The Sonic has been assigned 1,508 technical service bulletins (TSB). The 2013 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 Chevrolet to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
