This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs. Condition Special Coverage Adjustment Some 2016 model year Buick Cascada vehicles, equipped with a 1.6L engine, may have a condition where cracks can develop in the diaphragm of the Positive Crankcase Ventilation (PCV) pressure regulator valve. This valve is a part of the engine camshaft cover. If this were to occur, excess air could be drawn into the engine intake. As a result, the engine may run rough, especially during idle, the Malfunction Indicator Light (Check Engine Light) would illuminate and a diagnostic trouble code for Fuel Trim Lean (P0171) or other airflow related DTC would set. This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after September 9, 2020, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to September 9, 2020, must be submitted to the Service Contract provider. Correction Vehicle owners or lessees who paid for repairs referenced in this Special Coverage (“Customers”) are eligible for reimbursement of their reasonable and customary expenses in accordance with the procedures specified below. The conditional right to reimbursement is provided by GM solely in the interest of customer satisfaction and is personal to Customers. Customers may not assign and GM does not consent to any assignment of any Customer’s right to submit reimbursement claims, or to receive reimbursement, or any other rights granted by this Special Coverage to any third party, including but not limited to service contract providers, and this Special Coverage is not intended to and does not confer any third party beneficiary, subrogation or contribution rights, or any other rights to reimbursement, against GM, whether in law, equity or otherwise, on any third parties. Dealers are to replace the engine camshaft cover as necessary. The repairs will be made at no charge to the customer.

A vehicle may come in with DTC P0171 – Fuel Trim System Lean, or other airflow-related DTCs. The vehicle may also exhibit rough engine operation or stalling at idle. Following the diagnostics in SI for that DTC may lead to the PCV system as a potential source of external airflow. 2. Confirm a bad PCV valve. 2.1 Remove the engine cover. Refer to Engine Cover Replacement in SI. 2.2 Check to make sure the engine oil dipstick is fully seated and the oil fill cap is fully tightened. 5509278 2.3 With the engine running, listen for noise coming from the PCV valve, shown above. If noise is heard, check to see if the noise gets quieter or disappears with the engine oil dipstick removed. 2.4 Reinsert the dipstick. 2.5 Check to see if there is vacuum at the PCV vent at the front of the PCV valve by placing a piece of tissue near it. The tissue will be sucked against the vent and held if vacuum is present. • If the PCV valve is making noise and there is vacuum present at the PCV valve vent, replace the Camshaft Cover. Refer to Camshaft Cover Replacement in SI.
