NHTSA Complaint #11031929 — 2015 RAM 1500

EXHAUST FUMES FILL CABIN: 2015 4X4 ECODIESEL. WHEN DRIVING IN SLOW TRAFFIC SPEEDS OF LESS THAN 30 MPH OR STOPPED, THE CABIN BECOMES FILLED WITH EXHAUST FUMES. THIS APPEARS TO BE COMING IN THROUGH THE VENTILATION SYSTEM, AS IT IS QUITE NOTICEABLE WHEN IT IS BLOWING DIRECTLY IN YOUR FACE. IT HAS BECOME PROGRESSIVELY WORSE AND STRONGER OVER TIME. WHILE THE TRUCK IS MOVING AT NORMAL HIGHWAY SPEEDS IT IS NOT NOTICED, OR AT LEAST AS COMPARED TO WHAT IS NOTICED WHEN AT LOWER SPEEDS OR WHEN STOPPED. THE FUMES CONTINUE TO INCREASE AND BECOME QUITE HEAVY WHILE OPERATING AT THE SLOWER SPEEDS OR STOPPED. THIS ISSUE HAS BEEN ADDRESSED IN A RECALL (R04) FOR 2014 AND 2015 RAM 4X2 ECODIESELS BUT NOT IN RAM 4X4 ECODIESELS AS OF 10/5/17.
