What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There was a high pitched whistle/squeal type noise I was hearing and was told by the Buick dealership that it is an issue with the PCV valve failing. To replace this it will cost over $2,000 because of the design of where the valve is housed it is part of a much larger piece.
The rear window of this car has separated and when I contacted the manufacturer they indicated a service bulletin was issued but they are not liable for the repair.
I brought the 2017 Buick Cascada in for repair following rough idle and check engine light. This vehicle only has 46,200 miles. The mechanic put it to the computer and the mechanic found the issue that was ultimately identified as the camshaft cover/pc valve.
The component is the PCV and manifold. Cracks develop in the PCV pressure regulator and manifold creating a situation where excess air was drawn into the engine intake. This caused the engine to run rough and unpredictable. This is a known defect and the 2016 model with the same engine was recalled.
A squealing sound was coming from the top of my engine and I had low/rough idle and it progressed to a low voltage output and check engine lights. I was able to use GM's Special Coverage Adjustment N232395320 Camshaft Cover (for the 2019 Cascada) and Special Coverage Adjustment N192291620 Camshaft Cover Replacement…
The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the knock combustion vibration control system had failed. The dealer determined that the valve cover, the PCV valve, the head gasket, and an unknown part needed to be replaced.
The contact stated that while driving at various speeds, there was an abnormal squealing sound coming from the vehicle. There was no warning light illuminated. The vehicle was taken to an independent mechanic where it was discovered that the diaphragm inside the PCV (Positive Crankcase Ventilation) valve had ruptured.
The back glass window separated from the canvas roof, it started in the bottom corner of the glass window.
