Selected complaints filed with NHTSA by 2005 Dodge Ram 2500 owners, lightly cleaned up (personal details are redacted by NHTSA).
The room fcm power distribution module corrodes and causes electrical problems. Headlights can go out while driving, taillights, break lights etc. There is many complaints on the web about this issue and dodge has not fixed the problem. I was driving at night and my headlights went completely out. Luckily I was able to avoid any accident and come to a controlled stop. If I had been on a curve I would have lost sight of the road. This is a well known issue among dodge trucks. This is a safety recall as it can cause an accident and death.
Tl* the contact owned a 2005 Dodge Ram 2500. While driving approximately 55 MPH and attempting to avoid crashing into a deer, the contact noticed flames on the rear passenger seat.

Hit brakes to miss a deer drove approx one quarter of mile noticed a bright red glow behind passenger seat upon exiting vehicle noticed flames while darling 911 within minutes entire cab was on fire.
I was driving down the highway in my 2005 Dodge 2500 Ram and smelled smoke. After about 20 seconds I noticed that smoke was beginning to fill the cab. I looked around and saw that the rear passenger-side door was in flames. I immediately pulled over to the shoulder, exited the vehicle, and put out the flames with a blanket. The fire was contained to the door and a little bit of the floor carpet. The very next morning I took it to my local Dodge dealer and about a week later they said that their official report indicated that Chrysler was not at fault and that it was an "act of god". Since then it has been back-and-forth between the dealer and insurance company. The bottom line is it will cost me my deductible ($1000) for something that wasn't my fault. …
All lights (headlights, taillights, etc.) come on while vehicle turned off and turn off while vehicle is running. Also, windshield wipers and washers run all the time and can not be turned off. Drains battery while not running, then will not start. Factory trained mechanic says it is a "bad TIPM" (totally integrated power module), and the dealership can not order a new TIPM as Dodge does not make these anymore (vehicle is 12 years old). My vehicle is practically useless and now valueless, as I can not get needed parts to repair. My experience has been that aftermarket parts (including fan clutch for this vehicle) does not work well and end up needing replacement almost as soon as repairs are done. This really sucks that an American auto manufacturer can fail to make parts available for 12 year old vehicles. I guess they need to sell a new one that bad! Not another Dodge, for sure
I purchased the truck new but over the last several years the truck would go into limp mode or just stall while driving which makes it hard to control because you loose the power steering and brakes. Finally the computer went out, shop ordered a new one and the wipers were going on and off by them selves(has happened before), throwing codes..... The mechanic finally found that the connectors that plug into the computer are bad and loosing connection. This would possible explain the wipers coming on by them selves sometimes when you hit a bump, also the truck stalling. I jumped off the interstate a few months ago and the exit was a turn, when I let off of the accelerator the truck stalled and it was tough to keep it on the road.
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.
