The back window is coming away from the fabric top. Had been getting worse for months. I have complained to gm. I was told to take my car to dealership I did that months ago, when I still had warranty. Nothing was done. I have taken it again to dealership because the window is coming out more. I now have to get it fixed and I have to pay a portion of the cost of a new top, since the…
Tl* the contact owns a 2016 Buick cascada. While driving approximately 1 MPH, the vehicle drove over a curb. When the vehicle was taken to axelrod GMC Buick (parma, oh, 216-661-5060) for an oil change, the technician diagnosed that there was a crack in the frame. The manufacturer was made aware of the failure and sent an investigator to assess the damage. The investigator was unable to determine…
The rear glass window is lifting on the bottom left corner. My husband just noticed it one day. A service bulletin was released by gm in november, 2019 regarding this issue. My insurance won't cover it as it was not caused by an outside force. Safety hazard: if I drive with my windows open and top up, I'm afraid the pressure will cause the window to detach, which would injure any vehicle behind…
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.

Once this bond has started to fail, it is eventually going to lead to the glass completely falling off the car. It is likely that the glass separating…
The rear window of the convertible top starts to pull away from the top itself. Could separate and displace entirely causing damage or injury behind.
The back window on the convertible top has separated from the fabric. 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…
