NHTSA Complaint #11065370 — 2014 RAM 2500

TPMS SYSTEM. FACTORY SET TIRE PRESSURE FOR FRONT IS 60PSI, AND 80PSI FOR THE REAR TIRES. WHEN WINTER ARRIVES I PUT ON SNOW TIRES AND DECREASE THE PSI FOR BETTER AND SAFER DRIVING. FOR WINTER DRIVING WITH SNOW AND ICY CONDITIONS I RUN 45 PSI IN THE FRONT AND 50 PSI IN THE REAR. THE TPMS ACTIVATES A 'TROUBLE LIGHT' IN THE HUD. I CAN LIVE WITH THE BASIC THEORY BUT AM CONCERNED IF ANY TIRE ACTUALLY LOST PSI (DUE TO A TIRE MALFUNCTION) THAT I AND MY FAMILY COULD BE ENDANGERED SINCE THE HUD WOULD NOT NECESSARILY CHANGE. I HAVE HEARD THAT THROUGH THE ECM THE SYSTEM CAN BE PROGRAMED TO REFLECT LOWER PSI. THIS IS AN AFTERMARKET DEVICE. SOME DEALERSHIPS ARE SAID TO REPROGRAM THE SYSTEM TO ACCEPT LOWER AIR PRESSURE FOR A FEE. THIS IS A DEFINITE SAFETY ISSUE AND SHOULD NOT CAUSE A FINANCIAL BURDER ON THE OWNER OF THE VEHICLE. THIS TPMS ISSUE EFFECT NUMEROUS VEHICLES THAT OPERATE IN A 4 SEASON ENVIRONMENT. THE DATE FOR "WHEN DID THIS HAPPEN" IS ADJUSTABLE AS TO WHEN THE OWNER CHANGES OVER TO WINTER TIRES.
