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

  • 225,000 miles
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.

10 minutes after start up I began to travel in drive gear of automatic transmission. Upon acceleration the pedal was dead, I.e. no power. The engine was running fine. After the truck decelerated to about 10 mph the pedal was back and working. This happened again after about 20 seconds. This behavior continued for 30 minutes and stopped. It was colder that morning (10 degrees F). The pedal also had run away acceleration at times before the pedal went dead. I thought it was fuel related but that doesn't explain the run away acceleration. I believe it an electrical problem with the apps system? very scary though. I hope it doesn't die crossing and intersection.

Our 2004 Dodge Ram 2500 spontaneously caught on fire last night while parked in the driveway. We had not driven it for two days, the keys were not in the ignition, no one was near it...it just went up in flames. My husband could not put the fire out so we called 911 and the fire department finally got the fire put out. The truck is totaled, just a charred metal frame at this point. Had the vehicle been parked in the garage, we would be dead.

  • Automatic transmission
  • 50,100 miles
The contact owns a 2004 Dodge Ram 2500. While driving 30 mph, the warning lights illuminated and the accelerator pedal extended to the floor. The contact was unable to avoid running a red light. The dealer stated that the computer needed to be reset. The failure recurred and the dealer stated that the throttle sensor needed to be replaced at the cost of $450. The failure mileage was 50,100 and current mileage was 50,114. Updated 04/23/08. After the dealer replaced a part, the consumer still experienced the same problem. The dealer then told the consumer there may be a short in the wiring harness under the dash that goes to the cruise control and the dash would need to be taken apart to fix the wiring. Updated

Ram 2500 4WD 8-cyl

  • Automatic transmission
  • 42,000 miles
: the contact stated while the brake pedal was applied, the brakes pulsate. The dealership turned the rotors when this occurred. The rotors must be turned every 6,000-10,000 miles. Also, after starting the vehicle and putting it into gear, the vehicle surged forward. The brake pedal was applied and the vehicle was put into neutral, but the engine continued to rev. The vehicle was put into park and turned off, upon turning the vehicle on; a lightning bolt was on the dashboard. The engine continued to rev and the vehicle was turned off. When the vehicle was restarted it operated properly. The dealership was unable to determine any codes on the computer, but determined the warning light meant something triggered the throttle. The vehicle surged a second time.
