We got our Honda Civic almost four years ago and we've noticed this thing with the tire pressure sensors almost from the beginning. The sensor light for tire pressure will invariably come on at some point. This has been a constant.
It was off for a couple of months and with the cold weather, it went back on again. I've had the tires checked for leaks and our dealership doesn't seem to be concerned about it. But, it's annoying. I'm never sure if there's a pressure problem.
Is this a design flaw in the Honda Civic? Anbody else experience this with their Civic?
