Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Ram 2500

  • 116,000 miles


My 2004 Dodge Ram 2500 diesel pick up truck suddenly loses power and stalls while traveling on highway and entering highway. First occurrence entering highway truck restarted and continued to run. 2nd occurrence next day on highway truck restarted but travelled short distance and stalled again in the road. Towed to dealer. Dealer replaced batteries and battery wiring and truck started, but when test driven by dealer the vehicle continued to stall. Dealer now believes fuel pump or "module" may be cause but is having trouble testing due to manufacturer change in wiring. Dealer reports that Chrysler made a mid year fuel pump "modification" to 2004 models while in production at Chrysler and that while wiring is similar to 2005 year, the color coding used on the modification does not match the 2004 or 2005 color coding. Dealer has requested wiring schematic from Chrysler for the 2004 modification but to date Chrysler has been unable to provide any information. Vehicle is unsafe to operate on road since stalling can occur at any time without warning. Vehicle remains in shop at Chrysler dealer with problem unsolved. All maintenance on this vehicle has been done by Chrysler dealerships. No previous issues with fuel system or stalling.

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. The check engine light came on at the time of the first occurrence. I let the truck sit for a couple days, however needed to plow out from a large snowstorm. Upon restarting the truck, the check engine light was off and everything was back to normal. Things changed approximately a half hour into plowing when the sudden acceleration occurred once again and this time within inches of ending up in the drainage ditch at the end of my driveway. It occurred two more times as I was completing the plowing. Also, out of the blue it would idle down with no response when I depressed the accelerator, then after a moment or two it would respond. During the idle the voltage meter would drop to just about zero. I did find some references to the apps (accelerator pedal position sensor) on the web, however when I checked in with my local dealer they stated that they had no recall notice on this. After experiencing this, there is no doubt in my mind that this is quite a serious matter and should be looked into. This situation could easily cause injury or death. I have forty years of driving experience and have never encountered anything of this sort before. I will be taking the vehicle to the dealership, however I feel quite strongly that this should be covered under a recall.

Ram 2500 4WD 6-cyl

  • 123,000 miles
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 continued to slide sideways into the oncoming lane of traffic when as sudden as the acceleration happened, the rpms dropped down to an idle and I was able to get the truck under control. Luckily, there were no other vehicles in the oncoming lane. Dealership has truck now and is telling me the fault code indicates a bad acceleration pedal position sensor. If there would have been any vehicles in the oncoming lane of traffic at the time the truck accelerated on its own, it would have absolutely caused an accident and could have killed someone. I have never felt so panicked when the truck took off on its own. I cannot describe the feeling of helplessness I felt when this happened. If it hasn't happened already, this will certainly, at some point cause a tragic accident with the loss of life if not addressed immediately. I have read several online blogs where this seems to be an issue in other 2004 Dodge Ram 2500 5.9 diesel trucks. These trucks need to be recalled immediately and parts re-designed to not allow a sudden increase in acceleration.

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.

Ram 2500

  • 70,000 miles
Problem 1) the engine has a exhaust manifold leak. This is due to Dodge using inadequate bolts on the head and the bolts broke. The removal of the exhaust manifold requires the bolts to be drilled and tapped out. Dodge should have corrected this problem but would not. Problem 2) the vehicle leaks profusely in the cab. Ever since I bought this vehicle the cab has leaked. It leaks under the rear seat and it leaks from the front visor as well. I have tried to seal with rtv since Dodge could never fix the problem. It still leaks. Problem 3) the passenger front window works intermittently at best. Problem 4) the rear doors will not release the child lock function. I have tried numerous times but apparently the switch in the door does not work.

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.
