After owning for a year, it started idling very rough. Took it to a shop and there was a GM Service Bulletin issued on these cars N192291620 that expired on 6/2026. They would not reimburse me as it expired and car was repaired by a third party. We had only put 500 miles on it since purchasing. It was the Valve Cover Gasket. As we are on a fixed income with a car under 50k miles, this was a big hit for us.
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. This happened while i was driving on the highway and my speed was eratic and I had to cross 2 lanes to get the next exit. The problem has been reproduced my an indepent service center. The PCV vent constantly pulled vacuum (was stuck open to atmosphere) and the sound was only relieved by removing the dip stick. No warning lamps messages or symptoms. There is NO part number difference in the Camshaft cover between model years 2016 thru 2019 Cascadas. I believe that the 2018 should be included in the same Special coverage as the 2016 and 2019 mo…
Vehicle is a 2018 requiring valve cover replacement due to an issue that was recalled on previous years, most recently 2016. Extended warranty was offered for these repairs. TSB Special Coverage N192291620 â Camshaft Cover Replacement (later superseded by N232395320). This should be reviewed for additional recalls.
The contact owns a 2016 Buick Cascada. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormal squealing sound. The vehicle was subsequently taken to the dealer, where it was diagnosed with a PCV valve failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 19,000.
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…
Buick Cascada back window on the convertible tops coming apart, causing flooding inside the car, also there's a danger the window will come out driving down the road. Buick refuses to do anything.

NHTSA’s Office of Defects Investigation opens these when complaints point to a possible safety defect. Many end in a recall.
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 20

In complaints filed with NHTSA for model years 2016–2019, owners most often name: engine, structure, unknown or other. 53 complaints are on record.
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
