Two problems related to engine exhaust system have been reported for the 2006 Dodge Ram 3500. The most recently reported issues are listed below.
The contact owns a 2006 Dodge Ram 3500. The contact stated that while in the cabin, diesel exhaust could be smelled. The vehicle was taken to a mechanic where the failure could not be replicated. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 183,000.
The flap that controls fresh air vs. Re-circulated air breaks and falls off. Even if replaced it quickly breaks again. Dodge charges $800 to fix this cheap plastic part only for it to quickly break again. I found the problem because of the numerous reports found on the web about Dodge ac low air flow. When broke, the flap falls on top of the fan motor and blocks air circulation. My children have bad allergies and I have no way of turning off the outside air because of the defective design in the flap. After it breaks it blocks the air flow of the fan motor. I have 3 CO-workers with the same model vehicle. They have all since checked their fresh air/re-circulate air flaps and they were all broke. This obviously is a design flaw not being acknowledged by Dodge. It's hazardous to my children health (and mine) not being able to turn off the outside air when traveling through areas with bad air outside, exhaust fumes from other cars, etc. . . . Thank you for looking into this matter.
