One problem related to gasoline engine has been reported for the 2005 Dodge RAM. The most recently reported issues are listed below.
Purchased a 2005 Dodge Ram 1500 on a 3-year lease. The vehicle has 24,000+/- miles. During the last of Jan. 2008 the engine in the vehicle started knocking. I took the vehicle back to the leasing dealer on February 4, 2008. The next day or so, I received a phone call from the dealer service rep. Wanting "proof" of oil changes. I explained that I would not be able to provide receipt's since I do the oil & filter changes myself. I am a farmer and have my own pit built specifically for that purpose. I did not hear anything for another week, I called back and they were still asking for service receipts. Finally contacted Chrysler and a representative said they would have an answer within 24 hours. They called 2 weeks later saying they would not honor the warranty because the oil was filled with sludge and that it was my fault that the engine had failed. I disagree of course and will be pursuing this through the court system. Having own a multitude of vehicles in my 64 year old life, I can assure you that a motor should not go bad after 24,000 miles if the oil had never been changed, which was not the case.
