Cadillac DeVille TSBs
The DeVille has been assigned 789 technical service bulletins (TSB). The 2005 model year has been involved in the most bulletins.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Cadillac to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
