Selected complaints filed with NHTSA by 2007 Dodge Ram 3500 owners, lightly cleaned up (personal details are redacted by NHTSA).
As I was traveling the highway, my engine starting smoking. I was extremely fortunate that I was coming up on a service center/grocery store in idaho. There was indication on my dash instruments that my truck was operating abnormally, other than the smoke sifting through the hood. Upon my pulling over onto the the side, I opened the hood with used of heavy gloves and a towel and checked to see if radiator had fluid as the indicator light had read normal. As expected, coolant spewed out. I immediately closed it and waited for it tobe towed into idaho falls to be checked by a shop that I was familiar with.
Smoke started coming from the hood. I opened the hood and the engine had caught fire
While towing a fifthwheel trailer I noticed smoke in the cabin and stopped the truck. Upon opening the hood I found a fire at the firewall on the right side behind the engine. Failing to be able to extinguish the flames I separated the truck and trailer and pushed the truck away from the trailer and dialed 911. The truck was a total lose and after contacting Dodge I was told that my truck had already had the recall performed (08V641000) and that they had never had any further problems with these vehicles. Clearly the recall failed to correct the problem at the very least in this case. Chrysler sent an inspector ([redacted]) out to investigate and inspect the truck, his report stated that there were no material defects found. I have a copy of that report if you need. Chrysler has refused to honor the warranty on this vehicle as well. …

60 miles from home after a 2,000 mile camping trip the truck suddenly stopped. Traveling north on highway191 in yellowstone park the dash lights started to flash and the truck died. I was barely able to pull off the narrow road. Emergency flashers didn't work and there was no cellphone service, snow was falling and trucks barely able to get around us, we feared for our lives. I opened up the hood and smelled burning plastic, the TIPM was melted in spots. Finally a kind motorist stopped to see if we needed help, 20 miles further down the road he was able to call a towing service which took another several hours to get to us. We were towed to a Dodge dealership in bozeman where it will be another2 weeks before they can get it in.
TIPM (totally integrated power module) failed, causing vehicles engine to stall at 75mph on freeway. Condition resulted in a "no-start" scenario. Because of this failed TIPM, the onboard diagnostic computer has no power, resulting in an inability to diagnose with obdii scan tools. This situation could have resulted in a possibly fatal accident, as the vehicle was in motion at 75mph on a major freeway with moderate traffic. When the vehicle stalled, all power steering and brakes were lost. These parts are prone to failing, but Chrysler refuses to accept responsibility. An aftermarket replacement is available at the price of approx. $600, but these parts are special order, and take several days to receive.
