NHTSA Complaint #11338568 — 2019 RAM 2500

I HAVE THE FACTORY REAR AIR SUSPENSION, AND FOR THE MOST PART, IT WORKS VERY WELL. THERE ARE A COUPE OF SERIOUS SAFETY ISSUES THAT I BELIEVE COULD EASILY BE RESOLVED WITH A LITTLE PROGRAMMING. WITH THE FACTORY AIR SUSPENSION, IT AUTO-LEVELS. THIS MEANS YOU CAN NO LONGER USE HOW MUCH THE TRUCK SUSPENSION SQUATS TO GAUGE THE LOAD THAT THE TRUCK IS CARRYING. IT IS IMPORTANT TO BE ABLE TO GAUGE THE AMOUNT OF WEIGHT THE TRUCK IS CARRYING, ESPECIALLY WHEN LOADING A TRAILER (SUCH AS A PIECE OF EQUIPMENT ON THE TRAILER), SO THAT THE COMBINATION CAN BE SAFELY DRIVEN AND HANDLE WELL. THE ONLY INDICATION OF THE WEIGHT IS WHEN THE TRUCK REPORTS "AIR SUSPENSION DISABLE DUE TO PAYLOAD". THIS ISSUE COULD BE EASILY SOLVED WITH A LITTLE PROGRAMMING TO SHOW THE DRIVER THE PRESSURE IN THE REAR AIR BAGS ON THE UCONNECT/STEERING WHEEL DISPLAY. THE OTHER ISSUES COMES FROM WHEN THE "AIR SUSPENSION DISABLE DUE TO PAYLOAD" MESSAGE HAS BEEN ACTIVATED. ONCE ACTIVATED, THE ONLY WAY TO RESTORE THE AIR SUSPENSION FUNCTION IS TO DRIVE AT OR ABOVE 14MPH. THIS SHOULD BE ABLE TO BE RESET BY THE DRIVER, AND WITH THE VEHICLE STATIONARY. IF YOU TRY TO UNHOOK A TRAILER THAT HAS SET THIS MESSAGE, EVEN AFTER THE LOAD HAS BEEN REMOVED, YOU HAVE TO JACK THE TRAILER EXCESSIVELY HIGH AS THE AIR SUSPENSION DOES NOT AUTO-LEVEL AND WILL KEEP RAISING UNTIL THE AIR BAG TRAVEL MAXES OUT. ONCE DRIVING THE VEHICLE TO RESET THE SUSPENSION AND TRYING TO RE-HOOK THE TRAILER, YOU RUN OUT OF JACK BEFORE THE TRAILER SITS ON THE TRUCK BALL AT IT'S NORMAL AUTO-LEVEL RIDE HEIGHT. THIS CAUSES A NUMBER OF SAFETY ISSUES WHEN TRYING TO RE-HITCH. PLEASE LOOK INTO THESE SAFETY ISSUES WITH THE AUTO-LEVEL SUSPENSION OF THE RAM, AS I BELIEVE BOTH ARE EASILY SOLVABLE WITH NOTHING MORE THAN A SOFTWARE UPDATE. I HAVE HAD THIS HAPPEN SEVERAL TIMES, AND IT'S TROUBLING THAT IT CANNOT BE RESET WITH THE TRUCK STATIONARY.
