Buick dealership said it was not a covered item under the extended warranty. We tried to glue it back down but it keeps separating all around. Dangerous situation because it could separate completely during travel and cause an accident/injury to others. Should be a recall item since it is being reported by several other Cascada https://plaincars.com/make/buick-cascada https://plaincars.com/make/buick-cascada#complaint-2176965 Sun, 15 Feb 2026 00:00:00 GMT 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. The window has become more and more separated and I'm using glue to hold it on but it's becoming undrivable due to the risk of it separating while on the road. While this has not yet caused an accident, I believe this is one waiting https://plaincars.com/make/buick-cascada https://plaincars.com/make/buick-cascada#complaint-2170921 Wed, 28 Jan 2026 00:00:00 GMT PCV Failure at 62,000 miles. GM extended warranty on 2016 models that demonstrated this problem. Appears to be a design flaw and often fails again after repair. $2000 + job to repair https://plaincars.com/make/buick-cascada https://plaincars.com/make/buick-cascada#complaint-2157452 Mon, 15 Dec 2025 00:00:00 GMT 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. This part was already replaced in my vehicle when the vehicle had roughly 21,000 miles. It has now broken again and it is a systemic issue https://plaincars.com/make/buick-cascada https://plaincars.com/make/buick-cascada#complaint-2154447 Fri, 05 Dec 2025 00:00:00 GMT The contact owns a 2019 Buick Cascada.

Upon examination at the dealership, they determined that the PCV system had failed. The positive crankcase ventilation system caused my Camm to leak and created a vacuum leak which blew out the seals of my vehicle.
