The Ram 3500 has been assigned 548 TSBs over 17 model years.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Dodge to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
A TSB can cover multiple models and years. The 2007 Ram 3500 has been involved in the most campaigns with 42 total service bulletins.
