NHTSA Complaint #11253119 — 2015 RAM 1500

AFTER THE AEM UPDATE RELATED TO THE ECO DIESEL EMISSIONS SETTLEMENT, THE TRUCK HAS A DANGEROUS THROTTLE LAG, ESPECIALLY AT COLD START. I HAVE PULLED OUT NUMEROUS TIMES ONLY TO HAVE ESSENTIALLY NO RESPONSE BEFORE A VEHICLE COMES ALONG AT HIGHWAY SPEED. I CAN PUT THE PEDAL ON THE FLOOR AND IT CAN TAKE SEVERAL SECONDS BEFORE THE TRUCK FINALLY STARTS TO ACCELERATE. THIS HAPPENS WITH AN EMPTY TRUCK BUT IS EVEN MORE DANGEROUS WHEN TOWING. I AM NOT SURE HOW MUCH OF THIS IS THROTTLE RESPONSE, TRANSMISSION OR TURBO LAG BUT IT IS A SCARY FEELING TO NOT BE ABLE TO MERGE NORMALLY INTO TRAFFIC. I RETURNED TO THE DEALER AND THEY TRIED A REFLASH OF THE COMPUTER TO ADJUST THE ACCELERATOR POSITION SENSOR. I THOUGHT IT WAS A LITTLE BETTER FOR A SHORT PERIOD BUT IT IS AS BAD AS EVER.
