Complaints grouped by the component NHTSA recorded
Percentages are of component mentions. A single complaint can name more than one component, so these do not sum to the total complaint count.
No recalls in our database for this model year
That does not guarantee a specific vehicle is unaffected — recalls are issued against VINs, and new campaigns are announced regularly. Check a VIN on NHTSA.gov.
Reports submitted to NHTSA, shown in the owner's own words
Loss of power and humming noise from loose cam cover. (Buick Cascada 2016 and 2019 model years had recalls correcting this problem; but not 2017 or 2018 models. All years have the same engines. I think my vehicle should have been recalled.)
Pcv failed causing rough idle, etc light and squeezing sound
Rear convertible top window is separating from the convertible top from regular use and could detach and create a safety problem. This is a well known problem on these cars and Buick did not issue a recall and would not fix it. There was nothing in the owners manual about any preventative actions required.
My Buick Cascada is a 2017 model and has 78,000 miles on it. 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. In reading commentary on line i discovered that this is a known issue with the Cascada models from various years. Other year models have been granted an extended warranty to cover the repair. I feel that if it is an issue with multiple years then multiple years should be covered under the warranty. I was advised not to drive my car very far with the issue it has with the PCV valve and I rely on it to get to work every day which is an hour drive one way. I am now forced to give up my car or get it repaired and pay the ridiculous amount of money they are charging for a part that should be able to be replaced for much less had it not been part of the valve cover. Thank you
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 to happen as many other owners of this vehicle are reporting the same issue. If this would fully separate while on a highway the consequences could be dangerous. This is a chronic manufacturing defect. Buick has indicated the repair would cost between $3,000 and $5,000, which is not possible.
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 with the Buick Cascada. On Google searches, I found similar issues were reported and GM extended the warranty on Buick Cascadas for different years. Both the 2016 and 2019 had a Global Warranty for PCV issues and Camshaft covers. "GLOBAL SAFETY FIELD INVESTIGATIONS [XXX] URGENT - DISTRIBUTE IMMEDIATELY Date: February 16, 2023 Subject: [XXX]- Special Coverage Camshaft Cover The mechanic stated, "the built-in PCV system has failed causing a vacuum issue within the engine and requires the entire camshaft cover to need replacement." It is important to note that General Motors produced this vehicle from 2016 to the 2019 model years and that during these years the camshaft cover/ pcv ( part number 25203562) remained the same and did not change , yet the coverage afforded above is only for the 2016 model year and the 2019 model year. The representative at General Motors confirmed that there is no difference in the processes or part or anything between the 2016 , 2017 , 2018 and 2019 Buick Cascada model years as it relates to the Camshaft cover/PCV and was at a lost to understand why two model years were covered and two model years were left out in the cold. It is a safety risk because the car cannot be driven with a broken camshaft cover/PCV.
Vehicle has rough idle upon start up and randomly rough idle/ acceleration. I have a p0-171 code that comes and goes, Mechanic I took to claims the PCV valve is located in side of the valve cover and feel is the culprit for the issues. Very high vacuum inside engine at this point. No whistling like some have mentioned but if you pull the oil fill or dipstick engine wants to quit and you can tell there is a large vacuum. This is a 2017 cascada and seems to align up with all of the issues that were noted in the complaints. Looking for an extended warranty to get this remedied. Thankyou for your time. current mileage is 90k miles
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. The recall, N192291620 only covered the 2016 however the 2017 has the same engine and experienced the same problem. The car was brought to the dealer and they confirmed the problem. The dealer said the only way to repair was to replace the parts, cost for repair approx $2300.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
Complaint and recall counts across every year of this model
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
