GMC Envoy TSBs

The Envoy has been assigned 1,405 technical service bulletins (TSB). The 2009 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 GMC to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
