NHTSA Complaint #11233983 — 2016 RAM 1500

I TOOK MY ECODIESEL TRUCK TO MY LOCAL FCA DEALERSHIP AND THEY INSTALLED THE APPROVED EMISSION MODIFICATION (AEM). AFTER I RECEIVED MY TRUCK BACK FROM THE DEALERSHIP, THERE WAS A VERY NOTICEABLE INCREASED THROTTLE RESPONSE LAG FROM A STOP. AFTER APPLYING WIDE OPEN THROTTLE (WOT), THE TRUCK WOULD NOT RESPOND FOR 3-4 SECONDS. THE AEM SPECIFICALLY STATES THAT THE "PERFORMANCE" OF THE TRUCK WILL NOT BE IMPACTED; WHICH IS NOT WHAT I PERSONALLY EXPERIENCED. THE THROTTLE RESPONSE LAG POST-AEM INSTALL ALMOST GOT ME INTO TWO ACCIDENTS WHILE TRYING TO TAKE A RIGHT TURN ONTO A HIGHWAY. THIS EXPERIENCE HAS BEEN WELL DOCUMENTED BY OTHER ECODIESEL OWNERS ON INTERNET FORUMS AND VIA YOUTUBE VIDEOS DEMONSTRATING THIS SAFETY ISSUE. FCA FAILED TO DISCLOSE THIS THROTTLE RESPONSE ISSUE; AS A RESULT THEY HAVE CREATED A SAFETY CONCERN FOR THEIR CUSTOMERS, TO INCLUDE MYSELF, POST-AEM INSTALL. I PULLED OUT THE DEALERSHIP LOT EXPECTING A CERTAIN LEVEL OF PERFORMANCE FROM THE TRUCK I KNOW EXTREMELY WELL, BUT WAS QUICKLY SURPRISED TO FIND MYSELF IN A DANGEROUS SITUATION DUE TO THE THROTTLE LAG. AS A RESULT, I HAVE CHANGED MY DAILY DRIVING HABITS TO ACCOUNT FOR THIS SIGNIFICANT REDUCTION IN LOW END PERFORMANCE POST-AEM INSTALL.
