Ever since I got my bike out for the first ride this spring the TPMS light has been coming on. Let me explain: I ride for 8 or 9 miles and the TPMS light comes on, ride another 4 or 5 and the light goes back off and stays off rest of day/ride, this happens every time I take a ride. Bike is a 2012 Level 3 Goldwing, purchased in May 2011, TPMS sending units in tires have never been changed. I hope Fred sees this and has some idea of what the problem might be. I could believe the batteries are probably getting bad, but if that's the problem why would the light turn off and stay off until the next time I take a ride?
