When this diesel truck cleans it"S particulate filter I get a strong fuel smell odor in the cab when stopped at a stop light or stop sign. This cleaning of the D.P.R. filter happens every 100 or so miles driven and last for about 20 miles. When the odor occurs my eyes burn, and I cough alot. So far the Dodge dealers are unable to fix my problem. I have taken the pick up truck to two different dealers trying to get relief from this problem.

The contact owns a 2008 Dodge Ram 2500 diesel. The contact stated that he would smell exhaust entering the cab of the vehicle. The odor was so overpowering that it caused irritation to the eyes and illness. The contact stated that the failure was most prominent when the heater was activated and was intermittent. The vehicle was taken to the dealer but the dealer was unable to duplicate the failure. The vehicle was not repaired. The failure mileage was 16,500 and the current mileage was 31,000.

This is the second time this problem happened in 7 months. I was sitting at a light and started to accelerate, the exhaust brake engaged and prevented me from moving forward. I was able to move by slightly depressing the accelerator a little at a time. When I approached my next traffic light, the engine RPM dropped to 500 and then shot up to 1200 rpms. When this happened the truck lurched forward and almost hit a pedestrian in the crosswalk. It also put me half way into a busy intersection. There were multiple close calls that could have caused injury or death. The truck is currently at the dealer again but I am very concerned about this issue. It seems I am not the only person this has happened to.

Exhaust leak into cab of truck is a diesel and actually makes you ill when riding in it. 4 attempts by dealer have failed to rectify problem. I placed a co meter in cab and it went off the scale which goes to 99 ppm.

On my 2008 Dodge Ram 2500 diesel pickup truck sometimes when you accelerate, there is little to no response except black smoke billowing from the exhaust. You have to press the accelerator completely to the floor to get any response, and then it will only do maybe 5-10 mph. Maximum. This happens at random times, and there seems to be no way to predict when it will happen. It happens from a stopped position, as well as accelerating to pass a vehicle at highway speeds. In the case of highway (passing a vehicle) speed, the engine will lose power, but will not completely quit. In either case, you must pull over, turn off the vehicle, and restart it for it to perform normally. This problem first began in late July, 2009. I took the truck to the dealer for repairs on August 14th. 2009. According to the work order (invoice), they replaced a particulate filter, and did a turbo test. The check engine light came back on about 3.5 miles after I left the dealer, and the truck was billowing heavy black smoke. When I took it back to the dealer for the same repair, I was told they were going to do the same thing. A new filter, and a turbo test. They did not have a filter in stock, so they did not make any repairs, and they told me they did not expect this to repair the problem anyway, as it had no affect the last time they did it. The latest incident occurred on October 8, 2009.

Multiple times every month obnoxious smell of burning chemicals in cab when dog filter on diesel goes through regen. Chrysler replaced turbo that was sooted shut. Then they wrapped exhaust. Still does it. Makes you sick.

Epa driven dpf filter on cummins diesel 2008 2500 truck is always causing problems with check engine light. Dealers have had to put a port on turbo, clean exhaust, wrap exhaust, and claim that customers are idling too much. Pollution control devices are obviously bad design. They burn extra diesel in exhaust to burn soot and make mileage go down by 10mpg. 2006 to 2008 change lost significant mpg. The 6.7L engine needs addressing with final fixes that won't continue to make customers go to dealer over and over again for repairs.

I took delivery of my Dodge 2500 mega cab pickup with the cummins 6.7 diesel motor. Almost since the first day, I have had the truck back to the service department at the dealer for a failing emission system. The dpf and regeneration system is constantly clogging and rendering my vehicle undrivable. When this occurs, I return to the dealer, have the part cleaned, or replaced, and I am told that it will occur again. According to my dealers service manager, and Dodge, there is no known fix for this problem. Upon speaking to Dodge customer service regarding a buyback of my vehicle, I have been hung up on, put on hold for hours, told my dealer has to buy it back, or told to hire a lawyer. When researching this matter, I have found that I am not alone with these types of problems with the new 6.7 Dodge trucks. I need to know what recourse I have in this matter with Dodge, or my dealer directly.
