The RAV4 Hybrid has been assigned 54 TSBs over 3 model years.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Toyota 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 2018 RAV4 Hybrid has been involved in the most campaigns with 29 total service bulletins.
