One (or more) of the TPMS sensors on my 2006 Coupe died this spring. It was a slow death. The warning light would be on for a while, then off when the weather warmed up, then back on when the weather turned colder. I checked the tire pressures and they were all correct. Perhaps next time I need new tires I will look into replacing the sensors. I would have preferred to swap out the batteries if I had only known that the sensors were near end of life, but hindsight is indeed 20-20.
