Beginning the day I bought the car, the check tire pressure light has come on at least 2-3 times a month. I have brought the car into a Honda dealer for service each time to check tire pressure, which has 98% of the time been fine. They have done 2 computer software upgrades, the first of which seemed to help for a few months, but then it came back on; the 2nd time it was upgraded, the light came back on the next day. I recently left the car at the dealer for 8 hours and they found nothing wrong with it, but said the problem was a small discrepancy in the tread of the tires - one tire had 4/32 of a tread and the others had 5/32. However, since the light has been on since the day I bought the car and the tires were then new, this is obviously not the problem. In other words, they have no explanation and no fix for the problem. This is very frustrating and produces a lot of anxiety because I don't know if there is a problem with my tire or not. I have learned to just disregard the warning light, but being an elderly woman who drives long distances once a month, it produces a lot of anxiety and worry.
