Ram 3500

  • 45,000 miles


Engine revving to 3000 RPM and not idle down. Had to ride brakes put trans in neutral or park to stop. Breaks would not stop truck only slow it. Shop found cod P0606 ECM/PCM communication failure. Why did this not put the truck in limp mode or prevent it from starting. Replaced ECM/PCM control module truck runs fine. Very expensive 3400 dollars.

The contact owns a 2004 Dodge Ram. The contact stated that while driving 20 miles per hour, the vehicle accelerated. The failure previously occurred during rainy weather conditions. The accelerator pedal was not the cause of failure since no pressure was applied to the accelerator pedal. The police were contacted due to the property damage and a report was filed. The contact stated that the vehicle was involved in an crash in 2005 when the brakes did not engage. The contact had not spoken with the manufacturer. The vehicle was under investigation with the insurance company. The vehicle will be towed to the dealer for assessment. The current and failure mileages were not available.

2004 Dodge Ram 3500 pickup cummins 5.9 liter diesel engine. 1/17/2009 under/over acceleration. Vehicle is a "drive by wire" design. Problem happened very sporadically. Would only happen when vehicle and outside air temp was 20 degrees F or lower. Problem happened about 4 times during the winter of 2007-2008. Problem at that time was only under acceleration. I would be driving down the highway at between 55 and 70 mph. The tuck would suddenly not maintain speed and would not accelerate. Pushing the gas pedal all the way to the floor would produce no response from the engine. Check engine light comes on. After a few seconds truck drives normally again. This scenario has happened 8 to 10 times. Over acceleration. This happened twice on 1/13/09. Again truck had been sitting outside all day. Started truck and all was normal for the first 5 or 10 minutes of driving. I was driving down the highway at a steady speed of 60 mph. With no input from me suddenly the truck accelerated very rapidly. The transmission down shifted and the engine RPM jumped up considerably. In my panic I stabbed the brake pedal and was able to slow the truck somewhat. After accelerating wildly for about 1 to 2 seconds the truck then went into the under acceleration mode. Now pushing the gas pedal all the way to the floor would get zero response from the engine. This sudden over acceleration happened again about ten miles further down the road. Luckily the roads were dry and there were no vehicles close enough to me to cause any crash. I replaced the accelerator pedal position sensor and so far the problem has not returned. This is a great concern because of what might have happened during the over acceleration. If the road was snow covered or icy the outcome could have been very serious or even deadly.

Ram 3500 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.
