    Default 2016 - 2017 Cadillac CTS-V: Service Bulletin:


    Certain 2016-2017 model year Cadillac CTS-V vehicles, equipped with 6.2L engine (RPO LT4), may have a condition in which the engine air filter element does not have glue beads across the paper pleating. If this condition is present the pleats can fold over on themselves during high-RPM aggressive driving, and restrict the airflow, which may collapse the air duct and cause the engine to stall. Additionally, the air duct could be cut and a malfunction indicator lamp could illuminate with diagnostic trouble codes P0121-00, P2101-00 and P2119-00 stored.


    Replace the air filter element and, if necessary, replace the air duct.

    The bulletin is attached below:
