sense for the oil light to come on, but it doesn't). I'm completely blase about it.
On the other end of the spectrum, my friend just traded in her car for a new model, because her check engine light was on. She got the car serviced, but the light didn't go off immediately, and she didn't like it. She didn't feel confident driving the car.
Whereas right now, I'm happy in my denial, that my ten year old, nearly 200K miles old car will hang in there until my ideal car goes on sale, no matter how many lights flash up at me.
