NHTSA Complaint #11385759 — 2014 RAM 1500

AFTER RECEIVING V08/V11 AEM UPDATE NOVEMBER 18TH, 2020 I AM EXPERIENCING AN AVERAGE OF 5-6 MPG LOSS IN FUEL ECONOMY (16.4 MPG MIXED - DOWN FROM 21.5-22 MIXED) AS WELL AS EXPERIENCE SEVERE ACCELERATION LAG. IN TERMS OF HIGHWAY MILEAGE I AM STRUGGLING TO GET 20 MPG. CURRENT ECM: 68306456AI CURRENT TCM: 68234053AH FOLLOWING THE V08 EMISSIONS RECALL, DRIVABILITY HAS BEEN SERIOUSLY REDUCED AND HAS CREATED DANGEROUS THROTTLE LAG AND IMPROPER AUTOMATIC TRANSMISSION GEAR SELECTION. I WOULD SUMMARIZE THESE ISSUES AS TURBO LAG AND IMPROPER SHIFT MAPPING. WHEN ACCELERATING FROM A COMPLETE STOP THERE IS A 2-3 SECOND LAG BEFORE THE VEHICLE BEGINS TO MOVE EVEN IF THE THROTTLE IS FULLY DEPRESSED. IF YOU ARE EXECUTING A RIGHT OR LEFT TURN INTO TRAFFIC OR CROSSING AN INTERSECTION THIS WILL LEAVE YOU EXPOSED TO A "T-BONE" COLLISION. THIS BEHAVIOR IS EVEN MORE PRONOUNCED WHEN THE VEHICLE HAS NOT BEEN RUN (COLD ENGINE). CLIMBING A MODERATE HILL SHORTLY AFTER PULLING OUT OF MY DRIVEWAY FORCES THE DRIVER TO MANUALLY DOWNSHIFT THE AUTOMATIC TRANSMISSION TO FIRST GEAR TO GET ANY FORWARD TRAVEL. AGAIN, THE VEHICLE WILL RAPIDLY ACCELERATE AFTER THE 2-3 SECOND LAG. ONCE RETURNING TO "DRIVE" AT 15-25 MPH THE TRANSMISSION WILL UP-SHIFT SEVERAL GEARS AND THEN BEGIN SLOWING, DROPPING ENGINE RPM TO 1,000, AGAIN FORCING A MANUAL DOWN-SHIFT TO SECOND OR THIRD GEAR TO MAINTAIN SPEED. THE ENGINE PRODUCES ALMOST NO POWER UNTIL THE ENGINE REACHES 2000 RPM. ALL OF THIS BEHAVIOR BEGAN AFTER THE NOTED RECALL. I HAVE CONTACTED A RAM DEALER REGARDING THIS PERFORMANCE AND WAS TOLD THAT THIS IS A COMMON COMPLAINT. THEY MENTIONED THAT THE FACTORY WAS AWARE OF THIS BUT HAS NO REMEDY AVAILABLE."
