“I have always used synthetic oil in this engine. Just like the many people that I have found on the internet mine threw a rod. Destroyed the core. Estimated cost is 6,000. This is a horrible thing. It appears that Dodge is well aware of this an a recall should have happened long ago.”

“The valve springs in the compression chambers go. As you are driving you suddenly lose power and compression is gone, I have had this happen twice now with 2 chambers each time being gone. It is a scary and dangerous situation. As I ow look to replace the engine after the most recent incident, what I am discovering is that the engines available are available because of the same issue. This seems to be a fairly widespread issue on this 5.7 litre, hemi engine.”

“I was driving my 2004 Dodge RAM 2500 5.9 diesel truck to work during rush hour morning traffic at approximately 25 MPH when the check engine light came on and a few seconds later the truck suddenly accelerated on its own to about 3500rpms. The roads were iced over from a previous snow storm. Due to the sudden acceleration on the ice, the rear tires broke traction and started sliding sideways before I could react to the sudden acceleration. I immediately applied the brakes with no results. …”

“Truck dies while driving and makes it extremely hard to steer ! Seems to be some sort of fuel problem ! This has been ongoing for several years and I don't trust it to attempt to drive in traffic to a dealer for repairs ! The truck currently has approx. 87,000 original miles on it ! Problem seem to start shortly after last dealer visit in 2008 for replacement of A/C ducting under dash ! Dealer shut down right after our president took office, as did many of the local Dodge dealers ! To me, it acts as if the fuel just shuts off. Hard to restart or steer - definitely a safety hazard ! …”

“I own a 2004 Dodge RAM 2500 diesel with a automatic transmission. This occurred on two occasions the first was on saturday 1/31/2015 and the second on monday 2/2/2015. I had just pulled out of my shop when the engine suddenly accelerated at extreme high speed, I slammed on the brakes immediately however as one can imagine the response time and/or the capacity of the braking system was limited due to the high torque of the engine. Non-the-less I was fortunate not to have any other vehicle in my vicinity. This same scenario occur two more time on my way home which is about 4 miles from my shop. …”
