What 136 owners told NHTSA about the 2015 Ram 3500

THE TUCK HAS A HORRIBLE LAG IN THE THROTTLE RESPONSE. WHEN TRYING TO PULL OUT INTO HEAVY TRAFFIC THE TRUCK LAGS MORE THAN IT SHOULD. THIS HAS BEEN HAPPENING SINCE THE DAY I BOUGHT IT NEW WITH 16 MILES ON IT. IF YOU PRESS THE PEDAL MORE THAN HALF DOWN FROM A STOP YOU CAN COUNT TO 30 BEFORE IT ACTUALLY STARTS MOVING. THERE HAVE BEEN MULTIPLE TIMES WHERE THIS HAS ALMOST CAUSED AN ACCIDENT. I HAVE BEEN READING FORUMS ABOUT THIS ISSUES AND HAVE COME UP WITH 2 CAUSES. 1 THE THROTTLE CONTROL PROGRAMING IS SET EXTREMELY CONSERVATIVE WHICH WILL CAUSE THIS. 2 THE ONE THAT ALMOST EVERYONE IS REPORTING IS THAT THE DPF REGEN SYSTEM IS CAUSING TOO MUCH BACK PRESSURE. PEOPLE ARE REPORTING THAT WHEN THEY DELETE THE EXHAUST AND EGR OFF THE TRUCK IT GETS ITS POWER BACK. THESE SYSTEMS NEVER SEEM TO COMPLETELY CLEAN OUT AND ALL WISE HAS HIGH BACK PRESSURE.

2015 RAM 3500 LARAMIE DUALLY 4X4, 6.7 I6 CUMMINS, AISIN TRANSMISSION. TRUCK EXPERIENCES "DEAD PEDAL" UNDER HARD ACCELERATION OR WHEN DEPRESSING PEDAL 3/4 TO FULL THROTTLE SUDDENLY. THIS HAPPENS UNDER ALL CONDITIONS: STOPPED, ROLLING, UNDER ACCELERATION. ADVANCING THE PEDAL SUDDENLY OR COMPLETELY DOWN IN EMERGENCY SITUATIONS RESULTS IN A 3-4 SECOND DELAY WHERE THE TRUCK WILL NOT RESPOND, THEN SLOWLY ADDS POWER. THIS IS EXTREMELY DANGEROUS AS THE TRUCK WILL NOT RESPOND TO THE DRIVERS INPUTS. POSSIBLY RESULTING IN A CRASH OR DEATH. IN SEVERAL CASES THE TRUCK HAS RESPONDED IN THE ABOVE DESCRIBED MANOR RESULTING IN EMERGENCY ACTION BY THE DRIVER TO AVOID A CRASH OR WRECK. PROBLEM HAS BEEN OCCURRING FOR THE PAST 10 - 15K MILES AND STILL CONTINUES. AS PER THE DEALER SERVICING THE VEHICLE. WE WERE TOLD NOTHING IS WRONG, THIS WAS NORMAL AND THEY REFUSED TO DO ANYTHING ABOUT IT. AS PER RAM TECHNICAL ASSISTANCE "IF THE CUSTOMER STEPS IN THE THROTTLE, THE VEHICLE WILL GO INTO DERATE TO KEEP THE DRIVESHAFT OFF THE GROUND. IF YOU STAY AROUND 60 TO 70% THROTTLE THEN THERE IS NO DERATE. SOUNDS LIKE THE VEHICLE IS OPERATING AS DESIGNED." A COPY OF THE REPORT HAS BEEN PROVIDED WITH THIS REPORT

THE NEW DODGE RAM EQUIPPED WITH CUMMINS DIESEL EXPERIENCE A DEAD PEDAL, OR PEDAL DELAY WHEN PRESSING THE GAS PEDAL 3/4 TO FULL THROTTLE. THIS POSES A SERIOUS RISK WHEN NEEDING TO GET OUT OF THE WAY, OR MOVE THE VEHICLE UNDER EMERGENCY CIRCUMSTANCES. THIS HAPPENS UNDER ALL CONDITIONS: STOPPED, ROLLING, UNDER ACCELERATION ETC. IF YOU PUSH THE PEDAL TOO FAR THE TRUCK WILL NOT RESPOND TO OPERATOR COMMANDS AND WILL TAKE 1.5-2 SECONDS TO START PICKING UP SPEED. THIS IS A SERIOUSLY DANGEROUS SITUATION AND SOMEONE IS GOING TO GET KILLED OR SERIOUSLY INJURED. THERE IS NOT EXCUSE FOR A VEHICLE NOT RESPONDING TO DRIVER INPUT. MANUFACTURE CLAIMS "TURBO LAG", THIS IS SIMPLY NOT TRUE. YOU CAN BUILD TURBO BOOST, MONITORED ON THE VEHICLE GAUGE, THEN PRESS THE PEDAL TO THE FLOOR, THE TRUCK WILL NOT RESPOND FOR 1.5 TO 2 SECONDS. PLEASE LOOK AT FURTHER INFORMATION ON THE CUMMINS FORUM BELOW, IT HAS NUMEROUS ARTICLES ABOUT THIS ISSUE. HERE AS A LINK TO JUST ONE OF THEM. HTTP://WWW.CUMMINSFORUM.COM/FORUM/2013-GENERAL-DISCUSSION/1836593-VERY-SLOW-THROTTLE-RESPONSE.HTML PLEASE, HELP FIX THIS ISSUE BEFORE SOMEONE GETS HURT OR KILLED DUE TO THE INABILITY TO MOVE THE VEHICLE OUT OF HARMS WAY. THIS TSB SOMEWHAT ADDRESSES THE PROBLEM, BUT ONLY FIXES IT PARTIALLY, NOT TO THE POINT THAT IT IS SAFE. TSB 18-041-15 I BELIEVE THE MANUFACTURE KNOWS THIS IS AN ISSUE, BUT IS NOT FIXING IT DUE TO EMISSIONS RELATED PROGRAMMING ON THE VEHICLE. THERE ARE AFTERMARKET SOLUTIONS TO THIS PROBLEM, HOWEVER THEY VOID THE MANUFACTURE WARRANTY, AND IM NOT WILLING TO LOSE MY WARRANTY ON A NEW VEHICLE. I WILL BE SUBMITTING ANOTHER ONE OF THESE FOR MY 2015 AS WELL, SINCE THEY BOTH HAVE THE SAME ISSUE. THANK YOU. *TR

THE TRANSMISSION IS SEVERELY LIMITED BY TORQUE MANAGEMENT. IF YOU STEP ON THE GAS PEDAL THE TRUCK BARELY MOVES. IT MOVES AT ITS OWN PACE INSTEAD OF BEING UNDER YOUR CONTROL. THIS CAN CREATES SOME VERY DANGEROUS MERGING SITUATIONS WHERE YOU ARE TRYING TO MERGE WITH TRAFFIC AND THE TRUCK DECIDES IT WON'T MOVE. YOU END UP HALF WAY COMMITTED AND HALF WAY NOT.
