Selected complaints filed with NHTSA by 2005 Dodge Ram 2500 owners, lightly cleaned up (personal details are redacted by NHTSA).
Turn signal when switched activates the opposite turning light. Rear tail tight housings are not water tight and blows bulbs after raining. Windshield wipers act on their own when its raining and now dome and console lights dont work. No blown fuses. The third fuel pump line is also defective. Will eventually break from vibration. New ones have better vibration housing and dealership had stock. (125 of these and none other because everyone was having the same one break). Key falls out of ignition and rear passenger side door does not lock or unlock when button is pushed. Air bags were recently recalled but they don't have enough part to get it fixed. I must wait. Very unsafe vehicle to be an owner of.
Tl* the contact owns a 2005 Dodge Ram 2500. While driving approximately 80 MPH, the vehicle vibrated abnormally. Within seconds, a loud noise was heard under the vehicle. The driver was able to coast onto the road shoulder and found unknown parts had separated from the vehicle while driving. The vehicle was towed to a dealer where it was diagnosed that the transfer case, constant velocity joint, universal joint, fuel lines, and brakes lines failed. The vehicle was not repaired. The manufacturer was notified. The approximate failure mileage was 270,000.
While driving down highway gasoline started spewing under pressure from top of fuel pump, pulled into parking lot away from other vehicles and waited five to ten minutes before gasoline stopped spraying out. I had to have it towed home where I could check to find out if it was only a rubber hose as I expected or something else. I found out it was a fitting at top of the fuel pump which looks like metal connector where the gasoline was spraying out of a pin hole, I lost about 5 gallons of gas in 14 miles of highway driving.

While driving on my way home from the grocery store I got a real strong diesel smell coming into the cabin, I was half a block away so I kept driving got into my driveway and popped the hood to find injector line #4 leaking like crazy turned the truck off and the next day I went to the dealer and bought two new injector line, replaced the bad one and kept one for spare, another 8 months later the same line went out again, so I replaced it with the spare I had in the truck I went back to the dealer and bought another two, my 3rd one went out a week before halloween while shopping for my 2 year old sons costume I was on the freeway going back home with my wife, my son, and my dad I got the same smell into the cabin and this time I got some smoke into the cabin also I freaked out and got off the freeway and put my wife, son and dad into a taxi and sent them home and I replaced a 3rd …
While driving home from work Friday the #4 fuel tube that comes from the fuel bar and goes into the injectors started leaking causing diesel to leak over my entire motor and undercarriage of vehicle. I drove the vehicle about 20 miles as I did not know there was a leak. I could see smoke coming from what I thought was my exhaust behind the truck but then noticed my fuel gage started going down quickly and when I made it home smoke started coming from under hood. An extreme amount of smoke. About 10 gallons of diesel was leaked out. This could have ignited and / or exploded causing serious injury or death to myself and surrounding vehicles / homes. I was able to find the leak and purchased replacement part from my local Dodge dealership. The parts department told me the #4 tube, which is the one I replaced, was very common to leak. If this is very common...something should be done. …
Shortly after speeding up a car in front of me hit their brakes. When I attempted to slow down it seemed that the accelerator pedal did not return to neutral and it was very hard to stop. After troubleshooting, I found out that the accelerator pedal was sticking and not returning to neutral after being depressed. Sometimes it would slowly return to neutral, other times it would stay depressed. There is no external interference with the pedal (I.e. Floor mat), and only the pedal linkage is at fault. If I pushed the pedal a large distance then it would normally spring back all the to neutral. When I checked closely, it appears that the accelerator pedal position sensor (apps) is what is causing the binding. This truck is throttle-by-wire so no mechanical cable is involved. …
Driving home from work I noticed a strong smell of diesel fuel in the cab, looking in the rearview mirror I noticed that all the cars behind me had slowed down to a distance of approx. 300 feet and white smoke trailing behind the truck. When I had the chance I pulled over in a store parking lot and exited the cab to see fuel pouring out under my truck and white smoke coming out from the left front wheel well. I had the truck towed to closest Dodge dealer where they discovered the number 4 injector line had ruptured and coated the whole engine bay. They also indicted that I was lucky that this did not cause a fire or possibly an accident from the fuel spilling on the roadway. While reading a cummins forum online I have discovered this to be a fairly common problem.
S10 direct reply- letter to the secretary from constituent requesting assistance with a potential safety issue regarding Chrysler vehicle (s); full document not imaged. 2005 Dodge Ram 2500. The consumer stated the gas tank needed to be replaced. The consumer stated he was never able to properly put gas in the vehicle from the day, he purchased it. The consumer stated the first time he attempted to put gas in the vehicle, he could only add four cents at a time without the nozzle shutting off and the gas spilling out. The gas tank was replaced with a used one. However, the replacement tank failed. The consumer stated inferior parts were used which caused the gas tank to leak.
I have an 05 Ram 2500 quad cab Hemi truck with 3,200 miles on it. Since new the truck has had an erratic idle and would occasionally die when shifting from reverse to drive. The PCM has been flashed, the throttle body is projected to be replaced next. This problem is getting progressively worse as the truck recently stalled in traffic three times in a ten minute period. I will also be filling a similar complaint for my 05 Hemi durango limited.
