Technical Service Bulletins
Below, we highlight several key 'hidden' protections you may not be aware of, discovered through service campaigns and technical service bulletins. TSBs highlight common potential problems with models and provide corrective measures to dealerships. The items flagged below are of particular note, indicating a potential risk, and a potential correction, should you experience the specific issue. In some cases, an extended warranty may offer additional protection for a particular at-risk component.
