“I receive several recall notices on EGR cooling system and dealers complain they don't have parts to do replacement. This has been going on over a year. I have been told that there have been fires as a result. Can you investigate this situation. Dealers in redding, red bluff, and chico,ca say they do not have parts and don't know when they will get them. Thank you.”

“I own a 2018 ecodiesel and when my truck went in for an oil change they did an update called aem or v08 emissions update. After the update my truck no longer accelerates from a stop. It crawls at under 10mph extremely slow aprox. 90 seconds until the vehicle accelerates. This is extremely dangerous I have been in 3 near accidents due to a lack of acceleration. In addition to the lack of acceleration I now get much lower gas mileage. Prior to the update I was getting 27 mpg, now the best I have gotten was 19mpg. …”

“On february 1, shortly after 9:00 pm central the engine shut off while I was on the interstate. I was in the left hand lane, having just passed as semi a bit earlier. I instinctively tried to start it while it was moving, causing the headlights to go off while I'm doing 75 MPH. At that point started to pull over, though I could barely see the concrete divider and had tried to keep the tires on the rumble strip as I slowed down until I could see the barrier better. Once pulled over, I got it in park, started it, and was able to get home with no issue. …”

“I want to report a safety concern. The concern is already aware by the manufacturer but I want to address the potential risk it put our family in. The recall is known as the vb! Or NHTSA # 19v-757. We bought this truck to have a nice and reliable car to transport our 1 year old child in. Our last 2012 jeep grand cherokee left us stranded in the middle of the rode with our kid due to the computer telling all injectors to stay open and resulting in the motor hydro-locking itself. We took out financing to purchase and the great 2018 ecodiesel dodge Ram. …”

“I was notified of a recall vb1 for the EGR on my ecodiesel, took the truck to the dealership on 1/18/20 for inspection of the EGR. Was informed no parts were available, nor would they be available until at least the end of april. Was informed trucks that used antifreeze coolant due to cracked EGR would get replaced/repaired first. My truck has appetite for coolant, have used a bit over 2 gallons since new. You can smell coolant, one would think there was a leak, was informed it was the cracked EGR. Coolant in the combustion chamber will cause premature engine failure. …”
