Dodge RAM 3500 adaptive cruise problems

Filed Jul 17, 2021 · Acceleration · OR

A massive amount of people in forums have encountered the same problem. When you start the vehicle it will idle pretty rough with black smoke. If and when you press the accelerator pedal it will continue to throttle up on its own. In park or driving! FORUM POST: #1. While driving my 04 Dodge 3500 Cummins down the street, at a speed of around 45mph, all of a sudden it went to wide-open throttle. It completely caught me off guard and the first thing I did was hit the brake. It had very little effect on what was happening. In less than 1 block I was well over 70mph with the brake on in a 45mph zone. #2. I had the same exact thing happen, I was at 90 mph on a 40 mph road when I finally had to put it in neutral, the pedal had no effect on rpm as I coasted to a stop the engine sat pegged at the rev limiter, and stayed there until I shut the motor down. I did not have cruise control on or showing as ready to go into the cruise, ie cruise light on in the instrument panel. I had some codes, but not sure when. FUEL PRESSURE TOO HIGH and another I forget. It was scary with the family in the truck. waited a few minutes trying to see that all connections were tight and they were, restarted and all was back to normal. 2 complaints of 1000's. I've been in the mechanical world for 50 years. Everything from motorcycles to heavy equipment and this one took me over a year to figure out. Generally, there are no codes thrown as in mine. The fuel pressure regulator malfunctions and forces pressure on the fuel rail. This feeds the injectors too much fuel and the computer will not default and shut down. I was traveling at 55mph with a 45-foot king pin trailer on my truck. Went to accelerate a bit and took off. At 75 mph, loaded (45000 lbs) I turned the ignition off. How many people has this killed and the possible reason was driver error?

While driving 72 MPH with cruise control on, I hit a bump in the road and the truck started shaking violently, I thought I was going to lose control. I hit the brakes and headed to the shoulder to get off of the busy interstate. When I slowed down, all of a sudden the shaking stopped and I continued on my way.

My driver was traveling at 80 MPH in cruise control when he started to notice a vibration from the truck that was shaking the mirrors. He took the vehicle out of cruise control and started to decelerate. At approximately 70 MPH a large bang was heard from beneath the vehicle and the front end of the truck was lifted off of the pavement. This caused the vehicle to be turned slightly sideways when it came back down into contact with the pavement while traveling at 70 MPH! Thankfully my driver was able to correct the vehicle straight but when he pushed on the brake pedal it went all the way to the floor. He was able to coast the vehicle to the side of the road and eventually bring it to a stop. Parts from the truck had been strewn down the interstate over approximately 200 yds. There was a vehicle traveling behind my driver at the time of the incident but luckily they were far enough behind that they were able to take evasive actions to avoid any flying debris. Thankfully there were no injuries or after incident accidents that occurred though I would attribute this to the alert and responsive driving of both my driver and the driver of the vehicle behind him. Had there been a vehicle directly behind or to the side of him there could have been a major accident possibly resulting in injuries or death. This vehicle was towed to a dodge ram dealer where we were informed that the front drive shaft was the part that failed. We were informed by dealer personnel that this drive shaft has a joint that is non-serviceable nor easily inspected and that this was the root cause of the failure. Other parts that were effected were the transfer case (the case was broken in two pieces and the internals were blown out), transmission cracked beyond repair, brake lines had been severed, fuel lines had been severed and a hole was punched through the cab bottom into the passenger area.

I own a 2008 3500 diesel megacab dually . I was driving along I-70 in colorado at about the speed of 75-80 MPH and had to step on the gas pedal all the way down to get around a semi-truck and as soon as I did this the gas pedal got stuck. I know it wasn't stuck to the floor-mat because I visually saw that it wasn't. I had to slip my shoe off and pull the gas pedal up with my toes due to the shoe not being able to get behind the pedal. By the time I managed to pull the gas pedal back my truck had sped up to about 110-115 MPH.. This is the second time that this has happened to me. Previous to this incident about a week and a half earlier this happened to me in denver as I was be driving through the city. I thought it was the floor-mat then, so I ignored the fact that this had happened but this second time around I did look down to see if it was or not the floor-mat and it was not the floor mat.... I did not have the cruise control on at either time.. Im going to try to contact chrysler and the dealer to try and see what they believe it might be.. Odds are they will think I'm imagining things !!

Erratic windshield wiper performance followed by complete failure of the wipers. Wipers stalled in the center of the windshield in a thunderstorm while towing a 24,000 lb trailer on interstate 65 with semi truck/trailers on 3 sides. This was the 2nd incident of wiper failure. The first failure occurred about 6 months earlier. After leaving the truck parked overnite, the wiper operation returned to normal. I took the truck to my local dodge dealer after both occurrences. They could not find any problems with the wipers after the 1st occurrence while the truck was under warranty. After the 2nd occurrence I was told that the total integrated power module (tipm)had failed and needed to be replaced and since the truck was now out of warranty that I would have to pay for the replacement. I have not yet replaced the tipm. During both wiper failures, the driving situation was very dangerous because road spray covered the windshield and severely cut down visibility. *tr phone interview update (10/01/09): owner took the vehicle in for repairs after tipm (total integrated power module )was diagnosed to be the cause of the wiper failure mode. Owner states that the tipm was replaced and had multiple failure modes occur including : inoperable wipers, flipped turn signals, and inoperable cruise control. The owner took the vehicle back for repairs and the multifunction swithc was replaced. Owner states no further problems.

Cruise control malfunction - 2003 dodge ram 3500, cummins diesel, manual trans. Sept 15th, 2008, 9am I left my home at 3:30 am on my way to denver for work. I used the cruise control through the town of glenwood springs at 55-60 MPH or so, then made my way into the glenwood canyon at just before 4:45 am, which has a posted speed of 50 MPH. There was a construction project in the first tunnel in the canyon, so I tapped the brake and slowed to about 40 MPH, in 6th gear. As I excited the construction area, I hit the 'resume' button for the cruise and the truck began to accelerate (approx 4:47 am). Soon I was going over 70 MPH and accelerating at full throttle. I tapped the brake and the cruise did not turn off... I hit the brake again, harder this time in case I didn't use enough pressure the first time. Again, nothing. At this point the truck is running at 80+ MPH and I'm coming up on a semi in the slow lane, same lane that I'm in. I had to swerve around the tractor-trailer, while at the same time attempting to shut the cruise control off, back on and off again, trying to stop the truck. As I get past the tractor-trailer I'm running well over 80 MPH and I'm starting to panic. I start pumping the brakes over and over, attempting to control the trucks speed around one of the canyon corners. After 30 seconds the truck stopped it's full-throttle attack. I exited the canyon and kept driving for another 10 minutes or so, then pulled over on the side of the freeway. The engine was running at 2000 RPM. I drove to the next exit and parked. Eventually the RPM's dropped to 1500 and I shut it off. I do not feel safe in that truck at all. My wife drives the truck more often than I do, it really scares me to think if she were driving when this happened. This issue was reported to chrysler on the 15th of sept, 2008. Chrysler case# 17902313 trucks there was a required update on the ECM which was done and currently no recalls on this VIN#.
